Product details
Overview
SBRT15U50SP5 from Diodes Incorporated is a 15A, 50V Trench Super Barrier Rectifier (SBR) in the POWERDI®5 package, featuring ultra-low forward voltage (0.47 V max at 15 A, 25°C), low reverse leakage (0.5 mA max at 50 V, 125°C), and thermal resistance of 4°C/W junction-to-lead - optimized for high-efficiency AC/DC adapters and DC/DC converters.
For engineers reviewing the SBRT15U50SP5 datasheet, SBRT15U50SP5 pinout, SBRT15U50SP5 application, or SBRT15U50SP5 equivalent, this device is selected for high-current, low-VF rectification where thermal management, thin-profile packaging (<1.1 mm height), and stable high-temperature IR performance are critical design requirements.
Technical Context
This TrenchSBR uses advanced trench-based super barrier technology to achieve lower VF than standard Schottky diodes while maintaining superior high-temperature reverse leakage stability - unlike conventional Schottkys, it avoids catastrophic IR rise above 85°C. Its 50 V VRRM rating targets secondary-side rectification in compact offline power supplies.
The POWERDI®5 package integrates a thermally enhanced cathode pad with low RθJL (4°C/W) and supports direct PCB copper heatsinking. Electrical behavior is characterized across -65°C to +150°C, with validated derating curves confirming 15 A average current capability at TJ ≤ 100°C under proper board layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum blocking voltage for secondary-side rectification in ≤12 V output, 10–25 W AC/DC adapters. |
| IO (AV) | 15 A - Sustained average forward current at TA = 25°C with recommended 2 oz. copper pad and heatsink. |
| VF (max) | 0.47 V @ 15 A, 25°C - Reduces conduction loss by ~30% vs. comparable 50 V Schottky, improving efficiency in high-current paths. |
| IR (max) | 0.5 mA @ 50 V, 125°C - Enables reliable operation in thermally constrained environments without thermal runaway risk. |
| RθJL | 4°C/W - Enables efficient heat transfer from junction to cathode pad, supporting >10 W dissipation with minimal ΔT. |
| CJ | 440 pF @ 25 V - Low capacitance minimizes switching noise and EMI in high-frequency DC/DC topologies (e.g., synchronous buck). |
Pinout & Package
Package: POWERDI®5 - surface-mount, thermally enhanced, single-row 2-terminal package with exposed cathode pad (bottom-side heatsink). Dimensions: 4.0 mm × 6.5 mm × 1.1 mm (L × W × H); weight: 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; electrically connected to internal die anode; requires routing to input/high-side node. |
| Right Pin | Cathode | Current exit terminal and thermal interface; must be soldered to large copper area or external heatsink for RθJL = 4°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.47 V max at 15 A, 25°C - directly reduces I²R losses and improves full-load efficiency in 10–25 W adapters. |
| High-temp IR stability | 0.5 mA max at 50 V, 125°C - eliminates need for derating due to leakage-induced thermal instability in enclosed enclosures. |
| Thermally optimized package | RθJL = 4°C/W - enables >10 W continuous power dissipation using only PCB copper, no discrete heatsink required. |
| Low profile | 1.1 mm max height - fits into space-constrained applications such as ultra-thin wall adapters and portable chargers. |
Applications
| AC/DC Adapters & Chargers | DC/DC Converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U50SP5-7 | Same die and specs; differs only in tape-and-reel packaging (1500 pcs/reel vs. 5000 pcs/reel). | No functional difference; used when smaller batch procurement or prototyping volume is required. | Select based on order quantity and assembly line reel compatibility - electrical and thermal performance identical. |
| SBRT10U50SP5 | 10 A IO rating (vs. 15 A); same VF (0.47 V max), VRRM (50 V), and package. | Suitable for ≤10 A output stages; lower cost where full 15 A margin is unnecessary. | Choose when peak load current remains ≤10 A - saves BOM cost without sacrificing VF or thermal performance per amp. |
Compared with SBRT10U50SP5, the SBRT15U50SP5 delivers 50% higher current capacity with identical VF and thermal footprint, making it optimal for future-proofed designs or margin-critical 12–15 A outputs; SBRT15U50SP5-7 offers identical performance in smaller reels for NPI validation.

FAQ
What is the maximum junction temperature for continuous operation?
The SBRT15U50SP5 has an operating junction temperature range of -65°C to +150°C. Continuous operation at 15 A requires thermal design ensuring TJ does not exceed 150°C - typical derating begins at TJ > 100°C per Figure 4, with 15 A supported at TJ ≤ 100°C using recommended PCB layout and heatsinking.
Is the POWERDI®5 package lead-free and RoHS compliant?
Yes. The SBRT15U50SP5 features a lead-free finish and meets EU Directive 2011/65/EU (RoHS 2) requirements. It is also halogen- and antimony-free ("Green" device), with bromine <900 ppm, chlorine <900 ppm (total Br+Cl <1500 ppm), and antimony <1000 ppm.
Can this diode replace a standard Schottky rectifier in existing designs?
Yes - the SBRT15U50SP5 is a direct footprint-compatible replacement for 50 V, 15 A Schottky diodes in POWERDI®5, provided the PCB pad layout follows Diodes' AP02001 guidelines. Its lower VF and superior high-temperature IR stability typically improve efficiency and thermal margin without circuit modification.
What is the surge current rating and test condition?
The non-repetitive peak forward surge current (IFSM) is 290 A, tested under an 8.3 ms single half-sine wave superimposed on rated load. This rating validates robustness against line surges and inrush events in AC/DC front-end and DC/DC input stages.
