T XDV 412 ---> 812 ALTERNISTORS . . . FEATURES VERY HIGH COMMUTATION : > 42.5 A/ms (400Hz) INSULATING VOLTAGE = 2500V(RMS) (UL RECOGNIZED : E81734) dV/dt : 500 V/µs min DESCRIPTION The TXDV 412 ---> 812 use a high performance passivated glass alternistor technology. Featuring very high commutation levels and high surge current capability, this family is well adapted to power control on inductive load (motor, transformer...)
