TURBOSWITCH ULTRA-FAST HIGH VOLTAGE DIODE

STMicroelectronics 

APPLICATION DATA

The 1200V TURBOSWITCH series has been

designed to provide the lowest overall power

losses in all high frequency or high pulsed current

operations. In such applications (Fig A to D),the

way of calculating the power losses is given below :
