Description

RHRG1570CC, RHRG1580CC, RHRG1590CC and RHRG15100CC (TA49062) are hyperfast dual diodes with soft recovery characteristics (tRR < 60ns). They have half the recovery time of ultrafast diodes and are silicon nitride passivated ionimplanted 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 (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.
