Product details
Overview
SBR10A45SP5 from Diodes Incorporated is a 10A Super Barrier Rectifier (SBR®) in PowerDI5 package, rated for 45V peak repetitive reverse voltage and 0.53V max forward voltage at 10A/25°C. It features patented SBR technology, 0.4mA max leakage at 45V, and is designed specifically as a bypass diode for photovoltaic modules operating up to +150°C junction temperature.
For engineers reviewing the SBR10A45SP5 datasheet, SBR10A45SP5 pinout, SBR10A45SP5 application, or SBR10A45SP5 equivalent, key selection criteria include its low VF stability across temperature, 200°C thermal reliability rating, 23ns reverse recovery time, and PowerDI5 thermal performance with dual-side heat sinking capability.
Technical Context
This SBR rectifier uses a proprietary super barrier structure that replaces conventional PN junctions with a metal-semiconductor interface optimized for low conduction loss and minimal switching loss. Its 500pF junction capacitance at 4V and 23ns tRR enable high-frequency operation in DC/DC converters without significant ringing or EMI.
The device supports continuous operation at TJ = +150°C and is guaranteed for 2 hours at +200°C under DC forward mode-enabling robust solar panel bypass functionality where sustained partial shading causes localized hot-spot heating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage before avalanche onset; ensures safe operation in 36V nominal PV string systems with transient margin. |
| IO (AV) | 10 A - Average forward current rating at TA = +25°C with FR-4 PCB; derates to ~6.5A at +85°C ambient per Fig. 6. |
| VF Max | 0.53 V @ 10A, 25°C - Low conduction loss reduces power dissipation by >30% vs. standard Schottky diodes of similar rating. |
| IR Max | 0.4 mA @ 45V, 25°C - Ultra-low leakage preserves panel output under reverse bias during shading events. |
| tRR | 23 ns - Fast recovery minimizes switching loss and enables use in high-frequency (>100kHz) isolated DC/DC topologies. |
| RθJA | 60 °C/W - Measured on polyimide PCB; enables higher power density than standard SO-8 or TO-220 alternatives. |
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 path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Input terminal for forward conduction path | Connected to PV cell string cathode side; requires low-inductance layout to suppress voltage overshoot during fast turn-off. |
| Cathode (Right Pin) | Output terminal for forward conduction path | Connected to common bus; dual-pin configuration allows parallel routing to reduce trace resistance and improve thermal spreading. |
| Heat Sink (Bottom Side) | Thermal interface surface | Must be soldered to large copper pour or thermal pad; provides primary thermal path to PCB, not optional. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Enables 0.53V VF at 10A while maintaining <0.4mA IR - superior trade-off vs. Schottky or fast recovery diodes. |
| +200°C Junction Rating (DC Mode) | Guaranteed for 2 hours - ensures survivability during prolonged hot-spot conditions in unventilated solar arrays. |
| PowerDI5 Dual-Side Thermal Path | 60°C/W RθJA on polyimide PCB - delivers 2× thermal performance vs. SO-8 packages at same footprint. |
| Lead-Free & Halogen-Free | RoHS 3 compliant, <900ppm Br/Cl, <1000ppm Sb - meets IEC 61215-2 MQT 17.1 environmental stress requirements. |
Applications
| Photovoltaic Bypass Protection | High-Density DC/DC Converters |
|---|---|
|
Use Scenario: Installed across individual PV cell substrings to prevent thermal runaway during partial shading. IC Role / Device Role / Timing Role: Unidirectional current shunt activated only under reverse bias from shaded cells. Use Value: Enables >98% energy retention in partially shaded 72-cell modules by limiting hotspot temperature rise to <150°C. |
Use Scenario: Output rectification in 12V–48V input isolated flyback or forward converters operating at 200–500kHz. IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier replacement with zero gate drive complexity. Use Value: Reduces conduction loss by 0.3W per diode vs. 10A Schottky, improving full-load efficiency by 0.8% at 100W output. |
| AC/DC Adapter Secondary Side | Industrial Power Supply Hold-Up |
|
Use Scenario: Secondary-side rectification in compact 36W–65W universal-input AC/DC adapters with space-constrained layouts. IC Role / Device Role / Timing Role: Low-VF freewheeling path during transformer reset phase. Use Value: Allows 20% smaller heatsink volume vs. DO-214AB packages while maintaining <65°C case temperature at full load. |
Use Scenario: Input hold-up rectifier in 24V industrial PSUs requiring >20ms ride-through during line dropouts. IC Role / Device Role / Timing Role: Low-loss charging path for bulk capacitors during normal operation; blocks reverse current during brownout. Use Value: Minimizes voltage sag during 10ms–100ms interruptions due to 0.46V VF at 10A, extending functional uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10BQ040-M3/45 | 40V VRRM, 0.45V VF @ 10A, 1000pF CJ - lower voltage rating and higher capacitance. | Limited to ≤32V PV strings; unsuitable for 45V-rated inverters or 48V DC/DC inputs. | Select only when system VRRM margin permits 5V reduction and EMI filtering can accommodate higher CJ. |
| ON Semiconductor SBRT10U45 | 45V VRRM, 0.55V VF @ 10A, 0.5mA IR @ 45V - higher VF and leakage than SBR10A45SP5. | Acceptable for non-critical adapter use but degrades PV bypass efficiency by ~1.2% under partial shading. | Prefer only if supply chain constraints preclude Diodes' SBR series; verify thermal derating at TJ = +150°C. |
Compared with VS-10BQ040-M3/45 and SBRT10U45, the SBR10A45SP5 delivers the lowest VF/IR trade-off at 45V, validated 200°C thermal endurance, and PowerDI5-specific thermal design support - making it the optimal choice for solar bypass and high-efficiency DC/DC rectification where thermal headroom and leakage sensitivity are critical.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR10A45SP5 is rated for continuous operation at TJ = –65°C to +150°C. It is guaranteed for 2 hours at +200°C under DC forward mode (Note 7), but sustained operation above +150°C requires derating per Fig. 5 and validation of PCB thermal design.
Is the PowerDI5 package compatible with standard reflow profiles?
Yes - the PowerDI5 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260°C. Its moisture sensitivity level is MSL 1, eliminating bake requirements prior to assembly.
How does the SBR10A45SP5 compare to standard Schottky diodes in solar bypass use?
Unlike standard Schottky diodes, the SBR10A45SP5 maintains <0.4mA IR at 45V and +125°C (vs. >5mA for typical Schottkys), preventing excessive self-heating during shading. Its 200°C thermal rating also exceeds Schottky limits, enabling reliable long-term field operation.
Does this part support automotive qualification?
The SBR10A45SP5Q variant is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. The standard SBR10A45SP5 is not automotive-qualified but shares identical die and PowerDI5 construction - suitable for industrial and commercial applications only.
