Product details
Overview
SBR05U40CSP-7 from Diodes Incorporated is a 40 V, 0.5 A super barrier rectifier (SBR) in a chip-scale package (X2-WLB1006-2), optimized for low forward voltage (0.46 V @ 500 mA), low reverse leakage (75 µA @ 40 V), and ultra-thin 0.3 mm profile-designed for blocking, boost, and reverse polarity protection in space-constrained portable power rails.
For engineers reviewing the SBR05U40CSP-7 datasheet, SBR05U40CSP-7 pinout, SBR05U40CSP-7 application, or SBR05U40CSP-7 equivalent, key selection criteria include thermal resistance (130 °C/W), junction capacitance (34 pF @ 4 V), and high-temperature reverse leakage stability up to +150 °C ambient.
Technical Context
The SBR05U40CSP-7 employs a proprietary super barrier structure that replaces conventional PN junctions with low-barrier metal-semiconductor interfaces, enabling lower VF than Schottky diodes while maintaining higher VRRM and lower IR than standard silicon rectifiers. Its X2-WLB1006-2 package uses wafer-level ball grid array (WLB) construction with two solderable terminals and 0.578 mm pitch.
It operates across –55 °C to +150 °C, with derated current above +75 °C ambient per Figure 4, and exhibits stable capacitance (34 pF typ. @ 4 V) and minimal VF drift over temperature-0.40 V @ 500 mA and +125 °C-supporting reliable performance in thermally aggressive DC/DC converter outputs and battery protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 5–12 V input rail clamping and reverse-battery protection. |
| IO | 500 mA - Average rectified output current at +25 °C; defines continuous conduction capability in low-power boost converters. |
| VF max | 0.46 V @ 500 mA - Peak forward voltage drop; directly determines conduction loss (≤230 mW) and efficiency in 3.3 V/5 V power paths. |
| IR max | 75 µA @ 40 V - Max reverse leakage at rated VRRM; critical for low-quiescent-current battery backup and always-on circuits. |
| RθJA | 130 °C/W - Junction-to-ambient thermal resistance on FR-4 with 2 oz copper; enables self-heating ≤65 °C rise at full IO, supporting compact layout. |
| Cj | 34 pF @ 4 V - Junction capacitance at 1 MHz; minimizes switching noise and EMI in high-frequency (>1 MHz) DC/DC topologies. |
Pinout & Package
Package: X2-WLB1006-2 - Wafer-level chip-scale package, 1.0 × 0.6 mm footprint, 0.3 mm height, two-terminal anode/cathode configuration with cathode dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to source-side of blocking/boost path; must handle 12 A surge during startup transients. |
| Cathode | Output current exit point | Marked with dot; ties to load or switch node; low-inductance connection essential for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile (0.3 mm) | Reduces board stack height by >30% vs. DFN1006, enabling integration into <1 mm-thick wearables and hearing aids. |
| Low VF (0.36 V typ. @ 100 mA) | Minimizes conduction loss in always-on bias rails, extending battery runtime in IoT sensors and BLE peripherals. |
| Reduced high-temp IR | Leakage remains ≤15 µA @ 10 V and +125 °C, preventing thermal runaway in enclosed automotive cabin modules. |
| Lead-free & Halogen-free | Fully RoHS 2 compliant (<900 ppm Br/Cl, <1000 ppm Sb); meets IPC-J-STD-020 Level 1 moisture sensitivity for reflow compatibility. |
Applications
| USB Power Delivery Input Protection | Wireless Charging Receiver Output |
|---|---|
Use Scenario: Reverse-polarity and overvoltage protection at USB-C PD input stage prior to buck controller. IC Role / Device Role / Timing Role: Reverse protection diode in series with input rail; blocks negative transients and prevents backfeed during adapter hot-swap. Use Value: 0.46 V VF limits input drop to <2% at 500 mA, preserving headroom for 5 V regulation; 75 µA IR avoids loading standby LDOs. | Use Scenario: Output rectification in Qi-compliant 5 W wireless charging receiver ICs. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in secondary-side AC/DC conversion; conducts during positive half-cycle of resonant tank output. Use Value: 34 pF Cj reduces switching node ringing; 130 °C/W RθJA sustains 500 mA output without heatsink in sealed earbud enclosures. |
| BLE Beacon Battery Backup | Industrial Sensor Node Power Path |
Use Scenario: Diode-ORing between primary coin cell and backup supercapacitor in long-life BLE beacons. IC Role / Device Role / Timing Role: Blocking diode isolating backup supply from main battery during normal operation; enables seamless switchover on main battery depletion. Use Value: 4 µA IR typ. @ 10 V minimizes self-discharge of supercap; 0.3 mm height fits under 1.2 mm PCB-mounted coin cell holder. | Use Scenario: Input protection for 24 V industrial sensor nodes powered via PoE or local SMPS. IC Role / Device Role / Timing Role: Boost diode in flyback-derived auxiliary 3.3 V rail; handles 500 mA peak current during transient load steps. Use Value: Stable VF across –40 °C to +85 °C ensures consistent efficiency in factory-floor environments; X2-WLB1006-2 withstands mechanical shock per MIL-STD-202. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SDM05U40CSP | Same X2-WLB1006-2 package, identical VRRM/IO, but VF = 0.48 V max @ 500 mA (vs. 0.46 V); IR = 100 µA max @ 40 V (vs. 75 µA). | Slightly higher conduction loss and leakage; acceptable where 20 mV VF margin and 25 µA IR margin are tolerable. | Prefer SBR05U40CSP-7 when optimizing for lowest possible quiescent loss in battery-critical designs. |
| BAS70-04T | DFN1006 package (1.0 × 0.6 mm), 70 V VRRM, 70 mA IO, VF = 0.85 V @ 10 mA - not a direct rating match; higher VF, lower current, larger RθJA (~200 °C/W). | Only suitable for signal-level or low-current bias applications; cannot replace in 500 mA power paths. | Select only for low-leakage signal clamping; avoid for power rectification due to current and thermal limitations. |
Compared with SDM05U40CSP and BAS70-04T, the SBR05U40CSP-7 delivers the lowest VF and IR within its 40 V/500 mA class in CSP, making it optimal for thermally constrained, high-efficiency portable power rails where leakage and conduction loss directly impact battery life.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR05U40CSP-7 has a specified operating junction temperature range of –55 °C to +150 °C. For continuous DC operation at full 500 mA, thermal design must ensure TJ does not exceed +150 °C-achievable with ≤65 °C ambient rise given its 130 °C/W RθJA on standard FR-4 layout.
Is the X2-WLB1006-2 package compatible with standard reflow profiles?
Yes-the device meets IPC-J-STD-020 Level 1 moisture sensitivity and is qualified for standard lead-free reflow profiles (peak 260 °C). Its tin-plated terminals comply with MIL-STD-202 Method 208, and recommended pad layout is documented in Diodes AP02001.
How does the SBR05U40CSP-7 compare to Schottky diodes in reverse leakage at high temperature?
At +125 °C and 40 V reverse bias, the SBR05U40CSP-7 exhibits ≤15 µA IR-significantly lower than typical Schottky diodes (often >100 µA at same conditions). This reduced leakage improves reliability in thermally demanding applications like enclosed automotive modules.
Can this device be used in place of a standard silicon rectifier in a 40 V flyback snubber circuit?
No-while rated for 40 V VRRM, the SBR05U40CSP-7 is not designed for high-voltage snubbing. Its 12 A IFSM rating supports surge events but lacks the ruggedness and avalanche capability required for snubber clamp duty; use dedicated TVS or high-VRRM fast recovery diodes instead.
