Product overview

Description

The ACST8 series belongs to the ACS/ACST power switch family built around A.S.D. (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems and drives an induction motor up to 8 A.

This ACST8 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.

ACST8 shows a high noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

All features
Triac with overvoltage protection

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

TO-220FPAB insulated package:

complies with UL standards (File ref : E81734)

insulation voltage: 2000 V_RMS

Benefits:

Enables equipment to meet IEC 61000-4-5

High off-state reliability with planar technology

Needs no external overvoltage protection

Reduces the power passive component count

High immunity against fast transients described in IEC 61000-4-4 standards
