Substitute Part Grouping Explanation

Substitute parts for the ES1PDHM3/85A are identified based on strict electrical and mechanical parameter equivalence within the eSMP® series. The substitution logic is determined by the following criteria:

Critical Parameters for Substitution:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 920 mV @ 1 A
Reverse Recovery Time (trr): 25 ns
Current - Reverse Leakage @ Vr: 5 µA @ 200 V
Capacitance @ Vr, F: 10 pF @ 4V, 1MHz
Package / Case: DO-220AA
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts maintain identical electrical specifications and package compatibility. Parts designated with automotive grade and AEC-Q101 qualification are grouped separately from non-automotive variants to preserve application-specific requirements.

Regulatory Compliance: All parts are ROHS3 Compliant, REACH Unaffected, and carry MSL rating of 1 (Unlimited). All parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Frequently Asked Questions (FAQ)

Q: Can ES1PD-M3/85A be used as a direct substitute for ES1PDHM3/85A?

A: ES1PD-M3/85A provides identical electrical specifications and package compatibility. However, ES1PD-M3/85A lacks automotive-grade designation and AEC-Q101 qualification. Use ES1PD-M3/85A only in applications where automotive qualification is not required.

Q: What is the difference between ES1PDHM3/85A and ES1PDHM3/84A?

A: Both parts carry automotive-grade designation and AEC-Q101 qualification with identical electrical parameters and DO-220AA package compatibility. The difference lies in manufacturing date code designation (85A versus 84A). Both are functionally equivalent for circuit design purposes.

Q: Are all substitute parts compatible with the DO-220AA package footprint?

A: Yes. All listed substitute parts use DO-220AA (SMP) package designation with surface mount mounting type. PCB footprint compatibility is maintained across all substitutes.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 Compliant with MSL rating of 1 (Unlimited). REACH status is Unaffected for all parts. Automotive-grade parts (ES1PDHM3/85A and ES1PDHM3/84A) carry AEC-Q101 qualification.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: All parts share identical reverse recovery time (trr) of 25 ns and fast recovery speed classification (≤500 ns, >200 mA). Electrical performance in switching applications is equivalent across all substitutes.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across junction temperature range of -55°C to 150°C. This range is identical across all substitute options.
