MBR745

Single Diodes Overview

The MBR745 is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for low voltage and high frequency applications. It features a single configuration in a TO-220-2 through-hole package. Key electrical parameters include a repetitive reverse voltage (Vrrm) of 45 V and an average forward current (If) of 7.5 A. The device exhibits a maximum forward voltage drop (Vf) of 840 mV at rated current and a reverse leakage current (Ir) of 100 uA. It supports a forward surge current (Ifsm) of 150 A and operates within a junction temperature range of -65 °C to +150 °C.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific manufacturer source, as the MBR745 part number is historically associated with General Semiconductor and other vendors. Confirm current availability status, as many listings indicate end-of-life or discontinuation. Ensure the datasheet revision matches the required technical specifications before procurement. Cross-reference pinouts and thermal characteristics with the specific supplier's documentation to avoid integration errors.

Single Diodes Selection Notes

Select this component for designs requiring robust Schottky rectification with high current handling in a through-hole package. The 45 V rating suits low-voltage DC-DC converters and power supplies. Consider the TO-220-2 package for adequate heat dissipation without active cooling. Verify that the 7.5 A continuous current rating meets the peak load requirements of the target application circuit.

Single Diodes Part Context

This component belongs to the Schottky Barrier Rectifier category, characterized by fast switching speeds and low forward voltage drops compared to standard PN junction diodes. The MBR745 variant specifically targets 45 V applications within the broader family of high-current rectifiers available from various semiconductor manufacturers including Diodes Incorporated and former General Semiconductor lines.
