The ACST1220H-8B belongs to the ACST power switch family. This high-performance device is suited to home appliances or industrial systems.

This high temperature 12 A AC 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.

Offering a low gate current triggering of only 20 mA, it benefits from ST Snubberless technology, enabling high level of noise immunity and turn-off commutation, the ACST1220H-8B eases PCB compliance with EMI standards such as IEC 61000-4-4 (fast transient burst test).

Package environmentally friendly ECOPACK2, RoHS (2011/65/EU) and halogen free compliant.

DPAK Package is UL-94, V0 flammability resin compliance and RoHS (2011/65/EU) compliant.
