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)
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, heaters
Datasheet production data
Description
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 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).
