About this product
SR3100 Schottky barrier rectifier diode rated 3 A forward current and 100 V reverse voltage. Schottky diodes have a lower forward voltage drop than standard silicon rectifiers, which suits switch-mode power supplies, freewheeling and reverse-polarity protection.

Frequently asked questions
Is this diode suitable for switch-mode power supplies?
Its low forward drop and 100 V reverse rating make it a common choice in SMPS output and freewheeling positions, provided the reverse voltage and peak current stay within the datasheet limits.
Does it need a heatsink?
At currents near 3 A, the diode generates heat. Provide adequate copper area or a heatsink, and check the package and thermal limits in the datasheet.
