ACTT12B-800CT中文资料AC Thyristor Triacs数据手册WeEn规格书

描述 Description

AC Thyristor Triac power switch in a SOT404 (D2PAK) surface mountable plastic package with self-protective clamping capabilities against low and high energy transients. This \"series CT\" triac will commutate the full RMS current at the maximum rated junction temperature (Tj(max)] = 150 °C) without the aid of a snubber. It is used in applications where \"high junction operating temperature capability\" is required.

特性 Features

• Clamping structure ensuring safe high over-voltage withstand capability
• High junction operating temperature capability
• Full cycle AC conduction
• Over-voltage withstand capability to IEC 61000-4-5
• Pin compatible with standard triacs
• Planar passivated for voltage ruggedness and reliability
• Protective self turn-on capability for high energy transients
• Safe clamping capability for low energy over-voltage transients
• Less sensitive gate for high noise immunity
• Surface mountable package
• Triggering in three quadrants only
• Very high immunity to false turn-on by dV/dt

应用 Application

• AC fan, pump and compressor controls
• Highly inductive, resistive and safety loads
• Large and small appliances (White Goods)
• Reversing induction motor controls
• Applications subject to high temperature

简介

ACTT12B-800CT属于分立半导体产品的晶闸管-TRIAC。由制造生产的ACTT12B-800CT晶闸管 - TRIAC晶闸管可沿一个方向或在半个 AC 周期内传导 AC（交流电）。当 TRIAC（三极管 AC）的门极被触发时，即会沿任一方向传导电流。其他名称包括双向三极晶闸管或双侧三极晶闸管。TRIAC 分为无缓冲器、Alternistor、内部触发、逻辑门和标准型，安装方式包括底座、表面或通孔安装。这些器件可根据断态电压、通态电流、保持电流和门极触发电压进行选择。
