30 ns reverse recovery — what it buys the switching stage
Its 30 ns reverse recovery time places it in the ultrafast class, suited for continuous-conduction-mode boost PFC stages, output rectification in flyback converters, and snubber clamping where the recovery charge must stay low to limit ringing.
Conduction loss and thermal budget at 3 A
Forward voltage is 1.1 V maximum at 3 A per diode, which sets the conduction loss at 3.3 W per die at rated current.
Reverse leakage and blocking stability
Reverse leakage is 3 µA at the full 200 V blocking voltage — a low figure that confirms the planar-epitaxial die construction. Leakage doubles roughly every 10°C above 25°C, so at 125°C junction the leakage stays under 50 µA, well within the margin of a typical PFC controller's overvoltage protection threshold.
Through-hole TO-220-3 package with the common-cathode pinout: the centre pin is the cathode common, the outer pins are the two anodes. The tab is electrically common with the centre pin, so the heatsink pad must be isolated or the heatsink itself must float. The 0.100-inch pitch is standard for TO-220 footprints.
