Engineering Selection Recommendations

Parametric Equivalents - Direct Replacement:

ESH2D-E3/52T, ESH2D-E3/5BT, ESH2DHE3_A/H, and PU2DBH are parametric equivalents suitable for direct substitution in applications using ESH2DHE3_A/I. These parts maintain the 200 V reverse voltage rating, 2 A average rectified current, and DO-214AA surface mount package. ESH2DHE3_A/H and PU2DBH retain automotive-grade qualification and AEC-Q101 certification identical to the main part. ESH2D-E3/52T and ESH2D-E3/5BT exhibit slightly elevated reverse recovery time (35 ns versus 25 ns) but maintain all other electrical specifications. All parametric equivalents carry ROHS3 compliance and MSL 1 rating.

Manufacturer-Recommended Equivalent - Application-Dependent:

RS2D-13-F from Diodes Incorporated is a manufacturer-recommended substitute with the following distinctions: reduced average rectified current (1.5 A versus 2 A), elevated forward voltage (1.3 V @ 1.5 A versus 930 mV @ 2 A), and significantly extended reverse recovery time (150 ns versus 25 ns). The operating temperature range is narrower (-65 to 150°C versus -55 to 175°C). This part is suitable only for applications where the 1.5 A current rating is sufficient and the elevated reverse recovery time does not compromise circuit performance. RS2D-13-F does not carry automotive-grade qualification or AEC-Q101 certification.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. Parts ESH2DHE3_A/H and PU2DBH preserve automotive-grade qualification and AEC-Q101 certification required for automotive applications. Selection of non-automotive-qualified substitutes (ESH2D-E3/52T, ESH2D-E3/5BT, RS2D-13-F) is restricted to non-automotive circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ESH2D-E3/52T or ESH2D-E3/5BT be used as direct replacements for ESH2DHE3_A/I?

A: Yes. Both parts maintain identical voltage (200 V), current (2 A), forward voltage (930 mV @ 2 A), and package specifications (DO-214AA, SMB). The reverse recovery time is 35 ns compared to 25 ns in the main part. This 10 ns difference is acceptable in general-purpose rectifier applications where switching speed is not a critical constraint. Both parts are ROHS3 compliant with MSL 1 rating.

Q: Is RS2D-13-F a suitable substitute for ESH2DHE3_A/I?

A: RS2D-13-F is a manufacturer-recommended equivalent with reduced current rating (1.5 A versus 2 A) and elevated reverse recovery time (150 ns versus 25 ns). This part is suitable only for applications where the circuit operates at or below 1.5 A average rectified current and where the extended reverse recovery time does not degrade circuit performance. RS2D-13-F lacks automotive-grade qualification and AEC-Q101 certification, restricting its use to non-automotive applications.

Q: What is the difference between ESH2DHE3_A/H and ESH2DHE3_A/I?

A: Both parts are manufactured by Vishay and share identical electrical specifications: 200 V reverse voltage, 2 A average rectified current, 930 mV forward voltage, 25 ns reverse recovery time, and 2 µA reverse leakage current. Both carry automotive-grade qualification and AEC-Q101 certification. The parts differ only in manufacturing lot or packaging designation. ESH2DHE3_A/H is a direct parametric equivalent suitable for applications requiring automotive qualification.

Q: Can PU2DBH from Taiwan Semiconductor Corporation replace ESH2DHE3_A/I?

A: Yes. PU2DBH maintains all critical electrical parameters: 200 V reverse voltage, 2 A average rectified current, 930 mV forward voltage, 25 ns reverse recovery time, and 2 µA reverse leakage current. The capacitance is 33 pF versus 30 pF, a negligible difference. PU2DBH carries automotive-grade qualification and AEC-Q101 certification. The part is ROHS3 compliant with MSL 1 rating and is suitable for direct substitution in automotive and non-automotive applications.

Q: Are all substitute parts available in the same DO-214AA (SMB) package?

A: Yes. All substitute parts listed—ESH2D-E3/52T, ESH2D-E3/5BT, ESH2DHE3_A/H, RS2D-13-F, and PU2DBH—are packaged in DO-214AA (SMB) surface mount configuration. No PCB layout or footprint modifications are required for substitution.

Q: Which substitute parts retain automotive qualification?

A: ESH2DHE3_A/H and PU2DBH retain automotive-grade qualification and AEC-Q101 certification identical to ESH2DHE3_A/I. These parts are suitable for automotive applications. ESH2D-E3/52T, ESH2D-E3/5BT, and RS2D-13-F do not carry automotive qualification and are restricted to non-automotive circuit applications.

Q: What is the significance of the 25 ns versus 35 ns reverse recovery time difference?

A: Reverse recovery time (trr) determines the speed at which a diode transitions from forward conduction to reverse blocking. ESH2DHE3_A/I, ESH2DHE3_A/H, and PU2DBH exhibit 25 ns recovery time, while ESH2D-E3/52T and ESH2D-E3/5BT exhibit 35 ns. The 10 ns difference is acceptable in general-purpose rectifier applications. In high-frequency switching circuits or applications with stringent EMI requirements, the faster 25 ns recovery time may be preferred. RS2D-13-F exhibits 150 ns recovery time, suitable only for low-frequency applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts—ESH2D-E3/52T, ESH2D-E3/5BT, ESH2DHE3_A/H, RS2D-13-F, and PU2DBH—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the main part ESH2DHE3_A/I.
