Description

Symbol

RHRG3070, RHRG3080, RHRG3090 and RHRG30100

(TA49064) are hyperfast diodes with soft recovery character-

istics (tRR < 65ns). 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/clamp-

ing diodes and rectiﬁers in a variety of switching power sup-

plies and other power switching applications. Their low

stored charge and hyperfast soft recovery minimize ringing

and electrical noise in many power switching circuits reduc-

ing power loss in the switching transistors.

DEFINITIONS

VF = Instantaneous forward voltage (pw = 300μs, D = 2%).

IR = Instantaneous reverse current.

tRR = Reverse recovery time (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.
