The P5L45F-A SMAF-A RoHS is a Schottky Barrier Diode (SBD) manufactured by PFC Device. It is a 55-volt dual SBD device designed to help protect against electrostatic discharge (ESD) and other overvoltage events, including electro-mechanical breaks. It features low forward voltage drop, high reverse saturation current, and rapid switching. The device is designed to operate across a wide range of temperatures from -40°C to +125°C, and is RoHS compliant for both ESD protection and other applications.
