Product Description

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 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
•RoHS Compliant
• High surge current capability
• Glass-passivated junctions
• 2500 V ac isolation for L, J, and K Packages
• High commutating dv/dt
• High static dv/dt
