The BAT46WFILM is a small signal switching diode from STMicroelectronics, available in the SOD-323F package, engaging the protection in a very small form factor. This diode is mainly employed for high frequency applications, providing secure protection from high voltage and transients, supporting the reverse operation down to 3 Volt. Thanks to its ultra-fast recovery time, it can be used as a shield for tiny and fast switching signals, in order to ensure secure and reliable operation.
