Diodes Incorporated SBR12U100P5-13

Overview

SBR12U100P5 from Diodes Incorporated is a 12A, 100V ultra-low-forward-voltage Super Barrier Rectifier in PowerDI5 package, featuring 0.49V VF at 5A/25°C, 150°C junction rating, and soft fast switching for high-efficiency DC-DC output rectification in industrial power supplies.

For engineers reviewing the SBR12U100P5 datasheet, SBR12U100P5 pinout, SBR12U100P5 application, or SBR12U100P5 equivalent, key selection criteria include forward voltage drop at 12A, thermal resistance (RθJL = 3°C/W), leakage current at 125°C, and compatibility with high-temperature PCB layouts using the PowerDI5 leadframe footprint.

Technical Context

This SBR device uses patented Super Barrier Rectifier technology to achieve lower VF than Schottky diodes while maintaining higher reverse voltage capability and superior high-temperature stability. Its 100V VRRM rating and 250A IFSM surge capacity support robust operation in 48V-input SMPS secondary-side rectification.

The PowerDI5 package delivers low thermal resistance (RθJL = 3°C/W) via direct copper leadframe conduction, enabling high-current handling without external heatsinking. Soft recovery minimizes EMI in synchronous rectifier replacement and flyback/foward converter outputs.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, serving industrial, computing, communications, and consumer markets with high-reliability components.

The SBR® Super Barrier Rectifier product line targets high-efficiency, high-temperature power conversion applications where Schottky limitations-leakage, voltage rating, and thermal instability-are unacceptable.

FAQ

What is the maximum allowable lead temperature during reflow soldering?

The SBR12U100P5 is rated for moisture sensitivity level 1 per J-STD-020 and supports standard Pb-free reflow profiles. Peak lead temperature must not exceed 260°C for ≤10 seconds, with ramp rates conforming to IPC/JEDEC J-STD-020. The matte tin finish ensures reliable wetting on OSP- or ENIG-finished PCBs.

Can SBR12U100P5 replace a standard Schottky diode in an existing design?

Yes, provided the PowerDI5 footprint matches and thermal layout accommodates its 3°C/W RθJL. Its 0.49V VF at 5A/25°C typically improves efficiency over 0.6–0.75V Schottkys, but verify leakage at 125°C (0.25 mA) and ensure soft recovery eliminates need for snubbers previously used for hard-switching devices.

Is there an automotive-grade version of this part?

Yes - the SBR12U100P5Q is the AEC-Q101 qualified automotive variant, with identical electrical specs and PowerDI5 packaging, but subjected to extended reliability testing including HTOL, TCT, and ESD per AEC standards. It carries separate qualification documentation and part marking.

How does the PowerDI5 package improve thermal performance over SOD-123 or SMA?

PowerDI5's exposed copper leadframe provides direct thermal conduction from die to PCB, achieving RθJL = 3°C/W - over 5× better than SOD-123 (RθJA ≈ 150°C/W). When soldered to 16 mm² copper, its RθJA drops to 27°C/W, enabling 12A operation without heatsinks where smaller packages would thermally saturate.
