STMicroelectronics ACST12-7ST is a single, sensitive gate TRIAC designed for high-power AC control applications. This component features a maximum on-state current of 12 A (RMS) and an off-state voltage of 700 V. The sensitive gate triggering characteristics are defined by a maximum gate trigger current (Igt) of 10 mA and a maximum gate trigger voltage (Vgt) of 1 V, facilitating control with low-power logic devices. With a high surge current capability of 120 A and 126 A at 50/60 Hz, it ensures robust performance under transient conditions. The device operates within a temperature range of -40°C to 125°C (TJ) and is housed in a standard TO-220-3 through-hole package, suitable for mounting in various power control systems. Applications include motor control, lighting dimming, and general AC power switching across industrial and consumer electronics sectors.
