Product details
Overview
SBR10A45SP5Q-13 from Diodes Incorporated is a 10A, 45V Super Barrier Rectifier (SBR®) in PowerDI5 package, optimized for solar bypass diode applications with 0.53V max forward voltage at 10A, 0.4mA max reverse leakage at 45V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SBR10A45SP5Q-13 datasheet, SBR10A45SP5Q-13 pinout, SBR10A45SP5Q-13 application, or SBR10A45SP5Q-13 equivalent, key selection criteria include its 200°C maximum junction temperature rating, low thermal resistance (60°C/W on polyimide PCB), and patented SBR technology enabling superior high-temperature stability versus Schottky alternatives.
Technical Context
This SBR rectifier uses a proprietary super barrier structure to achieve lower forward voltage than standard PN junction diodes while maintaining significantly lower reverse leakage than Schottky diodes-especially above 125°C. Its 23ns reverse recovery time supports high-frequency switching in DC/DC converters without excessive switching loss.
The device is rated for 180A non-repetitive surge current and features a thermally enhanced PowerDI5 package with exposed heat sink pad. It operates across –65°C to +150°C ambient, with derated current up to +200°C junction temperature under controlled conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in solar panel string bypass configurations. |
| IO (AV) | 10 A - Average forward rectified current at TA = +25°C; usable up to 8A at +125°C ambient per derating curve. |
| VF Max | 0.53 V @ 10A, +25°C - Low conduction loss enables >98% efficiency in high-current solar bypass paths. |
| IR Max | 0.4 mA @ 45V, +25°C - Ultra-low leakage preserves string voltage integrity under partial shading. |
| tRR | 23 ns - Fast recovery minimizes switching losses in high-frequency DC/DC topologies. |
| RθJA | 60 °C/W - Measured on polyimide PCB; enables compact thermal design in space-constrained automotive modules. |
| TJ Max | +200°C - Selectively rated junction temperature ensures long-term reliability in hot under-hood environments. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed copper heat sink pad on bottom side. Pins left and right must be electrically connected on PCB for optimal thermal and current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Forward current input terminal | Connected to solar panel negative string side; designed for high-current solder joint reliability. |
| Cathode (Right Pin) | Forward current output terminal | Connected to system ground or common return; carries full 10A load current with minimal IR drop. |
| Heat Sink Pad (Bottom) | Thermal and electrical ground path | Must be soldered to large copper pour for thermal dissipation; electrically tied to cathode internally. |
Key Features

Applications
| Solar Panel Bypass Protection | Automotive DC/DC Converter Output Stage |
|---|---|
Use Scenario: Installed across individual PV cell substrings to prevent hot-spot damage during partial shading or module mismatch. IC Role / Device Role / Timing Role: Unidirectional current shunt that conducts only when reverse-biased string voltage exceeds forward drop.

Use Scenario: Used as secondary-side rectifier in 12V–48V automotive buck converters powering ADAS sensors or infotainment systems. IC Role / Device Role / Timing Role: High-efficiency synchronous rectification replacement with no gate drive complexity. Use Value: Reduces conduction loss by 35% vs. standard FRD, lowering thermal load in sealed ECU enclosures. |
| Industrial AC/DC Adapter Secondary Side | Energy Storage System (ESS) Module Balancing |
Use Scenario: Rectifies transformer secondary output in universal-input 100–240VAC adapters delivering 5–24V at ≥10A. IC Role / Device Role / Timing Role: Main output rectifier handling continuous average current with minimal voltage sag. Use Value: Enables compact adapter designs via 0.53V VF and 60°C/W RθJA, reducing heatsink volume by 40%. |
Use Scenario: Provides cell-level bypass in lithium-ion battery packs during charging to equalize state-of-charge across series cells. IC Role / Device Role / Timing Role: Precision-balancing diode activated only during overvoltage conditions on individual cells. Use Value: Prevents cell degradation with 0.4mA IR at 45V, ensuring <0.1% self-discharge contribution per bypass path. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U45SP5Q-13 | 0.42V VF max @ 10A, +25°C; same 45V VRRM and PowerDI5 package | Better conduction efficiency but higher IR (0.8mA) limits use in ultra-low-leakage solar bypass | Select when thermal budget dominates leakage concerns-e.g., forced-air-cooled industrial PSUs |
| MBR1045CT | Standard Schottky; 0.75V VF max @ 10A, +25°C; TO-220AB package; no AEC-Q101 | Larger footprint, higher conduction loss, and unqualified for automotive use | Acceptable only for cost-sensitive, non-automotive, non-solar applications with ample thermal margin |
Compared with SBRT10U45SP5Q-13, SBR10A45SP5Q-13 trades 0.11V higher VF for 50% lower leakage-critical for shaded solar strings. Versus MBR1045CT, it delivers 30% lower power loss and qualifies for automotive systems without redesigning mechanical layout.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR10A45SP5Q-13 is selectively rated for +200°C maximum junction temperature, verified under DC forward mode for up to two hours. For indefinite operation, the datasheet specifies TJ ≤ +150°C under normal conditions, with derating applied above +125°C ambient per Figure 6.
Is the PowerDI5 package lead-free and RoHS compliant?
Yes-the SBR10A45SP5Q-13 uses matte tin annealed over copper leadframe and green molding compound, meeting EU RoHS 3 (2015/863/EU), halogen-free (<900ppm Br/Cl, <1000ppm Sb), and IATF 16949 manufacturing standards.
How does the SBR technology differ from standard Schottky rectifiers?
SBR uses a modified metal-semiconductor junction with integrated barrier enhancement, achieving VF comparable to Schottky diodes but with IR values closer to PN rectifiers-especially above 125°C, where conventional Schottkys suffer exponential leakage rise.
Can this diode be used in parallel configurations?
Parallel operation is not recommended without external balancing-its positive temperature coefficient of VF provides limited inherent current sharing. For >10A requirements, use a single higher-rated SBR (e.g., SBR20A45SP5Q) rather than paralleling units.
