STMicroelectronics ACST4-7SB-TR is a standard TRIAC designed for AC power switching applications. This single-phase TRIAC offers a repetitive peak off-state voltage (VDRM) of 700V and an RMS on-state current (IT(RMS)) of 4A. It features a gate trigger current (IGT) of 25mA and a holding current (IH) of 35mA, ensuring reliable triggering characteristics. The non-repetitive surge current handling is 30A at 50Hz and 33A at 60Hz. Packaged in a TO-252-3, DPAK (SC-63) for surface mounting, this component operates within an ambient temperature range of -30°C to 125°C. The ACST4-7SB-TR is commonly utilized in home appliance control, lighting control, and industrial automation systems.
