MBRB20200CTT4G

Diode Arrays Overview

The MBRB20200CTT4G is a dual Schottky barrier rectifier manufactured by onsemi, housed in a TO-263 (D2PAK) surface-mount package. It features a common cathode configuration with two internal diodes. Key electrical specifications include a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 20 A per diode. The device exhibits a low forward voltage drop of approximately 1 V at 10 A and a non-repetitive peak forward surge current rating of 150 A. It operates within a junction temperature range of -65°C to 150°C.

Diode Arrays Feature Summary

• Utilizes platinum barrier metal technology for high-frequency switching performance up to 5 MHz.
• Incorporates guardring structure for enhanced stress protection and high dv/dt capability.
• Dual diode construction allows parallel operation when terminals are connected for full rating.

Diode Arrays Applications

• High frequency switching power supplies
• DC-DC converters with outputs up to 48 V
• Free-wheeling rectification in low voltage, high frequency circuits

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Ensure the component meets required automotive or industrial standards if applicable. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling and low forward voltage drop in compact surface-mount designs. The TO-263 package provides robust thermal performance for power dissipation. Consider the 200 V blocking voltage and 20 A current rating to ensure adequate margin for the target circuit's peak operating conditions.

Diode Arrays Part Context

This device belongs to onsemi's SWITCHMODE Power Rectifier series, designed specifically for efficient power conversion. The MBRB20200CTT4G variant utilizes the T4G suffix, indicating a lead-free, halogen-free package compliant with RoHS directives. It serves as a modern replacement for older through-hole rectifiers in space-constrained PCB layouts.

Diode Arrays Replacement Considerations

The MBRB20200CTH-TP from Micro Commercial Components is documented as a similar alternative. Verify pinout compatibility and thermal characteristics when substituting. Ensure the replacement meets the same 200 V and 20 A ratings for direct interchangeability in existing designs.
