P6SMB62A-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB62A-M3/5B is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 53V reverse standoff voltage class with an 85V maximum clamping voltage and 7.1A peak pulse current rating. The device is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, manufacturing discontinuation, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB62A-M3/5B are classified based on strict electrical parameter matching within the 53V voltage class. The primary substitution criteria are:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Clamping (Max) @ Ipp: 85V
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

Parts meeting these core electrical and mechanical parameters are considered direct substitutes. Variations in packaging format (Tape & Box vs. Tape & Reel vs. Cut Tape), manufacturer, and minor differences in peak pulse current or power dissipation do not disqualify substitution eligibility when the voltage class and package remain identical.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain the critical 53V reverse standoff voltage and 85V clamping voltage specifications required for circuit protection in this voltage class. Selection among substitutes should be based on the following factors:

Packaging Format Compatibility: The P6SMB62A-M3/5B is supplied in Tape & Box format. The P6SMB62A-E3/52 is the direct equivalent from the same manufacturer in Tape & Reel format, offering identical electrical specifications and temperature range. This substitution requires only packaging line adjustment.

Enhanced Performance Option: The 1KSMB62A from Taiwan Semiconductor Corporation provides higher peak pulse current (11.8A) and power dissipation (1000W) while maintaining voltage class equivalence. This part is suitable when circuit design permits higher transient energy absorption. Operating temperature range extends to 175°C.

Alternative Manufacturer: The P6SMB62A from Thinking Electronics Industrial Co. provides equivalent voltage and power specifications with marginally lower peak pulse current (7.06A). This part is RoHS compliant and suitable for telecom applications.

All substitute parts are Active product status and comply with RoHS and REACH regulations. Selection should confirm mechanical fit within the PCB assembly process and verify thermal management requirements for the intended application.

Frequently Asked Questions (FAQ)

Q: Can P6SMB62A-E3/52 replace P6SMB62A-M3/5B directly?

A: Yes. Both parts are manufactured by Vishay, share identical electrical specifications (53V standoff, 85V clamp, 7.1A peak pulse), and use the same DO-214AA package. The only difference is packaging format (Tape & Reel vs. Tape & Box), which affects procurement and assembly logistics but not electrical performance.

Q: Is 1KSMB62A a suitable substitute?

A: Yes, with design consideration. The 1KSMB62A maintains the 53V/85V voltage class and DO-214AA package. It provides higher peak pulse current (11.8A vs. 7.1A) and power dissipation (1000W vs. 600W), making it suitable for applications requiring enhanced transient protection. Operating temperature range is wider (-55°C to 175°C). Verify that the circuit design accommodates the higher performance characteristics.

Q: What is the difference between P6SMB6.8A and P6SMB62A-M3/5B?

A: P6SMB6.8A is not a substitute. It operates in a different voltage class (5.8V standoff, 10.5V clamp) with significantly higher peak pulse current (60A). This part is designed for low-voltage transient suppression applications and is not compatible with 53V circuit protection requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry RoHS3 or RoHS compliance certification and are REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Box, Tape & Reel, and Cut Tape formats contain identical die and electrical characteristics. Format selection is determined by assembly equipment compatibility and procurement volume requirements.
