That trr puts it squarely in the 100 kHz+ switching range — a PFC boost stage, a flyback snubber clamp, or a high-frequency output rectifier where a standard recovery diode would overheat from reverse recovery losses. The SQ-MELF (A-MELF) package is a hermetic glass body with metallized end caps — no plastic molding, no moisture ingress path. ## Parametric floor — what the numbers mean for the BOM line Forward voltage is 1.4 V max at the full 1.2 A rated current. At 1.2 A and 30 ns trr, the switching loss term (0.5 × Vf × If × trr × f) dominates at frequencies above 200 kHz — the diode's thermal limit in the SQ-MELF body is set by the sum of conduction and switching losses, not by the average current alone. Reverse leakage is 500 nA max at 220 V and 25°C, doubling roughly every 10°C. At 125°C junction the leakage is in the low microamp range — negligible for the rectifier's efficiency but relevant if the diode sits across a high-impedance node where leakage could pull a bias rail out of regulation. Junction capacitance is 10 pF at 10 V reverse bias. This is low enough that the capacitive switching loss (0.5 × Cj × Vr² × f) stays under 10 mW at 500 kHz, so the trr is the dominant switching parameter, not the junction charge. ## Active lifecycle — no LTB clock ticking The Tape & Reel packaging (TR suffix) is the standard surface-mount reel format. Volume quotes are confirmed against the BOM quantity at RFQ time; the part is sourced through authorized distribution with full traceability.","metaTitle":"Microchip 1N6620US/TR Fast Recovery Diode, 1.2 A, 220 V","metaDescription":"1N6620US/TR from Microchip Technology — 1.2 A, 220 V fast recovery diode, 30 ns trr, SQ-MELF surface mount.
