For designs that see thermal cycling, high humidity, or vacuum environments, this package buys reliability that plastic-molded parts cannot match. With a reverse leakage of only 50 nA at 400 V, this diode suits high-impedance bias circuits or snubber networks where every nanoamp of leakage bleeds into the signal path. At 400 V the leakage is still negligible for most analog front-ends. Standard recovery speed (>500 ns) means it is not intended for high-frequency rectification or flyback clamping above a few kilohertz. Use it for 50/60 Hz line rectification, DC blocking, polarity protection, or freewheeling in low-speed inductive loads. The DO-213AA (MELF-style glass package) is surface-mount but requires attention to solder paste volume — the cylindrical body tends to roll during reflow if the pads are not symmetrical. A small solder dam or adhesive dot on the bottom side prevents tombstoning. Supplier device package is listed as DO-213AA; the base product number is 1N647, so this is the UR-1 suffix variant in a hermetic glass package rather than a plastic SOD or SOT alternative.","metaTitle":"Microchip 1N647UR-1 Standard Recovery Diode","metaDescription":"Active production 1N647UR-1 from Microchip Technology. 400V 400mA standard recovery rectifier in hermetic DO-213AA glass package.
