RURG30120
Data Sheet January 2000
30A, 1200V Ultrafast Diode
The RURG30120 is an ultrafast diode with soft recovery
characteristic (t
< 110ns). 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 characteristics
minimize ringing and electrical noise in many power
switching circuits, reducing power loss in the switching
transistors.
Formally developmental type TA49031.

DEFINITIONS
VF = Instantaneous forward voltage (pw = 300µs, D = 2%).
IR = Instantaneous reverse current.
trr = Reverse recovery time (See Figure 6), 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.
