Product details
Overview
SBRT15U50SP5-7 from Diodes Incorporated is a 15A, 50V Trench Super Barrier Rectifier (SBR) in POWERDI®5 package, featuring ultra-low 0.47V max forward voltage at 15A/125°C and only 0.5mA max reverse leakage at 50V/125°C. It serves as a high-efficiency rectifier, freewheeling diode, or polarity protection device in compact AC-DC adapters and DC-DC converters.
For engineers reviewing the SBRT15U50SP5-7 datasheet, SBRT15U50SP5-7 pinout, SBRT15U50SP5-7 application, or SBRT15U50SP5-7 equivalent, key selection criteria include thermal resistance (RθJL = 4°C/W), low-profile 1.1mm height, AEC-Q101 qualification, RoHS/Green compliance, and junction-to-ambient performance under FR-4 vs. aluminum substrate layouts.
Technical Context
This TrenchSBR uses proprietary trench-based super barrier technology to achieve lower VF than Schottky diodes while maintaining superior high-temperature IR stability-unlike conventional Schottkys, it sustains <0.5mA leakage at 50V and +125°C. Its 4°C/W junction-to-lead thermal resistance enables high-current operation with minimal temperature rise when soldered to copper pads or heatsinks.
The POWERDI®5 package integrates a thermally optimized leadframe with molded green compound (UL 94V-0), supporting 290A non-repetitive surge current and rated for -65°C to +150°C operation. Electrical behavior is characterized across temperature using short-pulse testing to eliminate self-heating artifacts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe DC/AC peak voltage handling in rectifier or polarity protection roles. |
| IO (AV) | 15 A - Average rectified output current at TA = +25°C; usable up to 12A at +100°C per derating curve. |
| VF (MAX) | 0.47 V @ 15A, +125°C - Ultra-low forward drop minimizes conduction loss in high-efficiency power stages. |
| IR (MAX) | 0.5 mA @ 50V, +125°C - Exceptional high-temp leakage control enables stable operation in hot environments without thermal runaway. |
| RθJL | 4 °C/W - Low junction-to-lead thermal resistance allows direct heat transfer to PCB copper or external heatsink via cathode terminal. |
| CJ | 440 pF @ 25V - Junction capacitance impacts switching noise and EMI in high-frequency DC-DC topologies. |
| IFSM | 290 A @ 8.3ms - Surge rating supports inrush current handling during power-up in adapter and converter inputs. |
Pinout & Package
Packaged in POWERDI®5: compact 6.5mm × 3.97mm surface-mount outline with 1.1mm profile, thermally enhanced leadframe, and green molding compound (UL 94V-0). Cathode and anode terminals are exposed on bottom for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input current entry point | Connected to input rail (e.g., transformer secondary or switch-node); must handle full 15A continuous current and 290A surge. |
| Cathode (Pin 2) | Output current exit / thermal path | Primary output terminal and main thermal conduction path to PCB copper or heatsink; low RθJL = 4°C/W relies on this connection. |
| Exposed Pad (Bottom) | Thermal & electrical cathode extension | Integral part of cathode; requires solder mask-defined thermal pad (per AP02001) for optimal heat dissipation and mechanical reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Super Barrier structure | Enables 0.47V VF at 15A/125°C - reduces conduction loss by ~15–20% vs. comparable Schottky diodes in same package. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - suitable for under-hood and infotainment power supplies. |
| POWERDI®5 thermal design | 4°C/W RθJL enables >12W power dissipation with <50°C rise on 30mm×30mm 2oz Cu pad + heatsink - eliminates need for larger packages. |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); meets EU RoHS 2 and JEDEC MSL Level 1 - supports eco-design and global compliance. |
Applications
| AC-DC Adapters & Chargers | DC-DC Converters |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 12–24W wall adapters for laptops and industrial equipment. IC Role / Device Role / Timing Role: High-efficiency output rectifier replacing standard Schottky diodes to improve efficiency by ≥1.5% at full load. Use Value: Lower VF reduces conduction loss; stable IR prevents thermal drift in enclosed, unventilated enclosures. | Use Scenario: Output rectification in isolated flyback or forward converters operating at 100–500kHz. IC Role / Device Role / Timing Role: Freewheeling diode in secondary-side synchronous rectifier circuits or standalone output stage. Use Value: 440pF junction capacitance limits switching node ringing; 290A IFSM withstands transient overloads during startup. |
| Polarity Protection Circuits | Industrial Power Supplies |
Use Scenario: Reverse-voltage protection at input of 12V/24V industrial controllers and IoT gateways. IC Role / Device Role / Timing Role: Series-connected protection diode placed before main regulator or microcontroller power rail. Use Value: 0.47V drop minimizes voltage headroom loss; 50V VRRM covers wide input range including 24V nominal with surges. | Use Scenario: Primary-side clamp or snubber diode in 100–500W telecom and server PSUs. IC Role / Device Role / Timing Role: Clamp diode absorbing leakage inductance energy during MOSFET turn-off. Use Value: 290A surge rating handles repetitive clamping events; low RθJL prevents localized overheating during burst-mode operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U50SP5-13 | Same die and package; differs only in tape-and-reel quantity (5,000 vs. 1,500 units) and reel size (13″ vs. 7″). | No functional difference; selected for volume production vs. prototyping or low-volume builds. | Choose -13 for high-volume manufacturing; -7 for evaluation, small-batch builds, or inventory flexibility. |
| SBRT10U50SP5-7 | Same POWERDI®5 package and 50V rating, but rated for 10A average current and lower VF (0.45V max @ 10A/125°C). | Lower current capability limits use to ≤10W adapters or low-power DC-DC outputs. | Select when 10A suffices and board space or cost optimization is prioritized over 15A headroom. |
Compared with SBRT10U50SP5-7, the SBRT15U50SP5-7 delivers 50% higher current capacity with only marginal VF increase, making it optimal for 15–24W systems; versus SBRT15U50SP5-13, it offers identical performance with smaller reel logistics for NPI and pilot runs.

FAQ
What is the maximum junction temperature and how does it affect derating?
The SBRT15U50SP5-7 has an operating junction temperature range of -65°C to +150°C. At +150°C, its average rectified current derates to approximately 8A on FR-4 PCB (RθJA = 101°C/W), but maintains ~12A with aluminum substrate and heatsink (RθJA = 20°C/W). Derating curves in Figure 4 define exact current limits per ambient and layout conditions.
Is SBRT15U50SP5-7 pin-compatible with other POWERDI®5 rectifiers?
Yes - all POWERDI®5 rectifiers share identical mechanical footprint and terminal configuration (anode/cathode pinout and exposed pad). However, electrical characteristics such as VF, IR, and IFSM vary significantly between devices; always verify thermal and electrical compatibility before substitution.
Does this diode require a heatsink in typical 15A operation?
Not necessarily - with proper PCB layout (≥30mm×30mm 2oz Cu pad), the SBRT15U50SP5-7 achieves RθJA ≈ 20°C/W and stays within 125°C junction limit at 15A. On standard FR-4, RθJA = 101°C/W limits continuous current to ~6A without additional cooling; heatsink attachment to the exposed cathode pad is recommended above 10A.
How does the TrenchSBR technology differ from standard Schottky diodes?
TrenchSBR combines trench-gate MOS-like structure with super barrier metallurgy to achieve Schottky-level VF while suppressing thermionic emission leakage. Unlike Schottkys, it exhibits <0.5mA IR at 50V/125°C - enabling stable operation in high-temp environments where conventional Schottkys would suffer thermal runaway.
