MBRB2545CT-E3/81

Diode Arrays Overview

The MBRB2545CT-E3/81 is a dual Schottky barrier rectifier manufactured by Vishay General Semiconductor. It features a common cathode configuration with two independent elements housed in a TO-263AB (D2PAK) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 45V and an average forward rectified current of 15A per element. Key electrical parameters include a maximum non-repetitive peak forward surge current of 150A, a typical forward voltage drop of 840mV at rated current, and a maximum reverse leakage current of 100µA. It operates within a junction temperature range of -65°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the exact tape-and-reel quantity specified in the procurement documentation. Cross-reference the component marking with the manufacturer's identification guide to prevent counterfeit substitution during assembly.

Diode Arrays Selection Notes

Select this component when a low-loss, high-current solution is required for 45V systems. The TO-263AB package provides superior thermal management compared to smaller SMD packages. Consider the 15A rating per leg for balanced load distribution. Verify that the circuit design accommodates the 150A surge capability for inrush conditions without exceeding thermal limits.

Diode Arrays Part Context

This part belongs to Vishay's MBRB series of SwitchMode Power Rectifiers designed for surface-mount applications. The series utilizes advanced Schottky technology to achieve high efficiency in low-voltage, high-frequency power supplies. The E3 suffix indicates lead-free termination and compliance with RoHS directives, aligning with modern environmental standards for electronic manufacturing.

Diode Arrays Replacement Considerations

Publicly confirmed substitute part numbers include MBRB2545CT-E3/45 and MBRB2545CTT4. Verify that alternative sources maintain identical pin configurations and thermal resistance values. Confirm that the replacement device meets the same 45V reverse voltage and 15A current ratings to ensure circuit integrity.
