The ST ACST4-7C is an AC Power Switch belonging to the ACST4 Series, built around ASD™ technology. This high-performance device is suitable for home appliances and industrial systems, capable of driving loads up to 4 A. It integrates a Triac structure with a high-voltage clamping device to absorb inductive turn-off energy and withstand line transients, enabling equipment to meet IEC 61000-4-5 standards.
Key electrical specifications include a repetitive peak off-state voltage (VDRM/VRRM) of +/-700V and an RMS on-state current (IT(RMS)) of 4A in a DPAK package at 110°C. It offers a high surge current capability of 30A for 20ms. The device features a high noise immunity with a static dV/dt greater than 500V/µs.
Available in DPAK and TO-220FPAB packages, the ACST4-7C is designed for AC static switching applications. Its benefits include direct interface with microcontrollers and no need for external overvoltage protection, reducing the power component factor. Main applications include appliance control systems like spray pumps in dishwashers and fans in air conditioners.
Operating temperature ranges from -30°C to +125°C, with a storage temperature range of -40°C to +150°C. The device is available in surface mount (DPAK) and through-hole (TO-220FPAB) mounting types.
