STMicroelectronics BAT54AFILM SMD Schottky Diode, SOT-23, Dual Common Anode

The STMicroelectronics BAT54AFILM is a high-performance, surface-mount Schottky diode designed for small-signal applications requiring fast switching and high efficiency. Part of the renowned BAT54 series, this dual common anode component features an extremely fast switching speed, low capacitance, and minimal forward and reverse recovery times, resulting in low conduction and negligible switching losses for superior energy management.

Its ECOPACK®2 compliant construction aligns with modern environmental standards. The diode is capable of withstanding a repetitive peak reverse voltage of 30V and offers an average forward current of 200mA, with a low forward voltage drop of just 400mV. This combination makes it ideal for protecting sensitive circuits and improving efficiency in power conversion paths.

Encapsulated in the compact and industry-standard SOT-23 package, it is perfectly suited for high-density PCB designs. With a robust operating junction temperature of up to 150°C and a forward surge current capability of 600mA, it provides reliable performance in demanding environments. The device's fast 5ns reverse recovery time is critical for high-frequency applications, minimising energy loss and heat generation.
