MBRB1545CT

Diode Arrays Overview

The MBRB1545CT is a SWITCHMODE Power Rectifier utilizing Schottky Barrier technology with platinum barrier metal. It features a center-tap configuration in a D2PAK surface mount package (CASE 418B). The device supports an average rectified forward current of 7.5 A per leg and a peak repetitive reverse voltage of 45 V. It operates at junction temperatures up to 175°C, offering low forward voltage drop and high efficiency for switching power supply applications.

Diode Arrays Feature Summary

• Employs Schottky Barrier principle with platinum barrier metal for reliable operation.
• Features a center-tap configuration suitable for dual common cathode setups.
• Includes guardring design for enhanced stress protection and ruggedness.
• Utilizes short heatsink tab manufacturing rather than sheared tabs.

Diode Arrays Applications

• Switching power supplies
• Converters
• Free-wheeling diodes
• Reverse battery protection

Diode Arrays Procurement Notes

Verify the specific ordering suffix when purchasing. Suffixes such as 'T4' indicate tape and reel packaging, while 'G' denotes lead-free status. Confirm the required package quantity matches the application needs, as options include rails or reels. Ensure the selected variant aligns with the intended assembly process and environmental compliance requirements.

Diode Arrays Selection Notes

Select this component for designs requiring high-frequency operation and low forward voltage drop. The D2PAK package provides thermal performance comparable to TO-220 while enabling surface mount integration. Consider the 175°C junction temperature rating for high-temperature environments. Verify that the 45V reverse voltage rating meets the circuit's peak repetitive reverse voltage requirements.

Diode Arrays Part Context

This part belongs to the MBRB15..CT series of SWITCHMODE Power Rectifiers manufactured by onsemi. These devices are designed for low reverse leakage at high temperatures. The series utilizes proprietary barrier technology to ensure reliability up to 150°C junction temperature, though this specific model supports higher operating limits.

Diode Arrays Replacement Considerations

MBRB1545CTT4G is a verified lead-free replacement variant within the same product family. Both share identical electrical characteristics and pinout configurations. Ensure the replacement matches the required packaging format if tape and reel is necessary for automated assembly.
