The RFN20NS4S is a fast recovery diode from ROHM Semiconductor GmbH, designed for general rectification applications. It features low switching loss and high current overload capacity, making it suitable for efficient power supply designs. The diode has a maximum reverse voltage rating of 430V and can handle an average rectified forward current of 20A at a case temperature of 30¬8C. It also supports a non-repetitive forward current surge peak of 100A. The thermal resistance from junction to case is specified at 1.3 to 1.55¬8C/W, depending on the forward current. The diode operates effectively within a junction temperature range of -55¬8C to 150¬8C. Its reverse recovery time is characterized at 22 to 30ns, which contributes to its fast recovery capabilities. This product is suitable for engineers looking for reliable performance in high-efficiency applications.
ROHM's fast recovery diodes are ultra high-speed, low VF, and suited for significant efficiency increase of switching power supply as well as reduction of switching loss.
