SF28

The SF28 is a fast recovery rectifier diode manufactured by Taiwan Semiconductor. It is commonly used in power supply circuits, switching regulators, freewheeling diodes, and other applications requiring fast switching and low forward voltage drop. The SF28 is well-suited for high-speed rectification due to its fast recovery time.

Applications:

– Switching Power Supplies: Used in the rectification stage for converting AC to DC with minimal switching losses.
– DC-DC Converters: Helps in efficient power conversion by minimizing reverse recovery losses.
– Freewheeling Diodes: Acts as a freewheeling diode in inductive load circuits, such as motor drivers and relay coils.
– Snubber Circuits: Utilized in snubber networks to protect switching devices from voltage spikes.
