STMICROELECTRONICS BAR43FILM Schottky Rectifier, 30V, 100mA, SOT-23

The STMICROELECTRONICS BAR43FILM is a high-performance, surface-mount Schottky rectifier diode designed for efficient power management in compact electronic circuits. Featuring a metal-to-silicon construction, it offers a very low forward voltage drop and exceptionally fast switching speeds, making it ideal for applications where minimising power loss and maximising efficiency are critical.

This general-purpose signal diode is characterised by its very low turn-on voltage, which results in significantly reduced conduction losses compared to standard diodes. Its negligible switching losses further enhance overall circuit efficiency, particularly in high-frequency operations. The device is housed in a space-saving SOT-23 package, making it perfect for modern, densely populated printed circuit boards (PCBs) where board real estate is at a premium.
