MBR2090CT-Y

Diode Arrays Overview

The MBR2090CT-Y is a dual common cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor. It features a TO-220AB package with a maximum average forward rectified current (IF) of 20 A and a repetitive peak reverse voltage (VRRM) of 90 V. The device supports a peak forward surge current (IFSM) of 150 A and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a maximum instantaneous 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.

Diode Arrays Procurement Notes

Verify the specific ordering code matches the required voltage rating within the MBR20xCT-Y series. Confirm the packing configuration corresponds to the standard tube quantity specified in the manufacturer's documentation. Ensure compliance requirements such as halogen-free status are validated against project specifications before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component for applications requiring a 90 V blocking voltage and 20 A continuous current handling capability. Consider the thermal resistance characteristics when designing heat dissipation solutions for the TO-220AB package. Evaluate the forward voltage drop at expected operating currents to ensure system efficiency targets are met under various load conditions.

Diode Arrays Part Context

This part belongs to the MBR2035CT-Y through MBR20200CT-Y series from Taiwan Semiconductor. The series offers a range of voltage ratings from 35 V to 200 V while maintaining a consistent 20 A current rating and TO-220AB mechanical footprint. This allows for standardized board layouts across different voltage requirements within the same product family.

Diode Arrays Replacement Considerations

Other devices within the MBR20xCT-Y series may serve as substitutes if voltage ratings align with circuit requirements. Cross-manufacturer replacements must be verified for pinout compatibility, thermal performance, and electrical parameters to ensure functional equivalence without redesigning the host application.
