MBR2045CTG

Diode Arrays Overview

The MBR2045CTG is a SWITCHMODE Power Rectifier manufactured by onsemi, featuring a dual common cathode configuration in a TO-220AB package. It utilizes silicon Schottky barrier technology with a platinum barrier metal for stress protection. The device supports a total average forward current of 20 A (10 A per diode leg) and a repetitive peak reverse voltage of 45 V. Key electrical characteristics include a maximum instantaneous forward voltage of 840 mV at 10 A and a non-repetitive peak forward surge current of 150 A. It operates within a junction temperature range of -65°C to +175°C.

Diode Arrays Feature Summary

• SWITCHMODE design with Guard-Ring structure for transient stress protection
• Low forward voltage drop for high efficiency and low power loss
• High surge current capability suitable for demanding switching applications

Diode Arrays Applications

• Output rectification in switch-mode power supplies
• Power management circuits
• Free-wheeling diodes in low voltage high frequency inverters
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific datasheet revision when sourcing, as onsemi has published multiple versions (e.g., Rev. 8 from May 2008 and Rev. 12 from July 2016). Confirm that the TO-220AB package matches your thermal and mechanical requirements. Ensure the Pb-free designation aligns with your assembly process compliance standards. Cross-reference pinouts if substituting from other manufacturers like Diodes Incorporated or Microchip.

Diode Arrays Selection Notes

Select this component for applications requiring robust transient protection and high efficiency in low-voltage DC-DC conversion. The 10 A per leg rating makes it suitable for split-phase or center-tapped rectifier topologies. Consider the 175°C junction temperature rating for high-temperature environments. Compare forward voltage specifications against alternatives if minimizing conduction losses is critical.

Diode Arrays Part Context

This part belongs to the MBR2045CT series of SWITCHMODE Power Rectifiers. It is functionally similar to parts like MBR2045CT and MBR3045ST but differs in packaging and specific manufacturer variations. The 'G' suffix typically denotes lead-free and RoHS compliance. It serves as a replacement for older standard rectifiers where lower forward voltage and higher reliability are required.

Diode Arrays Replacement Considerations

Direct substitutes include MBR2045CT (generic equivalent) and MBR2045CTe3/TU (Microchip variant). Verify pin compatibility and thermal resistance values when replacing. Note that while electrical ratings are similar, physical dimensions and marking codes may vary between manufacturers.
