MBRB1550CTHE3/81

Diode Arrays Overview

The MBRB1550CTHE3/81 is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It features a TO-263AB surface-mount package and provides two independent diodes with a maximum average forward current of 7.5 A per diode (15 A total). The device has a maximum repetitive peak reverse voltage of 50 V and supports a peak forward surge current of 150 A. Electrical characteristics include a maximum instantaneous forward voltage of 0.65 V at 7.5 A and a maximum reverse leakage current of 1.0 mA at rated blocking voltage. Operating junction temperature ranges from -65 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The HE3 suffix indicates high reliability grade qualification, while the /81 code specifies tape reel packaging. Confirm RoHS status and moisture sensitivity level prior to procurement to ensure compatibility with assembly processes.

Diode Arrays Selection Notes

Select this component for designs requiring low forward voltage drop and high efficiency in high-frequency environments. Ensure the 50 V reverse voltage rating exceeds the circuit's peak working voltage. Verify thermal management capabilities as the TO-263AB package requires adequate heatsinking to maintain performance within the specified junction temperature range.

Diode Arrays Part Context

This part belongs to the MBR(F,B)15xxCT series of dual common-cathode Schottky barrier rectifiers. The series offers various voltage ratings ranging from 35 V to 60 V. The MBRB variant specifically denotes the TO-263AB surface-mount package configuration, distinguishing it from through-hole options like TO-220AB or ITO-220AB.

Diode Arrays Replacement Considerations

Compatible substitutes within the same family include MBRB1545CTHE3/81 and MBRB1560CTHE3/81. These parts share identical pinouts and mechanical dimensions but differ in maximum repetitive peak reverse voltage ratings.
