SS32-M3/9AT Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS32-M3/9AT is a surface mount Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates at 20 V DC reverse voltage with 3 A average rectified current capacity in a DO-214AB (SMC) package. The part is classified as Active and maintains full compliance with RoHS3 and REACH regulations. Alternative equivalent parts are necessary to address supply chain flexibility, packaging format preferences, and inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS32-M3/9AT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 500 µA @ 20 V
• Mounting Type: Surface Mount
• Package / Case: DO-214AB, SMC
• Operating Temperature - Junction: -55°C to 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) represents the only variable among equivalent parts and does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—SS32-M3/9AT, SS32-E3/57T, SS32-E3/9AT, and B320-13-F—are electrically and mechanically equivalent for direct substitution in applications requiring a 20 V, 3 A Schottky rectifier diode in DO-214AB (SMC) surface mount package.

Selection Criteria Based on Provided Data:

1. Vishay SS32 Series (SS32-M3/9AT, SS32-E3/9AT, SS32-E3/57T): All three Vishay variants share identical electrical specifications and base product number SS32. Selection among these three depends on packaging format preference and inventory availability. SS32-E3/9AT offers the highest inventory level (3800 pcs) in Tape & Reel format. SS32-E3/57T provides Cut Tape & Digi-Reel packaging for applications requiring smaller quantity handling.

2. Diodes Incorporated B320-13-F: This part meets all electrical and mechanical requirements with base product number B320. It maintains the same operating temperature range, RoHS3 compliance, and MSL rating. Inventory availability is significantly higher (32400 pcs), supporting high-volume production requirements.

All parts carry Active product status, ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected designation, confirming suitability for current and future production environments.

Frequently Asked Questions (FAQ)

Q: Can SS32-E3/57T replace SS32-M3/9AT in production?

A: Yes. Both parts are parametric equivalents with identical electrical specifications. The difference is packaging format: SS32-E3/57T uses Cut Tape & Digi-Reel while SS32-M3/9AT uses Tape & Reel. This affects handling and dispensing methods but not electrical performance or PCB compatibility.

Q: What is the difference between Vishay and Diodes Incorporated versions?

A: The B320-13-F from Diodes Incorporated meets all electrical and mechanical specifications of the Vishay SS32 series. Both manufacturers provide ROHS3-compliant, MSL Level 1 components in identical DO-214AB (SMC) packages. The primary difference is manufacturer identity and inventory availability.

Q: Are all these parts suitable for -55°C to 125°C operating range?

A: Yes. All four parts specify operating junction temperature range of -55°C to 125°C, confirming compatibility with extended temperature applications.

Q: Does packaging format affect PCB assembly compatibility?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel packaging formats contain identical components in the same DO-214AB (SMC) case. The packaging format affects only the supply method and handling during assembly; it does not alter electrical performance, thermal characteristics, or PCB footprint requirements.

Q: Which part should be selected for highest inventory availability?

A: B320-13-F from Diodes Incorporated provides the highest inventory level at 32400 pcs. For Vishay-specific sourcing, SS32-E3/9AT offers 3800 pcs in Tape & Reel format.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts carry ROHS3 Compliant status and REACH Unaffected designation, confirming compliance with current environmental and regulatory requirements.
