T850-8G分立半导体产品的晶闸管-TRIAC规格书PDF中文资料

T850-8G属于分立半导体产品的晶闸管-TRIAC。由意法半导体集团制造生产的T850-8G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。

特性 Features

• On-state rms current, IT(RMS) 8 A

• Repetitive peak off-state voltage, VDRM / VRRM 600 V to 800 V

• Triggering gate current, IGT 5 to 50 mA

描述 Description

Available either in through-hole and surface-mount packages, these devices are

suitable for general purpose AC switching. They can be used as an ON/OFF function

in applications such as static relays, heating regulation, induction motor starting

circuits or for phase control operation in light dimmers and motor speed controllers,

etc.

The Snubberless versions (BTA, BTB08_xxxxW and T8 series) are specially

recommended for use on inductive loads, thanks to their high commutation

performance.

Logic level versions are designed to interface directly with low power drivers such as

Microcontrollers.

By using an internal ceramic pad, the BTA series provide voltage insulated tab (rated

at 2500 VRMS) in compliance with UL standards (file ref.: E81734).
