Scrs Procurement Notes

Verify the specific voltage code suffix, as '12' indicates a 1200 V rating while '08' denotes 800 V. Confirm compliance requirements by checking for the '-M3' suffix, which signifies halogen-free and lead-free terminations compared to the standard PbF version. Ensure mounting torque specifications are strictly followed during installation to maintain thermal performance and mechanical integrity.

Scrs Selection Notes

Select this component based on the required blocking voltage level, choosing between 800 V or 1200 V ratings. Evaluate thermal management needs against the specified junction-to-case thermal resistance of 1.3 °C/W. Consider the gate triggering characteristics, specifically the DC gate current requirements which vary with junction temperature, to ensure compatibility with the drive circuitry.

Scrs Part Context

This part belongs to the VS-16TTS series of single SCR thyristors manufactured by Vishay Semiconductors. The series is designed for high voltage phase control applications using silicon technology. The TO-220AB package provides a standardized form factor suitable for through-hole mounting on heatsinks, facilitating efficient heat dissipation in medium power electronic designs.

Scrs Replacement Considerations

The VS-16TTS12-M3 serves as a direct replacement variant offering halogen-free compliance alongside lead-free terminations. Both versions share identical electrical ratings and physical dimensions, allowing for interchangeability without modifying the circuit layout or thermal interface design.

Scrs FAQ
