MBRB1535CT

Diode Arrays Overview

The MBRB1535CT is a dual common-cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features two independent anodes sharing a common cathode base, housed in a D2PAK (TO-263) surface-mount package. The device provides a maximum average forward current of 7.5 A per leg and a maximum repetitive peak reverse voltage of 35 V. Key electrical characteristics include a maximum forward voltage drop of 0.84 V at 15 A and 25 °C, and a maximum non-repetitive surge current of 690 A. It operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant and lead-free status. Confirm that the component meets the required Q101 qualification level if intended for automotive use. Ensure thermal management design accounts for the specified thermal resistance values to maintain safe operating junction temperatures.

Diode Arrays Selection Notes

Select this component when a surface-mount dual Schottky configuration with a common cathode is required. The D2PAK package offers lower thermal resistance compared to through-hole alternatives. Consider the 35 V rating for low-voltage applications where minimizing forward voltage drop is critical for efficiency. Verify compatibility with automated pick-and-place equipment due to the surface-mount form factor.

Diode Arrays Part Context

This part belongs to the MBR15..CT series of high-power Schottky rectifiers from Vishay. The series includes variants with different voltage ratings, such as the MBRB1545CT which offers 45 V blocking capability. The 'B' suffix in the part number specifically denotes the D2PAK surface-mount package, distinguishing it from the TO-262 through-hole version designated by '-1'.

Diode Arrays Replacement Considerations

MBRB1545CT: Offers identical current and package specifications but with a higher 45 V reverse voltage rating.
