STMicroelectronics TRIAC, ACST4-7SH, is a standard TRIAC designed for AC power control applications. This component features a 700V off-state voltage and a 4A RMS on-state current rating, making it suitable for demanding power switching. With a maximum gate trigger current (Igt) of 25 mA and a gate trigger voltage (Vgt) of 1.1V, it offers reliable triggering characteristics. The TRIAC exhibits a hold current (Ih) of 35 mA and non-repetitive surge capabilities of 30A and 33A at 50Hz and 60Hz respectively. Housed in an IPAK package (TO-251-3 Long Leads, IPak, TO-251AB) for through-hole mounting, this device operates within a temperature range of -30°C to 125°C (TJ). It finds application in industrial automation, home appliances, and lighting control systems.
