MBR0540

Single Diodes Overview

The MBR0540 is a Schottky rectifier manufactured by onsemi, housed in an SOD-123 surface-mount package. It features a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 500 mA. The device exhibits a low forward voltage characteristic, with a maximum value of 620 mV at 1.0 A. Non-repetitive peak forward surge current is rated at 5.5 A. Thermal resistance from junction to ambient is 206 °C/W, while the junction-to-lead thermal resistance is 118 °C/W. The component supports a storage temperature range from -65°C to +150°C and an operating junction temperature up to +125°C.
