SS32-M3/57T Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS32-M3/57T is an active Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 20 V DC reverse voltage with 3 A average rectified current capacity. The device is packaged in DO-214AB (SMC) format and is supplied on Tape & Reel (TR) media.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or when alternative packaging formats better suit manufacturing requirements. All substitute parts listed maintain identical electrical performance and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitution of the SS32-M3/57T is permissible when the replacement component meets all of the following criteria:

Critical Electrical Parameters (Must Match Exactly):

• 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
• Operating Temperature - Junction: -55°C to 125°C

Mechanical & Packaging Requirements (Must Match):

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance Requirements (Must Match):

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

Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) does not affect electrical or mechanical compatibility and may vary between substitute parts based on supply availability and manufacturing requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and MSL Level 1 rating, indicating full regulatory compliance and unlimited shelf life under standard storage conditions.

SS32-E3/57T (Vishay): This substitute maintains identical electrical specifications and mechanical packaging. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). This part is suitable for applications where alternative tape formats are acceptable. Inventory availability is 1262 units.

SS32-E3/9AT (Vishay): This substitute maintains identical electrical specifications and mechanical packaging in Tape & Reel format. This part is suitable for direct replacement in manufacturing processes requiring standard reel packaging. Inventory availability is 3800 units.

B320-13-F (Diodes Incorporated): This substitute is manufactured by Diodes Incorporated and maintains all critical electrical specifications and mechanical packaging requirements. The part is supplied on Tape & Reel format. Inventory availability is 32400 units. This cross-manufacturer substitute is suitable for applications where multi-source qualification is required or when Vishay supply is constrained.

Selection among these substitutes should be based on packaging format requirements, supply chain preferences, and manufacturing process compatibility. All parts are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can SS32-E3/57T replace SS32-M3/57T in my application?

A: Yes. Both parts are Schottky diodes with identical electrical ratings (20 V, 3 A, 500 mV forward voltage, fast recovery ≤ 500ns), the same DO-214AB SMC package, and equivalent compliance certifications. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Electrical and mechanical compatibility is complete.

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

A: Tape & Reel (TR) supplies components on continuous reel format suitable for automated pick-and-place equipment. Cut Tape (CT) supplies components on individual tape segments. Digi-Reel is a Vishay-specific format combining tape and reel characteristics. All three formats contain identical components; the difference is in supply presentation and handling during assembly.

Q: Can I use B320-13-F from Diodes Incorporated instead of the Vishay SS32 series?

A: Yes. The B320-13-F meets all critical electrical parameters (20 V reverse voltage, 3 A current, 500 mV forward voltage, fast recovery speed) and is packaged in the same DO-214AB SMC format. Both manufacturers' parts are ROHS3 compliant with MSL Level 1 rating. Cross-manufacturer substitution is permissible when all electrical and mechanical specifications align.

Q: Are there any temperature or compliance differences between these parts?

A: No. All listed parts operate across the identical temperature range (-55°C to 125°C junction temperature), carry ROHS3 compliance certification, and have MSL Level 1 rating. Regulatory and environmental performance is equivalent across all substitutes.

Q: What parameters must remain identical for substitution to be valid?

A: The following parameters must match exactly: Voltage - DC Reverse (20 V), Current - Average Rectified (3 A), Voltage - Forward (500 mV @ 3 A), Speed (Fast Recovery ≤ 500ns), Current - Reverse Leakage (500 µA @ 20 V), Package (DO-214AB SMC), Mounting Type (Surface Mount), Operating Temperature Range (-55°C to 125°C), and Compliance Status (ROHS3, MSL 1). Packaging format (reel type) does not affect substitution validity.

Q: Which substitute has the highest inventory availability?

A: B320-13-F from Diodes Incorporated has 32400 units in stock, compared to 3800 units for SS32-E3/9AT and 1262 units for SS32-E3/57T. Inventory levels should be verified with current suppliers as stock quantities change.
