ACST Series 800V AC Switches



STMicroelectronics ACST Series AC Switches

STMicroelectronics’ rugged alternative to conventional Triacs

STMicroelectronics' overvoltage protected AC switches devices are a rugged alternative to conventional Triacs for appliance and industrial applications. These AC switches embed a Triac structure and a high voltage clamping device that is able to absorb the inductive turn-off energy and withstand line transient voltages. This expanded series has VRRM range increased from 700V to 800V, spanning the current range from 4A to 6A.

  Features (versus standard Triacs)   Applications
  • Improved commutating dV/dt
  • Improved commutating dI/dt
  • Enable appliances to meet IEC 61000-4-4 and
    -4-5 standards
  • Overvoltage protection is built in
  • Sensitive gate option allows direct drive from microcontroller
  • Full range of packages:
    DPAK, D²PAK, TO-220, TO-220FP
  • Washing machine drum motor control
  • Refrigerator compressor control
  • Dishwasher pump motor control
  • Industrial systems-medium power loads
  • RoHS Compliant
