What is BAS40?
This is Schottky barrier (double) diodes. The Schottky Barrier Diode (SBD) is formed by the junction of a metal contact and a semiconductor material, typically silicon or gallium arsenide. Unlike a p-n junction diode, which uses a p-type and an n-type semiconductor material, the SBD uses a metal and a semiconductor material. The metal is chosen for its low work function, which results in a small barrier height at the metal-semiconductor interface, allowing for efficient carrier injection. The main advantage of an SBD is its fast switching speed and low forward voltage drop, which makes it ideal for high-frequency and high- |
