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 Teccor's broad line of thyristors. Teccor's 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 triggered from a blocking to conduction state for either polarity of applied AC voltage with operating modes in Quadrants I, II, and III. All alternistors have glass-passivated junctions to ensure longterm reliability and parameter stability. Teccor's glass-passivated junctions offer a reliable barrier against junction contamination. Teccor's TO-218X package is designed for heavy, steady powerhandling capability. All the isolated packages have a standard isolation voltage rating of 2500 V rms. Variations of devices covered in this data sheet are available for custom design applications.
