RHRG30120
30A, 1200V Hyperfast Diode
The RHRG30120 is a hyperfast diode with soft recovery
characteristics (trr < 65ns). It has half the recovery time of
ultrafast diodes 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 high frequency switching
power supplies and other power switching applications. Its
low stored charge and hyperfast soft recovery minimize
ringing and electrical noise in many power switching circuits,
thus reducing power loss in the switching transistors.
Formerly developmental type TA49041.

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).
RθJC = Thermal resistance junction to case.
pw = pulse width.
D = duty cycle.
