MBRF20H100CTG

Diode Arrays Overview

The MBRF20H100CTG is a dual common cathode Schottky barrier rectifier manufactured by onsemi. It features a TO-220 Fullpak (TO-220FP) package with an isolated tab for heat dissipation. The device supports a peak repetitive reverse voltage of 100 V and provides a total average rectified forward current of 20 A, distributed as 10 A per diode leg at a case temperature of 162°C. It withstands a nonrepetitive peak surge current of 250 A and operates at junction temperatures up to 175°C. The maximum thermal resistance from junction to case is 2.5°C/W.

Diode Arrays Procurement Notes

Verify the specific package style matches the design requirements, as this part number corresponds to the TO-220 Fullpak variant. Confirm that the application environment stays within the specified thermal limits to maintain reliability. Check for any recent obsolescence notices or alternative recommendations from the manufacturer before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or freewheeling applications. Ensure the PCB layout accommodates the TO-220FP footprint and allows adequate airflow or heatsinking to manage the thermal resistance. Validate that the 100 V rating exceeds the circuit's peak reverse voltage under all operating conditions.

Diode Arrays Part Context

This device belongs to the MBR20H100CT family of Switch-mode Power Rectifiers. Other members include the standard TO-220 MBR20H100CTG and the surface-mount D2PAK MBRB20H100CTT4G. The MBRF20H100CTG specifically utilizes the fullpak variant for enhanced mounting stability and thermal performance compared to the standard through-hole version.

Diode Arrays Replacement Considerations

Consult the official datasheet for discontinued status updates. Verify pinout compatibility and thermal resistance values when substituting with similar Schottky rectifiers from other manufacturers.
