Description
RHRG3040CC, RHRG3050CC and RHRG3060CC are hyper-
fast diodes with soft recovery characteristics (tRR < 40ns). They
have half the recovery time of ultrafast diodes and are silicon	Symbol
nitride passivated ion-implanted epitaxial planar construction.	Symbol

These devices are intended for use as freewheeling/clamping
diodes and rectiﬁers in a variety of switching power supplies			K
and other power switching applications. Their low stored			K
and other power switching applications. Their low stored
charge and hyperfast soft recovery minimize ringing and electri-
cal 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).

QRR = Reverse recovery charge.

CJ = Junction Capacitance.

RθJC = Thermal resistance junction to case.

EAVL = Controlled avalanche energy. (See Figures 10 and 11). pw = pulse width.

D = duty cycle.
