6A, 200V Ultrafast Dual Diodes
The RURD620CC and RURD620CCS are ultrafast dual diodes with soft recovery characteristics (trr < 25ns). They have low forward voltage drop and are silicon nitride passivated ion-implanted 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 soft recovery minimize ringing and electrical noise in many power switching circuits, thus reducing power loss in the switching transistors.
Formerly developmental type TA49037.

DEFINITIONS
VF = Instantaneous forward voltage (pw = 300µs, D = 2%). IR = Instantaneous reverse current. trr = Reverse recovery time (See Figure 9), summation of ta + tb. ta = Time to reach peak reverse current (See Figure 9). 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 9). QRR = Reverse recovery charge. CJ = Junction Capacitance. RθJC = Thermal resistance junction to case. pw = Pulse width.
D = Duty cycle.
