ACST4：Overvoltage protected AC switch

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 (I_GT< 10 mA) and still shows a high electrical noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

Provides UL 1557 certified insulation rated at 2000 V rms.

Key Features

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 complies with UL 1557 standard (file ref: E81734)
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
