General Description

Teccor offers bidirectional alternistors with current ratings from 6 A to 40 A and voltages from 200 V to 1000 V as part of Teccors broad line of thyristors. Teccors alternistor is specifically designed for applications that switch highly inductive loads. A special chip offers the same performance as two thyristors (SCRs) wired inverse parallel (back-to-back), providing better turn-off behavior than a standard triac. An alternistor may be trig gered from a blocking to conduction state for either polarity of applied AC voltage with operating modes in Quadrants I, II,and III.

Features

• Glass-passivated junctions

• 2500 V ac isolation for L, J, and K Packages

• High commutating dv/dt

• High static dv/dt

Q4008VH4属于分立半导体产品 > 晶闸管 - TRIAC。力特公司制造生产的Q4008VH4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。
