ACST10 is Overvoltage protected AC switch manufactured by STMicroelectronics.
Overvoltage protected AC switch
G OUT
TO-220AB
G OUT
TO-220FPAB
Features
- Triac with overvoltage crowbar protection
- Low IGT (< 10 m A) or high immunity
(IGT < 35 m A) version
- High noise immunity: static d V/dt > 2000 V/µs
- Provides UL certified insulation rated at
2000 VRMS
Benefits
- Enables equipment to meet IEC 61000-4-5
- High off-state reliability with planar technology
- Need no external overvoltage protection
- Reduces the power passive ponent count
- High immunity against fast transients described in IEC 61000-4-4 standards
Applications
- AC mains static switching in appliance and industrial control systems
- Drive of medium power AC loads such as:
- Universal motor of washing machine drum
- pressor for fridge or air conditioner
- production data
Description
The ACST10 series 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 10 A.
This ACST10 switch has a Triac structure and a high voltage clamping device to absorb the inductive turn-off energy and withstand transients such as those described in the IEC 61000-4-5 standard. The ACST1010-7 needs a low gate current to be activated (IGT < 10 m A) and still shows a high noise immunity plying with IEC 61000-4-4 standard. The ACST1035-7 offers a high static d V/dt immunity of 2 k V/µs minimum.
