ESH2PC-M3/84A Equivalent & Substitute Parts

Part Overview

The ESH2PC-M3/84A is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount diode operates at 150 V DC reverse voltage with a 2 A average rectified current rating and features fast recovery characteristics with a 25 ns reverse recovery time. The component is housed in a DO-220AA (SMP) package and is classified as an active product 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESH2PC-M3/84A are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 980 mV @ 2 A
• Reverse Recovery Time (trr): 25 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 150 V
• Capacitance @ Vr, F: 25 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: DO-220AA
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and represents a logistics variation only. Automotive qualification (AEC-Q101) is an additional certification that does not disqualify a part from substitution but indicates enhanced reliability screening.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical equivalence to the ESH2PC-M3/84A. Selection between the main part and substitutes is determined by application requirements and supply chain considerations:

ESH2PC-M3/84A (Tape & Reel): Standard general-purpose rectifier diode suitable for non-automotive applications. Active product status with ROHS3 compliance and unlimited MSL rating. Appropriate for high-volume production environments utilizing automated tape-and-reel handling.

ESH2PCHM3/84A (Cut Tape, AEC-Q101): Identical electrical and mechanical specifications with additional automotive-grade qualification per AEC-Q101 standard. Cut tape packaging format is suitable for lower-volume or manual assembly operations. The automotive qualification indicates enhanced reliability screening and is applicable to automotive and mission-critical applications where AEC-Q101 certification is specified.

Both substitute parts are active products from the same manufacturer with identical core electrical performance. The choice between Tape & Reel and Cut Tape packaging reflects assembly methodology and volume requirements rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can ESH2PCHM3/84A replace ESH2PC-M3/84A in any application?

A: Yes. The ESH2PCHM3/84A maintains identical electrical parameters (150 V reverse voltage, 2 A average rectified current, 25 ns reverse recovery time, 980 mV forward voltage drop) and mechanical compatibility (DO-220AA surface mount package). The primary difference is packaging format (Cut Tape versus Tape & Reel) and the addition of AEC-Q101 automotive qualification. Electrical and mechanical substitution is direct.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated assembly. Cut Tape (CT) packaging supplies the same components on shorter tape segments, suitable for lower-volume or manual assembly operations. Both formats contain identical components in the same DO-220AA package with no electrical or mechanical differences.

Q: Does AEC-Q101 qualification affect electrical performance?

A: No. AEC-Q101 is a reliability qualification standard that certifies enhanced screening and testing procedures. The ESH2PCHM3/84A with AEC-Q101 qualification delivers identical electrical specifications to the standard ESH2PC-M3/84A. AEC-Q101 qualification is required for automotive applications and mission-critical systems where enhanced reliability documentation is specified.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the main part ESH2PC-M3/84A and all identified substitutes (ESH2PC-M3/84A and ESH2PCHM3/84A) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these diodes be used interchangeably in PCB assembly?

A: Yes, within packaging format constraints. All parts use the DO-220AA surface mount package with identical pin configuration and footprint. Tape & Reel and Cut Tape formats contain the same physical component and are mechanically interchangeable on the PCB. Assembly equipment compatibility depends on whether the production line is configured for Tape & Reel or Cut Tape input.

Q: What is the reverse recovery time specification and why does it matter?

A: Reverse recovery time (trr) of 25 ns indicates the diode is classified as a fast recovery rectifier. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking when the applied voltage reverses. Fast recovery characteristics reduce switching losses in high-frequency applications and are critical in power supply and inverter circuits.
