The Microchip 1N6626US is a fast recovery rectifier diode classified as Fast Recovery =< 500ns, > 200mA (Io), with a reverse recovery time (trr) of 30 ns. This places it in the standard-speed class for switching power supplies and freewheeling circuits where recovery losses matter but ultrafast parts are not required. Rated for 220 V DC reverse voltage (Vr max) and 1.75 A average rectified current (Io), the diode handles moderate-voltage, moderate-current rectification in continuous conduction mode. Reverse leakage is 2 µA at 220 V, and junction capacitance is 40 pF at 10 V, 1 MHz — relevant for snubbing and high-frequency switching applications.
Supplied in a SQ-MELF, A package (supplier device package A-MELF), surface-mount. The MELF (Metal Electrode Leadless Face) cylindrical body is self-centering during reflow and offers good thermal cycling performance, but requires careful pick-and-place nozzle selection to avoid tombstoning. The Bulk packaging indicates loose-tube delivery, not tape-and-reel — confirm feeder compatibility for automated assembly.
