MBR745G

Single Diodes Overview

The MBR745G is a single silicon Schottky barrier rectifier manufactured by onsemi. It features an average forward current rating of 7.5 A and a repetitive peak reverse voltage of 45 V. The device exhibits a maximum forward voltage drop of 840 mV at rated current and supports a forward surge current of 150 A. It operates within a temperature range of -65 °C to +175 °C junction temperature, with a typical reverse leakage current of 100 µA. The component is housed in a TO-220-2 through-hole package.

Single Diodes Feature Summary

• Utilizes silicon Schottky barrier technology for high-frequency switching performance
• Incorporates guard ring design for enhanced over-voltage protection stability
• Provides low forward voltage drop characteristics to minimize conduction losses

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Free-wheeling diode applications in inductive load management
• DC-DC converter output rectification stages

Single Diodes Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the procurement channel provides valid traceability data consistent with manufacturer standards. Cross-reference the part number with the latest datasheet revision to confirm compliance with current environmental directives such as RoHS and REACH requirements before finalizing acquisition.

Single Diodes Selection Notes

Select this component when circuit designs require a robust single-diode solution capable of handling moderate surge currents up to 150 A. The TO-220-2 package facilitates effective thermal dissipation for continuous 7.5 A operation. Consider the 45 V reverse voltage rating to ensure adequate margin above the maximum expected operating voltage. Evaluate the 840 mV forward voltage drop impact on overall system efficiency during high-current phases.

Single Diodes Part Context

This device belongs to the MBR745 series of Schottky rectifiers from onsemi. It shares the same voltage and current ratings as the MBRP745TU but differs in package style and specific parameter tolerances. The series is designed for general-purpose applications requiring reliable rectification with improved switching speeds compared to standard p-n junction diodes.

Single Diodes Replacement Considerations

The MBRP745TU serves as a functional alternative within the same product family. Verify that the replacement's reverse leakage current and forward voltage specifications align with the original design constraints. Confirm that the physical footprint and pinout compatibility match the existing PCB layout requirements.
