  • The ACST310-8B 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 3 A.

    This ACST310-8B switch embeds a Triac structure with a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standard.The component needs a low gate current to be activated (IGT max. 10 mA) and still shows a high electrical noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

    Key Features

    • AC switch with self over voltage protection
    • Microcontroller direct driven (low gate current max. 10 mA)
    • Three quadrants (Q1, Q2 and Q3)
    • UL94-V0 certified resin (flammability)
    • ECOPACK®2 compliant component
