STMicroelectronics ACST2-8SB is a single, logic-sensitive gate TRIAC designed for AC power switching applications. This component offers an 800V off-state voltage and a 2A RMS on-state current capability. The sensitive gate configuration requires a maximum gate trigger current (Igt) of 10mA and a gate trigger voltage (Vgt) of 1.1V, facilitating control with low-power microcontrollers. With a hold current (Ih) of 10mA, it ensures reliable commutation. The ACST2-8SB features a surge current rating of 8A and 8.4A at 50Hz and 60Hz, respectively. Packaged in a TO-252-3, DPAK (2 Leads + Tab), SC-63 surface-mount case, it is suitable for automated assembly. Operating across a junction temperature range of -40°C to 125°C, this TRIAC finds application in lighting controls, motor control, and power supply units.
