January 2002
6A, 600V Hyperfast Diodes
The RHRD660 and RHRD660S are hyperfast diodes with
soft recovery characteristics (trr < 30ns). 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.
Formerly developmental type TA49057.

DEFINITIONS
VF = Instantaneous forward voltage (pw = 300µs, D = 2%).
IR = Instantaneous reverse current.
trr = Reverse recovery time (See Figure 9), summation of ta + tb.
ta = Time to reach peak reverse current (See Figure 9).
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 9).
QRR = Reverse recovery charge.
CJ = Junction capacitance.
RθJC = Thermal resistance junction to case.
pw = Pulse width.
D = Duty cycle.
