The B5817WS is a Schottky Barrier Diode (SBD) manufactured by Bourne. It is a surface-mount device (SMD) and is constructed from an SOD-323 RoHS package, making it suitable for use in applications where space is limited. The diode has a low forward voltage drop, allowing low forward power dissipation and high switching speeds. It has an maximum current rating of 500mA and a breakdown voltage of 30V, making it suitable for a variety of applications. The B5817WS offers excellent surge handling capabilities to protect your circuit against extreme voltage and current conditions. The device also features a wide operating temperature range of -55°C to +150°C, making it suitable for use in extreme temperatures.
