SS22SHE3_A/H Equivalent & Substitute Parts Reference

Part Overview

The Vishay SS22SHE3_A/H is a Schottky rectifier diode designed for automotive and general-purpose surface mount applications, with a maximum reverse voltage of 20 V and a continuous forward current rating of 2 A. The device features fast recovery speed and is fully qualified to AEC-Q101 standards. As the SS22SHE3_A/H is listed as discontinued at Digi-Key, sourcing original stock may be challenging. Identifying direct replacement or parametric equivalent parts is necessary for continued product availability and design support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS22SHE3_A/H are identified strictly based on matching electrical and mechanical parameters, compliance, and certifications. The allowed parameters for substitution include: technology (Schottky), maximum reverse voltage (20 V), average rectified current (2 A), maximum forward voltage (550 mV @ 2A), recovery speed, reverse leakage current, capacitance, grade (automotive), qualification (AEC-Q101), mounting type, package/case (DO-214AC, SMA), supplier device package, operating temperature range, RoHS/REACH status, and moisture sensitivity level (MSL). Only parts matching all specified parameters are listed as direct substitutes or parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

SS22SHE3_B/H and SS22SHE3_B/I are suitable substitutes for the SS22SHE3_A/H based on complete matching of all provided electrical, mechanical, compliance, and certification parameters. Both substitutes are fully RoHS compliant, AEC-Q101 qualified, and maintain the same form factor and electrical ratings. Selection between them may proceed based solely on product status and inventory availability.

Frequently Asked Questions (FAQ)

Q1: What is the most critical factor when selecting a substitute for SS22SHE3_A/H?
A1: The most critical factors are strict matching of electrical parameters (voltage, current, forward voltage drop, reverse leakage, speed), mechanical package (DO-214AC, SMA), qualification (AEC-Q101), automotive grade, and compliance statuses.

Q2: Are SS22SHE3_B/H and SS22SHE3_B/I form-fit-function compatible with SS22SHE3_A/H?
A2: Yes. Both SS22SHE3_B/H and SS22SHE3_B/I match the electrical, mechanical, and package parameters of SS22SHE3_A/H.

Q3: Are there any differences in compliance or certification between these substitute parts?
A3: No. All listed substitutes hold the same RoHS3, REACH, automotive grade, and AEC-Q101 qualifications as the original part.

Q4: Do substitute parts support the same mounting and application method?
A4: Yes. All parts are for surface mount applications in the DO-214AC (SMA) package and support identical mounting and application arrangements.

Q5: Does operating temperature or environmental qualification differ among these parts?
A5: No. All listed parts have the same operating junction temperature range and environmental qualification status.

Q6: What actions are required when the main part is discontinued?
A6: Selection of substitute parts with identical parameters and compliance ensures design continuity without modifications. Use available part numbers SS22SHE3_B/H and SS22SHE3_B/I as direct replacements.
