RHRU75120 Data Sheet April 1995 File Number 3408.2 75A, 1200V Hyperfast Diode Features The RHRU75120 (TA49042) is a hyperfast diode with soft recovery characteristics (tRR < 85ns). It has half the recovery time of ultrafast diodes and is silicon nitride passivated ion-implanted epitaxial planar construction. • Hyperfast with Soft Recovery . . . . . . . . . . . . . . . .<85ns This device is intended for use as a freewheeling/clamping diode and rectifier in a variety of high frequency switching power supplies and other power switching applications. Its low stored charge and hyperfast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors. • Avalanche Energy Rated PACKAGE TO-218 • Planar Construction Applications • Switching Power Supplies • General Purpose PACKAGING AVAILABILITY RHRU75120 • Reverse Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . .1200V • Power Switching Circuits Ordering Information PART NUMBER • Operating Temperature . . . . . . . . . . . . . . . . . . . +175oC BRAND Package RHRU75120 JEDEC STYLE TO-218 NOTE: When ordering, use the entire part number.
