MBRF2045CTG

Diode Arrays Overview

The MBRF2045CTG is a dual Schottky barrier rectifier manufactured by onsemi, housed in a TO-220FP-3 through-hole package. It features a common cathode configuration with two silicon elements. The device supports a repetitive reverse voltage of 45 V and an average forward current of 10 A per diode leg. Key electrical parameters include a maximum forward voltage of 570 mV at 10 A, a reverse current of 100 uA, and a non-repetitive peak forward surge current of 150 A. It operates within a junction temperature range of -65 C to +175 C.

Diode Arrays Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm that the TO-220FP-3 package dimensions match the target PCB footprint. Ensure thermal management solutions accommodate the specified operating temperature range. Check for end-of-life notices or alternative sourcing requirements due to potential supply constraints.

Diode Arrays Selection Notes

Select this component when low forward voltage and high surge capability are required in a through-hole form factor. The common cathode configuration suits synchronous rectification or full-wave applications. Compare thermal resistance values against similar packages if space constraints exist. Verify that the 45 V rating aligns with the maximum circuit voltage spikes.

Diode Arrays Part Context

This part belongs to the MBRF series of Switchmode Power Rectifiers from onsemi. It utilizes platinum barrier metal Schottky technology for fast switching characteristics. The series is designed for high-efficiency power conversion applications where low forward voltage and high current handling are critical.
