Substitute Part Grouping Explanation

Substitution of the ES2BA-13 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AC, SMA (Surface Mount)
Mounting Type: Surface Mount

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: Tolerance range 920 mV to 1.1 V @ 2 A
Reverse Recovery Time (trr): Range 25 ns to 1.5 µs
Current - Reverse Leakage @ Vr: ≤ 5 µA @ 100 V

Engineering Selection Recommendations

Primary Recommendation: ES2BA-13-F

The ES2BA-13-F is the direct parametric equivalent manufactured by Diodes Incorporated. This part maintains identical electrical specifications to the ES2BA-13, including 100 V reverse voltage, 2 A average rectified current, 920 mV forward voltage at 2 A, and 25 ns reverse recovery time. The ES2BA-13-F carries Active product status and ROHS3 compliance, addressing regulatory requirements absent in the discontinued ES2BA-13. Inventory availability of 34,605 units supports production continuity. This part is suitable for direct replacement in all applications previously using the ES2BA-13.

Secondary Recommendation: SA2B-E3/61T

The SA2B-E3/61T, manufactured by Vishay General Semiconductor, meets all primary equivalence criteria with 100 V reverse voltage and 2 A average rectified current in DO-214AC SMA packaging. This part exhibits standard recovery characteristics (1.5 µs trr) compared to the fast recovery profile of the ES2BA-13, resulting in higher forward voltage (1.1 V @ 2 A) and lower reverse leakage (3 µA @ 100 V). The SA2B-E3/61T is Active status with ROHS3 compliance and provides the highest inventory availability at 30,200 units. Selection of this part is appropriate for applications where switching speed requirements do not mandate fast recovery performance.

Tertiary Recommendation: SA2B-E3/5AT

The SA2B-E3/5AT is functionally equivalent to SA2B-E3/61T with identical electrical specifications and Tape & Reel packaging. This part is suitable where tape and reel format is preferred over bulk reel configurations. Inventory availability of 8,343 units supports moderate-volume applications.

Not Recommended for New Designs: ES2B-LTP

The ES2B-LTP, manufactured by Micro Commercial Co, carries a "Not For New Designs" product status designation. Although this part meets electrical equivalence criteria, its design status precludes selection for new product development. Existing designs currently utilizing this part may continue operation, but migration to Active-status alternatives is advised for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can ES2BA-13-F be used as a direct replacement for ES2BA-13?

A: Yes. The ES2BA-13-F is a parametric equivalent with identical voltage rating (100 V), current rating (2 A), forward voltage (920 mV @ 2 A), reverse recovery time (25 ns), and package (DO-214AC SMA). The primary difference is product status: ES2BA-13-F is Active and ROHS3 compliant, whereas ES2BA-13 is discontinued and RoHS non-compliant.

Q: What is the difference between fast recovery and standard recovery diodes in this product group?

A: Fast recovery diodes (ES2BA-13, ES2BA-13-F, ES2B-LTP) exhibit reverse recovery times ≤ 500 ns, enabling operation at higher switching frequencies with reduced switching losses. Standard recovery diodes (SA2B-E3/5AT, SA2B-E3/61T) have reverse recovery times > 500 ns (1.5 µs in this case), resulting in higher forward voltage and lower reverse leakage. Selection depends on circuit switching frequency requirements.

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

A: Yes. All substitute parts use the DO-214AC SMA surface mount package, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. Packaging format (Cut Tape, Digi-Reel, or Tape & Reel) varies by supplier but does not affect component performance.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations. The original ES2BA-13 is RoHS non-compliant. All recommended substitutes (ES2BA-13-F, SA2B-E3/5AT, SA2B-E3/61T) are ROHS3 compliant, meeting regulatory requirements for products sold in regulated markets. ES2B-LTP is also ROHS3 compliant but carries "Not For New Designs" status.

Q: Can SA2B-E3/61T replace ES2BA-13 in high-frequency switching applications?

A: SA2B-E3/61T is suitable for general-purpose rectification but exhibits standard recovery characteristics (1.5 µs trr) versus the fast recovery profile (25 ns trr) of ES2BA-13. In applications requiring fast switching or operating at frequencies above 100 kHz, the longer recovery time may introduce additional switching losses and heat generation. For such applications, ES2BA-13-F is the appropriate selection.

Q: What operating temperature range should be considered when selecting a substitute?

A: The ES2BA-13 operates from -55°C to 150°C junction temperature. ES2BA-13-F, SA2B-E3/5AT, and SA2B-E3/61T maintain this identical range. ES2B-LTP extends the range to -65°C to 175°C, providing additional thermal margin for extreme environment applications. Verify circuit thermal design requirements before selecting parts with extended temperature ranges.

Q: Is inventory availability a factor in part selection?

A: Inventory availability supports production scheduling and supply chain continuity. SA2B-E3/61T offers the highest availability at 30,200 units, followed by ES2BA-13-F at 34,605 units. For high-volume production, these parts provide supply security. ES2B-LTP (9,494 units) and SA2B-E3/5AT (8,343 units) support moderate-volume requirements.
