Engineering Selection Recommendations

Both substitute parts VS-12TTS08STRR-M3 and VS-12TTS08STRL-M3 are currently active products from Vishay General Semiconductor - Diodes Division, providing supply continuity for applications previously using the discontinued VS-12TTS08STRRPBF.

The substitute parts demonstrate improved performance characteristics in two parameters: off-state leakage current increases from 50µA to 1mA, and non-repetitive surge current capability increases from 95A to 110A at 50Hz. These variations remain within acceptable engineering tolerances for standard recovery SCR applications and do not restrict functional compatibility.

Both substitute parts maintain full ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The shift from bulk packaging to Tape & Reel format in the substitute parts reflects current industry supply chain practices and provides advantages for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can VS-12TTS08STRR-M3 and VS-12TTS08STRL-M3 be used interchangeably with VS-12TTS08STRRPBF?

A: Yes. Both substitute parts maintain identical voltage ratings (800V), current ratings (12.5A RMS), gate trigger characteristics (1V, 15mA), and on-state performance (1.2V, 8A average). The TO-263AB package pinout is identical, enabling direct board-level replacement without circuit modification.

Q: What is the difference between the two substitute parts?

A: VS-12TTS08STRR-M3 and VS-12TTS08STRL-M3 are parametrically equivalent. Both are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications and packaging. The part number suffix variation reflects internal manufacturing or supply chain designation but does not indicate functional differences.

Q: Are there differences in off-state leakage current between the main part and substitutes?

A: The main part specifies 50µA maximum off-state current, while both substitutes specify 1mA maximum. This represents a relaxation of the specification in the substitute parts. For applications sensitive to leakage current, this parameter difference should be evaluated against circuit requirements.

Q: Do the substitute parts have higher surge current capability?

A: Yes. The main part specifies 95A non-repetitive surge current at 50Hz, while both substitutes specify 110A. This represents improved surge handling capability and does not restrict compatibility with existing circuit designs.

Q: What packaging differences exist between the main part and substitutes?

A: The main part is supplied in bulk packaging, while both substitute parts are supplied in Tape & Reel (TR) format. Both use identical TO-263AB (D2PAK) component packaging with the same pinout and mechanical dimensions. The supply format difference affects handling and assembly processes but not electrical or mechanical compatibility.

Q: Are compliance certifications identical across all three parts?

A: Yes. All three parts are ROHS3 compliant, carry MSL Level 1 rating, and are REACH unaffected. Compliance certifications are equivalent across the main part and both substitutes.
