Description
Symbol
RHRG5040, RHRG5050 and RHRG5060 (TA49065) are
hyperfast diodes with soft recovery characteristics (tRR
<45ns). 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 10 and 11).
pw = pulse width.
D = Duty cycle.
