MBRP3045NTU

Diode Arrays Overview

The MBRP3045NTU is a dual Schottky barrier rectifier manufactured by Fairchild Semiconductor, now part of onsemi. It features a common cathode configuration with two silicon elements housed in a TO-220AB package. The device is rated for a repetitive peak reverse voltage (Vrrm) of 45 V and an average forward rectified current (Io) of 30 A per element. Key electrical parameters include a maximum non-repetitive peak forward surge current (Ifsm) of 150 A and a maximum DC reverse leakage current (Ir) of 1 mA at 25°C. The component operates within a junction temperature range of -65°C to +175°C.

Diode Arrays Feature Summary

• Schottky barrier technology provides low forward voltage drop and minimal power loss.
• Common cathode dual configuration allows for efficient bridge rectification or center-tapped applications.
• High thermal stability supports operation up to a 175°C junction temperature.

Diode Arrays Applications

• DC-to-DC converters
• Free-wheeling diodes in inductive load circuits
• Power supply output rectification

Diode Arrays Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor has been integrated into onsemi. Ensure the ordering suffix matches the required packaging format, typically tubes for this through-hole variant. Confirm RoHS compliance status and lead-free specifications against the specific batch documentation provided by the authorized distributor or manufacturer.

Diode Arrays Selection Notes

Select this component when a 45 V rating and 30 A continuous current capability are required in a dual common cathode arrangement. The TO-220AB package offers robust mechanical mounting and heat dissipation suitable for high-current applications. Compare forward voltage characteristics and thermal resistance values against alternative packages if space constraints exist.

Diode Arrays Part Context

This device belongs to the MBRP series of Schottky rectifiers designed for general-purpose power conversion. The series emphasizes efficiency through low forward voltage drops. The MBRP3045NTU specifically targets applications requiring moderate voltage blocking capabilities combined with high current handling in a standard through-hole footprint.

Diode Arrays Replacement Considerations

Direct substitutes may include the MBRP3045N from onsemi, reflecting the corporate integration. Verify pinout compatibility and thermal performance metrics before substitution. Alternative manufacturers offering equivalent 45 V, 30 A dual Schottky rectifiers in TO-220 packages should be evaluated based on specific forward voltage and leakage current tolerances.
