Description
RURU8040, RURU8050 and RURU8060 (TA9886) are ultrafast diodes with soft recovery characteristics (tRR < 75ns). They have low forward voltage drop and are silicon nitride passivated ionimplanted epitaxial planar construction.
These devices are intended for use as freewheeling/clamping diodes and rectifiers in a variety of switching power supplies and other power switching applications. Their low stored charge and ultrafast recovery with soft recovery characteristic minimizes 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.
