MBR2045CTP

Diode Arrays Overview

The MBR2045CTP is a discontinued dual Schottky barrier rectifier manufactured by Diodes Incorporated. It utilizes an ITO-220S package with an isolated heat sink tab. The device features two common cathode elements, each rated for a peak repetitive reverse voltage of 45V and an average rectified output current of 10A, totaling 20A. Electrical characteristics include a maximum forward voltage drop of 0.65V at 10A and 25°C, and a non-repetitive peak forward surge current of 150A. Thermal resistance from junction to case is 3°C/W per leg.

Diode Arrays Feature Summary

• Schottky Barrier Chip construction providing low forward voltage drop and soft, fast switching capability
• ITO-220S case design where the heat sink tab is electrically isolated from the cathode
• Common cathode configuration supporting high efficiency in power applications

Diode Arrays Applications

• High frequency switch mode power supplies
• Free wheeling diodes in inductive load circuits
• Polarity protection applications

Diode Arrays Procurement Notes

This component is officially obsolete and has been discontinued by Diodes Incorporated. No exact alternate part number exists within the manufacturer's portfolio. Verification of availability should focus on identifying equivalent specifications from other manufacturers or utilizing alternative packages such as the standard MBR2045 series if pin compatibility allows.

Diode Arrays Selection Notes

Selection requires evaluating the specific requirement for an electrically isolated heatsink tab, which distinguishes this variant from standard TO-220AB packages. Designers must account for the 45V reverse voltage rating and the 10A per-leg current limit when calculating thermal dissipation. The isolation voltage of 2000VAC between terminals and the heatsink is critical for safety compliance in grounded chassis designs.

Diode Arrays Part Context

The MBR2045CTP belongs to the MBR2045 family of Schottky barrier rectifiers produced by Diodes Incorporated. While the broader family remains active in various packages like TO-220AB and TO-220F, the specific ITO-220S variant with the isolated tab has been removed from production. This product line targets general-purpose rectification in low voltage, high frequency inverters.

Diode Arrays Replacement Considerations

No exact alternate part number is provided by the manufacturer. Engineers should consider the MBR2045 available in other packages or equivalent Schottky rectifiers from other vendors that match the 45V/20A specification and provide necessary isolation requirements.
