ACS102-5TA-TR

Overview

The ACS102-5TA-TR is a discontinued AC line switch from STMicroelectronics, packaged in TO-92. It features a repetitive peak off-state voltage of 500 V and an RMS on-state current of 0.2 A at 100 °C ambient temperature. The device has a clamping voltage of 600 V and requires a maximum gate triggering current of 5 mA. Non-repetitive surge peak on-state current ratings are 7.3 A at 50 Hz and 8 A at 60 Hz. Operating junction temperature ranges from -30 °C to +125 °C.

Feature Summary

Integrates a high-voltage clamping structure to absorb inductive turn-off energy without external protection components.
Includes a gate level shifter driver that isolates the digital controller from the main switch.
Triggered by negative gate current flowing out of the gate pin for direct microcontroller interfacing.

Applications

AC on-off static switching in appliance control systems
Industrial control systems
Driving low power high inductive or resistive loads such as relays, valves, solenoids, dispensers, pumps, fans, micro-motors, door locks, and low power lamps

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Verify availability through authorized distributors or secondary market suppliers. Confirm lot dates and storage conditions carefully due to the discontinued status. Ensure compatibility with existing designs before sourcing replacements.

Selection Notes

Select this part for applications requiring integrated overvoltage protection and simplified gate drive circuits. The TO-92 package suits through-hole mounting. Consider thermal derating curves when designing for higher ambient temperatures. Verify load characteristics against the specified holding and latching currents.

Part Context

The ACS102-5TA-TR belongs to the ASD™ AC Switch family built around advanced semiconductor technology. It replaces traditional discrete triacs and snubber networks by integrating protection and logic interface functions into a single compact package, reducing overall component count significantly.
