Littelfuse Inc. Q4012LH5 is a snubberless TRIAC Alternistor designed for AC power control applications. This single-phase device features a 400V off-state voltage and a 12A RMS on-state current rating. The Q4012LH5 offers a maximum gate trigger current (Igt) of 50mA and a maximum holding current (Ih) of 50mA, with a gate trigger voltage (Vgt) of 1.3V. Its robust construction includes a non-repetitive surge current capability of 110A and 120A at 50Hz and 60Hz respectively. The component is housed in a TO-220 Isolated Tab package, facilitating through-hole mounting. Operating within a temperature range of -40°C to 125°C (TJ), this TRIAC is suitable for use in industrial power control, motor speed regulation, and lighting control systems.
