The STMicroelectronics FERD40M45CT is a dual common-cathode rectifier built on the FERD (Field Effect Rectifier Diode) structure. 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.
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.
Yes, it is ROHS3 Compliant.
