ACST12 交流开关系列瞬态保护交流开关

The ACST12 series belongs to the ACS/ACST family built with the ASD (application specific discrete) technology. This high performance device is adapted to home appliances or industrial systems and drives loads up to 12 A.

This ACST12 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 standards. The ACST12-7S needs a low gate current to be activated (IGT < 10 mA) and in the mean time provides a high electrical noise immunity such as those described in the IEC 61000-4-4 standards. The ACST12-7C offers an extremely high static dV/dt immunity of 2 kV/μs minimum.

ACST12 产品特性:

• Features
  ■ Triac with overvoltage crowbar technology
  ■ Low IGT (<10 mA) or high immunity (IGT<35 mA) version
  ■ High noise immunity: static dV/dt > 2000 V/μs
• Benefits
  ■ Enables equipment to meet IEC 61000-4-5
  ■ High off-state reliability with planar technology
  ■ Need no external over voltage protection
  ■ Reduces the power passive component 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 like:
  – Universal drum motor of washing machine
  – Compressor for fridge or air conditioner
