Vishay SE30AFBHM3/6B Equivalent & Substitute Parts Reference (Diodes, Rectifiers)

Part Overview

The Vishay General Semiconductor SE30AFBHM3/6B is an active surface-mount diode rectifier designed for general-purpose use in applications requiring a maximum reverse voltage of 100V and an average rectified current of 1.4A. The device features standard recovery speed, automotive grade qualification (AEC-Q101), and is supplied in a DO-221AC (SlimSMA) package, with ROHS3 and REACH compliance. Identifying qualified substitute models with matching electrical and mechanical parameters is essential for maintaining supply continuity, manufacturing flexibility, and design compatibility in automotive and surface-mount rectifier applications.

Substitute Part Grouping Explanation

Substitution is based strictly on parametric equivalence in electrical performance, mechanical format, compliance, and automotive qualification. The substitute diodes listed below match the SE30AFBHM3/6B in the following key criteria: reverse voltage, average rectified current, forward voltage rating, recovery speed, reverse recovery time, reverse leakage current, capacitance, AEC-Q101 qualification, RoHS and REACH status, mounting style, and package type. Only those parts matching all these specified parameters are considered equivalent substitutes.

Engineering Selection Recommendations

When selecting an equivalent substitute for the Vishay SE30AFBHM3/6B, consider only those options which maintain status as active products, meet ROHS3 and REACH compliance, and provide the specified AEC-Q101 automotive qualification where required. Both SE30AFBHM3/6A and SE30AFB-M3/6A match the electrical and mechanical parameters, with SE30AFBHM3/6A also maintaining the automotive grade and AEC-Q101 status.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical in determining equivalent rectifier diodes for SE30AFBHM3/6B?
A1: Only voltage rating, current rating, forward voltage at rated current, recovery speed, reverse recovery time, reverse leakage, capacitance, package type (DO-221AC, SlimSMA), mounting type, operating temperature, compliance (ROHS3, REACH), moisture sensitivity level, and automotive/AEC-Q101 qualification if specified.

Q2: Is matching the AEC-Q101 qualification and automotive grade necessary for all applications?
A2: For automotive applications and designs requiring AEC-Q101 qualification, substitute parts must provide both automotive grade and AEC-Q101 certification per the input criteria.

Q3: Can SE30AFB-M3/6A be used as a drop-in substitute for SE30AFBHM3/6B?
A3: SE30AFB-M3/6A matches all key electrical and mechanical parameters except for automotive grade and explicit AEC-Q101 qualification.

Q4: Is there any difference in package or mounting style among the substitutes?
A4: All substitutes specified here utilize the DO-221AC (SlimSMA) package and surface mount configuration.

Q5: What compliance requirements do the listed substitutes meet?
A5: All substitutes are ROHS3 compliant, REACH unaffected, and have an unlimited moisture sensitivity level (MSL 1). Only SE30AFBHM3/6A specifies both automotive grade and AEC-Q101 qualification.
