MBRB1550CTHE3/45

Diode Arrays Overview

The MBRB1550CTHE3/45 is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes the TO-263AB (D2PAK) surface-mount package and is designated as high reliability grade with AEC-Q101 qualification. The device supports a maximum repetitive peak reverse voltage of 50 V and provides a total maximum average forward rectified current of 15 A, distributed as 7.5 A per diode at a case temperature of 105 °C. Electrical characteristics include a maximum instantaneous forward voltage of 0.72 V at 7.5 A and 0.75 V at 15 A when measured at a case temperature of 25 °C. Peak forward surge current capability is rated at 150 A per diode under an 8.3 ms single half-sine-wave condition.

Diode Arrays Procurement Notes

Verify that the specific ordering suffix matches the required packaging format, such as tube or tape reel quantities. Confirm the HE3 designation indicates the high reliability automotive grade variant rather than the standard consumer grade E3 version. Ensure the component meets the necessary environmental compliance standards for the intended deployment environment before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component for designs requiring a dual common-cathode configuration within a compact surface-mount footprint. The 50 V rating and 15 A total current capacity make it appropriate for low-voltage, high-current synchronous rectification stages. Evaluate the thermal management requirements to ensure the case temperature remains within limits for the specified current derating curves during continuous operation.

Diode Arrays FAQ

What does the HE3 suffix indicate for this component?

The HE3 suffix denotes the high reliability grade, which is qualified to AEC-Q101 standards and meets stricter JESD 201 class 2 whisker test requirements compared to the standard consumer grade.

How is the forward current distributed in this dual diode configuration?

The device contains two independent diodes within a single package configured as a common cathode, with each diode rated for a maximum average forward current of 7.5 A.

What is the maximum non-repetitive peak forward surge current?

Each diode can withstand a peak forward surge current of 150 A for a duration of 8.3 ms on a single half-sine wave superimposed on the rated load.
