MBRF20100CTG

Diode Arrays Overview

The MBRF20100CTG is a Schottky barrier rectifier manufactured by onsemi, designed for high-efficiency power conversion applications. It features a common cathode configuration with two internal diodes housed in an ITO-220AB (TO-220) through-hole package. The device supports a maximum repetitive reverse voltage of 100 V and a total average forward current of 20 A. Key electrical characteristics include a low forward voltage drop to minimize conduction losses and a peak non-repetitive forward surge current rating of 150 A. The component operates within a temperature range of -65°C to +175°C junction temperature.

Diode Arrays Feature Summary

• Schottky barrier technology ensures majority carrier conduction for fast switching speeds and minimal reverse recovery charge.
• Guard-ring design provides enhanced protection against voltage stress and improves reliability under high-voltage conditions.
• Low forward voltage drop reduces power dissipation and increases overall system efficiency in rectification circuits.

Diode Arrays Applications

• Output rectification in switch-mode power supplies
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits in automotive and industrial electronics

Diode Arrays Procurement Notes

Verify the specific suffix 'G' indicates lead-free and RoHS compliance status as per onsemi's standard product labeling conventions. Confirm the package outline matches the ITO-220AB mechanical dimensions provided in the official datasheet. Ensure the ordering part number aligns with the required voltage and current ratings for your specific circuit design requirements before finalizing procurement.

Diode Arrays Selection Notes

Select this component when designing circuits requiring high current handling at low voltage drops. The 100 V rating suits applications where input voltages may fluctuate but remain below this threshold. Consider thermal management strategies due to the 20 A current capacity, ensuring adequate heatsinking or PCB copper area to maintain junction temperatures within the specified operating range during continuous operation.

Diode Arrays Part Context

This device belongs to onsemi's MBRF series of high-current Schottky rectifiers. The series offers various voltage ratings from 20 V to 100 V, all sharing similar mechanical footprints and thermal characteristics. This specific model fills the gap between lower voltage options and higher voltage variants, providing a balanced solution for mid-range voltage power supply designs requiring robust surge capability.

Diode Arrays Replacement Considerations

Direct replacements must match the 20 A current, 100 V voltage, and TO-220 package. Verify pinout compatibility, specifically the common cathode configuration. Check if alternative manufacturers offer equivalent guard-ring protection and surge current ratings to ensure no derating is necessary in the existing design.
