Product details
Overview
SBR02U100LPQ-7 from Diodes Incorporated is a 100 V, 0.25 A surface-mount Super Barrier Rectifier (SBR®) with ultra-low forward voltage (0.72 V @ 200 mA, +25°C), soft fast switching (3.6 ns reverse recovery), and AEC-Q101 qualification for automotive power rails. It serves as a low-loss blocking diode in DC-DC converter outputs and low-voltage AC-DC rectification stages where thermal efficiency and reliability at +150°C junction temperature are critical.
For engineers reviewing the SBR02U100LPQ-7 datasheet, SBR02U100LPQ-7 pinout, SBR02U100LPQ-7 application, or SBR02U100LPQ-7 equivalent, key selection criteria include its 0.8 V max VF at 200 mA, 1.0 µA IR at 75 V/+25°C, 5 A non-repetitive surge rating, X1-DFN1006-2 package footprint, and AEC-Q101 qualification status for under-hood electronics.
Technical Context
This Super Barrier Rectifier uses patented SBR® technology to achieve lower forward voltage than Schottky diodes while maintaining superior reverse avalanche ruggedness and higher breakdown voltage than standard Schottkys. Its 100 V VRRM and soft-switching behavior minimize EMI in high-frequency DC-DC converters.
The device operates up to +150°C junction temperature and exhibits only 3.6 ns tRR at IF = 10 mA, enabling efficient operation in compact, thermally constrained automotive and industrial power supplies. Its 80 pF junction capacitance at 0 V supports stable high-speed switching performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Blocks up to 100 V repetitive reverse voltage without breakdown, suitable for 48 V automotive systems with transient margin. |
| IO(AV) | 250 mA - Continuous average forward current rating on FR-4 PCB with minimum pad layout; derate 20% for capacitive loads. |
| VF | 0.72 V @ 200 mA, +25°C - Enables <150 mW conduction loss at rated load, reducing thermal stress in space-constrained layouts. |
| tRR | 3.6 ns - Fast, soft reverse recovery minimizes switching noise and ringing in >1 MHz DC-DC topologies. |
| IR | 1.0 µA @ 75 V, +25°C - Low leakage preserves battery standby time in always-on automotive modules. |
| TJ(max) | +150°C - Rated for under-hood operation without derating in engine control units and body electronics. |
| RθJA | 235 °C/W (polyimide PCB) - Thermal resistance informs heatsinking requirements when operating near maximum IO. |
Pinout & Package
Package: X1-DFN1006-2 - 1.0 mm × 0.6 mm, 0.25 mm nominal height, leadless plastic package with NiPdAu-plated copper leadframe; cathode identified by dot marking on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry terminal | Connected to input/source side of rectification path; requires adequate copper pour for thermal dissipation. |
| Cathode (Pin 2) | Forward current exit / reverse-blocking terminal | Marked with dot; connects to output/load side; must be routed away from sensitive analog nodes due to switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.72 V @ 200 mA ensures <150 mW conduction loss at full rated current, improving system efficiency over standard Schottkys. |
| Soft fast switching | 3.6 ns tRR with controlled di/dt reduces EMI generation and eliminates need for snubbers in 1–3 MHz buck converters. |
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing-enables direct integration into ASIL-B supporting subsystems. |
| +150°C TJ operation | Rated for continuous operation at maximum junction temperature, eliminating thermal derating in high-ambient engine bay applications. |
| Green, halogen-free | <900 ppm Br/Cl, <1000 ppm Sb - meets global environmental compliance mandates without sacrificing electrical performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT02U100LPQ-7 | Same die, but in X2-DFN1006-2 package with enhanced thermal pad; RθJA = 190 °C/W (FR-4). | Better thermal performance in high-power-density designs; requires modified footprint. | Select when board-level thermal resistance exceeds 235 °C/W and layout allows larger thermal pad. |
| RB520S-40T1G | 40 V Schottky; VF = 0.33 V @ 200 mA; no AEC-Q101 qualification; IR = 10 µA @ 30 V. | Limited to ≤24 V systems; unsuitable for automotive transients or high-temp environments. | Only for cost-sensitive, non-automotive 5–12 V applications where 100 V rating is unnecessary. |
Compared with SBRT02U100LPQ-7, this part trades thermal performance for smaller footprint; versus RB520S-40T1G, it delivers higher voltage robustness, lower leakage, and automotive qualification-critical for functional safety-critical power paths.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.
The SBR® Super Barrier Rectifier product line targets high-efficiency, high-reliability power conversion in automotive, industrial, and consumer applications where Schottky limitations in voltage and ruggedness are unacceptable.
FAQ
Is SBR02U100LPQ-7 suitable for synchronous rectification?
No-it is a unidirectional, passive rectifier optimized for low VF and soft switching, not gate-controlled operation. Synchronous rectification requires actively driven MOSFETs with precise timing control. This device replaces Schottkys in non-synchronous flyback or buck secondary-side rectification where simplicity and ruggedness are prioritized over peak efficiency.
What is the meaning of the "LPQ" suffix in SBR02U100LPQ-7?
The "LPQ" denotes Diodes Incorporated's proprietary Super Barrier Rectifier (SBR®) technology in the X1-DFN1006-2 package with green, halogen-free molding compound and NiPdAu plating. It distinguishes this qualified automotive-grade variant from commercial versions like SBR02U100T3G, which lack AEC-Q101 validation and PPAP support.
Can SBR02U100LPQ-7 replace a 1N5819 in an existing design?
Yes, with caveats: it matches the 1N5819's 1 A surge rating and 0.25 A average current, but offers higher 100 V VRRM (vs. 40 V), lower VF (0.72 V vs. ~0.45 V at low current), and superior thermal rating (+150°C vs. +125°C). Layout must accommodate the smaller DFN1006 footprint and verify solder reflow profile compatibility with NiPdAu terminations.
Does SBR02U100LPQ-7 require a heatsink in typical applications?
No external heatsink is required. With RθJA = 235 °C/W on FR-4 and 250 mA IO, self-heating is ~15°C above ambient at full load. Thermal performance is sufficient for most PCB-mounted applications when using the recommended 0.70 mm × 0.30 mm thermal pad per Diodes' outline drawing. Forced airflow or copper pour is only needed above 200 mA continuous in >85°C ambient.
