Product details
Overview
SBR15U30SP5Q-13 from Diodes Incorporated is a 15A, 30V Super Barrier Rectifier (SBR®) in PowerDI5 package, engineered for automotive-grade polarity protection and recirculation applications. It delivers ultra-low forward voltage (0.49 V max at 15 A, 25°C), low reverse leakage (0.3 mA max at 30 V, 25°C), and AEC-Q101 qualification - enabling robust operation in engine control units and battery management systems.
For engineers reviewing the SBR15U30SP5Q-13 datasheet, SBR15U30SP5Q-13 pinout, SBR15U30SP5Q-13 application, or SBR15U30SP5Q-13 equivalent, key selection criteria include avalanche energy rating (1074 mJ), thermal resistance (26°C/W on recommended pad), switching speed (66 ns tRR), and IATF 16949 manufacturing compliance.
Technical Context
This SBR diode replaces conventional Schottky rectifiers in high-reliability automotive power rails where thermal runaway risk must be minimized. Its patented super barrier structure enables higher avalanche ruggedness (20,000 W PARM) and lower high-temperature leakage versus standard Schottkys - critical for under-hood environments up to +150°C junction temperature.
The device operates as a single-element unidirectional rectifier with integrated thermal path via bottom-side heatsink pad. Its 400 pF capacitance at 30 V and 66 ns reverse recovery support efficient DC/DC flyback and synchronous rectification topologies without excessive EMI generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating margin in 12 V/24 V automotive systems with load dump transients. |
| IO | 15 A - Average forward current rating at TA = 25°C with 26°C/W thermal pad; supports continuous power delivery in compact PCB layouts. |
| VF (max) | 0.49 V @ 15 A, 25°C - Ultra-low conduction loss reduces power dissipation by >30% vs. standard Schottky alternatives, improving system efficiency and thermal headroom. |
| IR (max) | 0.3 mA @ 30 V, 25°C - Low leakage ensures stable biasing in high-impedance sensing circuits and prevents thermal runaway during elevated ambient conditions. |
| tRR | 66 ns - Fast reverse recovery minimizes switching losses in high-frequency DC/DC converters and reduces EMI in noise-sensitive vehicle networks. |
| EAS | 1074 mJ @ TJ = 25°C - Avalanche energy rating validates ruggedness against inductive kickback in motor drive and solenoid control applications. |
| RθJA | 26°C/W - Junction-to-ambient thermal resistance with 2 oz. copper 16 mm × 16 mm pad; enables reliable 15 A operation without forced air cooling. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced molded plastic package with exposed bottom-side copper pad for direct PCB heatsinking. UL 94V-0 rated, halogen- and antimony-free "Green" compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Forward current entry point | Connected to input power rail (e.g., battery+); requires low-inductance trace routing to minimize voltage overshoot during turn-off. |
| Cathode (Right Pin) | Forward current exit point | Connected to load or ground return; must be routed with adequate copper area to handle 15 A continuous current and support thermal dissipation. |
| Bottom Pad | Thermal & electrical ground plane | Electrically tied to cathode internally; soldered directly to large copper pour for thermal conduction and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR technology | Enables 1074 mJ avalanche energy - 3× higher than comparable Schottky diodes - ensuring survival during inductive fault events in automotive ECUs. |
| Ultra-low VF (0.49 V max) | Reduces conduction loss to ≤1.1 W at 15 A, lowering board temperature rise and eliminating need for additional heatsinks in space-constrained modules. |
| AEC-Q101 qualification | Validated for automotive use including HTOL, temperature cycling, and HTRB testing - required for inclusion in ASIL-B compliant power subsystems. |
| Bottom-side thermal pad | Provides 26°C/W RθJA with standard FR-4 layout - enables 15 A operation at +85°C ambient without derating when using recommended 16 mm × 16 mm copper area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U30SP5-13 | Same die, non-automotive grade; lacks AEC-Q101 qualification and PPAP documentation. | Approved only for industrial/commercial use; not permitted in OEM automotive production. | Select only for cost-sensitive non-automotive prototypes or legacy industrial designs. |
| MBR1530CT | Standard Schottky dual common-cathode; VF = 0.55 V (max), IR = 1.0 mA (max), no avalanche rating. | Higher conduction loss and thermal runaway risk above 100°C; unsuitable for under-hood deployment. | Acceptable only in ambient-controlled cabin electronics where temperature stays below 70°C. |
Compared with SBRT15U30SP5-13 and MBR1530CT, the SBR15U30SP5Q-13 uniquely combines automotive qualification, superior avalanche ruggedness, and lowest VF among 15 A/30 V SBRs - making it the sole choice for safety-critical power rail protection in modern vehicles.

FAQ
What is the maximum junction temperature rating for SBR15U30SP5Q-13?
The device is rated for continuous operation from –55°C to +150°C junction temperature. Its low IR and high EAS allow sustained reliability at the upper limit when mounted on a 2 oz. copper 16 mm × 16 mm pad per Diodes' recommended layout. Derating begins above +125°C ambient per Figure 5 in DS36115 Rev. 6–2.
Is SBR15U30SP5Q-13 pin-compatible with standard PowerDI5 Schottky diodes?
Yes - it uses identical PowerDI5 footprint and pin assignment (anode left, cathode right, bottom pad cathode-connected). However, its internal SBR structure provides higher avalanche energy and lower high-temperature leakage than Schottky equivalents, enabling direct replacement in existing layouts with improved ruggedness.
Does this part require special PCB layout considerations beyond standard PowerDI5 guidelines?
Yes - the bottom thermal pad must be fully soldered to a minimum 16 mm × 16 mm 2 oz. copper area to achieve the 26°C/W RθJA rating. Vias under the pad (≥6 × 0.3 mm diameter) are recommended to enhance vertical heat transfer. Avoid solder mask over the pad to ensure optimal thermal contact.
How does the SBR15U30SP5Q-13 perform in comparison to traditional silicon PN rectifiers?
It offers significantly lower VF (0.49 V vs. ≥0.9 V), faster tRR (66 ns vs. >1 µs), and zero minority-carrier storage - eliminating reverse recovery spikes. Unlike PN devices, it has no soft recovery tail, reducing EMI in high-frequency switching applications such as automotive DC/DC converters.
