Frequently asked questions
Is this diode fast enough for high-frequency switching?
Standard silicon rectifiers recover more slowly than Schottky or fast-recovery diodes. For high-frequency switching circuits, choose a fast-recovery or ultrafast type instead.
Does it need cooling at 6 A?
Yes, at 6 A the diode dissipates considerable heat. Check the package and thermal limits in the datasheet and add a heatsink if needed.
