Substitute Part Grouping Explanation

Substitution of the ES2D-13 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 2 A minimum
Package / Case: DO-214AA, SMB (surface mount)
Mounting Type: Surface Mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Parameters:

Reverse Recovery Time (trr): ≤ 50 ns preferred for fast recovery applications
Operating Temperature Range: Must encompass or exceed -55°C to 150°C
RoHS Compliance: ROHS3 Compliant preferred for new designs

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical and Mechanical Specifications): Parts that match or exceed all primary substitution criteria with identical or superior performance characteristics.

Functional Equivalents (Acceptable Performance Variations): Parts that meet primary substitution criteria but may exhibit variations in secondary parameters such as reverse recovery time, forward voltage, or reverse leakage current within acceptable engineering tolerances for the DO-214AA SMB package class.

Engineering Selection Recommendations

Primary Recommendation: ES2D-13-F

The ES2D-13-F from Diodes Incorporated is the direct functional equivalent of the ES2D-13. This part maintains identical electrical specifications including 200 V reverse voltage, 2 A average rectified current, 920 mV forward voltage at 2 A, and 25 ns reverse recovery time. The ES2D-13-F is currently in active production status with ROHS3 compliance, addressing the discontinuation of the original ES2D-13. Inventory availability is substantial at 130,906 pieces.

Secondary Recommendations for 2 A Applications:

MURS220T3G (onsemi): Meets all primary substitution criteria with 200 V reverse voltage and 2 A current rating. Features ROHS3 compliance and extended operating temperature range (-65°C to 175°C). Reverse recovery time of 35 ns is within fast recovery classification. Reverse leakage current of 2 µA is superior to the ES2D-13. High inventory availability at 100,100 pieces.

STTH2R02U (STMicroelectronics): Provides 200 V reverse voltage and 2 A current rating in DO-214AA SMB package. Features 30 ns reverse recovery time and 3 µA reverse leakage current. ROHS3 compliant with 43,020 pieces in stock. Forward voltage of 1000 mV at 2 A represents a 80 mV increase compared to ES2D-13.

ER2D-LTP (Micro Commercial Co): Rated for 200 V reverse voltage and 2 A current. Reverse recovery time of 35 ns and forward voltage of 950 mV at 2 A provide close performance alignment. Extended operating temperature range of -65°C to 175°C. ROHS3 compliant with 198,400 pieces available.

ROHS3 compliant with 89,400 pieces in inventory. Reverse leakage current of 10 µA is higher than ES2D-13 but acceptable for general-purpose rectification.

Alternative for Current-Reduced Applications:

MURS120T3G (onsemi): Suitable where 1 A average rectified current is acceptable. Maintains 200 V reverse voltage rating with superior reverse leakage current of 2 µA. Extended temperature range and ROHS3 compliance. Highest inventory availability at 340,400 pieces.

Not Recommended:

S2D (Diotec Semiconductor): While rated for 200 V and 2 A, this part exhibits standard recovery characteristics with 1500 ns reverse recovery time, significantly exceeding the fast recovery specification of the ES2D-13. Forward voltage of 1150 mV at 2 A represents a 230 mV increase. Suitable only for applications where fast recovery is not required.

STTH1R02U (STMicroelectronics): Current rating of 1.5 A is below the 2 A requirement of the ES2D-13. Suitable only for applications with reduced current demands.

STTH4R02U (STMicroelectronics): Current rating of 4 A exceeds the 2 A specification. Suitable for applications requiring higher current capacity but represents oversizing for ES2D-13 replacement.

CURB203-G (Comchip Technology): Meets voltage and current specifications but exhibits 50 ns reverse recovery time and 1000 mV forward voltage at 2 A, both representing performance degradation relative to ES2D-13. Limited inventory at 4,128 pieces.

Frequently Asked Questions (FAQ)

Q: Can ES2D-13-F be used as a direct replacement for ES2D-13?

A: Yes. The ES2D-13-F maintains identical electrical specifications including 200 V reverse voltage, 2 A average rectified current, 920 mV forward voltage at 2 A, and 25 ns reverse recovery time. The primary difference is ROHS3 compliance and active production status. Both parts use the DO-214AA SMB package with identical pinout and footprint.

Q: What is the significance of reverse recovery time in selecting a substitute?

A: Reverse recovery time (trr) determines how quickly the diode transitions from forward conduction to reverse blocking. The ES2D-13 specifies 25 ns, classified as fast recovery. Substitutes with trr values up to 50 ns remain within fast recovery classification (≤ 500ns, > 200mA). The S2D with 1500 ns trr is standard recovery and unsuitable for applications requiring fast switching characteristics.

Q: Are all substitute parts available in the same SMB package?

A: Yes. All listed substitute parts use the DO-214AA SMB package, ensuring mechanical and thermal compatibility. Surface mount orientation and footprint are identical across all alternatives.

Q: What is the impact of forward voltage variation among substitutes?

A: Forward voltage variations affect power dissipation and thermal performance. The ES2D-13 specifies 920 mV at 2 A. Substitutes range from 875 mV (MURS120T3G at 1 A) to 1150 mV (S2D at 2 A). Higher forward voltages increase power loss according to P = Vf × I. For 2 A applications, differences of 30-80 mV represent acceptable variations in general-purpose rectification circuits. Applications with tight thermal budgets should prioritize lower forward voltage options.

Q: Which substitute offers the best reverse leakage current performance?

A: MURS120T3G and MURS220T3G from onsemi both specify 2 µA reverse leakage at 200 V, superior to the ES2D-13 at 5 µA. STTH series parts from STMicroelectronics specify 3 µA. Lower reverse leakage reduces standby current and improves circuit efficiency in applications with extended idle periods.

Q: Can MURS120T3G be used in place of ES2D-13?

A: MURS120T3G is suitable only for applications where 1 A average rectified current is acceptable. The ES2D-13 is rated for 2 A. Using a 1 A part in a 2 A circuit risks thermal stress and premature failure. MURS120T3G is not a direct substitute but an alternative for reduced-current applications.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant parts?

A: RoHS non-compliant parts (ES2D-13) may contain restricted substances including lead, cadmium, and hexavalent chromium. ROHS3 compliant parts meet Directive 2011/65/EU restrictions on hazardous substances. For new designs and applications subject to environmental regulations, ROHS3 compliant substitutes are required. All active substitute options listed are ROHS3 compliant.

Q: How does operating temperature range affect substitute selection?

A: The ES2D-13 operates from -55°C to 150°C. Several substitutes offer extended ranges: ER2D-LTP, MURS120T3G, and MURS220T3G extend to -65°C to 175°C. Extended temperature ranges provide design margin for applications in extreme environments. Applications limited to -55°C to 150°C can use any listed substitute without thermal derating.

Q: Is STTH2R02U a suitable replacement for ES2D-13?

A: Yes. STTH2R02U provides 200 V reverse voltage and 2 A current rating with 30 ns reverse recovery time and 3 µA reverse leakage current. Forward voltage of 1000 mV at 2 A represents an 80 mV increase, resulting in approximately 160 mW additional power dissipation at 2 A. ROHS3 compliance and 43,020 pieces in inventory support production continuity.

Q: What inventory considerations apply to substitute selection?

A: Inventory availability varies significantly. ER2D-LTP offers the highest availability at 198,400 pieces, followed by MURS120T3G at 340,400 pieces. ES2D-13-F provides 130,906 pieces. CURB203-G has limited availability at 4,128 pieces. For high-volume production, prioritize substitutes with substantial inventory reserves to ensure supply continuity.

Q: Can ES2D from Good-Ark Semiconductor be used as a substitute?

A: Yes. ES2D provides 200 V reverse voltage and 2 A current rating with 35 ns reverse recovery time and 950 mV forward voltage at 2 A. Reverse leakage current of 10 µA is higher than ES2D-13 but acceptable for general-purpose rectification. ROHS3 compliance and 89,400 pieces in inventory support production use.
