Applications
•Switching Power Supplies
•Power Switching Circuits
•General Purpose
Description
RHRU10040, RHRU10050 and RHRU10060 (TA49069) are hyperfast diodes with soft recovery characteristics (tRR < 50ns). They have half the recovery time of ultrafast diodes and are silicon nitride passivated ion-implanted epitaxial planar construction.
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 hyperfast soft recovery minimize ringing and electrical noise in many power switching circuits, reducing power loss in the switching transistors.

DEFINITIONS
VF = Instantaneous forward voltage (pw = 300μs, D = 2%).
IR = Instantaneous reverse current.
tRR = Reverse recovery time (See Figure 2), summation of tA + tB. tA = Time to reach peak reverse current (See Figure 2).
tB = Time from peak IRM to projected zero crossing of IRM based on a straight line from peak IRM through 25% of IRM (See Figure 2).
RθJC = Thermal resistance junction to case.
EAVL = Controlled avalanche energy (See Figures 7 and 8). pw = pulse width.
D = duty cycle.
