About this product
SS14 is a 1 A, 40 V surface-mount Schottky barrier diode in an SMA package. Schottky diodes have a low forward voltage drop, so they are used for rectification, reverse-polarity protection and freewheeling in DC power circuits. The listing also cites the 1N5819 designation, which is a leaded part with the same 1 A / 40 V rating.

Frequently asked questions
Can I use this diode in place of a 1N5819 on a through-hole board?
Not directly. SS14 is a surface-mount part in an SMA package, while the 1N5819 is a leaded part, so a through-hole board needs the leaded version. The electrical rating is the same, but the footprint is different.
What should I keep in mind when using it for reverse-polarity protection?
Keep the forward current within the 1 A rating, and make sure the reverse voltage stays below 40 V. Schottky diodes have a forward drop that causes some power loss, so check the heat at your operating current.
