MBRF3045CT-LJ

Diode Arrays Overview

The MBRF3045CT-LJ is a dual common cathode Schottky barrier rectifier manufactured by Diodes Incorporated. It utilizes an ITO-220AB (TO-220F-3) package and contains two independent silicon elements. Each leg supports a peak repetitive reverse voltage of 45 V and an average rectified output current of 15 A, totaling 30 A for the device. The maximum forward voltage drop is 0.62 V at 15 A and +25°C, with a maximum leakage current of 0.1 mA under the same conditions. The component operates within a temperature range of -55°C to +150°C.

Diode Arrays Feature Summary

• Guard ring die construction provides transient protection against overvoltage events.
• Qualified to AEC-Q101 standards to ensure high reliability in automotive applications.
• Lead-free finish and halogen-free green compound meet environmental directives.

Diode Arrays Applications

• Polarity protection diodes
• Re-circulating diodes
• Switching diodes

Diode Arrays Procurement Notes

Verify the specific ordering suffix LJ corresponds to the ITO-220AB case style and tube packaging containing 50 pieces per tube. Confirm that the required RoHS compliance aligns with EU Directive 2002/95/EC and 2011/65/EU specifications. Ensure the application environment does not exceed the specified thermal resistance limits for the selected mounting configuration.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for low voltage, high frequency rectification. The ITO-220AB package offers an isolated cathode connection suitable for heatsinking. Consider the 200 A non-repetitive peak forward surge current capability for circuits experiencing high initial inrush currents or transient spikes.

Diode Arrays Part Context

This part belongs to the MBR series of Schottky barrier rectifiers from Diodes Incorporated. It shares electrical characteristics with the through-hole TO-220AB variant (MBR3045CT), differing primarily in the surface-mount compatible ITO-220AB package design. The series is designed for commercial applications requiring low forward voltage drop and high efficiency.

Diode Arrays Replacement Considerations

The MBR3045CT serves as a direct functional equivalent utilizing the TO-220AB through-hole package instead of the ITO-220AB form factor.
