P6SMB82A-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB82A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose transient protection applications. This surface-mount component operates across a wide temperature range (-65°C to 150°C) and is RoHS3 compliant. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different packaging or sourcing requirements while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB82A-M3/5B are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A to 5.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to -65°C minimum; 150°C maximum
• Unidirectional Channels: 1
• Type: Zener

All identified substitute parts maintain these core electrical specifications. Variations in packaging format (Tape & Box vs. Tape & Reel) and manufacturer do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

P6SMB82A-E3/52 (Vishay): This part is a direct equivalent to the main part number, differing only in packaging format (Tape & Reel instead of Tape & Box). Both are manufactured by Vishay and maintain identical electrical specifications and RoHS3 compliance. Selection is appropriate when Tape & Reel packaging is preferred for automated assembly processes.

SZP6SMB82AT3G (Littelfuse): This substitute maintains all critical electrical parameters and is AEC-Q101 qualified for automotive applications. It includes capacitance specification (260pF @ 1MHz) and is supplied in Tape & Reel format. RoHS3 compliance is confirmed. This part is suitable for applications requiring automotive-grade components or when Littelfuse sourcing is preferred.

P6SMB82A (Eaton): This manufacturer-recommended substitute from Eaton Electronics Division provides equivalent electrical performance with a marginally higher peak pulse current specification (5.4A vs. 5.3A), which remains within acceptable tolerance for circuit compatibility. The operating temperature minimum is -55°C (compared to -65°C for Vishay variants), which may be a limiting factor in extreme cold environments. RoHS compliance is confirmed. This part is suitable for general telecom applications and when Eaton sourcing is available.

Frequently Asked Questions (FAQ)

Q: Can I use P6SMB82A-E3/52 as a direct replacement for P6SMB82A-M3/5B?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications. The only difference is packaging format: P6SMB82A-M3/5B uses Tape & Box, while P6SMB82A-E3/52 uses Tape & Reel. Electrical performance and circuit compatibility are unchanged.

Q: What is the difference between the Littelfuse SZP6SMB82AT3G and the Vishay variants?

A: The Littelfuse part maintains all critical electrical parameters (voltage, current, power ratings) and operating temperature range. It includes AEC-Q101 automotive qualification and specifies capacitance at 1MHz. Functionally equivalent for circuit design purposes.

Q: Is the Eaton P6SMB82A suitable for applications requiring -65°C operation?

A: The Eaton variant specifies a minimum operating temperature of -55°C, not -65°C. If your application requires operation at -65°C, use Vishay variants (P6SMB82A-M3/5B or P6SMB82A-E3/52) instead.

Q: Do all substitute parts use the same DO-214AA SMB package?

A: Yes. All listed parts use the DO-214AA (SMB) surface-mount package, ensuring identical PCB footprint and assembly compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts are RoHS compliant (Vishay and Littelfuse are ROHS3 compliant; Eaton is RoHS compliant). All meet REACH requirements.

Q: What is the peak pulse current difference between P6SMB82A-M3/5B and the Eaton P6SMB82A?

A: P6SMB82A-M3/5B specifies 5.3A, while Eaton P6SMB82A specifies 5.4A. This 0.1A difference is within normal manufacturing tolerance and does not affect circuit compatibility or performance.
