ACST4-7CB-TR

Overview

The ACST4-7CB-TR is a logic-sensitive gate triac from the ASD™ family, rated for 700 V repetitive peak off-state voltage and 4 A RMS on-state current. It features an integrated avalanche-controlled clamping device with a typical breakdown voltage of 1100 V to absorb inductive turn-off energy and withstand line transients per IEC 61000-4-5 standards. The component operates within a junction temperature range of -30 °C to +125 °C and utilizes a DPAK surface-mount package.

Feature Summary

ASD™ technology provides high off-state reliability through planar technology
Integrated overvoltage protection eliminates the need for external clamping components
Logic-level interface allows direct connection to microcontrollers without additional drive circuitry

Applications

AC static switching in home appliance control systems
Driving low-power high-inductive loads such as dishwasher spray pumps
Fan motor control in air-conditioning units

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the tape and reel packaging configuration. Ensure that the component designation matches the exact part number required for the intended application design.

Selection Notes

Select this variant when a 700 V blocking voltage and 4 A continuous current rating are required. The 'C' suffix indicates a higher gate trigger current threshold compared to the 'S' version, offering increased immunity to electrical noise while maintaining direct microcontroller compatibility.

Part Context

This component belongs to the ACST4 series of AC power switches designed by STMicroelectronics. The series utilizes ASD™ technology to provide robust performance in residential and industrial environments, specifically targeting applications requiring reliable switching of inductive or resistive loads up to 4 Amperes.
