Description
The RHRU100120 (TA49070) is a hyperfast diode with soft recovery characteristics (tRR < 90ns). It has half the recovery time of ultrafast diodes and is silicon nitride passivated ionimplanted 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 power switching applications. Its low stored charge and hyperfast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors.

DEFINITIONS
VF = Instantaneous forward voltage (pw = 300μs, D = 2%).
IR = Instantaneous reverse current.
tRR = Reverse recovery time (See Figure 2), summation of tA + tB. tA = Time to reach peak reverse current (See Figure 2).
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 2).
RθJC = Thermal resistance junction to case.
EAVL = Controlled avalanche energy (See Figures 7 and 8). pw = pulse width.
D = duty cycle.
