The Littelfuse Inc. QK012RH5 is a TRIAC Alternistor designed for high-power AC switching applications. This snubberless component offers a blocking voltage of 1 kV and a continuous on-state current of 12 A (RMS). It features a through-hole TO-220 package with a non-isolated tab for robust mounting and thermal management. The QK012RH5 exhibits a maximum gate trigger current (Igt) of 50 mA and a maximum holding current (Ih) of 50 mA, with a gate trigger voltage (Vgt) of 1.3 V (max). Its non-repetitive surge current capability is rated at 110 A and 120 A for 50 Hz and 60 Hz respectively. Operating across a temperature range of -40°C to 125°C (TJ), this TRIAC is suitable for use in industrial motor control, lighting control, and power switching circuits.
