About this product
A 20 A, 100 V Schottky rectifier diode in a fully isolated TO-220F package. Schottky diodes have a low forward voltage drop, which makes them suitable for output rectification in switch-mode power supplies, DC-DC converters and freewheeling in motor and relay circuits.

Frequently asked questions
Does the TO-220F package need an insulating washer on a heatsink?
Usually not. TO-220F is fully isolated, so its metal tab is not electrically connected to the diode terminals and it can be mounted directly on a heatsink. Confirm the heatsink's grounding arrangement in your circuit.
How should I choose the reverse voltage margin?
Choose a reverse voltage well above the peak voltage across the diode in your circuit. For high-current use, provide adequate heatsinking, since power loss grows with the forward current.
