Forward drop is 1.4 V at the full 1.2 A rating — at 1.2 A continuous the conduction loss is about 1.7 W, which the SQ-MELF's metal lid sinks to the board if the copper pad is adequate. Reverse leakage is only 500 nA at 660 V at room temperature — the spec is at 25 °C; expect leakage to rise with junction temperature, but the 150 °C max junction gives headroom for hot environments. ## Package and deployment context SQ-MELF A (also called A-MELF) is a hermetic surface-mount package — the ceramic body and metal end caps seal the die from moisture, so it suits high-reliability and military/aerospace boards where plastic packages are not accepted.","metaTitle":"Microchip 1N6622US/TR Fast Recovery Diode, 660V 1.2A","metaDescription":"1N6622US/TR fast recovery rectifier, 660V 1.2A, 30ns trr, SQ-MELF A.
