T405-700B-TR ST TRIACs

The T405-700B-TR is a 4A sensitive gate Triac with 700V repetitive peak off-state voltage in DPAK package. For selection, verify gate trigger current of 5mA to 10mA, on-state RMS current of 4A, peak surge current rating of 30A, and -40°C to +125°C operation. The sensitive gate allows direct drive from microcontrollers without high current buffers. Ideal for AC load switching, light dimmers, motor speed control, and solid-state relays in low-power applications. In stock at HL Electronics – request a quote for fast delivery.
