The SB540A-E3/54 is a Schottky barrier rectifier diode from Vishay General Semiconductor, part of the SB5xxA series. It features a maximum repetitive peak reverse voltage of 40V and an average forward rectified current of 5A. The forward voltage is typically 0.50V at 5A, enabling low conduction losses. The device can handle a peak forward surge current of 150A (8.3 ms single half sine-wave).
This diode is designed for low voltage, high frequency applications such as DC/DC converters, freewheeling diodes, and polarity protection circuits. It includes a guardring for overvoltage protection and offers extremely fast switching. The operating junction temperature range is -65°C to +150°C.
The SB540A is housed in a DO-201AD axial-lead package with matte tin plated leads, solderable per J-STD-002 and JESD 22-B102. The molding compound meets UL 94 V-0 flammability rating. Polarity is indicated by a cathode band. The E3 suffix denotes RoHS-compliant commercial grade.
