The BAT46W is a Schottky Barrier Diode (SBD) manufactured by Changjiang. It is packaged in a small SOD-123 RoHS form factor and is designed to provide improved performance in comparison to normal diodes. It features a very low forward voltage, a high speed switching, and a low power dissipation. The BAT46W operates at a maximum reverse voltage of 30V, a maximum forward current of 100mA, and a maximum junction temperature of 150C. Its typical forward voltage is 0.45V @ 25C, and its maximum power dissipation is 150mW. It is designed for general purpose switching applications, including use in RF circuits, ESD protection, and low power rectification.
