MBRF2545CTG

Diode Arrays Overview

The MBRF2545CTG is a Switch-mode Schottky Power Rectifier manufactured by onsemi, utilizing a large area metal-to-silicon diode with epitaxial construction and oxide passivation. It features matched dual die construction in an electrically isolated TO-220 Fullpak package (Case 221D). The device supports a peak repetitive reverse voltage of 45 V and an average rectified forward current of 25 A total (12.5 A per leg) at TC = 125°C. Maximum instantaneous forward voltage is 0.7 V at 12.5 A and 25°C. Non-repetitive peak surge current reaches 150 A. Operating junction temperature ranges from -65°C to +175°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix 'G' confirms Pb-Free status as documented in the datasheet. Confirm the package type matches the TO-220 Fullpak (Case 221D-03) specifications. Ensure thermal management aligns with the maximum junction temperature rating of 175°C and the specified thermal resistance values provided in the official documentation.

Diode Arrays Selection Notes

Select this component for applications requiring high efficiency and low forward voltage drop in switch-mode environments. The electrically isolated case simplifies heatsinking without additional insulators. Verify that the 45 V reverse voltage rating accommodates circuit transients and that the 12.5 A per leg current capacity meets the load requirements under expected thermal conditions.
