Overview

The ACS108-6SN-TR is a logic-level AC switch (ACS) specifically designed to drive low-power AC loads up to 800 mA. It integrates an overvoltage crowbar technology that eliminates the need for external snubbers or varistors, providing high noise immunity against dV/dt transients and IEC 61000-4-4 bursts.

Why Choose This Part

This device features a highly sensitive gate (10 mA max Igt) allowing direct interfacing with 3.3V or 5V microcontrollers. Its integrated VCL clamping prevents damage from voltage surges without requiring a separate MOV, significantly reducing total component count and PCB footprint in cost-sensitive designs.

Applications

Home Appliances
Driving small motors, fans, and valves in washing machines or dishwashers.
Heating Control
Switching low-power heating elements or actuators in HVAC systems.
Lighting Control
Managing solid-state relays or small AC lamps in automated building systems.
Solenoid Drivers
Directly controlling AC solenoids and actuators from a microcontroller GPIO.

Getting Started

Ensure the SOT-223 package tab is properly connected to the common terminal for thermal dissipation. When interfacing with a microcontroller, verify the GPIO can sink or source the required 10 mA gate trigger current, and use a series resistor to limit gate current within the 1V Vgt limit.

Also Consider

Z0103MN STMicroelectronics - Standard 1A logic level TRIAC for general AC switching where integrated crowbar protection is not required.
