1100 V reverse, 1 A average, 60 ns trr
The 1N6625: Rated for 1100 V DC reverse voltage and 1 A average rectified current, with a 60 ns reverse recovery time — the fast recovery speed (≤500 ns, >200 mA) suits snubber, flyback, and boost-diode positions in offline power supplies where the switching node sees high voltage and the diode must turn off quickly to limit ringing.
Through-hole axial, wide junction temperature
The through-hole axial package (DO-204AL equivalent) is a standard leaded format — it inserts into a plated through-hole on a single-sided or double-sided PCB and is wave-soldered.
Leakage and forward drop at rated conditions
Reverse leakage is 1 µA at 1100 V — negligible for a high-voltage rectifier in a low-duty-cycle snubber. Forward voltage is 1.75 V maximum at 1 A, which sets the conduction loss at about 1.75 W at full rated current; a heatsink or adequate copper pad on the anode lead is needed for continuous operation above 0.5 A.
Low capacitance for fast switching
With 10 pF typical capacitance at 10 V reverse bias and 1 MHz, the 1N6625 adds minimal capacitive loading to the switching node — important for maintaining the 60 ns trr in a high-frequency boost converter where the diode's own capacitance would otherwise slow the turn-off edge.
