T4050-6PF ST TRIACs

The T4050-6PF is a 40A standard Triac from STMicroelectronics in TO-3P through-hole package, featuring 600V repetitive peak off-state voltage and high surge current capability for high-power AC load switching. For selection, verify gate trigger current, non-repetitive surge current capability, low thermal resistance for high current operation, and operating junction temperature from -40°C to +125°C. Features include high current handling for heavy-duty industrial loads, through-hole TO-3P package for robust mounting, and planar technology for high reliability. Ideal for AC load switching in heavy-duty industrial equipment (motor starters, heating control), static relays, light dimmers for high power, induction motor starting circuits, and any 40A phase angle control application requiring 600V voltage rating for high-power AC loads.
