Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESH2BHE3_A/I are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 930 mV @ 2 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 175°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements, ensuring functional interchangeability within the specified application envelope. Variations in secondary parameters such as reverse recovery time (trr), reverse leakage current, and capacitance do not preclude substitution when primary ratings align.

Engineering Selection Recommendations

ESH2B-E3/5BT (Vishay General Semiconductor - Diodes Division)

This substitute maintains all critical electrical parameters and package specifications. The device carries Active product status with ROHS3 compliance and MSL 1 rating. Inventory availability is 10,300 pieces. The reverse recovery time specification of 35 ns represents a 40% increase relative to the main part; however, this remains within the fast recovery classification threshold. This part is suitable for applications where Vishay product continuity is preferred.

PU2BBH (Taiwan Semiconductor Corporation)

This substitute provides equivalent electrical performance with matching reverse recovery time (25 ns) and improved reverse leakage characteristics (2 µA @ 100 V). The device carries Active product status, ROHS3 compliance, automotive-grade qualification under AEC-Q101, and MSL 1 rating. Inventory availability is 5,205 pieces. This part is suitable for applications requiring cross-manufacturer sourcing flexibility while maintaining automotive-grade specifications.

Both substitute parts are qualified for direct replacement based on electrical equivalence, mechanical compatibility, and regulatory compliance alignment with the main part.

Frequently Asked Questions (FAQ)

Q: What determines whether a diode can substitute for the ESH2BHE3_A/I?

A: Substitution is determined by matching the following parameters: 100 V DC reverse voltage rating, 2 A average rectified current, 930 mV forward voltage at 2 A, fast recovery speed classification (≤ 500ns), DO-214AA (SMB) package, surface mount mounting type, -55°C to 175°C operating temperature range, ROHS3 compliance, and MSL 1 rating. All identified substitutes meet these requirements.

Q: Are there differences in reverse recovery time between the main part and substitutes?

A: Yes. The ESH2BHE3_A/I and PU2BBH both specify 25 ns reverse recovery time. The ESH2B-E3/5BT specifies 35 ns. All three devices remain classified as fast recovery diodes (≤ 500ns, > 200mA). The difference does not affect substitution eligibility based on the provided parameters.

Q: Can I use PU2BBH in an automotive application?

A: Yes. The PU2BBH carries automotive-grade qualification under AEC-Q101 standard, matching the main part ESH2BHE3_A/I. Both devices are suitable for automotive applications.

Q: What is the difference in reverse leakage current specifications?

A: The ESH2BHE3_A/I specifies 10 µA @ 50 V. The ESH2B-E3/5BT and PU2BBH both specify 2 µA @ 100 V. Lower leakage current at higher voltage represents improved performance characteristics. This difference does not preclude substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance status, matching the main part ESH2BHE3_A/I.

Q: Can I mix these parts in the same assembly?

A: Yes. All parts share identical electrical ratings, package specifications, and compliance certifications. They are mechanically and electrically interchangeable within the specified application envelope.

Q: What is the moisture sensitivity level for these diodes?

A: All parts, including the main part and substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
