MUR820, RURP820 Data Sheet January 2000 File Number 1355.5 8A, 200V Ultrafast Diodes Features MUR820 and RURP820 are ultrafast diodes with soft recovery characteristics (trr < 25ns). They have low forward voltage drop and are silicon nitride passivated ion-implanted epitaxial planar construction. • Ultrafast with Soft Recovery . . . . . . . . . . . . . . . . . . . <25ns These devices are intended for use as freewheeling/ clamping diodes and rectifiers in a variety of switching power supplies and other power switching applications. Their low stored charge and ultrafast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors. • Avalanche Energy Rated • Reverse Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . .200V • Planar Construction Applications • Switching Power Supplies • Power Switching Circuits Formerly developmental type TA09223. • General Purpose Ordering Information PART NUMBER • Operating Temperature. . . . . . . . . . . . . . . . . . . . . . .175oC PACKAGE BRAND MUR820 TO-220AC MUR820 RURP820 TO-220AC RURP820 NOTE: When ordering, use the entire part number.
