Key parametric – 600 V, 1.2 A, 45 ns trr
The 1N6622: Rated for 600 V reverse voltage and 1.2 A average rectified current, this standard fast recovery diode switches with a 45 ns reverse recovery time. The 45 ns trr means it recovers fast enough for moderate-frequency rectification and flyback clamping without the losses of a slower 200 ns part, though it is not a hyperfast device for 100+ kHz SMPS designs. Forward voltage is 1.4 V max at the full 1.2 A forward current, and reverse leakage is just 500 nA at the 600 V reverse rating.
Through-hole axial – board-fit and handling
Supplied in a through-hole axial package (A-PAK), the 1N6622 mounts into standard 0.025-inch or larger lead holes on a PCB or terminal strip. The bulk packaging means you get loose parts, not tape-and-reel — plan for hand-insertion or vibratory bowl feed if you are running automated assembly.
