Data Sheet January 2000
4A, 1200V Ultrafast Dual Diode
The RURP4120CC is an ultrafast dual diode with soft
recovery characteristics (t
< 70ns). It has low forward
rr
voltage drop and is silicon nitride passivated ion-implanted
epitaxial planar construction.
This device is intended for use as a freewheeling/clamping
diode and rectifier in a variety of switching power supplies
and other powerswitchingapplications.Itslow stored charge
and ultrafast soft recovery minimize ringing and electrical
noise in many power switching circuits reducing power loss
in the switching transistors.
Formerly developmental type TA49036.

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.
R
= Thermal resistance junction to case.
θJC
pw = Pulse width.
D = Duty cycle.
