The 1N5817WS is a surface mount Schottky barrier diode package manufactured by TWGMC. It features a SOD-323 (Small Outline Diode-323) form factor, and is compliant with the RoHS (Restriction of Hazardous Substances) standard. The diode has a maximum reverse voltage of 40 volts, a maximum forward current of 1.0 amps, and a junction temperature range of -55 to 125°C. The low profile and high forward voltage drop help to minimize power losses in high-frequency applications such as switching regulators, bridges, and freewheeling. In addition, the reverse recovery time is fast, making it well suited for pulsed load applications.
