Frequently asked questions
Is it suitable for mains rectification?
Its high reverse voltage rating suits rectification from mains-derived supplies at line frequency. For high-frequency switching converters, check the datasheet's reverse recovery time and choose a fast-recovery diode if needed.
Does it need a heatsink?
At high current it should be mounted on a heatsink with a suitable thermal interface. Check the thermal ratings in the datasheet to size the heatsink for your load.
