Product overview

Description

The ACST10 series belongs to the ACS™/ACST power switch family built with A.S.D.(application specific discrete) technology. This high performance device is suited to home appliances or industrial systems, and drives loads up to 10 A.

This ACST10 switch has a Triac structure and a high voltage clamping device to absorb the inductive turn-off energy and withstand transients such as those described in the IEC 61000-4-5 standard. The ACST1010-7 needs a low gate current to be activated (I_GT< 10 mA) and still shows a high noise immunity complying with IEC 61000-4-4 standard. The ACST1035-7 offers a high static dV/dt immunity of 2 kV/μs minimum.

All features
Triac with overvoltage crowbar protection

Low I_GT (< 10 mA) or high immunity (I_GT< 35 mA) version

High noise immunity: static dV/dt > 2000 V/μs

Provides UL certified insulation rated at 2000 V_RMS
