Its 35 ns reverse recovery time (trr) is the spec that determines switching losses in a 100 kHz PFC boost stage or a flyback snubber — every nanosecond of stored charge that has to be swept out adds to the junction temperature rise. ## Forward drop and thermal budget At the rated 8 A forward current the maximum forward voltage is 975 mV. That 7.8 W conduction loss at full load has to be sunk through the TO-263AB (D²PAK) package's exposed pad — the board copper area under the tab sets the junction-to-ambient thermal resistance. The junction temperature range spans -65°C to 175°C, giving headroom for high-ambient environments like an outdoor telecom rectifier or an under-hood DC-DC converter. ## Package and footprint fit Surface-mount in a TO-263-3 (D²PAK) case — two leads plus the tab. The footprint is shared with the standard D²PAK outline; the tab is the cathode. Reverse leakage is 5 µA at the 200 V rated blocking voltage, which is low enough that it does not shift the bias point in a voltage-multiplier string. ## Lifecycle and compliance — no LTB surprise The FRED Pt® series is Vishay's established ultrafast family; the -M3 suffix indicates the ROHS3-compliant version.","metaTitle":"VS-MURB820-M3 FRED Pt® Diode, 200V 8A, 35ns trr, TO-263AB","metaDescription":"VS-MURB820-M3 Vishay FRED Pt® ultrafast rectifier, 200V 8A, 35ns trr, TO-263AB (D²PAK).
