FSV540 Description

Short technical summary and product information.

The FSV540 is a 5A, 40V Schottky barrier rectifier designed by On Semiconductor for low forward voltage drop and high efficiency. With a typical forward voltage of 474 mV and a maximum of 520 mV at 5 A, it minimizes power loss in rectification circuits. The device offers a non-repetitive peak forward surge current rating of 150 A, providing robustness during startup or fault conditions.

 

This rectifier is housed in a very low profile TO-277-3LD package with a typical height of 1.1 mm, suitable for space-constrained surface-mount designs. Thermal performance is specified with junction-to-ambient thermal resistances of 100 °C/W (minimum land pattern) and 40 °C/W (maximum land pattern), enabling effective heat dissipation. The operating junction temperature range spans -55°C to 150°C.

 

The FSV540 is RoHS compliant, Pb-Free, and halogen free, meeting current environmental standards. Typical applications include output rectification in switching power supplies, freewheeling diodes, and reverse polarity protection circuits.
