ACST310-8FP

Overvoltage protected AC switch

Datasheet

− production data

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 qualified resin (flammability)

• Complies with UL standards UL1557

– Insulated voltage: 2000 VRMS

• ECOPACK®2 compliant component

Benefits

• Enables equipment to meet IEC61000-4-5

• High immunity against fast transients

described in IEC61000-4-4 standard

• Needs no external overvoltage protection

• High off-state reliability power device

• Interfaces directly with the microcontroller

• Reduces component count

Applications

• AC static switching in appliances and industrial

control systems

• Driving low power highly inductive loads or

resistive AC loads, such as motor control

circuits, small home appliances, lighting, fan

speed controllers, water valves, pumps, solid

state relays, vacuum cleaners, heater

Description

The ACST310-8FP 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 ACST310-8FP switch embeds a Triac

structure and 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). It

provides UL certified insulation rated at 2000

VRMS (file ref: E81734).
