T405-800B-TR ST TRIACs

The T405-800B-TR is a 4A standard Triac from STMicroelectronics in DPAK surface-mount package, featuring 800V repetitive peak off-state voltage and 4A RMS on-state current for AC load switching applications. For selection, verify gate trigger current for standard or logic-level versions, non-repetitive surge current capability, surface-mount DPAK package for automated assembly, and operating junction temperature from -40°C to +125°C. Features include sensitive gate for direct microcontroller interface, planar technology for high reliability, and surface-mount DPAK package for automated assembly. Ideal for AC load switching in home appliances (washing machines, microwave ovens, refrigerators), light dimmers, motor speed control for small motors (power tools, kitchen appliances), solenoid and valve control, solid-state relays, and any 4A switching application requiring direct logic-level drive with 800V voltage rating.
