Data Sheet January 2000
8A, 1200V Ultrafast Diode
The RURP8120 is an ultrafast diode with soft recovery
characteristics (t
< 100ns). It has low forward voltage drop
rr
and is of 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, thus reducing power
loss in the switching transistors.
Formerly developmental type TA49095.

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).
R
= Thermal resistance junction to case.
θJC
QRR = Reverse Recovery Charge.
CJ = Junction Capacitance.
pw = pulse width.
D = duty cycle.
