1 TURBOSWITCH TM ULTRA-FAST HIGH VOLTAGE DIODE MAIN PRODUCT CHARACTERISTICS IF(AV) VRRM rr (yp) VF (max) FEATURES AND BENEFITS 3 A 1200 V 65 ns 1.7 V SPECIFIC TO THE FOLLOWING OPERATIONS : SNUBBING OR CLAMPING, DEMAGNETIZA- TION AND RECTIFICATION ULTRA-FAST, SOFT RECOVERY VERY LOW OVERALL POWER LOSSES AND PARTICULARY LOW FORWARD VOLTAGE HIGH FREQUENCY OPERATION HIGH REVERSE VOLTAGE CAPABILITY DESCRIPTION TURBOSWITCH 1200V drasically cus losses in all high volage operaions which require exremely fas, sof and noise-free power diodes. Due o heir opimized swiching performances hey also highly decrease power losses in any associaed swiching IGBT or MOSFET in all "freewheel mode" operaions. K DPAK NC They are paricularly suiable in moor conrol circuiries, or in primary of SMPS as snubber, clamping or demagneizing diodes. They are also suiable for he secondary of SMPS as high volage recifier diodes.
