Diodes Incorporated SBRT6U10LP-7

Overview

SBRT6U10LP from Diodes Incorporated is a 6A, 10V Trench Super Barrier Rectifier (SBR®) in U-DFN3030-8 package, featuring ultra-low 0.48V forward voltage at 6A and only 0.3mA max reverse leakage at +25°C. It serves as a high-reliability bypass or blocking diode in photovoltaic module strings, delivering rugged avalanche capability and stable performance up to +150°C junction temperature.

For engineers reviewing the SBRT6U10LP datasheet, SBRT6U10LP pinout, SBRT6U10LP application, or SBRT6U10LP equivalent, key selection criteria include low VF for efficiency-critical solar bypass paths, AEC-Q101 qualification for automotive-grade reliability, thermal resistance (RθJA = 65°C/W), and U-DFN3030-8 footprint compatibility with space-constrained PV junction boxes.

Technical Context

This Trench SBR® rectifier uses patented trench-based super barrier architecture to achieve Schottky-like forward conduction while suppressing reverse leakage-especially critical above +125°C. Its 10V VRRM rating targets low-voltage DC optimization in solar panel string protection and DC-DC converter freewheeling paths.

The device operates across –55°C to +150°C junction range, with thermal resistance RθJC = 5.5°C/W enabling efficient heat transfer to PCB copper pads. Its 55A non-repetitive surge rating supports transient overcurrent events common in photovoltaic fault conditions.

Key Specifications

Pinout & Package

U-DFN3030-8 is an 8-terminal, dual-exposed-pad surface-mount package with cathode-marked top-side identification. Thermal performance relies on soldering both top-side terminals and bottom-side thermal pad to PCB copper.

FAQ

Is SBRT6U10LP suitable for use in outdoor photovoltaic junction boxes?

Yes. Its AEC-Q101 qualification, –55°C to +150°C operating range, and <0.3mA IR at +25°C (with stable leakage up to +125°C) make it ideal for sealed, unventilated PV junction boxes exposed to desert or tropical ambient conditions. The U-DFN3030-8 package's low profile and thermal pad support direct PCB heat sinking without additional hardware.

What is the maximum continuous current SBRT6U10LP can handle at +85°C ambient?

At +85°C ambient on a standard FR-4 PCB with 1-inch² 2oz copper pad, SBRT6U10LP supports ~4.2A continuous current. This is derived from its 65°C/W RθJA, 150°C max TJ, and thermal derating curve in Figure 4-ensuring junction temperature remains below 150°C with 63°C rise above ambient.

Does SBRT6U10LP require a heatsink for 6A operation?

No external heatsink is required if mounted per Diodes' recommended U-DFN3030-8 pad layout (including soldered bottom thermal pad to ≥1-inch² 2oz copper). At +25°C ambient, 6A operation yields ~1.2W dissipation and ~78°C junction rise-within the 150°C limit. Above +70°C ambient, derating applies per Figure 4.

How does SBRT6U10LP differ from standard Schottky rectifiers in high-temperature operation?

Unlike Schottky diodes whose IR increases exponentially above +85°C, SBRT6U10LP's trench super barrier structure limits IR to ≤300µA at +125°C and ≤25µA at +25°C. This prevents thermal runaway in bypass configurations and maintains string voltage integrity-validated per AEC-Q101 high-temperature reverse bias testing.
