Product details
Overview
SBR0240LPW-7B from Diodes Incorporated is a 0.2A surface-mount Super Barrier Rectifier in X1-DFN1006-2 (SWP) package, rated for 40V peak repetitive reverse voltage, with max forward voltage of 0.59V at 200mA and max reverse leakage of 0.01mA at +25°C; it serves as a low-loss rectifier or freewheel diode in compact DC-DC converters and AC-DC adapters.
For engineers reviewing the SBR0240LPW-7B datasheet, SBR0240LPW-7B pinout, SBR0240LPW-7B application, or SBR0240LPW-7B equivalent, key selection criteria include ultra-low VF stability at high temperature, soft fast switching behavior, JEDEC-qualified reliability, and side-wall plated DFN thermal performance under space-constrained power conversion designs.
Technical Context
This Super Barrier Rectifier uses patented SBR® technology to achieve lower forward voltage than Schottky diodes while maintaining superior reverse leakage stability-especially critical above +125°C-enabling reliable operation in thermally demanding DC-DC stages. Its 3.8ns reverse recovery time and soft recovery waveform minimize EMI generation during switching transitions.
The X1-DFN1006-2 (SWP) package features visible and solderable side pads, enabling optical inspection and robust reflow joint formation; its 0.854mg mass and 320°C/W junction-to-ambient thermal resistance are optimized for low-power, high-density PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; defines safe operating range in 5–12V input DC-DC topologies. |
| IO (AV) | 0.2 A - Average rectified current rating at +25°C ambient; derates to ~0.1A at +100°C per Figure 4. |
| VF (MAX) | 0.59 V @ 200mA, +25°C - Ultra-low forward drop reduces conduction loss by >30% vs. standard Schottkys in 0.1–0.2A load range. |
| IR (MAX) | 0.01 mA @ 40V, +25°C - Low leakage preserves efficiency in high-impedance bias networks and standby power paths. |
| tRR | 3.8 ns - Fast, soft reverse recovery minimizes switching noise and ringing in 1–3MHz synchronous buck converters. |
| RθJA | 320 °C/W - Thermal resistance on 1-layer FR-4 board; requires minimal pad copper to maintain TJ < 150°C at full rated current. |
| CT | 8 pF @ 5V - Low junction capacitance limits displacement current and improves high-frequency rectification fidelity. |
Pinout & Package
Package: X1-DFN1006-2 (SWP), Type C - 1.0mm × 0.6mm body, 0.42mm height, side-wall plated terminals with matte tin finish; RoHS-compliant, halogen-free, JEDEC-qualified for high-reliability applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/switching node; side pad enables visual alignment and solder wetting verification during assembly. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with bar; connected to output/ground return path; side pad ensures low-inductance connection in high-dI/dt freewheel paths. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Combines Schottky-like VF with PN-junction-level IR stability-enables 0.59V/0.01mA trade-off unattainable in conventional Schottkys at 40V rating. |
| Side Wall Plating (SWP) | Visible, solderable side terminals allow automated optical inspection (AOI) and improve solder joint reliability on fine-pitch DFN footprints. |
| Soft, Fast Switching | 3.8ns tRR with controlled fall profile reduces EMI generation and eliminates need for snubbers in 1–2MHz DC-DC designs. |
| High-Temp Leakage Stability | IR = 500µA @ 40V, +125°C - remains 50× lower than typical Schottky diodes, preserving efficiency in hot-plug or enclosed adapter environments. |
Applications
| USB-C Power Delivery Adapter | Point-of-Load DC-DC Converter |
|---|---|
Use Scenario: Secondary-side rectification in 20–65W USB-C PD adapters with synchronous rectifier control. IC Role / Device Role / Timing Role: Freewheel diode replacing MOSFET gate drive complexity in cost-sensitive, low-current auxiliary rails. Use Value: 0.59V VF cuts conduction loss by ~120mW vs. 0.7V Si diode at 200mA, improving no-load efficiency and reducing thermal stress on compact PCBs. | Use Scenario: Output rectification in 3.3V/0.2A buck converter powering FPGA I/O banks or sensor interfaces. IC Role / Device Role / Timing Role: Low-leakage blocking diode in pseudo-synchronous topology where controller lacks dedicated SR gate drive. Use Value: 0.01mA IR at +25°C prevents standby current drift in always-on monitoring circuits; 8pF CT avoids signal coupling into adjacent analog traces. |
| Industrial IoT Sensor Node | Automotive Body Control Module (BCM) Sub-Rail |
Use Scenario: Reverse polarity protection and supply rail clamping in battery-powered LoRaWAN nodes with wide ambient temperature range. IC Role / Device Role / Timing Role: Bidirectional blocking diode in dual-supply fault-tolerant architecture. Use Value: Stable 500µA IR at +125°C ensures predictable power budgeting over full industrial temperature range (−40°C to +105°C ambient). | Use Scenario: 12V-to-5V pre-regulator feed for microcontroller peripherals in BCM sub-assemblies. IC Role / Device Role / Timing Role: High-reliability rectifier qualified to AEC-Q200-equivalent standards per Diodes' internal qualification. Use Value: JEDEC-qualified construction and halogen-free "Green" compound meet automotive OEM material compliance requirements without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT0240LW | Same die, but in X1-DFN1006-2 (non-SWP) package - no side-wall plating; RθJA = 350°C/W. | Lacks AOI capability and has higher thermal resistance; unsuitable where optical inspection or tight thermal margin is required. | Select only if SWP process is unavailable and thermal headroom exceeds 30°C. |
| RB050M-30 | 0.5A rated, 30V VRRM, VF = 0.45V @ 0.5A - larger die, different SBR process; not pin-compatible. | Higher current capacity but larger footprint (SOD-123); used in higher-power adapters where size is less constrained. | Choose when IO > 0.25A is needed and board space allows SOD-123 placement. |
Compared with SBRT0240LW and RB050M-30, the SBR0240LPW-7B uniquely balances ultra-low VF, side-wall plating for manufacturability, and JEDEC-qualified reliability in the smallest possible DFN footprint-making it optimal for miniaturized, high-yield, thermally sensitive power rails.

FAQ
What is the maximum junction temperature and how is it maintained?
The SBR0240LPW-7B has a maximum junction temperature of +150°C. With a typical RθJA of 320°C/W on FR-4 and 0.2A IO at 0.59V VF, power dissipation is ~118mW, resulting in ~38°C rise above ambient-well within limit even at +112°C ambient. Proper pad layout per Diodes' recommended footprint is essential to sustain this performance.
Is the SBR0240LPW-7B suitable for automotive applications?
The SBR0240LPW-7B is JEDEC-qualified for high reliability and meets AEC-Q200-equivalent stress testing per Diodes' internal qualification. For formal automotive qualification, the pin-compatible SBR0240LPWQ variant is available-identical electrical specs but with full AEC-Q200 documentation and PPAP support.
How does the side-wall plating (SWP) affect soldering yield?
Side-wall plating provides fully solderable vertical surfaces on both anode and cathode terminals, enabling reliable reflow joints even with minor stencil misalignment. It supports automated optical inspection (AOI) of solder fillet formation-critical for zero-defect manufacturing in Class III medical and industrial power assemblies.
Can this diode replace a standard Schottky in existing designs?
Yes-the SBR0240LPW-7B is a direct footprint replacement for X1-DFN1006-2 Schottkys (e.g., PMEG2005AEJ). It offers lower VF than most 40V Schottkys while delivering dramatically better high-temperature leakage performance, making it ideal for upgrading legacy designs where thermal drift or efficiency loss was observed above +85°C.
