Engineering Selection Recommendations

All three substitute parts—ESH2D-E3/52T, ESH2D-E3/5BT, and ESH2DHE3_A/H—are direct electrical and mechanical equivalents to the ESH2D-M3/5BT. Each maintains identical voltage, current, and thermal specifications within the DO-214AA surface mount package.

ESH2D-E3/52T and ESH2D-E3/5BT are standard-grade rectifier diodes with specifications matching the main part across all critical parameters. Both are Active products with ROHS3 compliance and unlimited moisture sensitivity rating.

ESH2DHE3_A/H is qualified to AEC-Q101 automotive standards and features a reduced reverse recovery time of 25 ns compared to the 35 ns specification of the main part. This device is suitable for applications requiring automotive-grade qualification while maintaining all other electrical and mechanical compatibility.

Selection between these substitutes depends on application requirements: standard industrial applications accept any of the three parts, while automotive applications requiring AEC-Q101 qualification specify ESH2DHE3_A/H.

Frequently Asked Questions (FAQ)

Q: Can ESH2D-E3/52T, ESH2D-E3/5BT, and ESH2DHE3_A/H be used interchangeably with ESH2D-M3/5BT?

A: Yes. All three substitute parts maintain identical electrical ratings (200 V reverse voltage, 2 A average rectified current, 930 mV forward voltage drop), identical reverse recovery time specifications (35 ns for the first two parts), identical package type (DO-214AA SMB), and identical compliance certifications (ROHS3, MSL 1). Direct substitution is supported in circuit applications.

Q: What is the difference between ESH2DHE3_A/H and the other substitute parts?

A: ESH2DHE3_A/H carries AEC-Q101 automotive qualification and features a reverse recovery time of 25 ns, which is 10 ns faster than the 35 ns specification of ESH2D-M3/5BT and the other substitutes. All other electrical and mechanical parameters remain identical. This part is specified for automotive applications requiring automotive-grade component qualification.

Q: Are there any package or mounting differences between these parts?

A: No. All parts, including the main part ESH2D-M3/5BT and all substitutes, use the DO-214AA (SMB) surface mount package. Mounting type, footprint, and PCB assembly compatibility are identical across all parts.

Q: What compliance certifications apply to all these parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). ESH2DHE3_A/H additionally carries AEC-Q101 automotive qualification. All parts are classified as Active product status.

Q: Can I substitute ESH2DHE3_A/H in a non-automotive application?

A: Yes. ESH2DHE3_A/H maintains all electrical and mechanical specifications required for standard applications. The automotive qualification is an additional certification that does not restrict use in non-automotive circuits. The faster reverse recovery time (25 ns) is a performance advantage in any application.
