Data Sheet January 2000
30A, 200V Ultrafast Dual Diode
The RURH3020CC is an ultrafast dual diode (trr< 45ns)
with soft recovery characteristics. It has a low forward
voltage drop and is of planar, silicon nitride passivated,
ion-implanted, epitaxial construction.
This device is intended for use as an energy steering/
clamping diode and rectifier in a variety of switching power
supplies and other power switching applications. Its low
stored charge and ultrafast recovery with soft recovery
characteristics minimize ringing and electrical noise in many
power switching circuits thus reducing power loss in the
switching transistor.
Formerly developmental type TA09645.

DEFINITIONS
VF = Instantaneous forward voltage (pw = 300µs, D = 2%).
IR = Instantaneous reverse current.
trr = Reverse recovery time at dIF/dt = 100A/µs (See Figure 6), summation of ta + tb.
ta = Time to reach peak reverse current at dIF/dt = 100A/µs (See Figure 6).
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 6).
R
= Thermal resistance junction to case.
θJC
pw = pulse width.
D = duty cycle.
