The Vishay BAS40-04-E3-08 is a Schottky diode array consisting of a quad configuration with a maximum breakdown voltage of 40 volts and a maximum current rating of 200mA. The diode is a common anode with a reverse voltage rating of 40 Volts. This diode array is designed specifically for low to medium power switching and rectification applications. It has low forward voltage drop and fast switching time, making it an excellent choice for use in regulated power supplies, level shifters, and battery chargers. This part is available in SOT-23, SOD-123, SMA, and SOD-323 package types.
