Product details
Overview
SBR4U130LP-7 from Diodes Incorporated is a 4A, 130V ultra-low VF super barrier rectifier in U-DFN3030-8 package, designed for high-efficiency DC/DC conversion and secondary-side synchronous rectification in compact power supplies. It delivers 0.55V forward voltage at 4A/125°C, supports 150°C junction operation, and features soft fast switching with 40A non-repetitive surge capability.
For engineers reviewing the SBR4U130LP-7 datasheet, SBR4U130LP-7 pinout, SBR4U130LP-7 application, or SBR4U130LP-7 equivalent, key selection criteria include forward voltage at elevated temperature, reverse leakage at 130V/125°C, thermal resistance on FR-4 (180°C/W), avalanche ruggedness, and compatibility with space-constrained U-DFN layouts.
Technical Context
This device implements patented Super Barrier Rectifier (SBR®) technology to achieve lower forward voltage than Schottky diodes while maintaining higher reverse blocking capability and superior avalanche energy handling. Its soft recovery minimizes EMI in high-frequency switching converters.
The U-DFN3030-8 package uses NiPdAu-plated copper lead frame and is rated for moisture sensitivity Level 1. Thermal performance depends on PCB layout: RθJA is 55°C/W on double-sided 140mm² polyimide and 180°C/W on standard 1"×1" FR-4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 130 V - Maximum repetitive reverse voltage; sets upper limit for DC blocking in 12–48V output rails |
| IF(AV) | 4 A - Average forward current rating; defines continuous conduction capability in buck or flyback secondary side |
| VF @ 4A, 125°C | 0.55 V - Confirmed low conduction loss at full load and high ambient; reduces heat generation in sealed enclosures |
| IR @ 130V, 125°C | 2.5 mA - Reverse leakage under worst-case thermal/reverse bias; impacts standby power in always-on systems |
| IFSM | 40 A - Non-repetitive surge rating; withstands inrush and transient overloads without failure |
| TJ max | +150°C - Maximum junction temperature; enables operation in automotive under-hood or industrial high-temp environments |
| RθJA (FR-4) | 180 °C/W - Thermal resistance on standard PCB; determines required copper area for thermal management |
Pinout & Package
Package: U-DFN3030-8 - 3.0 mm × 3.0 mm × 0.6 mm body, 8-terminal exposed-pad package with dual anode/cathode configuration optimized for low-inductance, high-current routing and thermal dissipation via bottom thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Anode (common) | Four parallel anode terminals reduce series resistance and inductance; enable high-current bidirectional conduction paths |
| 5, 6, 7, 8 | Cathode (common) | Four parallel cathode terminals provide symmetric current return and low-impedance thermal path to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high TJ | 0.55 V @ 4A/125°C - Directly lowers conduction loss by ~30% vs. standard Schottky in thermally stressed conditions |
| Soft, fast switching | Controlled reverse recovery with minimal oscillation - Reduces EMI filter component count and layout sensitivity |
| Superior avalanche capability | Rated for repetitive and non-repetitive avalanche events - Eliminates need for external snubbers in inductive load switching |
| +150°C operating junction | Validated operation up to 150°C - Enables use in high-density power modules without derating in ambient >85°C |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - Meets IPC-1752A Tier 2 reporting and EU environmental compliance mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT4U130LP-7 | Same die, identical electrical specs; differs only in marking code (STF → STG) and tape/reel packaging variant | No functional difference; used interchangeably in same PCB footprint and thermal design | Select when sourcing from alternate Diodes production lot or distributor inventory with different date-code traceability |
| PS130L4-13-F | Higher VF (0.72V @ 4A/125°C); 120°C TJ max; TO-277 package with higher RθJA (220°C/W) | Larger footprint, lower thermal performance, less suitable for ultra-compact designs | Choose only if U-DFN assembly capability is unavailable or legacy TO-277 reflow profile must be retained |
Compared with SBRT4U130LP-7, the SBR4U130LP-7 offers identical performance with standardized marking; versus PS130L4-13-F, it delivers 0.17V lower VF, 30°C higher TJ, and 40°C/W better thermal resistance-enabling smaller heatsinks and higher power density.

FAQ
What is the recommended PCB pad layout for SBR4U130LP-7?
The official Diodes U-DFN3030-8 pad layout specifies a 2.59 mm × 2.49 mm stencil opening with 0.39 mm solder mask defined pads and 3.30 mm overall courtyard. A minimum 140 mm² copper pour connected to the thermal pad via ≥6 vias (0.3 mm diameter, 0.6 mm pitch) is required to achieve the 55°C/W RθJA rating on polyimide substrates.
Does SBR4U130LP-7 require a gate driver or control signal?
No. SBR4U130LP-7 is a passive uncontrolled rectifier and operates solely based on forward bias polarity-no gate drive, timing signal, or external control is needed. It functions autonomously like a diode but with superior VF/TJ and avalanche characteristics compared to standard Schottky devices.
Can SBR4U130LP-7 replace a standard Schottky diode in existing designs?
Yes, with validation. Its pin-compatible U-DFN3030-8 footprint allows drop-in replacement of Schottky diodes like SBM4130CT or PSD1045, but thermal and EMI performance improvements must be verified. Layout changes may be needed to fully exploit its low RθJA and soft switching behavior.
What is the meaning of "SBR®" in the part number?
"SBR®" stands for Super Barrier Rectifier-a proprietary Diodes Incorporated technology that combines a Schottky-like metal-semiconductor junction with a tailored barrier layer to achieve lower forward voltage than conventional Schottky diodes while supporting higher reverse voltage and robust avalanche capability-distinct from both standard Schottky and PN junction rectifiers.
