Its 50 ns reverse recovery time (trr) is the parameter that decides the switching-loss budget in flyback snubbers, PFC boost diodes, and secondary-side freewheeling paths where the recovery charge would otherwise hammer the MOSFET or controller. ## 400 V / 500 mA — where the envelope fits Rated 400 V reverse and 500 mA average forward, this diode sits in the low-to-mid current tier of fast-recovery rectifiers. The 400 V blocking voltage gives headroom for 240 VAC line rectification (peak ~340 V) with derating margin. The 500 mA average current limits it to auxiliary supply rails, gate-drive bootstrap circuits, and low-power PFC stages — not the bulk output of a 100 W supply. Forward voltage is 1.35 V max at 500 mA. At that current the conduction loss is 0.675 W — well within the glass package's thermal capability given the 175°C junction rating, but the designer should still size the copper pad area under the cathode tab to keep the junction below 125°C for long-life reliability. ## Glass hermetic — the package that survives The DO-213AA (GL34) is a glass-bodied, surface-mount package with hermetic sealing. Unlike plastic SMD packages, the glass construction resists moisture ingress and thermal cycling — relevant for sealed modules, outdoor telecom, downhole tools, and military/aerospace boards where conformal coating alone is not enough. The 7 pF capacitance at 4 V is low enough that it does not load high-frequency switching nodes. Junction temperature range spans -65°C to 175°C. That 175°C ceiling is the absolute-max junction temperature; for a 500 mA average current in a 85°C ambient, the junction typically runs 30–40°C above case temperature, so the margin is generous even in hot environments.","metaTitle":"Vishay EGL34G-E3/98 Fast Recovery Diode, 400V 500mA DO-213AA","metaDescription":"Vishay SUPERECTIFIER® EGL34G-E3/98 fast recovery diode: 400V, 500mA, 50ns trr, DO-213AA glass package.
