The fast recovery characteristic — under 500 ns — suits it for switching power supplies, output rectification in flyback and forward converters, and OR-ing diodes in redundant power architectures. ## Ratings that drive the BOM decision The 500 mV forward drop at 20 A per diode is the headline number for conduction loss. The 650 µA reverse leakage at 45 V is moderate.","metaTitle":"ST FERD40M45CT FERD Diode Array, 45V 20A, TO-220-3, Active","metaDescription":"ST FERD40M45CT dual common-cathode rectifier: 45V, 20A per diode, 500mV Vf, fast recovery <500ns.
