MBRB1545CTT4

Diode Arrays Overview

The MBRB1545CTT4 is a Schottky barrier rectifier manufactured by onsemi, utilizing platinum barrier metal technology. It features a dual common cathode configuration housed in a D2PAK surface mount package (Case 418B). The device supports a peak repetitive reverse voltage of 45 V and an average rectified forward current of 7.5 A per leg. Electrical characteristics include a maximum instantaneous forward voltage of 0.84 V at 15 A and 25°C junction temperature. It operates within a junction temperature range of -65°C to +175°C and withstands non-repetitive peak surge currents up to 150 A.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and availability status. The datasheet indicates that certain variants within this product family may be discontinued or subject to change without notice. Confirm lead times and production lifecycle status directly with authorized distributors or the manufacturer before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage drops and high-frequency operation. Ensure the thermal management design accounts for the junction-to-ambient resistance when operating without a dedicated heatsink. Verify that the circuit's peak reverse voltage does not exceed the 45 V rating and that surge current capabilities align with the system's transient requirements.

Diode Arrays Part Context

This device belongs to the MBRB1545CT series of Schottky power rectifiers designed for surface mount applications. It shares functional similarities with through-hole counterparts but offers compact footprint advantages. The D2PAK package provides robust mechanical stability and efficient heat dissipation compared to smaller surface mount packages, making it suitable for medium-power density designs.
