Description
RURG1540CC, RURG1550CC and RURG1560CC
(TA9905) are ultrafast dual diodes with soft recovery char-
acteristics (tRR < 55ns). They have low forward voltage
drop and are silicon nitride passivated ion-implanted epi-
taxial 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 ultrafast recovery with soft recovery characteristic
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 7 and 8).
pw = pulse width.
D = duty cycle.
