MB20H90CTHE3_A/I

Diode Arrays Overview

The MB20H90CTHE3_A/I is a dual common-cathode Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 90 V and an average forward rectified current of 10 A per diode element. The device utilizes TO-263AB (D2PAK) surface-mount packaging with the case connected to the cathode. Key electrical characteristics include a maximum DC forward voltage of 800 mV at 10 A and a maximum non-repetitive peak forward surge current of 250 A. The junction temperature range spans from -65°C to 150°C, ensuring reliable operation in high-efficiency power conversion applications.

Diode Arrays Procurement Notes

Verify the specific suffix _A/I against the official Vishay datasheet to confirm package dimensions and marking details. Ensure the procurement source provides valid traceability documentation for automotive or industrial grade requirements. Cross-reference the part number with the latest Vishay release notes to confirm component status and any potential obsolescence notices prior to finalizing orders.

Diode Arrays Selection Notes

Select this component when a dual Schottky arrangement is required for currents up to 10 A with a 90 V reverse voltage rating. The TO-263AB package offers superior thermal dissipation compared to smaller surface-mount options. Consider the 250 A surge capability for inrush protection scenarios. Evaluate the 800 mV forward voltage drop against system efficiency targets to ensure optimal performance in low-voltage output designs.

Diode Arrays Part Context

This device belongs to the MBRH series of high-current Schottky rectifiers designed for efficiency. It serves as a robust alternative to standard PN-junction diodes in applications where reverse recovery charge causes excessive heating. The common-cathode topology allows for compact circuit layouts in synchronous rectification or full-wave rectification topologies within medium-power industrial and consumer electronics systems.

Diode Arrays Replacement Considerations

Direct replacements must match the 90 V rating, 10 A current capacity, and dual common-cathode configuration. Verify that substitute components utilize Schottky technology to maintain equivalent forward voltage and switching speed characteristics. Ensure the replacement package matches the TO-263AB footprint and thermal pad requirements for proper PCB integration.
