Product details
Overview
SBR15U30SP5-13 from Diodes Incorporated is a 15A Super Barrier Rectifier (SBR®) in PowerDI5 package, designed specifically as a bypass diode for photovoltaic modules. It delivers ultra-low forward voltage drop (0.42 V at 15 A, 125°C), supports 30 V peak repetitive reverse voltage, and is rated for +200°C maximum junction temperature to ensure thermal reliability in high-irradiance solar installations.
For engineers reviewing the SBR15U30SP5-13 datasheet, SBR15U30SP5-13 pinout, SBR15U30SP5-13 application, or SBR15U30SP5-13 equivalent, key selection criteria include forward surge capability (280 A, 8.3 ms), high-temperature leakage stability (100 µA at 30 V, 125°C), and PowerDI5 thermal resistance (26 °C/W junction-to-ambient).
Technical Context
This SBR rectifier employs patented Super Barrier technology to achieve lower VF than Schottky diodes while maintaining superior high-temperature leakage performance. Its architecture eliminates minority-carrier storage, enabling fast recovery without softness trade-offs - critical for minimizing power loss in series-string PV bypass configurations.
Rated for continuous operation up to +150°C ambient (with derating), it sustains stable conduction under sustained partial shading conditions. The device's 280 A non-repetitive surge rating handles lightning-induced transients common in rooftop and ground-mount solar arrays without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - blocks full string reverse voltage during shading faults in typical 12–24V PV modules |
| IO | 15 A - supports high-current module strings with minimal conduction loss |
| VF @ 15A, 125°C | 0.42 V - reduces power dissipation to ≤6.3 W per diode under worst-case operating temperature |
| IFSM (8.3 ms) | 280 A - withstands IEC 61000-4-5 level 4 surge events without failure |
| IR @ 30V, 125°C | 100 µA - ensures low leakage-induced hot-spot risk even at elevated cell temperatures |
| RθJA | 26 °C/W - enables compact PCB layout with standard 2 oz copper pad per Diodes' recommended footprint |
| TJ max | +200°C - guarantees long-term reliability under sustained thermal stress in enclosed junction boxes |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry point during forward conduction | Connected to shaded PV substring anode; must be routed with low-inductance trace to minimize voltage overshoot |
| Cathode (K) | Current exit point; electrically tied to exposed thermal pad | Primary thermal path to PCB; requires ≥26 mm² 2 oz copper pour for rated RθJA |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like VF with PN-junction-level high-temperature leakage control - no compromise on efficiency or reliability |
| +200°C maximum junction rating | Validated for 2-hour DC forward mode at 200°C - extends lifetime in sealed, high-ambient enclosures |
| PowerDI5 thermal design | Exposed cathode pad delivers 26 °C/W RθJA with minimum recommended pad layout - simplifies thermal management vs. TO-277 |
| Lead-free & halogen-free | RoHS 3 compliant (2015/863/EU); <900 ppm Br/Cl, <1000 ppm Sb - meets automotive and green energy compliance mandates |
Applications
| Photovoltaic Bypass Protection | High-Temperature Industrial Power Supplies |
|---|---|
Use Scenario: Installed across individual PV substrings in commercial rooftop arrays subject to partial shading and ambient temperatures up to +85°C. IC Role / Device Role / Timing Role: Bypass diode - provides low-loss current shunt path when cells are reverse-biased, preventing hot-spot damage. Use Value: 0.42 V VF at 125°C reduces power loss by >35% versus standard Schottky alternatives, directly improving system yield. | Use Scenario: Used in auxiliary power rails of industrial motor drives housed in non-ventilated cabinets with internal ambient up to +70°C. IC Role / Device Role / Timing Role: Output rectifier - converts transformer secondary AC to regulated DC for gate drivers and sensors. Use Value: 100 µA IR at 125°C prevents excessive standby loss and thermal runaway under sustained high-temperature operation. |
| Energy Storage System (ESS) DC Coupling | Off-Grid Solar Charge Controllers |
Use Scenario: Integrated into bi-directional DC/DC converters coupling lithium-ion battery banks to PV inverters in microgrids. IC Role / Device Role / Timing Role: Reverse-polarity protection diode - blocks regenerative current flow during battery discharge mode. Use Value: 280 A IFSM rating ensures survivability during battery short-circuit events without fuse coordination dependency. | Use Scenario: Mounted on PCBs of PWM-based charge controllers deployed in desert environments with daytime case temperatures exceeding +65°C. IC Role / Device Role / Timing Role: Input rectifier - conditions PV input before MPPT stage under variable irradiance and temperature. Use Value: Stable VF over -65°C to +150°C ambient enables consistent MPPT efficiency across extreme diurnal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency, high-temperature rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15BQ030-M3/45 | 30 V, 15 A Schottky; VF = 0.45 V @ 15 A, 25°C but degrades to 0.55 V @ 125°C; IR = 250 µA @ 125°C | Limited to ≤125°C junction due to thermal runaway risk above that point | Acceptable only where ambient stays below +60°C and surge exposure is low |
| ON Semiconductor MBR1530CT | 30 V, 15 A dual common-cathode Schottky; VF = 0.52 V @ 15 A, 25°C; no 200°C TJ rating; RθJA ≈ 35 °C/W | Requires larger heatsinking; unsuitable for space-constrained PV junction boxes | Only viable if board area allows extra thermal pad and system tolerates higher conduction loss |
Compared with VS-15BQ030-M3/45 and MBR1530CT, SBR15U30SP5-13 uniquely combines 200°C junction rating, 0.42 V VF at 125°C, and 26 °C/W thermal resistance - making it the only qualified option for high-reliability, thermally constrained solar bypass use cases.

FAQ
What is the maximum continuous junction temperature for SBR15U30SP5-13?
The device is selectively rated for +200°C maximum junction temperature under DC forward mode for up to 2 hours, as validated per Note 8 in the datasheet. This rating exceeds standard Schottky limits and enables operation in thermally aggressive enclosures such as sealed PV junction boxes.
Does SBR15U30SP5-13 require a heatsink in typical solar bypass applications?
No external heatsink is required when using Diodes' recommended PowerDI5 pad layout (2 oz copper, minimum area per datasheet Figure). The 26 °C/W RθJA enables direct PCB thermal dissipation sufficient for 15 A continuous conduction at ≤+70°C ambient.
How does SBR15U30SP5-13 compare to standard Schottky diodes in leakage performance?
At 30 V reverse bias and +125°C, SBR15U30SP5-13 exhibits only 100 µA leakage - less than half the 250 µA typical of comparable Schottkys like VS-15BQ030-M3/45. This lower IR significantly reduces hot-spot risk in shaded PV substrings.
Is there an automotive-qualified version of this part?
Yes - the SBR15U30SP5Q is the AEC-Q101 qualified variant, documented in a separate datasheet. It shares identical electrical and thermal specifications but includes additional automotive-grade testing and traceability controls.
