P6SMB82A-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB82A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 70.1V reverse standoff voltage range with a 113V maximum clamping voltage and 5.3A peak pulse current rating. The device is designed for general purpose transient voltage suppression applications and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate different packaging or sourcing requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB82A-M3/52 is determined by strict equivalence across the following critical parameters:

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

Substitute parts must maintain identical voltage specifications and peak pulse current ratings within the specified range. Package compatibility (DO-214AA SMB) and surface mount capability are mandatory. Packaging format (Tape & Box vs. Tape & Reel) does not affect electrical or mechanical compatibility and represents a logistics variation only.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the P6SMB82A-M3/52 based on provided specifications.

P6SMB82A-E3/52 (Vishay): Direct equivalent from the same manufacturer. Identical electrical specifications and operating temperature range. Differs only in packaging format (Tape & Reel vs. Tape & Box). ROHS3 compliant. Suitable for direct substitution in all applications.

SZP6SMB82AT3G (Littelfuse): Cross-manufacturer equivalent with identical voltage and current specifications. Includes AEC-Q101 automotive qualification and 260pF capacitance specification at 1MHz. ROHS3 compliant. Suitable for direct substitution in all applications, including automotive-grade requirements.

P6SMB82A (Eaton): Manufacturer-recommended equivalent with marginally higher peak pulse current rating (5.4A vs. 5.3A), providing additional design margin. Operating temperature range is -55°C to 150°C (TJ), which is narrower at the lower end compared to the main part (-65°C minimum). ROHS3 compliant. Suitable for substitution in applications where the -55°C minimum temperature is acceptable.

Frequently Asked Questions (FAQ)

Q: Can P6SMB82A-E3/52 be used as a direct replacement for P6SMB82A-M3/52?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications, voltage ratings, current ratings, and operating temperature range. The only difference is packaging format (Tape & Reel vs. Tape & Box), which does not affect electrical or mechanical performance.

Q: What is the difference between the Littelfuse SZP6SMB82AT3G and the Vishay P6SMB82A-M3/52?

A: Electrical specifications are identical across voltage, current, and power ratings. The Littelfuse part includes AEC-Q101 automotive qualification and specifies capacitance at 1MHz (260pF). Both are RoHS3 compliant and operate across the same temperature range. The parts are cross-manufacturer equivalents suitable for direct substitution.

Q: Is the Eaton P6SMB82A suitable for all applications requiring the P6SMB82A-M3/52?

A: The Eaton part is suitable for applications where the operating temperature range of -55°C to 150°C (TJ) is acceptable. The main part specifies -65°C to 150°C (TJ). The Eaton part provides a slightly higher peak pulse current rating (5.4A vs. 5.3A), which offers additional design margin. Verify temperature requirements before selection.

Q: Does packaging format (Tape & Box vs. Tape & Reel) affect component performance?

A: No. Packaging format is a logistics and handling consideration only. It does not affect electrical performance, mechanical compatibility, or PCB assembly. Both formats contain identical components in the same DO-214AA SMB package.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS3 compliant or RoHS compliant, meeting environmental and regulatory requirements equivalent to the main part.

Q: Can these parts be used interchangeably in automotive applications?

A: The Littelfuse SZP6SMB82AT3G includes AEC-Q101 automotive qualification. The Vishay and Eaton parts do not specify automotive qualification in the provided data. Verify automotive requirements with component datasheets or manufacturer documentation before selection for automotive applications.
