Product details
Overview
SBRT05U10LPQ-7B from Diodes Incorporated is a 10 V, 0.5 A trench super barrier rectifier (SBR®) in X1-DFN1006-2 package, featuring ultra-low VF (0.39 V max at 0.5 A), 180 µA IR max at 10 V/25°C, and AEC-Q101 qualification. It serves as a high-efficiency freewheeling or polarity protection diode in space-constrained DC-DC converters and automotive SMPS.
For engineers reviewing the SBRT05U10LPQ-7B datasheet, SBRT05U10LPQ-7B pinout, SBRT05U10LPQ-7B application, or SBRT05U10LPQ-7B equivalent, key selection criteria include forward voltage drop at 0.5 A, reverse leakage at 125°C, thermal resistance (236 °C/W), junction temperature rating (+150°C), and AEC-Q101 compliance for automotive-grade reliability.
Technical Context
This SBR device uses patented trench-based super barrier technology to achieve lower forward voltage than Schottky diodes while maintaining superior reverse leakage stability-especially critical above 100°C. Its soft, fast switching behavior minimizes EMI in high-frequency DC-DC topologies.
The X1-DFN1006-2 package enables high power density with low thermal resistance (RθJA = 236 °C/W on FR-4) and supports automated placement. The cathode dot marking and NiPdAu-plated terminals ensure reliable solderability per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 10 V - Maximum repetitive reverse blocking voltage; defines safe operating range in polarity protection and flyback clamp circuits. |
| IO | 0.5 A - Average rectified output current; supports continuous operation in low-power DC-DC stages up to +125°C ambient. |
| VF Max | 0.39 V @ 0.5 A - Ultra-low forward drop reduces conduction loss by >30% vs. standard Schottkys, improving efficiency in battery-powered systems. |
| IR Max | 180 µA @ 10 V, 25°C - Low leakage ensures minimal standby power loss; remains <15 µA at 125°C for thermally stable operation. |
| TJ Max | +150°C - Rated junction temperature enables use in under-hood automotive modules without derating at elevated ambient. |
| RθJA | 236 °C/W - Thermal resistance on FR-4 PCB with minimum pad layout; informs heatsinking requirements for sustained 0.5 A load. |
Pinout & Package
Package: X1-DFN1006-2 - 1.0 mm × 0.6 mm, 0.25 mm nominal height, lead-free, halogen-free, RoHS-compliant surface-mount package with exposed cathode pad and cathode dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to input/source side in polarity protection; requires low-inductance trace routing for fast-switching integrity. |
| Cathode | Current exit terminal during forward conduction; marked with dot | Exposed metal pad on bottom surface provides primary thermal path and electrical return; must be soldered to copper pour for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | VF = 0.34 V typ @ 0.5 A, 25°C - directly reduces I²R losses in portable and automotive power rails. |
| Soft, fast switching | No reverse recovery tail current - eliminates switching spikes and EMI in synchronous buck freewheel paths. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics - supports PPAP documentation. |
| +150°C operating junction | Enables deployment in high-temp zones (e.g., near power MOSFETs or in sealed enclosures) without thermal derating. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT05U10LPSQ-7B | Same die, but in X1-DFN1206-2 package (1.2 mm × 0.6 mm); 10% larger footprint, 10% lower RθJA. | Better thermal performance in higher-current or less-ventilated layouts; not suitable for ultra-dense designs. | Select when thermal margin is prioritized over board area; identical electrical specs and AEC-Q101 qualification. |
| SBRT05U20LPSQ-7B | 20 V VRRM, same IO/VF/IR; slightly higher capacitance (12 pF vs. 10 pF). | Supports 15 V nominal inputs (e.g., industrial 12 V ±20%); trades margin for wider voltage coverage. | Choose where system input may exceed 12 V transiently; verify reverse leakage remains acceptable at target operating temperature. |
Compared with SBRT05U10LPSQ-7B, the -7B variant offers tighter board area utilization; versus SBRT05U20LPSQ-7B, it delivers lower parasitic capacitance and optimized leakage for 10 V-rail applications-making it the preferred choice for space- and efficiency-critical 12 V automotive and portable designs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBRT05U10LPQ-7B is rated for continuous operation up to +150°C junction temperature. Derating begins at +25°C ambient per Figure 3: IO drops linearly to zero at +150°C ambient on FR-4 with minimum pad layout. At +125°C ambient, the device supports ~0.25 A average current.
Is this diode suitable for synchronous rectification replacement?
No-SBRT05U10LPQ-7B is a passive unidirectional rectifier and lacks gate control. However, its soft switching and low VF make it an optimal *asynchronous* replacement for Schottky diodes in flyback, buck, and boost converters where gate drive complexity must be avoided.
Does the X1-DFN1006-2 package require thermal vias under the cathode pad?
Thermal vias are recommended but not mandatory. The datasheet specifies RθJA = 236 °C/W assumes no thermal vias on FR-4. Adding ≥4 x 0.3 mm vias filled with solder beneath the cathode pad can reduce RθJA by 30–40%, enabling full 0.5 A current at higher ambient temperatures.
How does leakage current behave at elevated temperature?
IR increases with temperature: 32 µA typ at 25°C rises to 15 µA max at 125°C (VR = 10 V). This is significantly lower than conventional Schottkys, which often exceed 100 µA at 125°C-making SBRT05U10LPQ-7B suitable for high-temp standby circuits.
