Rectifier Diode ASDS150KR40A AS ENERGITM in stud design, is a replacement, analogue, alternative and equivalent semiconductor device for normal recovery diode VS-150KR40A Vishay Semiconductors.
Average forward current IFAV – 150 ampere, repetitive peak reverse voltage VRRM – 400V. "Air-cooled heatsinks O series for stud devices" for diode cooling are also available to order.
Air and water heat sinks are used to cool the diodes. To provide reliable thermal and electrical contact with the heatsink a tightening torque Md must be observed during assembly. For better heat dissipation of diode during assembly, heat conducting paste is used (this is a recommendation and is not a prerequisite for installation).
Features of Standard Recovery Diodes: optimised for line frequency; low on-state losses; high reverse voltage and high current handling capabilities; press pack standard ceramic housing; designed for high power industrial and power transmission applications. Their main applications are rectifiers for large AC drives, aluminum smelting and other metal refining as well as trackside supply.
Rectifier Diodes AS ENERGITM have the following features: industry standard housing; low static and dynamic losses, high values of VRRM/VRSM, 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.
The technical specifications and parameters of VS-150KR40A and replacement ASDS150KR40A, datasheet PDF, outline drawing and dimensions are listed below.
Our company provides a quality guarantee for diodes of 2 years from the date of purchase. When supplying diodes, if necessary, we provide technical passport and certificate of conformity.
The final price for standard recovery diodes in stud design depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
