Product Introduction

Overview

The ACS120-7ST, produced by STMicroelectronics, is a high-performance AC line switch that belongs to the AC line switch family built around the ASD™ (Advanced Switching Device) concept. This component is designed to control loads up to 2 A and is known for its robust and reliable performance in various applications. It features an integrated driver and a high voltage clamping structure, making it suitable for use in environments with high inductive turn-off energy.

Key Features

  • Overvoltage protected AC switch with integrated driver.
  • No need for external protection snubber or varistor.
  • High noise immunity: static dV/dt > 500 V/µs.
  • Eliminates gate kickback on the microcontroller.
  • Reduces component count up to 80%.
  • Interfaces directly with the microcontroller.
  • Allows straightforward connection of several ACS™ switches on the same cooling pad.
  • Ecopack2 compliant and RoHS compliant.

Applications

  • AC static switching in appliance control systems.
  • Drive of low power high inductive or resistive loads such as relays, valves, solenoids, dispensers, pumps, fans, and micro-motors.
  • Defrost heaters.
