Engineering Selection Recommendations

The VS-6ESH06-M3/86A from Vishay General Semiconductor is a direct functional equivalent to the discontinued TPMR6J. Both components share identical electrical specifications across voltage, current, and switching characteristics, with matching TO-277A surface mount packaging.

The Vishay substitute maintains active product status, ensuring ongoing availability and supply chain continuity. Both parts comply with RoHS3 and REACH regulatory requirements, with identical moisture sensitivity classifications. The Vishay device provides an extended lower operating temperature limit (-65°C versus -55°C), offering additional thermal margin in applications requiring operation at lower temperatures.

Selection of the VS-6ESH06-M3/86A eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing circuit designs specified for the TPMR6J.

Frequently Asked Questions (FAQ)

Q: Can the VS-6ESH06-M3/86A be used as a direct replacement for the TPMR6J without circuit modification?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters: 600V reverse voltage, 6A average rectified current, 1.8V forward voltage drop at 6A, 40ns reverse recovery time, and identical TO-277A surface mount packaging. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The TPMR6J is discontinued at DiGi Electronics. The VS-6ESH06-M3/86A provides functional equivalence with active product status and confirmed inventory availability.

Q: Are there differences in packaging between these parts?

A: No. Both the TPMR6J and VS-6ESH06-M3/86A use the TO-277A surface mount package (3-PowerDFN), ensuring identical PCB footprint and assembly compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are RoHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). Regulatory compliance is equivalent.

Q: Is there a difference in operating temperature range?

A: The Vishay VS-6ESH06-M3/86A operates from -65°C to 175°C, while the TPMR6J operates from -55°C to 175°C. The Vishay part provides a 10°C lower temperature margin, which is compatible with all applications designed for the original part.

Q: What is the difference in reverse leakage current?

A: The TPMR6J specifies 10µA reverse leakage at 600V, while the VS-6ESH06-M3/86A specifies 5µA at 600V. The Vishay part exhibits lower leakage, which is a performance advantage and does not affect substitution compatibility.

Q: Are the packaging formats different?

A: The TPMR6J is supplied in Cut Tape (CT) and Digi-Reel format, while the VS-6ESH06-M3/86A is supplied in Tape & Reel (TR) format. Both are standard surface mount packaging formats suitable for automated assembly.
