MBRB3045CTTRL

Diode Arrays Overview

The MBRB3045CTTRL is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It features two silicon diodes in a TO-263AB (D²PAK) package with the cathode connected to the heatsink tab. The device supports a maximum repetitive peak reverse voltage of 45 V and a total maximum average forward rectified current of 30 A, rated at 15 A per diode. Key electrical parameters include a maximum instantaneous forward voltage of 0.76 V at 30 A and a peak forward surge current capability of 200 A per diode.

Diode Arrays Feature Summary

• Guardring structure provides protection against overvoltage transients
• Low forward voltage drop contributes to high efficiency and reduced power losses
• High forward surge capability ensures robustness during transient load conditions
• High frequency operation suitable for switching applications

Diode Arrays Applications

• Freewheeling diodes in low voltage circuits
• Polarity protection in electronic systems
• DC-to-DC converters
• Rectifiers in switching mode power supplies

Diode Arrays Procurement Notes

Verify that the ordering suffix matches the required packaging configuration, as standard tubes differ from tape reels. Confirm compliance requirements such as RoHS or AEC-Q101 qualification if applicable to your specific design constraints. Ensure thermal management aligns with the specified junction temperature limits and thermal resistance values provided in the datasheet.

Diode Arrays Selection Notes

Select this component for designs requiring a common-cathode configuration with a 45 V blocking voltage. The TO-263AB package facilitates surface-mount mounting while allowing direct connection to a heatsink via the cathode tab. Consider the 15 A per-diode rating when sizing the thermal solution for continuous operation.

Diode Arrays Part Context

This part belongs to the MBR(F,B)3035CT & MBR(F,B)3045CT series from Vishay General Semiconductor. The 'B' designation indicates the TO-263AB surface-mount package variant. The series includes complementary models with different voltage ratings and package types, such as the through-hole MBR3045CT and isolated MBRF3045CT.

Diode Arrays Replacement Considerations

Cross-reference with MBRB3035CT for lower voltage applications within the same package family. Verify pinout compatibility and thermal characteristics when substituting with other manufacturers' dual Schottky rectifiers.
