A Silicon Schottky Barrier Diode (SBD) chip is a semiconductor device that allows current to flow in one direction by using a metal-semiconductor junction. SBDs are used as rectifiers in power supply circuits and have fast switching speeds, low forward voltage drop, and low reverse leakage current. Silicon SBD chips are widely used in electronic devices such as smartphones, computers, and televisions, as well as in high-frequency power applications such as RF power amplifiers and microwave ovens. They are popular due to their reliability, low power loss, and ability to operate at high temperatures.
