They have low forward voltage drop and are silicon nitride passivated ion-implanted epitaxial planar construction. A 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.

IR = Instantaneous reverse current. tRR = Reverse recovery time at dIF/dt = 100A/s (See Figure 2), summation of tA + tB. tA = Time to reach peak reverse current at dIF/dt = 100A/s (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). RJC = Thermal resistance junction to case. EAVL = Controlled avalanche energy (See Figures 7 and 8). pw = pulse width. D = duty cycle.
