Description
RURG3070CC, RURG3080CC, RURG3090CC and
RURG30100CC are ultrafast dual diodes with soft recovery
characteristics (tRR < 110ns). They have low forward voltage
drop and are silicon nitride passivated ion-implanted epitaxial
planar construction.
These devices are intended for use as freewheel/clamping
diode 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
minimizes ringing and electrical noise in many power switch-
ing 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), at dIF/dt = 100A/µs summation of tA + tB.
tA = Time to reach peak reverse current at dIF/dt = 100A/µs (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.
pw = pulse width.
D = duty cycle.
