MBRF850CT

Diode Arrays Overview

The MBRF850CT is an 8A, 50V Schottky Barrier Rectifier from the Taiwan Semiconductor MBRF835CT series. It features a dual-die common cathode configuration in an ITO-220AB package. Key electrical parameters include a maximum repetitive peak reverse voltage of 50V, a forward current rating of 8A, and a surge peak forward current of 150A. The typical junction-to-case thermal resistance is 6°C/W, with a maximum operating junction temperature of 150°C.

Diode Arrays Feature Summary

• Guard ring structure provides overvoltage protection for enhanced reliability.
• Metal silicon junction design ensures majority carrier conduction for low power loss.
• High surge current capability supports demanding transient loads.

Diode Arrays Applications

• Switching mode power supplies (SMPS)
• DC to DC converters
• Adapters

Diode Arrays Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details and qualification status. The standard 'MBRF8xCT' designation indicates tube packing, while the 'H' suffix denotes AEC-Q101 automotive qualification. Ensure the selected variant matches the required voltage and environmental standards for the intended application.

Diode Arrays Selection Notes

Select this component based on the 50V reverse voltage requirement and 8A continuous forward current capacity. Consider the 6°C/W thermal resistance for heat dissipation calculations in the target enclosure. Verify that the ITO-220AB flange mount form factor fits the mechanical constraints of the assembly.

Diode Arrays Part Context

This device belongs to the MBRF835CT through MBRF8150CT product family, which shares identical physical dimensions and electrical characteristics except for the breakdown voltage. The series utilizes a unified ITO-220AB case and dual-die architecture to provide standardized mounting solutions across various voltage ratings.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBRF845CT (45V) and MBRF860CT (60V), provided the system voltage headroom accommodates the difference. Cross-manufacturer replacements must match the 8A current rating, 50V minimum reverse voltage, and ITO-220AB footprint.

Diode Arrays FAQ

Is the MBRF850CT qualified for automotive applications?

Standard versions are not automatically automotive qualified. Only units with the 'H' suffix in the ordering code (e.g., MBRF850CTH) meet the AEC-Q101 qualification requirements.

What is the maximum non-repetitive surge current?

The device can withstand a peak forward surge current of 150A for an 8.3ms single half-sine wave superimposed on rated load.
