MBR20L45CTG

Diode Arrays Overview

The MBR20L45CTG is a dual common cathode Schottky barrier rectifier manufactured by onsemi. It features a silicon construction housed in a TO-220AB package with three through-hole terminals. The device supports a repetitive reverse voltage of 45 V and an average forward current of 10 A per diode leg, totaling 20 A. Key electrical parameters include a maximum forward voltage of 0.47 V at 10 A, a peak non-repetitive forward surge current of 200 A, and a maximum reverse leakage current of 1.2 mA. It operates within a junction temperature range of -65°C to +150°C.

Diode Arrays Feature Summary

• Guard-ring structure provides enhanced stress protection for improved reliability under high-voltage conditions.
• Low forward voltage drop design minimizes power loss and increases overall system efficiency.
• High surge current capacity ensures robust performance during transient load events.

Diode Arrays Applications

• Output rectification in switch-mode power supplies
• Power management circuits requiring low loss
• Freewheeling diodes in DC-DC converters

Diode Arrays Procurement Notes

Verify the specific suffix 'G' indicates lead-free and RoHS compliance status as defined by onsemi standards. Confirm the package variant matches the required thermal and mechanical constraints for the target PCB layout. Ensure the ordering part number aligns with the active production status to avoid obsolete component risks during long-term manufacturing.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or freewheeling applications. The 45 V rating suits low-voltage output stages where minimizing conduction losses is critical. Compare the 0.47 V forward voltage against alternative technologies to ensure optimal thermal management and efficiency targets are met for the specific power density requirements.

Diode Arrays Part Context

This device belongs to the MBR20L series of Schottky rectifiers from onsemi, designed for high-efficiency power conversion. It shares the same pinout and general form factor as other variants in the family but differs in voltage and current ratings. The series is engineered for applications demanding fast switching speeds and low reverse recovery charge.

Diode Arrays Replacement Considerations

Direct substitutes include MBR20L45WTG, which shares identical electrical characteristics and pin configuration. Verify that any cross-reference maintains the same TO-220AB package dimensions and thermal resistance values to ensure compatibility with existing heatsinking solutions.
