Product details
Overview
SBR07U20LPS-7 from Diodes Incorporated is a 20 V, 700 mA surface-mount Super Barrier Rectifier (SBR®) with ultra-low forward voltage (0.55 V max at 0.7 A, +25°C), 50 µA max reverse leakage at 20 V, and +150°C junction temperature rating-designed for high-efficiency DC-DC converters and freewheeling paths in compact power supplies.
For engineers reviewing the SBR07U20LPS-7 datasheet, SBR07U20LPS-7 pinout, SBR07U20LPS-7 application, or SBR07U20LPS-7 equivalent, key selection criteria include forward voltage drop at 0.7 A, thermal resistance (224 °C/W), reverse avalanche capability, soft switching behavior, and X2-DFN1006-2 package compatibility with high-density PCB layouts.
Technical Context
This SBR rectifier uses patented Super Barrier technology to achieve lower VF than Schottky diodes while maintaining superior reverse avalanche ruggedness and higher TJ rating than standard Schottkys. It operates reliably up to +150°C and exhibits soft, fast switching with minimal reverse recovery ringing.
Rated for 20 V repetitive reverse voltage and 7 A non-repetitive surge current (8.3 ms half-sine), it supports capacitive-load derating (−20% IO) and meets JEDEC high-reliability standards. Its NiPdAu-plated copper leadframe ensures robust solderability per MIL-STD-202, Method 208.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum blocking voltage before breakdown; defines safe operating range in 3.3 V–12 V output rails. |
| IO (AVG) | 700 mA - Continuous DC forward current; suitable for low-power SMPS outputs and auxiliary bias rails. |
| VF (Max) | 0.55 V @ 0.7 A, +25°C - Ultra-low conduction loss; reduces power dissipation by ~30% vs. comparable 0.8 V Schottkys. |
| IR (Max) | 50 µA @ 20 V, +25°C - Low leakage preserves efficiency in standby and light-load conditions. |
| RθJA | 224 °C/W - Thermal resistance on FR-4 with minimum pad layout; enables operation up to +150°C junction temp with modest airflow. |
| TJ Range | −65°C to +150°C - Extended temperature capability supports automotive under-hood and industrial ambient environments. |
Pinout & Package
Package: X2-DFN1006-2 - 1.0 mm × 0.6 mm, 0.37 mm height, 2-terminal surface-mount plastic package with NiPdAu finish and cathode-marked side (bar).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry | Connected to switch node or inductor output; requires low-inductance routing to minimize switching spikes. |
| Cathode (Pin 2, marked side) | Forward current exit / output rail connection | Directly ties to output capacitor ground reference; critical for minimizing loop inductance in buck freewheeling path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.55 V max at full rated current-reduces conduction loss and thermal stress in space-constrained 1 W–3 W DC-DC stages. |
| Super Barrier Technology (SBR®) | Patented structure delivers Schottky-like VF with improved reverse avalanche energy handling vs. conventional Schottkys. |
| +150°C TJ rating | Enables use in thermally demanding locations (e.g., near power inductors or MOSFETs) without derating. |
| Soft, fast switching | Minimizes EMI generation during turn-off; eliminates need for snubbers in low-noise portable and medical power designs. |
Applications
| Buck Converter Freewheeling Diode | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Used as the low-side freewheeling diode in 3.3 V/5 V synchronous-buck or pseudo-synchronous converter outputs delivering ≤700 mA. IC Role / Device Role: Provides continuous current path during high-side switch off-time; clamps inductor flyback voltage. Use Value: 0.55 V VF minimizes conduction loss and improves light-load efficiency over alternatives; soft switching suppresses EMI in noise-sensitive applications. |
Use Scenario: Placed in series with VIN to protect downstream 3.3 V logic or USB peripherals from accidental negative supply connection. IC Role / Device Role: Unidirectional current gate; blocks reverse current while passing forward current with minimal drop. Use Value: 0.55 V VF ensures <10 mW power loss at 20 mA reverse protection current-critical for battery-powered devices. |
| DC-DC Auxiliary Bias Supply | Low-Power SMPS Output Rectification |
|
Use Scenario: Rectifies isolated 5 V or 12 V auxiliary winding output in flyback or forward converters powering control ICs and gate drivers. IC Role / Device Role: Converts AC winding voltage to regulated DC bias rail; handles intermittent peak loads up to 7 A surge. Use Value: 7 A IFSM rating withstands startup surges; +150°C TJ allows placement near hot components without thermal derating. |
Use Scenario: Final-stage rectifier in compact 1–2 W offline or DC-input SMPS for IoT sensors and wearables. IC Role / Device Role: Delivers clean, low-loss DC output; replaces larger SOD-123 or SMA packages in ultra-thin designs. Use Value: X2-DFN1006-2 footprint saves >60% board area vs. SOD-123; 0.001 g weight supports lightweight portable assemblies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, low-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT07U20LPS-7 | Same die, but with enhanced moisture sensitivity level (MSL 1) and tighter VF binning (0.48 V max @ 0.7 A); identical X2-DFN1006-2 package. | Preferred for high-reliability industrial or automotive-qualified BOMs requiring tighter parametric consistency. | Select when production lot-to-lot VF stability is critical; otherwise, SBR07U20LPS-7 offers cost-optimized performance. |
| APL3002TSG-7 | 0.6 V VF max @ 0.7 A, 100 µA IR max @ 20 V, same 20 V VRRM and X2-DFN1006-2 package; no SBR® patent or avalanche rating specified. | Acceptable where soft switching and avalanche ruggedness are not required; lower cost but higher conduction loss. | Choose only if design tolerates +9% conduction loss and does not require guaranteed avalanche survivability. |
Compared with SBRT07U20LPS-7, the SBR07U20LPS-7 trades tighter VF control for broader MSL compliance; versus APL3002TSG-7, it delivers verified avalanche robustness and 10% lower typical VF-making it preferable for thermally constrained or reliability-critical freewheeling roles.

FAQ
What is the maximum junction temperature and how does it affect layout?
The SBR07U20LPS-7 supports a maximum junction temperature of +150°C. This allows placement near heat-generating components like power inductors or MOSFETs without mandatory thermal vias-provided the PCB uses the recommended minimum pad layout (0.70 mm × 0.40 mm anode/cathode pads) and maintains ≥0.2 mm clearance to adjacent copper.
Is this device qualified for automotive applications?
The SBR07U20LPS-7 is not AEC-Q200 qualified. For automotive use, Diodes recommends the Q-suffix variant SBRT07U20LPSQ-7, which is manufactured in IATF 16949-certified facilities and supports PPAP documentation. The base part meets JEDEC high-reliability standards but lacks automotive-specific qualification testing.
How does its soft switching behavior reduce EMI?
Unlike abrupt-recovery diodes, the SBR07U20LPS-7 exhibits gradual reverse recovery with minimal stored charge-resulting in dV/dt-controlled turn-off and suppressed high-frequency ringing. This eliminates the need for RC snubbers in ≤1 MHz buck converters, reducing BOM count and board area in EMI-sensitive medical or audio power supplies.
Can it replace a standard Schottky diode in existing designs?
Yes-the SBR07U20LPS-7 is a direct footprint replacement for X2-DFN1006-2 Schottkys (e.g., APD1002TSG-7). It provides lower VF and superior avalanche capability, but requires verification of reverse voltage margin since its 20 V VRRM matches common 3.3 V/5 V rail designs-not higher-voltage applications.
