The 520 mV maximum forward voltage at 20 A keeps conduction losses low — important when the diodes share a heatsink tab in the TO-263AB package. Reverse leakage is specified at 600 µA at the 30 V maximum reverse voltage. The 150°C maximum junction temperature gives headroom for high-ambient or forced-air designs. The large tab on the D²Pak provides a low thermal resistance path to the PCB copper — a solid thermal via pattern under the tab is expected for sustained 20 A per diode. The fast recovery speed (under 500 ns, above 200 mA) suits switching power supplies and DC-DC converter output rectification where reverse-recovery losses matter.","metaTitle":"RBR40NS30ATL ROHM Schottky Diode, 20A, 30V, TO-263AB","metaDescription":"Active ROHM RBR40NS30ATL Schottky diode, 20A average rectified per diode, 30V reverse, 520mV Vf, TO-263AB (D2Pak) surface mount.
