Fast recovery switching — 30 ns trr at 1.3 A
The 1N6077/TR is a standard fast-recovery diode rated for 1.3 A average rectified current with a 100 V reverse voltage ceiling. Its 30 ns reverse recovery time (trr) places it well inside the Fast Recovery =< 500ns, > 200mA (Io) classification — meaning it handles the turn-off edge in switching supplies and snubber circuits without the stored charge tail of a general-purpose rectifier.
Thermal and leakage margins for the BOM
Junction temperature spans -65°C to 155°C — military/industrial grade that covers engine-bay and outdoor enclosure hot spots without derating the average current. Reverse leakage is 5 µA at 100 V, so the diode does not add a meaningful standing loss in a high-impedance bias circuit. Forward voltage is 1.76 V at 18.8 A pulsed — the spec matters for surge current handling, not continuous conduction.
Microchip Technology lists the 1N6077/TR as Active. The through-hole axial package (A, Axial) ships in Tape & Reel.
