BAT54AWFILMY Description

Short technical summary and product information.

This BAT54AWFILMY is a Schottky diode array from STMicroelectronics featuring two diodes in a common anode configuration. It is rated for a maximum reverse voltage of 40V and a forward current of 300mA per diode. The typical forward voltage is 900mV at 100mA with a fast reverse recovery time of 5ns, making it suitable for high-speed switching applications. The diode offers low reverse leakage current of 1µA at 30V reverse voltage.

 

Designed for automotive applications, this component is part of the Q Automotive series and operates over a junction temperature range of -40°C to 150°C. The surface-mount package is SC-70 (SOT-323), which allows for compact PCB layouts. The common anode configuration simplifies design in circuits requiring multiple Schottky diodes with a shared anode connection, such as polarity protection, OR-ing diodes, and high-speed rectification in automotive electronics.
