Product details
Overview
SBRT10U50SP5-13 from Diodes Incorporated is a 10A, 50V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, featuring ultra-low 0.45V max forward voltage at 10A/25°C and only 0.3mA max reverse leakage at 50V/125°C. It serves as a high-efficiency freewheeling or polarity protection diode in compact AC/DC adapters and DC/DC converters.
For engineers reviewing the SBRT10U50SP5-13 datasheet, SBRT10U50SP5-13 pinout, SBRT10U50SP5-13 application, or SBRT10U50SP5-13 equivalent, key selection criteria include thermal resistance (RθJC = 2°C/W), low-profile 1.1mm height, AEC-Q101 qualification, RoHS/Green compliance, and junction-to-lead thermal path optimization for PCB-level heat dissipation.
Technical Context
This SBR uses trench-based super barrier technology to achieve lower VF than Schottky diodes while maintaining superior high-temperature IR stability-critical for automotive and industrial power supplies where ambient temperatures exceed 85°C. Its RθJC of 2°C/W and RθJL of 4°C/W enable direct thermal coupling to copper pads or heatsinks via cathode terminal.
The device operates across –55°C to +150°C with IFSM = 320A (8.3ms), supporting robust surge handling in switching power stages. Junction capacitance is not specified in datasheet; reverse recovery behavior is inherently soft due to minority-carrier-free SBR structure, eliminating reverse recovery charge (Qrr ≈ 0).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24–48V DC/DC and adapter secondary-side rectification. |
| IO(AV) | 10 A - Continuous average forward current at TA = 25°C on FR4 with 1-inch² copper pad; derates to ~6.5A at 100°C ambient per Figure 5. |
| VF(MAX) | 0.45 V @ 10A, 25°C - Enables <4.5W conduction loss per diode in 10A output rails, reducing thermal load vs. standard Schottkys. |
| IR(MAX) | 0.3 mA @ 50V, 125°C - Stable leakage ensures minimal standby power loss in high-temp environments like enclosed chargers or under-hood modules. |
| RθJC | 2 °C/W - Low junction-to-case thermal resistance allows efficient heat transfer from die to PCB copper or external heatsink via cathode tab. |
| IFSM | 320 A @ 8.3ms - Withstands high-current transients during startup or fault conditions without degradation in SMPS primary/secondary paths. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive-grade reliability, including temperature cycling, HTRB, and ESD. |
Pinout & Package
Packaged in the thermally enhanced POWERDI®5 surface-mount package (1.1mm profile, 4.0mm × 6.5mm footprint), with exposed cathode thermal pad on bottom side and two gull-wing leads (anode and cathode) on left/right edges. Pins must be electrically connected to PCB copper for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Input terminal for forward conduction; connects to switching node or input rail in buck/flyback secondary or polarity protection circuits. |
| Right Pin | Cathode | Output/return terminal; also serves as primary thermal path-must be soldered to ≥1-inch² copper pour for rated current handling. |
| Bottom Thermal Pad | Cathode Extension | Integral part of cathode; provides low-resistance thermal interface to PCB; requires full-solder coverage for RθJC = 2°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.45V max @ 10A/25°C reduces conduction loss by >30% vs. comparable 10A Schottkys, directly improving efficiency in 10W+ adapters. |
| High-temp IR stability | 0.3mA max @ 50V/125°C prevents thermal runaway in sealed enclosures or high-ambient industrial DC/DC converters. |
| Thermally optimized package | RθJC = 2°C/W and RθJL = 4°C/W enable >70% of heat to exit through cathode lead and pad-critical for thin-profile designs. |
| AEC-Q101 qualified | Validated for automotive under-hood and infotainment power rails requiring extended temperature operation and long-term reliability. |
| Green, RoHS-compliant | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); meets EU Directive 2011/65/EU and J-STD-020 moisture level 1. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U50SP5-13 | Original part: 50V/10A, POWERDI5, RθJC = 2°C/W, AEC-Q101 qualified | N/A | Select for automotive-qualified, thermally constrained 10W+ adapters and DC/DC converters. |
| SBRT10U50SP5-7 | Same die, identical electrical specs, but packaged in 3,000-piece 7-inch tape-and-reel (vs. 5,000 on 13-inch) | Same use cases; differs only in packaging quantity and reel size-no functional impact | Choose -7 variant when smaller reel logistics or lower MOQ align with production planning. |
Compared with SBRT10U50SP5-7, the -13 offers higher volume per reel (5K vs. 3K), reducing changeover frequency in high-throughput SMT lines; both share identical thermal, electrical, and qualification profiles-making them functionally interchangeable where reel size permits.

FAQ
What is the maximum junction temperature and how is it related to ambient operation?
The SBRT10U50SP5-13 has an operating junction temperature range of –55°C to +150°C. At 10A continuous current, its thermal resistance junction-to-ambient (RθJA) is 18°C/W on FR4 with 1-inch² copper. Using TJ = TA + (P × RθJA), maximum ambient temperature for full 10A operation is ~75°C-derating required above that per Figure 5.
Is the POWERDI®5 package lead-free and RoHS compliant?
Yes. The SBRT10U50SP5-13 features a lead-free finish and complies with EU Directive 2011/65/EU (RoHS 2). It is also halogen- and antimony-free ("Green"), containing <900ppm bromine/chlorine and <1000ppm antimony compounds, verified per Diodes Incorporated's material declarations.
Does this SBR have a specified reverse recovery time (trr) or Qrr?
No. As a majority-carrier Trench Super Barrier Rectifier, the SBRT10U50SP5-13 exhibits no reverse recovery charge (Qrr ≈ 0) or measurable trr. Its reverse characteristics are governed solely by junction capacitance and leakage-confirmed by absence of Qrr specification and soft reverse IV curves in Figures 3–4 of DS36318.
Can SBRT10U50SP5-13 replace a standard Schottky diode in existing designs?
Yes-with verification of layout compatibility. Its POWERDI®5 footprint matches common 5-pin SO-style packages, and its 0.45V VF at 10A is lower than most 10A Schottkys (typically 0.55–0.75V). However, confirm cathode thermal pad soldering and ensure no mechanical interference with the 1.1mm profile, especially in stacked PCB assemblies.
