Product details
Overview
SBR1U30CSP-7 from Diodes Incorporated is a 30 V, 1 A super barrier rectifier (SBR) in a chip-scale package (X2-WLB1406-2), delivering VF ≤ 0.48 V at 1 A and IR ≤ 75 µA at 30 V, optimized for low-loss DC/DC conversion and reverse polarity protection in space-constrained portable power rails.
For engineers reviewing the SBR1U30CSP-7 datasheet, SBR1U30CSP-7 pinout, SBR1U30CSP-7 application, or SBR1U30CSP-7 equivalent, key selection criteria include forward voltage at 1 A, high-temperature leakage performance up to +150°C, thermal resistance (RθJA = 140°C/W), and CSP footprint compatibility with ultra-thin mobile PCB layouts.
Technical Context
The SBR1U30CSP-7 uses a proprietary super barrier structure to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature IR stability-VF = 0.41 V at 1 A and +125°C, IR = 15 µA at 30 V and +25°C. Its X2-WLB1406-2 package features solderable pads and a 0.84 mm² board area.
Designed for unidirectional current flow in low-voltage DC paths, it operates across –55°C to +150°C with no derating below +125°C, and supports peak surge currents up to 12 A (8.3 ms half-sine). Junction capacitance is 80 pF at 4 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage without breakdown |
| IO | 1 A - Continuous average forward current under specified thermal conditions |
| VF max | 0.48 V at IF = 1 A - Limits conduction loss to ≤480 mW at full load |
| IR max | 75 µA at VR = 30 V - Ensures minimal standby power loss in battery-critical systems |
| RθJA | 140 °C/W - Requires minimum 2 oz copper pad layout per AP02001 for thermal compliance |
| CJ | 80 pF at VR = 4 V - Affects high-frequency switching noise and EMI in boost converters |
| TJ range | –55°C to +150°C - Enables operation in automotive cabin and industrial edge environments |
Pinout & Package
Package: X2-WLB1406-2 chip-scale package (CSP), 0.84 mm² footprint, 0.30 mm typical height, solderable copper pads, cathode marked by dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to input/source side of DC path; must handle 12 A surge transients |

Key Features
| Feature | Design Value |
|---|---|
| Super barrier architecture | Enables 0.48 V VF at 1 A-15–20% lower than comparable Schottky diodes, reducing heat generation in 3.3 V/5 V rails |
| High-temperature IR stability | IR = 15 µA at 30 V and +25°C; rises only to ~100 µA at +125°C-prevents thermal runaway in sealed enclosures |
| X2-WLB1406-2 CSP | 0.84 mm² area and 0.30 mm profile-enables placement beneath batteries or in <1.0 mm Z-height modules |
| Lead-free & Green compliance | Fully RoHS 2 compliant with <900 ppm Br/Cl and <1000 ppm Sb-meets IPC-1752A Tier 1 reporting requirements |
Applications
| USB Power Delivery Input Protection | Wireless Charging Transmit Stage |
|---|---|
Use Scenario: Reverse-polarity and overvoltage protection at USB-C PD input stage before buck converter. IC Role / Device Role / Timing Role: Blocking diode preventing backfeed into upstream source during fault conditions. Use Value: 0.48 V VF minimizes dropout in 5 V–9 V input range; 75 µA IR preserves battery runtime during sleep mode. | Use Scenario: Boost diode in 15 W Qi transmitter power stage operating at 200–300 kHz switching frequency. IC Role / Device Role / Timing Role: Unidirectional current steering during flyback energy transfer phase. Use Value: 80 pF CJ limits capacitive coupling noise; 140°C/W RθJA allows direct mounting on thermally active coil PCB zones. |
| Wearable Battery Management | Industrial Sensor Node Power Rail |
Use Scenario: Isolation between Li-ion cell and system rail during charging/discharging transitions in hearables. IC Role / Device Role / Timing Role: Reverse protection diode ensuring no current flows from system to battery during deep discharge. Use Value: 0.84 mm² CSP footprint fits within 3.0 × 3.0 mm sensor module; –55°C to +150°C rating supports cold-chain monitoring. | Use Scenario: Output rectification in isolated 3.3 V auxiliary supply derived from 24 V field bus via flyback controller. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement where gate drive complexity is prohibitive. Use Value: 12 A IFSM withstands startup surges; low VF maintains >92% efficiency at 800 mA load across temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SDM1U40CSP | 40 V VRRM, 0.52 V VF at 1 A, 100 µA IR at 40 V | Better reverse margin for 24 V systems; higher VF increases conduction loss in 5 V rails | Choose when VRRM > 30 V required and thermal headroom exists |
| SBRT1A30 | TO-277 package, 30 V, 1 A, 0.49 V VF, 100 µA IR, RθJA = 100°C/W | Larger footprint (3.5 mm²), better thermal dissipation but incompatible with CSP-only layouts | Choose when board space permits and higher ambient temperatures dominate design |
Compared with SDM1U40CSP and SBRT1A30, the SBR1U30CSP-7 uniquely balances ultra-compact size, lowest VF in its class, and tight IR control-making it optimal for thermally dense, battery-sensitive portable designs where every 0.1 mm² and 10 µA matter.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR1U30CSP-7 has a rated operating junction temperature range of –55°C to +150°C. For continuous 1 A DC operation on standard FR-4 with 2 oz copper per AP02001 layout, TJ remains ≤125°C at +85°C ambient-no derating needed below that ambient point.
Is the X2-WLB1406-2 package compatible with standard reflow profiles?
Yes-the device is qualified to J-STD-020 moisture sensitivity level 1 and supports industry-standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C). Pad layout must follow AP02001 to ensure void-free solder joints and mechanical reliability.
How does the SBR1U30CSP-7 compare to conventional Schottky diodes in leakage behavior?
At +125°C and 30 V reverse bias, the SBR1U30CSP-7 exhibits IR ≈ 100 µA-typically 3–5× lower than comparable 30 V Schottky diodes, which often exceed 400 µA under identical conditions, significantly improving thermal stability in sealed enclosures.
Can this device be used in reverse-biased ESD protection roles?
No-it is not characterized or rated for ESD clamping. The SBR1U30CSP-7 is designed strictly for rectification and reverse polarity protection in DC power paths. For ESD protection, Diodes Incorporated recommends dedicated TVS devices such as the D24V0L4P.
