ESH2PC-M3/85A Equivalent & Substitute Parts

Part Overview

The ESH2PC-M3/85A is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the eSMP® series. This surface mount diode operates at 150 V DC reverse voltage with a 2 A average rectified current rating and is packaged in the DO-220AA (SMP) form factor. The device is currently in active product status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative part numbers within this family provide identical or equivalent functional characteristics while accommodating different packaging formats or qualification requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ESH2PC-M3/85A is determined by equivalence across the following critical parameters:

Voltage Rating: DC reverse voltage of 150 V (maximum)
Current Rating: Average rectified current of 2 A
Forward Voltage Drop: 980 mV maximum at 2 A forward current
Reverse Recovery Time: 25 ns
Reverse Leakage Current: 1 µA at 150 V
Junction Capacitance: 25 pF at 4 V, 1 MHz
Package Type: DO-220AA surface mount form factor
Temperature Range: -55°C to 175°C junction operating range
Compliance Status: RoHS3 compliant, REACH unaffected

Substitute parts ESH2PC-M3/84A and ESH2PCHM3/84A maintain identical electrical specifications and mechanical compatibility. Packaging format differences (Tape & Reel versus Cut Tape) and automotive qualification (AEC-Q101) represent the primary distinctions among equivalent devices.

Engineering Selection Recommendations

All three diodes—ESH2PC-M3/85A, ESH2PC-M3/84A, and ESH2PCHM3/84A—are active products with identical electrical and thermal specifications. Selection between these parts is determined by application requirements and supply chain considerations rather than functional performance differences.

ESH2PC-M3/85A and ESH2PC-M3/84A are functionally equivalent standard-grade devices supplied in Tape & Reel packaging. Both maintain RoHS3 compliance and unlimited moisture sensitivity classification, suitable for general industrial and commercial applications.

ESH2PCHM3/84A provides the same electrical performance with AEC-Q101 automotive qualification and is supplied in Cut Tape packaging. This variant is appropriate for automotive applications requiring formal qualification documentation and traceability.

Packaging format selection (Tape & Reel versus Cut Tape) depends on assembly process requirements and volume considerations. All devices operate across the identical temperature range (-55°C to 175°C junction) and maintain equivalent reverse recovery characteristics (25 ns) for fast switching applications.

Frequently Asked Questions (FAQ)

Q: Are ESH2PC-M3/85A, ESH2PC-M3/84A, and ESH2PCHM3/84A electrically interchangeable?

A: Yes. All three devices maintain identical voltage ratings (150 V), current ratings (2 A), forward voltage drop (980 mV @ 2 A), reverse recovery time (25 ns), and reverse leakage current (1 µA @ 150 V). Electrical performance is equivalent across all specified parameters.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging provides components on cut sections of carrier tape, typically used for lower volumes or manual assembly processes. Both formats use the same DO-220AA component body.

Q: When should ESH2PCHM3/84A be selected instead of ESH2PC-M3/85A?

A: ESH2PCHM3/84A includes AEC-Q101 automotive qualification, which is required for automotive applications subject to automotive industry standards. If your application requires automotive-grade components with formal qualification documentation, ESH2PCHM3/84A is the appropriate selection.

Q: Do all three parts have the same moisture sensitivity level?

A: Yes. All three devices are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any compliance differences between these parts?

A: All three parts are RoHS3 compliant and REACH unaffected. ESH2PCHM3/84A additionally carries AEC-Q101 automotive qualification. Standard compliance status is identical across all three devices.

Q: Can ESH2PC-M3/85A be used in applications originally designed for ESH2PCHM3/84A?

A: Electrical and thermal specifications are identical, enabling functional substitution in circuit design. However, if the original application requires AEC-Q101 automotive qualification documentation, ESH2PCHM3/84A must be retained to maintain compliance requirements.

Q: What is the operating temperature range for all three devices?

A: All three diodes operate across a junction temperature range of -55°C to 175°C, providing identical thermal performance characteristics.
