SB540-A Description

Short technical summary and product information.

The SB540-A is a Schottky rectifier diode from Diodes Incorporated. It features a maximum reverse voltage of 40V and an average rectified current rating of 5A. The forward voltage drop is 550mV at 5A, enabling low power dissipation. The diode offers fast recovery speed of less than 500ns, making it suitable for high-frequency switching applications.

 

The device is housed in a DO-201AD axial lead through-hole package, allowing for easy mounting on printed circuit boards. It operates over a junction temperature range of -65°C to 125°C, providing reliable performance in demanding environments. The Schottky technology ensures low forward voltage and fast switching characteristics.

 

Typical applications include power supply rectification, polarity protection, and freewheeling diodes in converters. The SB540-A is a robust choice for general-purpose rectification where low forward voltage and fast switching are required.
