Vishay SB540AE354 Schottky Barrier Rectifier

The SB540A is a high-speed, low forward voltage Schottky barrier rectifier ideal for low voltage, high-frequency applications such as inverters, freewheeling, DC-DC converters, and polarity protection. Featuring a guardring for overvoltage protection, it offers very small conduction losses and extremely fast switching capabilities. This RoHS-compliant device has a case type DO-201AD with matte tin plated leads for solderability, and is rated for a maximum repetitive peak reverse voltage of 40V and a forward voltage of 0.5V at 5A. Suitable for high frequency operation and demanding environments, it ensures reliable performance with a thermal resistance of 10°C/W and a junction temperature range of -65°C to +150°C.
