MBRB2545CT

Diode Arrays Overview

The MBRB2545CT is a dual common cathode Schottky barrier rectifier in a D2PAK surface mount package. It features a platinum barrier metal and center-tap configuration for stress protection. The device supports an average rectified forward current of 30 A total (15 A per leg) and a peak repetitive reverse voltage of 45 V. Key electrical parameters include a maximum instantaneous forward voltage of 0.82 V at 30 A and 25°C, and a non-repetitive peak surge current of 150 A. It operates within a junction temperature range of -65°C to +175°C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix to confirm packaging format. Standard rails contain 50 units, while tape and reel options contain 800 units. Confirm lead-free status if required by assembly specifications. Ensure the selected variant matches the required thermal management capabilities for the target application environment.

Diode Arrays Selection Notes

Select this component for high-efficiency rectification where low conduction losses are critical. The D2PAK package offers a footprint similar to TO-220 but enables surface mount automation. Verify that the 45 V reverse voltage rating exceeds the circuit's peak inverse voltage. Consider the 15 A per-leg current limit when designing parallel paths or calculating thermal dissipation requirements.

Diode Arrays Part Context

This device belongs to onsemi's SWITCHMODE power rectifier series. It utilizes Schottky barrier principles to minimize switching losses compared to standard PN junction diodes. The D2PAK (CASE 418B) package provides robust thermal conductivity through the exposed copper tab, facilitating efficient heat transfer to the PCB or heatsink.

Diode Arrays Replacement Considerations

MBRB2545CTG is the verified lead-free equivalent. MBRB2545CTT4 and MBRB2545CTT4G offer identical electrical performance in tape and reel packaging.
