MBR3090CT

Diode Arrays Overview

The MBR3090CT is a dual common cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor. It features a TO-220AB package with two silicon elements. The device supports a maximum average forward current of 30 A and a repetitive peak reverse voltage of 90 V. Peak forward surge current capability reaches 200 A under an 8.3 ms single half-sine wave condition. The junction temperature range spans from -55°C to +150°C, with a typical junction-to-case thermal resistance of 1.5 °C/W.

Diode Arrays Feature Summary

• Guard ring structure provides protection against overvoltage conditions.
• High efficiency operation achieved through low power loss characteristics.
• Matte tin plated leads ensure solderability per J-STD-002 standards.

Diode Arrays Applications

• Switching mode power supplies
• Adapters
• DC to DC converters

Diode Arrays Procurement Notes

Verify the specific ordering code suffix when sourcing components. The standard 'MBR3090CT' designation indicates non-AEC-Q101 qualification. Select the 'H' suffix variant only if automotive-grade reliability is required. Confirm the package type matches the intended PCB footprint before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component for applications requiring high-frequency rectification with low forward voltage drop. Ensure the thermal design accommodates the specified junction-to-case thermal resistance. Verify that the circuit's peak reverse voltage does not exceed the 90 V rating. Consider the 200 A surge current limit during inrush events.

Diode Arrays Part Context

This part belongs to the MBR30xCT series, which includes variants ranging from 35 V to 150 V reverse voltage ratings. All members share the same 30 A current capacity and TO-220AB mechanical form factor. The series utilizes identical die construction and packaging materials across all voltage options.

Diode Arrays Replacement Considerations

Cross-reference other manufacturers offering 30 A, 90 V dual common cathode Schottky rectifiers in TO-220AB packages. Verify pinout compatibility and thermal resistance values match the original design requirements before substitution.

Diode Arrays FAQ

What is the marking code on the MBR3090CT device?

The marking code printed on the device body is MBR3090CT.

Does the MBR3090CT meet automotive qualification standards?
