Fast Switching Thyristors IXYS WESTCODE Replacement
Fast Switching Thyristors, also known as Fast Turn Off Thyristors, ensure low switching losses and high di/dt performance.
Fast switching thyristors are suitable for existing inverter, DC chopper drives, UPS and pulse power applications.
Thyristors ATDP JY ENERGITM are a replacement, analog, alternative for Fast Switching Thyristors IXYS UK Westcode, Littelfuse Technology, formerly Westcode Semiconductors.
Fast Switching Thyristors (fast turn-off capsule type thyristors) are available from 400V up to 1200V, current from 295A up to 1007A and turn-off time tq from 10μs up to 30μs. The thyristor has an industry standard ceramic housing making it easy to integrate the device into existing equipment. This thyristor has a disc housing with pressure contacts.
The polarity of the thyristor is determined by the icon on the case. The technical specifications, part numbering guide, datasheets PDF, outline drawings for thyristors are listed below.
Thyristors JY ENERGITM have the following features: low static and dynamic losses, high values of VDRM/VRRM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 10 to 15000 A, high resistance to thermal and electric cycling, natural or forced air cooling.
Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport and certificate of conformity.
The final price of fast switching thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
