STMicroelectronics Surface Mount, 3-pin, TRIAC, 800V, Gate Trigger 1.1V

The ACST4 series belongs to the ACS / ACST power switch family. This high performance device is suited to home appliances or industrial systems and drives loads up to 4 A. This ACST4 switch embeds a Triac structure with a high voltage clamping device to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standards. The ACST410 needs a low gate current to be activated (IGT < 10 mA) and still shows a high electrical noise immunity.

Triac with overvoltage protection
Low IGT(< 10 mA) or high immunity(IGT < 35 mA) version
High noise immunity: static dV/dt > 1000 V/μs
TO-220FPAB insulated package:
insulation voltage: 2000 VRMS
