Diodes Incorporated SBR3U60SLDQ-13

Overview

SBR3U60SLDQ-13 from Diodes Incorporated is a dual isolated 3.0A, 60V Super Barrier Rectifier (SBR®) in a PowerDI5060-8 (Type D) package, featuring 0.60V max forward voltage at 3.0A and 0.10mA max reverse leakage at 60V/25°C. It delivers rugged avalanche capability (90mJ EAS), AEC-Q101 qualification, and low thermal resistance (RθJC = 20°C/W), making it suitable for automotive bridge and reverse polarity protection circuits.

For engineers reviewing the SBR3U60SLDQ-13 datasheet, SBR3U60SLDQ-13 pinout, SBR3U60SLDQ-13 application, or SBR3U60SLDQ-13 equivalent, key selection criteria include high-temperature reverse leakage stability (≤15mA at 125°C), dual-diode isolation integrity, PowerDI5060-8 thermal performance on FR-4 PCB, and AEC-Q101 PPAP readiness for automotive power systems.

Technical Context

This device integrates two electrically isolated SBR rectifiers-each rated for 60V VRRM and 3.0A IO-with patented Super Barrier technology enabling lower VF than Schottky diodes while maintaining superior avalanche ruggedness (90mJ EAS). Its construction avoids the thermal runaway limitation of Schottkys, supporting stable operation up to +175°C junction temperature.

The PowerDI5060-8 (Type D) package provides dual-diode isolation via internal die separation and shared heat slug, with NiPdAu-plated terminals ensuring solderability and corrosion resistance. Thermal design leverages RθJC = 20°C/W for direct heatsink coupling and RθJA = 70°C/W on optimized 2oz copper layouts.

FAQ

What is the maximum junction temperature and how does it affect continuous current rating?

The SBR3U60SLDQ-13 has a TJ range of –55°C to +175°C. At +175°C junction, its IO derates to approximately 1.3A (per Figure 4). This high-TJ capability allows operation in under-hood environments without forced cooling, unlike Schottky diodes that typically fail above +150°C due to thermal runaway.

How does the PowerDI5060-8 (Type D) package improve thermal performance over SO-8 or TO-252?

The PowerDI5060-8 features an exposed thermal pad (pins 5–8) with RθJC = 20°C/W-nearly 2× better than SO-8 (RθJC ≈ 40°C/W). Its low-profile design (1.1mm max height) and NiPdAu plating ensure reliable reflow soldering and efficient heat transfer to inner-layer copper planes on standard FR-4 PCBs.

Is the dual-diode isolation sufficient for use in split-rail power supplies?

Yes-the two diodes are fully electrically isolated (no internal connection between anodes or cathodes), verified by >1000V inter-diode isolation test in AEC-Q101 stress screening. This enables independent biasing in ±12V or ±5V systems without crosstalk or latch-up risk.

Does the SBR3U60SLDQ-13 require derating for capacitive loads?

Yes-per datasheet Note: "For capacitance load, derate current by 20%." At full 3.0A rated IO, capacitive input filters demand reduced RMS current to avoid IFSM overshoot during cold-start inrush. Use 2.4A maximum for designs with >1000µF bulk capacitance on the output side.
