Description
RURG5040, RURG5050 and RURG5060 (TA9909) are ultrafast
diodes with soft recovery characteristics (tRR < 65ns). They have low
forward voltage drop 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 ultrafast recovery
with soft recovery characteristic minimizes 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 at dIF/dt = 100A/µs (See Figure 2), 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.
EAVL = Controlled avalanche energy (See Figures 7 and 8).
pw = pulse width.
D = duty cycle.
