Radio CompanyThe LRB521S-40T1G is a Schottky Barrier Diode (SBD) SOD-523 RoHS-compliant diode manufactured by the Leshan Radio Company. It is a surface-mount SOD-523 package (2-pin, SOT-323) with an overall SMD package size of only 3mm x 1.2mm. This diode is designed for general purpose rectification and has the following features: low forward voltage drop, high temperature operation (up to 175°C), and fast switching speed. It has a maximum forward current of 40mA, reverse current of 5µA, and reverse voltage of 5V, and has high temperature, high humidity, and high vibration resistance. The LRB521S-40T1G is commonly used in automotive, consumer electronics and computer peripheral applications.
