Fast recovery diode for PFC and flyback secondaries
The 1N6628 is a 600 V, 1.75 A fast recovery rectifier diode from Microchip Technology, packaged in the through-hole A-PAK (axial-lead) format. The 2 µA reverse leakage at 600 V is low for a fast-recovery part, helping keep standby power draw minimal in offline supplies.
Active lifecycle — no end-of-life risk for existing BOMs
The through-hole A-PAK package is a legacy footprint still widely used in power-factor-correction stages and high-reliability power supplies where vibration resistance and field-replaceability are priorities.
Compliance documentation (RoHS, REACH) is provided by Microchip Technology per the standard datasheet and certificate of conformance. The part is not UL-recognized or AEC-Q101 qualified — it is a commercial/industrial-grade rectifier diode.
