ACST Series 800 V AC Switches

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 700 V to 800 V, spanning the current range from 4 A to 16 A.

Features (Versus Standard Triacs)

• 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

Applications

• Washing machine drum motor control
• Refrigerator compressor control
• Dishwasher pump motor control
• Industrial systems-medium power loads
