MBR3045WTP

Diode Arrays Overview

The MBR3045WTP is a Schottky barrier rectifier manufactured by SMC Diode Solutions. It features a maximum average forward rectified current of 30 A and a maximum repetitive peak reverse voltage ranging from 20 V to 100 V, depending on the specific suffix variant. The device utilizes metal-to-silicon construction for majority carrier conduction, resulting in low power loss and high efficiency. It is designed with a guard ring structure to provide transient protection. The component is available in surface-mount packaging, specifically the TO-263AB (D2PAK) form factor, suitable for high-current applications requiring robust thermal performance.

Diode Arrays Feature Summary

• Schottky barrier technology ensures low forward voltage drop and minimal power loss during operation.
• Guard ring design provides enhanced protection against transient voltage events.
• Majority carrier conduction mechanism enables high switching efficiency and fast response times.

Diode Arrays Applications

• Free-wheeling diodes in synchronous rectification circuits
• Power supply output rectification

Diode Arrays Procurement Notes

Verify the exact voltage suffix (e.g., 20, 30, 40, 45, 60, 80, 100) when ordering, as the base part number covers a range of reverse voltage ratings. Confirm the package type matches the required PCB footprint. Ensure the supplier provides original manufacturer documentation to validate authenticity and compliance with RoHS standards. Cross-reference the full DigiKey or manufacturer part number to avoid confusion with through-hole variants.

Diode Arrays Selection Notes

Select this component for applications demanding high current handling up to 30 A with reduced heat dissipation needs due to low forward voltage. Consider the thermal resistance of the TO-263AB package for adequate heat sinking. Compare leakage current specifications at elevated temperatures if operating in high-ambient environments. Ensure the selected voltage rating exceeds the maximum circuit reverse voltage with appropriate safety margins.

Diode Arrays Part Context

This device belongs to the MBR30xxW series of Schottky rectifiers from SMC Diode Solutions. The 'W' suffix typically denotes the surface-mount D2PAK package, distinguishing it from through-hole counterparts like the MBR3045. This series is engineered for general-purpose power rectification where efficiency and surge capacity are critical design parameters.

Diode Arrays Replacement Considerations

Direct replacements include other 30 A Schottky rectifiers in the TO-263AB package with matching voltage ratings, such as those from Micro Commercial Components or Nexperia. Verify pinout compatibility and thermal characteristics before substitution.

Diode Arrays FAQ

What does the 'CA' or numeric suffix indicate in the part number?

The suffix indicates the maximum repetitive peak reverse voltage rating, such as 20V, 30V, 40V, or 45V, allowing selection based on circuit requirements.

Is the MBR3045WTP a dual diode configuration?

No, it is a single diode component. Dual configurations in this current class typically use different package types or part number prefixes.

What is the typical forward voltage drop at rated current?

The forward voltage is typically around 0.76 V at 30 A, contributing to its high efficiency compared to standard PN junction rectifiers.
