Data Sheet January 2000

75A, 1200V Ultrafast Diode

The RURU75120 is an ultrafast diode with soft recovery
characteristics (t

< 125ns). It has low forward voltage drop

rr

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 recovery with soft recovery characteristic
minimize ringing and electrical noise in many power
switching circuits reducing power loss in the switching
transistors.

Formerly developmental type TA49032.

DEFINITIONS

VF = Instantaneous forward voltage (pw = 300µs, D = 2%).

IR = Instantaneous reverse current.
trr = Reverse recovery time summation of ta + tb.

ta = Time to reach peak reverse current (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.
