MBR2090CTH

Diode Arrays Overview

The MBR2090CTH is a dual common-cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a TO-220AB package with a repetitive peak reverse voltage of 90 V and a maximum average forward current of 20 A. The device supports a peak forward surge current of 150 A and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum forward voltage of 0.85 V at 10 A and 0.95 V at 20 A, both measured at 25°C. Reverse leakage current is limited to 100 µA at rated voltage and 25°C. The component is AEC-Q101 qualified.

Diode Arrays Feature Summary

• Guard ring structure provides protection against overvoltage stress
• Halogen-free construction compliant with IEC 61249-2-21 standards
• Matte tin plated leads ensure solderability per J-STD-002 specifications

Diode Arrays Applications

• Switching mode power supplies (SMPS)
• Power adapters
• DC to DC converters

Diode Arrays Procurement Notes

Verify the specific ordering code includes the 'H' suffix to confirm AEC-Q101 automotive qualification status. Confirm the package type matches the required TO-220AB form factor for the intended circuit board layout. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values under expected operating loads.

Diode Arrays Selection Notes

Select this component when a 90 V blocking capability is required in a dual common-cathode configuration. The TO-220AB package facilitates heatsink mounting for high-current applications. Verify that the system's peak reverse voltage does not exceed the 90 V rating and that the continuous forward current remains within the 20 A limit.

Diode Arrays Part Context

This part belongs to the MBR2035CT through MBR20200CT series from Taiwan Semiconductor. The series offers various voltage ratings ranging from 35 V to 200 V while maintaining a consistent 20 A current capacity. The 'H' suffix specifically denotes AEC-Q101 qualification for automotive reliability requirements.

Diode Arrays Replacement Considerations

Other members of the MBR20xCT series may serve as substitutes if voltage ratings align with circuit requirements. Cross-manufacturer equivalents must match the TO-220AB package dimensions and electrical parameters precisely.

Diode Arrays FAQ

What is the significance of the 'H' suffix in the MBR2090CTH part number?

The 'H' suffix indicates that the device is qualified according to the AEC-Q101 standard for automotive applications.
