Product details
Overview
SBR10U45SP5-13 from Diodes Incorporated is a 10A Super Barrier Rectifier (SBR®) in PowerDI5 package, rated for 45V peak repetitive reverse voltage and ultra-low 0.38V forward voltage at 10A/25°C. It features +200°C maximum junction temperature rating and patented SBR technology optimized for solar panel bypass applications.
For engineers reviewing the SBR10U45SP5-13 datasheet, SBR10U45SP5-13 pinout, SBR10U45SP5-13 application, or SBR10U45SP5-13 equivalent, key selection criteria include thermal reliability at high ambient temperatures, low VF under high DC current, surge robustness (275A IFSM), and RoHS-compliant green packaging with matte tin terminals.
Technical Context
This SBR rectifier employs a proprietary super barrier structure that achieves lower forward voltage than Schottky diodes while maintaining superior high-temperature leakage performance and avalanche ruggedness. Its 275A non-repetitive surge rating supports transient energy absorption in photovoltaic string protection circuits.
The device is thermally characterized for both FR-4 (RθJA = 73°C/W) and polyimide PCBs (RθJA = 31°C/W), with derating curves confirming stable operation up to +150°C ambient when VR ≤ 80% VRRM. Junction temperature is guaranteed to +200°C for short-duration DC forward mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IO | 10 A - Average rectified output current; supports continuous bypass current in 12–24V solar arrays |
| VF @ 10A, 25°C | 0.38 V - Ultra-low forward drop reduces power loss and thermal stress in high-current bypass paths |
| IFSM | 275 A - 8.3ms half-sine surge capability enables reliable handling of lightning-induced transients |
| TJ max | +200°C - Selectively rated junction temperature ensures long-term reliability under sustained high-temperature operation |
| IR @ 45V, 150°C | 75 µA - Low high-temp leakage preserves string efficiency and minimizes hot-spot risk in shaded panels |
| RθJA (FR-4) | 73 °C/W - Thermal resistance baseline for standard PCB layout; requires minimum pad area per datasheet |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U45SP5-13 | Same die, identical electrical specs; differs only in marking code (SBRT vs. SBR) and internal traceability | No functional difference; used interchangeably in same PV bypass designs | Select when legacy BOM references SBRT prefix or distributor inventory favors that variant |
| MBR1045CT | Standard dual Schottky in TO-220AB; VF = 0.55V @ 10A/25°C; RθJA = 40°C/W (with heatsink); no +200°C rating | Requires external heatsink; unsuitable for unventilated PV junction boxes above +70°C ambient | Choose only for cost-sensitive, low-ambient industrial supplies where thermal margin exceeds 40°C |
Compared with SBRT10U45SP5-13, this part offers identical performance but different traceability; versus MBR1045CT, it delivers 31% lower conduction loss and eliminates heatsink dependency-critical for space-constrained, high-reliability solar deployments.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The SBR10U45SP5-13 supports continuous operation up to +150°C ambient when reverse voltage is held at ≤80% of VRRM (≤36V). At full 45V reverse bias, ambient must be limited to +125°C per Figure 7 derating curve. The +200°C junction rating applies only to short-duration DC forward mode testing.
Is this diode suitable for use in automotive applications?
The SBR10U45SP5-13 is not AEC-Q101 qualified. For automotive-grade use, Diodes offers the pin- and package-compatible SBR10U45SP5Q variant, which undergoes full AEC-Q101 stress testing and is documented in a separate automotive datasheet (DS31371Q).
How does the PowerDI5 package improve thermal performance over SMA or SMB packages?
The PowerDI5 exposes the cathode as a large bottom-side thermal pad (18.8mm × 14.4mm recommended), achieving RθJA = 31°C/W on polyimide PCBs-nearly 2× better than SMA packages (~60°C/W). This allows 10A operation without external heatsinks in confined spaces like PV junction boxes.
Can this diode replace a standard Schottky rectifier in an existing design?
Yes-SBR10U45SP5-13 is a direct drop-in replacement for 10A/45V Schottky diodes in PowerDI5 footprint, offering lower VF (0.38V vs. typical 0.55V) and dramatically improved high-temperature leakage (75µA vs. >1mA at 150°C), resulting in measurable efficiency and reliability gains.
