MBR2090CT

Diode Arrays Overview

The onsemi MBR2090CT is a Switch-mode Power Rectifier utilizing the Schottky Barrier principle with platinum barrier metal. It features a dual common cathode configuration within a TO-220 package (Case 221A). Each diode leg supports an average rectified forward current of 10 A and a peak repetitive reverse voltage of 90 V. The device operates at junction temperatures up to 175°C, offering low forward voltage drop and high surge capacity.

Diode Arrays Applications

• Low voltage, high frequency inverters
• Free wheeling applications
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix when sourcing components. The 'G' suffix indicates Pb-Free and RoHS compliance, whereas non-G variants may differ in material composition. Confirm the exact package style and shipping quantity requirements against the manufacturer's current documentation to ensure compatibility with assembly processes.

Diode Arrays Selection Notes

Select this component for designs requiring high efficiency and low power loss in switch-mode applications. Ensure thermal management accounts for the specified junction-to-case thermal resistance. Verify that the operating ambient temperature allows for proper current derating as defined in the datasheet curves to maintain reliability within the 175°C maximum junction limit.

Diode Arrays Part Context

This device belongs to the MBR2080CT/MBR2090CT/MBR20100CT series of 20 Ampere Schottky rectifiers. The series shares identical mechanical characteristics and general electrical performance profiles, differentiated primarily by their peak repetitive reverse voltage ratings of 80 V, 90 V, and 100 V respectively.

Diode Arrays Replacement Considerations

Cross-reference with MBR2090CTG for verified Pb-Free alternatives. Other manufacturers producing equivalent 20 A, 90 V Schottky rectifiers in TO-220 packages should be evaluated based on matching thermal resistance and forward voltage specifications.
