Equivalent & Substitute Parts for ES3DHM3_A/I

Part Overview

The ES3DHM3_A/I is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This diode is classified as Active product status with AEC-Q101 automotive qualification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design flexibility, or application-specific packaging preferences.

Substitute Part Grouping Explanation

Substitution of the ES3DHM3_A/I is determined by strict equivalence in the following electrical and mechanical parameters:

Voltage Rating: Reverse voltage must equal 200 V DC maximum
Current Rating: Average rectified current must equal 3 A
Forward Voltage: Maximum forward voltage at 3 A must not exceed 900 mV
Reverse Recovery Time: Must support fast recovery characteristics (≤ 500 ns for currents > 200 mA)
Reverse Leakage Current: Must not exceed 10 µA at 200 V
Package: Must be DO-214AB (SMC) surface mount configuration
Operating Temperature Range: Must support -55°C to 150°C junction temperature
Compliance: RoHS3 compliance and automotive-grade qualification (AEC-Q101) are required for direct substitution in automotive applications

Substitute parts are grouped into two categories: Vishay variants (same manufacturer, different packaging or tape configurations) and Cross-manufacturer equivalents (alternative manufacturers meeting identical electrical and mechanical specifications).

Engineering Selection Recommendations

Primary Substitutes (Identical Electrical and Compliance Profile):

ES3DHE3_A/H and ES3DHE3_A/I are direct substitutes for ES3DHM3_A/I. Both parts maintain identical electrical specifications, automotive-grade classification, and AEC-Q101 qualification. These variants differ only in tape configuration (Tape & Reel packaging). Selection between these three Vishay automotive-qualified variants depends on packaging and inventory availability.

Secondary Substitutes (Equivalent Electrical Performance, Automotive-Qualified):

ACEFC304-HF (Comchip Technology) meets all electrical requirements with improved reverse recovery time (20 ns versus 30 ns) and slightly lower capacitance (40 pF versus 45 pF). This part carries automotive-grade designation and AEC-Q101 qualification, making it suitable for automotive applications requiring the ES3DHM3_A/I specification.

Non-Automotive Alternatives (Electrical Equivalents Without Automotive Qualification):

ES3D-E3/57T, ES3D-E3/9AT, ES3D-M3/57T, and ES3D-13-F provide electrical equivalence but lack automotive-grade classification and AEC-Q101 qualification. These parts are suitable only for non-automotive applications or where automotive qualification is not a design requirement. Selection among these variants is based on packaging format (Cut Tape vs. Tape & Reel) and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ES3D-E3/57T be used as a direct replacement for ES3DHM3_A/I in automotive applications?

A: No. While ES3D-E3/57T is electrically equivalent, it lacks automotive-grade classification and AEC-Q101 qualification. For automotive applications, use ES3DHE3_A/H, ES3DHE3_A/I, or ACEFC304-HF.

Q: What is the difference between ES3DHM3_A/I and ES3DHE3_A/I?

A: Both parts are identical in electrical specifications, package type (DO-214AB), and automotive qualification. The difference is in tape configuration and inventory availability. ES3DHE3_A/I has significantly higher stock (55,100 pcs) compared to ES3DHM3_A/I (827 pcs).

Q: Is ACEFC304-HF a suitable substitute if faster reverse recovery is required?

A: ACEFC304-HF has a reverse recovery time of 20 ns compared to 30 ns for ES3DHM3_A/I. If faster switching is required, ACEFC304-HF meets this criterion while maintaining all other electrical specifications and automotive qualification.

Q: Can I use ES3D-13-F (Diodes Incorporated) in place of ES3DHM3_A/I?

A: ES3D-13-F is electrically equivalent but is not automotive-grade and lacks AEC-Q101 qualification. Use only in non-automotive applications or where automotive qualification is not required.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, Digi-Reel) affects only handling, storage, and assembly processes. All variants in this comparison maintain identical electrical performance within their respective qualification levels.

Q: What is the minimum reverse recovery time among all substitutes?

A: ACEFC304-HF has the fastest reverse recovery time at 20 ns. All other substitutes maintain 25 ns to 30 ns, which is within the fast recovery specification (≤ 500 ns for currents > 200 mA).
