Littelfuse Inc. QK004V4 is a standard TRIAC designed for demanding applications. This component features a repetitive peak off-state voltage of 1 kV and an RMS on-state current of 4 A. With a holding current (Ih) of 30 mA maximum and a gate trigger current (Igt) of 25 mA maximum, it offers reliable switching characteristics. The non-repetitive surge current is specified at 46 A and 55 A for 50 Hz and 60 Hz respectively. Operating across a temperature range of -40°C to 125°C (TJ), the QK004V4 utilizes a TO-251-3 Short Leads, IPAK, or TO-251AA package for through-hole mounting. This TRIAC is suitable for various industrial control systems, power switching, and motor control applications.
