BYG20GHM3_A/I Equivalent & Substitute Parts

Part Overview

The BYG20GHM3_A/I is an avalanche diode rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 400 V DC reverse voltage and 1.5 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as Active and carries automotive-grade qualification under AEC-Q101. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the BYG20GHM3_A/I is determined by strict equivalence across the following critical parameters:

Voltage Rating: 400 V DC reverse voltage (Vr) maximum
Current Rating: 1.5 A average rectified current (Io)
Forward Voltage: 1.4 V maximum at 1.5 A forward current
Reverse Recovery Time: 75 ns
Reverse Leakage Current: 1 µA at 400 V
Package: DO-214AC (SMA) surface mount configuration
Technology: Avalanche diode classification
Compliance: ROHS3 compliance and MSL 1 rating

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the main part number. Packaging format variations (Tape & Reel, Cut Tape & Digi-Reel) do not affect electrical performance or circuit functionality.

Engineering Selection Recommendations

All listed substitute parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain Active product status. The BYG20GHM3_A/I and BYG20GHE3_A/H both carry automotive-grade qualification under AEC-Q101 standard, suitable for applications requiring automotive compliance. The BYG20G-E3/TR and BYG20G-E3/TR3 variants are functionally equivalent but do not carry explicit automotive qualification designation in the provided specifications.

Selection between substitute parts should be based on:

Automotive Requirements: BYG20GHM3_A/I and BYG20GHE3_A/H are qualified to AEC-Q101
Packaging Format: BYG20G-E3/TR (Cut Tape & Digi-Reel), BYG20G-E3/TR3 (Tape & Reel), BYG20GHM3_A/I (Tape & Reel), BYG20GHE3_A/H (Tape & Reel)
Inventory Availability: All parts are in stock with varying quantities

All substitute parts comply with ROHS3 regulations and carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can BYG20G-E3/TR be used as a direct replacement for BYG20GHM3_A/I?

A: Yes. Both parts share identical electrical specifications: 400 V reverse voltage, 1.5 A average rectified current, 1.4 V forward voltage at 1.5 A, 75 ns reverse recovery time, and 1 µA reverse leakage current at 400 V. Both use DO-214AC (SMA) surface mount packaging. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel).

Q: What is the difference between BYG20GHE3_A/H and BYG20GHM3_A/I?

A: Both parts are electrically and mechanically identical with matching voltage, current, and thermal specifications. Both carry AEC-Q101 automotive qualification. The difference lies in manufacturing lot designation and packaging reel configuration.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL 1 rating.

Q: Does packaging format affect circuit performance?

A: No. Packaging format variations (Cut Tape & Digi-Reel, Tape & Reel, Tape & Reel with different reel types) do not affect electrical performance, thermal characteristics, or circuit functionality. Format selection is determined by assembly equipment and procurement requirements.

Q: Which substitute part should be selected for automotive applications?

A: BYG20GHM3_A/I and BYG20GHE3_A/H both carry AEC-Q101 automotive qualification. BYG20G-E3/TR and BYG20G-E3/TR3 are electrically equivalent but do not carry explicit automotive qualification in the provided specifications.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that packaging format compatibility with assembly equipment is confirmed. All substitute parts maintain identical electrical performance and thermal operating range (-55°C to 150°C junction temperature).
