Fast Switching Thyristor

 

We supply various shapes of fast switching thyristor which is also called fast thyristor.It is a fast turn off thyristor.Our fast thyristor include standard fast switching thyristor and medium frequency fast thyristor.It’s current range from 500A to 4000A, voltage range from 1000V to 4500V.Tq value have 10-25us,30-50us and 50-70us.With excellent fast turn on-off performance,our fast thyristors are hot used on inverter circuit.For example induction heating,thyristor frequency converter,furnace power supply,inverter device etc.

 

Along with application of high frequency & medium frequency equipment,fast thyristors require lower tq values.We continuously optimize tq values of fast switching thyristor to meet client’s requirements.
