STMicroelectronics ACST4-7SB is a standard TRIAC designed for robust AC power control applications. This single-phase TRIAC offers a 700V off-state voltage and a 4A RMS on-state current handling capability. Featuring a DPAK (TO-252-3) surface-mount package, it is suitable for high-density circuit designs. The ACST4-7SB exhibits a maximum gate trigger current (Igt) of 25mA and a maximum hold current (Ih) of 35mA, with a gate trigger voltage (Vgt) of 1.1V. It also provides a non-repetitive surge current capability of 30A/33A at 50Hz/60Hz. Operating across a temperature range of -30°C to 125°C (TJ), this component finds application in motor control, lighting control, and power switching circuits within the appliance, industrial, and automotive sectors.
