VS-16TTS08SPBF SCR 800V 16A Equivalent & Substitute Parts

Part Overview

The VS-16TTS08SPBF is a silicon-controlled rectifier (SCR) rated for 800V off-state voltage and 16A RMS on-state current in a surface mount TO-263AB (D2PAK) package. Manufactured by Vishay General Semiconductor - Diodes Division, this thyristor is designed for standard recovery applications requiring high voltage switching capability.

This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Direct manufacturer alternatives and parametric equivalents from both Vishay and alternative suppliers are available to maintain design continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the VS-16TTS08SPBF is determined by the following critical parameters:

Off-state voltage rating: 800V minimum
RMS on-state current rating: 16A minimum
Gate trigger voltage (Vgt): 2V maximum
Gate trigger current (Igt): 60mA maximum
On-state voltage drop (Vtm): 1.4V maximum
Hold current (Ih): 150mA maximum
Package compatibility: TO-263-3 / D2PAK surface mount
Operating temperature range: -40°C to 125°C minimum
SCR type: Standard Recovery

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Vishay): VS-16TTS08S-M3, VS-16TTS08STRL-M3, and VS-16TTS08STRR-M3 maintain identical electrical specifications with differences only in packaging format (tube, tape & reel configurations).

Parametric Equivalent (Alternative Manufacturer): S8016NTP from Littelfuse Inc. meets the core voltage and current requirements with minor variations in gate trigger parameters and hold current, maintaining functional compatibility within the TO-263 package family.

Engineering Selection Recommendations

Vishay Direct Equivalents (VS-16TTS08S-M3, VS-16TTS08STRL-M3, VS-16TTS08STRR-M3):

These parts are recommended as primary substitutes. They maintain identical electrical specifications to the discontinued VS-16TTS08SPBF and are currently in active production status. All three variants are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Selection between these three should be based on packaging requirements: VS-16TTS08S-M3 is supplied in tube packaging, while VS-16TTS08STRL-M3 and VS-16TTS08STRR-M3 are supplied in tape & reel format. The tape & reel variants offer higher non-repetitive surge current ratings (200A @ 50Hz versus 170A @ 50Hz), providing additional design margin.

Littelfuse S8016NTP (Teccor® Series):

This part qualifies as a parametric equivalent for applications where gate trigger requirements are less stringent. The S8016NTP features lower gate trigger voltage (1.5V versus 2V) and lower gate trigger current (30mA versus 60mA), which may reduce gate drive circuit complexity. However, the on-state voltage is slightly higher (1.6V versus 1.4V), and the hold current is significantly lower (40mA versus 150mA). This part is suitable for designs where the lower hold current does not compromise circuit stability. The S8016NTP is ROHS3 compliant and currently in active production.

All substitute parts maintain the same TO-263 / D2PAK surface mount package footprint and operating temperature range, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can VS-16TTS08S-M3 be used as a direct replacement for VS-16TTS08SPBF?

A: Yes. VS-16TTS08S-M3 is a direct manufacturer equivalent with identical electrical specifications. The only difference is packaging format (tube versus the original packaging). Both are ROHS3 compliant and rated for -40°C to 125°C operation.

Q: What is the difference between VS-16TTS08STRL-M3 and VS-16TTS08STRR-M3?

A: Both parts are electrically identical and supplied in tape & reel packaging. The designation difference reflects internal Vishay packaging configuration codes. Both offer 200A non-repetitive surge current rating and are suitable for automated assembly processes.

Q: Is S8016NTP compatible with the original VS-16TTS08SPBF design?

A: S8016NTP is a parametric equivalent suitable for most applications. It meets the 800V voltage and 16A current requirements. However, verify that your gate drive circuit can operate with the lower trigger voltage (1.5V) and current (30mA), and confirm that the lower hold current (40mA) does not affect circuit stability in your specific application.

Q: Are all substitute parts available in the same package?

A: All substitute parts use the TO-263-3 / D2PAK surface mount package, ensuring PCB footprint compatibility. Packaging format (tube, tape & reel) varies by part number but does not affect electrical performance or physical dimensions.

Q: What compliance certifications apply to these substitute parts?

A: All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is MSL 1 (unlimited) for all parts.

Q: Can I mix different substitute part numbers in the same production run?

A: Yes, all substitute parts meet the same electrical specifications and package requirements. However, verify with your procurement and quality processes that mixed sourcing is acceptable for your application.
