ES2C-13 Equivalent & Substitute Parts

Part Overview

The ES2C-13 is a superfast recovery rectifier diode manufactured by Diodes Incorporated, rated for 150 V DC reverse voltage and 2 A average rectified current in a Surface Mount SMB (DO-214AA) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The ES2C-13 operates across a junction temperature range of -55°C to 150°C and features a reverse recovery time of 25 ns, making it suitable for fast-switching applications. Due to its discontinued status and RoHS non-compliance, alternative parts with equivalent electrical performance and improved compliance status are required for new designs and ongoing production.

Substitute Part Grouping Explanation

Substitution of the ES2C-13 is determined by equivalence in the following critical parameters:

Voltage Rating: Reverse voltage (Vr) must equal or exceed 150 V
Current Rating: Average rectified current (Io) must equal or exceed 2 A
Package Type: Surface Mount SMB (DO-214AA) or compatible package
Speed Classification: Fast Recovery technology with reverse recovery time ≤ 500 ns for currents > 200 mA
Forward Voltage: Maximum forward voltage drop at rated current
Reverse Leakage: Maximum reverse leakage current at rated reverse voltage
Temperature Range: Operating junction temperature range must accommodate application requirements

Substitute parts are grouped into two categories:

Parametric Equivalents maintain identical electrical specifications and package footprint, differing only in compliance status or packaging format (bulk vs. tape & reel).

Manufacturer Recommended Alternatives provide equivalent electrical performance with variations in specific parameters (forward voltage, reverse recovery time, or temperature range) while maintaining functional compatibility within the 150 V / 2 A / SMB package classification.

Engineering Selection Recommendations

ES2C-13-F (Diodes Incorporated) is the primary parametric equivalent for direct replacement. This part maintains identical electrical specifications (150 V, 2 A, 25 ns reverse recovery time, 920 mV forward voltage) and package footprint (DO-214AA, SMB). The ES2C-13-F is currently active in production with ROHS3 compliance and REACH unaffected status, providing improved regulatory compliance over the discontinued ES2C-13. Packaging is supplied in Tape & Reel format.

ES2CA-13-F (Diodes Incorporated) provides parametric equivalence with an alternative package format. This part uses the DO-214AC (SMA) package instead of SMB, resulting in a different footprint. Electrical specifications remain identical to the ES2C-13. Selection of this part requires PCB layout modification to accommodate the SMA package. ROHS3 compliance and REACH unaffected status are maintained.

ES2C (Diotec Semiconductor) is a manufacturer-recommended alternative with minor electrical variations. Forward voltage is reduced to 900 mV @ 2 A (20 mV improvement), and reverse recovery time is improved to 20 ns (5 ns faster). Operating temperature range is slightly reduced (-50°C minimum vs. -55°C). This part maintains DO-214AA (SMB) package compatibility and ROHS3 compliance. Inventory availability is substantial at 43,700 pieces.

MURS115T3G (onsemi) is a manufacturer-recommended alternative currently in Last Time Buy status. This part maintains 150 V / 2 A ratings and SMB package compatibility. Electrical performance differs: forward voltage is 875 mV @ 1 A (lower than ES2C-13 at 2 A), reverse recovery time is 35 ns (10 ns slower), and reverse leakage is reduced to 2 µA. Operating temperature range is extended to -65°C to 175°C. ROHS3 compliance is confirmed. Last Time Buy status indicates limited future availability.

For new designs requiring long-term supply assurance and regulatory compliance, ES2C-13-F is the recommended selection. For applications with existing SMB footprints and cost optimization, ES2C (Diotec) provides improved electrical performance. The MURS115T3G is suitable only for applications where extended temperature range (-65°C) is required and where Last Time Buy procurement constraints are acceptable.

Frequently Asked Questions (FAQ)

Q: Can ES2C-13-F directly replace ES2C-13 without PCB modification?

A: Yes. The ES2C-13-F maintains identical electrical specifications and uses the same DO-214AA (SMB) package footprint. No PCB layout changes are required for direct substitution.

Q: What is the difference between ES2C-13-F and ES2CA-13-F?

A: Both parts are parametric equivalents with identical electrical performance. The primary difference is package format: ES2C-13-F uses DO-214AA (SMB), while ES2CA-13-F uses DO-214AC (SMA). The SMA package has a different footprint and requires PCB layout modification. Selection depends on available PCB space and design constraints.

Q: Why is the ES2C (Diotec) listed as a substitute if it has different electrical specifications?

A: The ES2C (Diotec) maintains functional equivalence within the 150 V / 2 A / SMB classification. The variations in forward voltage (900 mV vs. 920 mV) and reverse recovery time (20 ns vs. 25 ns) represent improvements in performance rather than degradation. These differences are within acceptable tolerances for most applications using the ES2C-13. Functional compatibility is confirmed by the manufacturer recommendation.

Q: Is MURS115T3G suitable for new production designs?

A: The MURS115T3G is currently in Last Time Buy status, indicating that onsemi will discontinue this part. While it provides functional equivalence, it is not recommended for new production designs requiring long-term supply assurance. Use this part only for legacy product support or applications where extended temperature range (-65°C to 175°C) is a critical requirement.

Q: What compliance differences exist between ES2C-13 and its substitutes?

A: The ES2C-13 is RoHS non-compliant and REACH affected. All recommended substitutes (ES2C-13-F, ES2CA-13-F, ES2C, and MURS115T3G) are ROHS3 compliant. The ES2C-13-F and ES2CA-13-F are REACH unaffected, while ES2C has REACH information available upon request, and MURS115T3G is REACH unaffected. For applications requiring RoHS3 compliance, any substitute is acceptable.

Q: Can I use MURS115T3G in place of ES2C-13 if my application requires lower forward voltage?

A: The MURS115T3G has a forward voltage of 875 mV @ 1 A, which is lower than the ES2C-13 at 920 mV @ 2 A. However, forward voltage specifications are measured at different current levels, making direct comparison imprecise. The MURS115T3G is functionally compatible for 150 V / 2 A applications. Verify that the lower forward voltage does not create thermal or circuit performance issues in your specific application.

Q: What is the minimum operating temperature for each substitute?

A: ES2C-13-F and ES2CA-13-F: -55°C. ES2C (Diotec): -50°C. MURS115T3G: -65°C. If your application requires operation below -50°C, use either ES2C-13-F, ES2CA-13-F, or MURS115T3G. The ES2C (Diotec) is limited to -50°C minimum.

Q: Are there inventory or lead time considerations for these substitutes?

A: ES2C-13-F has 3,005 pieces in stock. ES2CA-13-F has 10,300 pieces. ES2C (Diotec) has 43,700 pieces. MURS115T3G has 10,100 pieces. The ES2C (Diotec) offers the highest inventory availability. MURS115T3G is in Last Time Buy status, which may affect future availability.
