Vishay Thyristor SCR, 800V, 35A, 150mA, TO-247 Package, Through Hole, VS-40TPS08-M3

The Vishay VS-40TPS08-M3 is a silicon-controlled rectifier (SCR) thyristor engineered for phase control in industrial and commercial systems. It combines robust electrical performance, reliability, and convenient mounting to support demanding power management tasks.

Equipped with a rated average on-state current (Irms) of 35A, this device is well suited for applications that require stable and continuous high current. With a repetitive peak reverse voltage (VDRM) of 800V, the VS-40TPS08-M3 safely operates in circuits with substantial voltage swings. Surge current capacity is rated at 600A, permitting it to withstand transient overloads and system spikes without permanent damage.

The maximum gate trigger current (Igt) of 150mA and a gate trigger voltage (Vgt) of 2.5V provide secure switching characteristics. The device features a through-hole TO-247 package, facilitating effortless integration into PCB layouts and assemblies. Its pin count of 3 and electrically isolated base plate contribute to safe operation and simplified mechanical installation.

Temperature tolerance ranges from -40°C to 125°C, making this thyristor suitable for operation across a wide variety of environments, including industrial, laboratory, and field applications. Holding current (Ih) is rated at 150mA, while repetitive peak off-state current remains low at 0.5mA, ensuring minimal leakage under standby conditions. Peak on-state voltage of 1.85V ensures efficient conduction during operation.

Designed specifically for phase control tasks, this SCR supports use in battery chargers, welding equipment, plating machinery, regulated power supplies, and temperature or speed control circuits. The device’s encapsulated and isolated base plate structure improves electrical safety and reliability while easing integration into industrial equipment.

This thyristor is synonymous with SCR technology, recognized for its bistable switching performance. Its precise triggering and robust construction make it an optimal component for engineers designing power regulation and control systems. The VS-40TPS08-M3 is not automotive-rated, but aligns with requirements for industrial electrical standards.
