MBR1545CTG

Diode Arrays Overview

The MBR1545CTG is a silicon Schottky barrier rectifier manufactured by onsemi, housed in a TO-220-3 through-hole package. It features a dual common cathode configuration with a total average forward current rating of 15 A (7.5 A per diode leg) and a maximum repetitive reverse voltage of 45 V. The device exhibits a typical forward voltage of 840 mV at 15 A and supports 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

• Center-tap configuration for efficient power rectification
• Low forward voltage drop for high efficiency and reduced power loss
• High surge current capacity for robust transient protection
• Guard ring design provides overvoltage protection

Diode Arrays Applications

• Switching power supply output rectification
• Free-wheeling diodes in inverter circuits
• Reverse battery protection systems

Diode Arrays Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the TO-220-3 package dimensions match your PCB footprint requirements. Ensure thermal management solutions are adequate for the intended operating temperature range up to 175°C junction temperature.

Diode Arrays Selection Notes

Select this component for low-voltage, high-frequency applications requiring fast switching speeds and minimal conduction losses. The 15 A total current rating suits moderate power levels where center-tap topology is preferred. Consider the 45 V reverse voltage limit when designing against potential voltage spikes in the circuit.

Diode Arrays Part Context

This part belongs to the MBR15 series of Schottky barrier rectifiers from onsemi. It shares the same electrical characteristics as the MBR1545CT but differs in packaging and manufacturing origin. The G suffix indicates lead-free and halogen-free compliance, aligning with modern environmental standards for electronic components.

Diode Arrays Replacement Considerations

The MBR3045STG is documented as an alias for the MBR2545CTG, which has different current ratings. For direct replacement, verify equivalent current and voltage ratings in alternative Schottky rectifiers from other manufacturers, ensuring pin compatibility and thermal performance match.
