Product details
Overview
SBR1045SP5-13 from Diodes Incorporated is a 10A Super Barrier Rectifier (SBR®) in PowerDI5 package, rated for 45V peak repetitive reverse voltage, 0.55V max forward voltage at 10A/25°C, and 0.45mA max reverse leakage at 45V/150°C - engineered for high-efficiency freewheeling and bypass roles in solar panel and DC-DC converter power stages.
For engineers reviewing the SBR1045SP5-13 datasheet, SBR1045SP5-13 pinout, SBR1045SP5-13 application, or SBR1045SP5-13 equivalent, key selection criteria include its +200°C maximum junction temperature rating, 3°C/W junction-to-lead thermal resistance, patented low-VF SBR technology, and AEC-Q101 qualification of the automotive-grade variant (SBR1045SP5Q-13).
Technical Context
This Super Barrier Rectifier replaces conventional Schottky diodes in high-current, high-temperature switching applications by combining low forward voltage drop with superior thermal stability and reduced reverse recovery charge. Its structure enables operation up to +200°C junction temperature under DC forward mode conditions.
The device delivers 180A non-repetitive peak surge current capability and exhibits 23ns typical reverse recovery time at IF = 0.5A/IR = 1.0A, supporting high-frequency SMPS designs where conduction loss and thermal management are critical constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage before avalanche; sets upper limit for input/output rail isolation in 12–24V DC-DC and solar string bypass circuits. |
| IO (AV) | 10 A - Continuous average forward current at TA = +25°C with recommended PCB layout; defines usable current capacity in freewheeling paths without forced cooling. |
| VF (MAX) | 0.55 V @ 10A, +25°C - Low conduction loss enables >95% efficiency in 10A-class buck converters and reduces heatsink requirements. |
| IR (MAX) | 0.45 mA @ 45V, +150°C - Ultra-low high-temp leakage preserves system standby power integrity in hot ambient environments like rooftop PV enclosures. |
| RθJL | 3 °C/W - Junction-to-lead thermal resistance confirms direct thermal path to PCB copper; enables reliable 10A operation using only leadframe conduction, no external heatsink. |
| tRR | 23 ns - Fast reverse recovery minimizes switching loss and EMI in >100kHz topologies; avoids shoot-through risk in synchronous rectifier control schemes. |
| PARM | 10,000 W @ 1µs - Avalanche pulse power rating supports robustness against inductive kickback in motor drive and relay driver circuits. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced molded plastic package with exposed leadframe heatsink pad; UL 94V-0 rated, halogen/antimony-free, matte tin annealed terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; electrically connected to heatsink pad on PCB for low-inductance, low-resistance anode routing. |

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-10EWH04-M3 | 45V VRRM, 10A IO, 0.52V VF @ 10A/25°C, but only rated to +175°C TJ max and lacks AEC-Q101 qualification. | Acceptable for commercial SMPS but not suitable for automotive or extended-temperature solar deployments requiring +200°C margin. | Select when cost sensitivity outweighs thermal headroom needs and automotive compliance is unnecessary. |
| ON Semiconductor SBRT10U45 | 45V VRRM, 10A IO, 0.54V VF @ 10A/25°C, TO-277 package (RθJA ≈ 75°C/W), no +200°C rating or AEC-Q101 version. | Higher thermal resistance demands larger PCB copper area; unsuitable for ultra-compact or high-ambient-temperature designs. | Choose only if legacy TO-277 footprint compatibility is mandatory and thermal performance can be compensated externally. |
Compared with VS-10EWH04-M3 and SBRT10U45, the SBR1045SP5-13 offers unique +200°C junction capability and PowerDI5's 3°C/W RθJL - enabling smaller PCB footprints, higher power density, and guaranteed operation in extreme thermal environments where alternatives require derating or additional cooling.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR1045SP5-13 is guaranteed for DC forward operation up to +200°C junction temperature for durations of up to 2 hours, as specified in Note 8 of the datasheet. For indefinite continuous operation, the recommended maximum junction temperature is +150°C under VR ≤ 80% VRRM conditions, with derating applied above that threshold.
Can the PowerDI5 package be hand-soldered using standard reflow profiles?
Yes - the PowerDI5 package is compatible with standard lead-free reflow profiles (J-STD-020 Level 1). Its moisture sensitivity level is rated at MSL1, eliminating bake requirements. The matte tin annealed terminals ensure reliable wetting, and the exposed heatsink pad requires controlled solder paste volume to avoid voiding while maintaining thermal integrity.
How does the SBR1045SP5-13 differ from standard Schottky rectifiers in reverse leakage behavior?
At +150°C and VR = 45V, the SBR1045SP5-13 exhibits only 0.45mA max IR - significantly lower than typical Schottkys (often >5mA at same conditions). This results from its super barrier architecture, which suppresses thermionic emission and enables stable operation in high-temperature solar and industrial environments where leakage-induced power loss is critical.
Is thermal relief required for the heatsink pad during PCB layout?
No - the datasheet explicitly states that the left and right pins must be electrically connected to the heatsink pad on the PCB, forming a unified thermal and electrical node. Standard copper pour connection (no thermal relief) is required to achieve the specified RθJL = 3°C/W and ensure mechanical reliability under thermal cycling.
