Scrs datasheet and documents for VS-40TPS12-M3

VS-40TPS12-M3

Scrs Overview

The Vishay VS-40TPS12-M3 is a high voltage phase control silicon controlled rectifier (SCR) designed for medium power switching applications. It features a maximum average on-state current of 35 A and a repetitive peak off-state voltage of 1200 V. The device utilizes glass passivation technology to ensure reliable operation up to a maximum junction temperature of 125 °C. Key electrical characteristics include a maximum peak on-state voltage of 1.85 V at 110 A, a maximum non-repetitive surge current of 600 A, and a maximum gate trigger current of 150 mA at 25 °C. It is housed in a TO-247AC 3L through-hole package.

Scrs Procurement Notes

Verify the specific part number suffix against official documentation to confirm exact triggering characteristics. The 'M3' designation indicates halogen-free, RoHS-compliant construction with lead-free terminations. Confirm that the standard IGT selection aligns with the gate drive circuit requirements before procurement.

Scrs Selection Notes

Select this component when a single SCR configuration with a 1200 V blocking capability is required. Ensure the thermal management design accommodates the specified maximum junction temperature of 125 °C. Verify that the gate drive circuit can supply the necessary trigger current without exceeding the maximum peak gate power dissipation limits defined in the datasheet.

Scrs Part Context

This component belongs to the VS-40TPS...-M3 series of high voltage phase control SCRs from Vishay Semiconductors. The series offers various voltage ratings, including 800 V and 1200 V options. The VS-40TPS12-M3 represents the standard gate trigger current variant within the 1200 V rating category, distinct from the low IGT 'A' suffix version.
