P6SMB400A-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB400A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 342V reverse standoff voltage range with a maximum clamping voltage of 548V at peak pulse current. The device is classified as Active product status and is designed for general purpose transient voltage suppression applications. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the DO-214AA (SMB) package family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB400A-M3/5B are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 342V
• Voltage - Breakdown (Min): 380V
• Voltage - Clamping (Max) @ Ipp: 548V
• Current - Peak Pulse (10/1000µs): 1.1A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1

All identified substitute parts maintain these core electrical specifications and package compatibility. Variations in operating temperature range, packaging format (Tape & Box vs. Cut Tape vs. Tape & Reel), and manufacturer do not affect functional equivalence for this application category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet RoHS compliance requirements. Selection between P6SMB400A-M3/5B, P6SMB400A (Eaton), and SMBJP6KE400A-TP is determined by packaging format availability and operating temperature requirements:

• P6SMB400A-M3/5B (Vishay): Tape & Box packaging; operating range -65°C to 150°C
• P6SMB400A (Eaton): Cut Tape and Digi-Reel packaging; operating range -55°C to 150°C
• SMBJP6KE400A-TP (Micro Commercial Co): Tape & Reel packaging; operating range -55°C to 175°C

All parts carry MSL 1 (Unlimited) moisture sensitivity classification and are REACH Unaffected or compliant. Component selection should be based on supply chain availability, packaging format compatibility with assembly processes, and thermal operating requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can P6SMB400A (Eaton) be used as a direct replacement for P6SMB400A-M3/5B (Vishay)?

A: Yes. Both parts share identical electrical specifications: 342V reverse standoff voltage, 380V minimum breakdown voltage, 548V maximum clamping voltage, 1.1A peak pulse current, and 600W peak pulse power. Both are packaged in DO-214AA (SMB) surface mount format. The primary difference is packaging format (Tape & Box vs. Cut Tape/Digi-Reel) and operating temperature range (-65°C to 150°C vs. -55°C to 150°C).

Q: Is SMBJP6KE400A-TP (Micro Commercial Co) compatible with the original P6SMB400A-M3/5B?

A: Yes. SMBJP6KE400A-TP maintains all critical electrical parameters and uses the same DO-214AA (SMB) package. The extended operating temperature range (-55°C to 175°C) provides additional thermal margin. Packaging format differs (Tape & Reel vs. Tape & Box).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching: Voltage - Reverse Standoff (342V), Voltage - Breakdown (380V minimum), Voltage - Clamping (548V maximum), Current - Peak Pulse (1.1A), Power - Peak Pulse (600W), Package / Case (DO-214AA, SMB), Mounting Type (Surface Mount), and Zener Type with single unidirectional channel.

Q: Does packaging format affect electrical performance?

A: No. Tape & Box, Cut Tape, Digi-Reel, and Tape & Reel formats are supply and assembly logistics variations only. Electrical performance and component specifications remain identical.

Q: Are there compliance or certification differences between these parts?

A: All three parts are Active status, RoHS compliant, REACH compliant or unaffected, and carry MSL 1 (Unlimited) moisture sensitivity. No functional compliance differences exist.
