MBR3045WT

Diode Arrays Overview

The onsemi MBR3045WT is a silicon Schottky rectifier featuring a dual anode common cathode configuration housed in a TO-220AB package. It supports a maximum repetitive peak reverse voltage of 45V and an average forward current of 15A per anode. The device exhibits a typical forward voltage drop of 820mV at 15A and a maximum reverse leakage current of 200µA at rated voltage. It withstands a non-repetitive peak forward surge current of 150A and operates within a junction temperature range of -65°C to +175°C.

Diode Arrays Feature Summary

• Dual anode common cathode topology for bridge or center-tapped applications
• Ultra-fast switching characteristics with low forward voltage drop
• High thermal stability with extended operating junction temperature up to 175°C

Diode Arrays Applications

• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Power supply input protection

Diode Arrays Procurement Notes

Verify the specific suffix against official datasheets, as variations may indicate different packaging or compliance standards. Confirm RoHS status and lead-free composition requirements with the manufacturer before procurement. Ensure the ordering part number matches the exact electrical specifications required for the design.

Diode Arrays Selection Notes

Select this component for designs requiring a 45V blocking capability with high current handling in a through-hole package. Compare forward voltage and thermal resistance against alternatives if efficiency or heat dissipation is critical. Ensure the chosen package fits the PCB layout constraints and thermal management strategy.

Diode Arrays Part Context

This device belongs to the MBR series of Schottky rectifiers from onsemi, designed for general-purpose power conversion. It complements single-diode variants like the MBR1045G by providing two rectifying elements in one package, simplifying assembly for full-wave rectification topologies.

Diode Arrays Replacement Considerations

The MBR2545CTG is listed as an alternative with similar electrical ratings but lower current capacity. Verify pinout compatibility and thermal performance when substituting.
