ACS302-6T3-TR

Overview

The ACS302-6T3-TR is a discontinued logic-level sensitive-gate triac manufactured by STMicroelectronics. It features a maximum RMS on-state current of 400 mA and a rated repetitive off-state voltage of 600 V. The device operates within a junction temperature range of -40°C to +125°C and is housed in a 20-SOIC surface-mount package with a width of 7.50 mm. Key electrical parameters include a maximum gate trigger voltage of 900 mV, a maximum gate trigger current of 5 mA, and a maximum holding current of 20 mA. Non-repetitive peak on-state currents are specified at 7.3 A for 50 Hz and 7.6 A for 60 Hz frequencies.

Feature Summary

Logic-level sensitive gate architecture enabling direct drive from microcontrollers
Integrated overvoltage protection with clamping and crowbar capabilities
High immunity to voltage transients reducing the need for external snubbers

Applications

Appliance actuators such as water valves and drain pumps
Direct switching of resistive or inductive loads up to 250 W
Low-power appliance systems requiring high transient robustness

Procurement Notes

This component has been officially declared obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement parts. Designers should confirm that any substitute components meet the original electrical specifications and package dimensions to ensure compatibility with existing circuit layouts.

Selection Notes

Selection of this part requires consideration of its discontinued status. Engineers must evaluate alternative devices that offer equivalent 600 V blocking capability and 400 mA RMS current handling. Compatibility checks should focus on maintaining the logic-level gate sensitivity and ensuring the replacement package fits the 20-SOIC footprint constraints of the original design.

Part Context

The ACS302 belongs to the ACS series of static-switch semiconductors designed for alternating current applications. This series is characterized by simple driving requirements and high inductive load switch-off capability. These devices are specifically targeted at appliance actuators where direct microcontroller interface and high transient immunity are critical for system reliability.
