SB540-T Description

Short technical summary and product information.

The SB540-T is a 5.0A Schottky barrier rectifier from Diodes Incorporated, designed for low-voltage, high-frequency applications. It features a peak repetitive reverse voltage (VRRM) of 40V and an average rectified current (Io) of 5A. The forward voltage is typically 550 mV at 5A, contributing to low power loss and high efficiency.

 

This device offers a high surge overload rating of 150A peak (60Hz half-sine wave), making it suitable for applications requiring robust transient protection. It is constructed with an epitaxial design and a guard ring die for enhanced reliability.

 

The SB540-T is housed in a DO-201AD axial-lead case with bright tin-plated terminals. It is rated for operation from -65°C to 125°C and has a moisture sensitivity level of 1 (unlimited). The part is RoHS3 compliant and has a lead-free finish.
