BTA425X-800B中文资料3-Quadrant Triacs数据手册WeEn规格书

描述 Description

Planar passivated high commutation three quadrant triac in a SOT186A (TO-220F) \"full pack\" plastic package intended for use in circuits where high static and dynamic dV/dt and high dI/dt can occur. This \"series B\" triac will commutate the full rated RMS current at the maximum rated junction temperature without the aid of a snubber.

特性 Features

• 3Q technology for improved noise immunity
• High immunity to false turn-on by dV/dt
• High minimum IGT for guaranteed immunity to gate noise
• High voltage capability
• Isolated mounting base package
• Least sensitive gate for highest noise immunity
• Planar passivated for voltage ruggedness and reliability
• Triggering in three quadrants only
• Very high commutation capability with maximum false trigger immunity

应用 Application

• Electronic thermostats
• Heating control
• High power motor control
• High power switching

简介

BTA425X-800B属于分立半导体产品的晶闸管-TRIAC。由制造生产的BTA425X-800B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。
