MBRF890CT

Diode Arrays Overview

The MBRF890CT is a Schottky barrier rectifier from the Taiwan Semiconductor MBRF835CT series, housed in an ITO-220AB package. It features dual common cathode silicon elements with a repetitive peak reverse voltage of 90V and an average forward current rating of 8A. The device supports a surge peak forward current of 150A and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum forward voltage of 0.85V at 4A and a typical junction-to-case thermal resistance of 6°C/W.

Diode Arrays Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to confirm the exact voltage rating and packaging configuration. Ensure that the component selection aligns with the required thermal management specifications and operating temperature ranges defined in the datasheet. Confirm compliance requirements such as RoHS and halogen-free status if applicable to your manufacturing standards.

Diode Arrays Selection Notes

Select this component based on the 90V reverse voltage requirement and 8A continuous current capacity. Consider the thermal resistance and derating curves for high-temperature environments. Verify that the ITO-220AB package fits the mechanical constraints of the design. Evaluate the forward voltage drop impact on overall system efficiency.

Diode Arrays Part Context

This part belongs to the MBRF8xCT series, which includes variants ranging from 35V to 150V reverse voltage. All members share the same 8A forward current rating and ITO-220AB package. The series is designed for general-purpose rectification applications requiring high efficiency and robustness against voltage spikes.

Diode Arrays Replacement Considerations

Direct replacements must match the 90V VRRM, 8A IF, and ITO-220AB package. Check equivalent parts from other manufacturers for compatible forward voltage and thermal characteristics. Ensure pinout compatibility and mounting torque specifications are met.
