Product details
Overview
SBRT15U50SP5-13D 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 SBRT15U50SP5-13D datasheet, SBRT15U50SP5-13D pinout, SBRT15U50SP5-13D application, or SBRT15U50SP5-13D equivalent, key selection criteria include thermal resistance (RθJL = 4°C/W), low-profile 1.1mm height, AEC-Q101 qualification, RoHS/Green compliance, and 290A non-repetitive surge rating.
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 avoids rapid leakage rise above 85°C. Its RθJL of 4°C/W enables direct thermal coupling to PCB copper or heatsinks, supporting high-current operation without external cooling.
The POWERDI®5 package integrates a cathode-terminal thermal path with 0.093g mass and UL 94V-0 molding compound. Electrical behavior is characterized across -65°C to +150°C, with VF drift <10% from 25°C to 125°C at 15A and IR remaining ≤0.5mA even at full-rated 50V reverse bias and 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in rectifier and polarity protection roles |
| IO (AV) | 15 A - Average rectified current at TA = 25°C on FR-4; derates to ~8.5A at 100°C ambient per Figure 4 |
| VF (MAX) | 0.47 V - Measured at IF = 15A, TJ = 125°C; enables >95% efficiency in 5V-output DC-DC stages |
| IR (MAX) | 0.5 mA - At VR = 50V, TJ = 125°C; ensures minimal standby power loss in always-on systems |
| RθJL | 4 °C/W - Junction-to-cathode-lead thermal resistance; allows direct thermal anchoring to large copper pour or heatsink |
| IFSM | 290 A - 8.3ms half-sine surge rating; withstands inrush in 12V/15A SMPS input stages |
| CJ | 440 pF - Measured at VR = 25V, f = 1MHz; low capacitance reduces switching noise in high-frequency converters |

Applications
| AC-DC Adapters & Chargers | DC-DC Converters |
|---|---|
Use Scenario: 12V/15A output stage in compact wall-mounted USB-C PD adapter. IC Role / Device Role / Timing Role: Output rectifier replacing dual-Schottky solution to reduce VF-related losses and thermal stress. Use Value: Cuts conduction loss by 0.3W vs. legacy Schottky, enabling 10W higher output in same 12mm height envelope. | Use Scenario: Secondary-side synchronous rectification in isolated 48V→12V telecom DC-DC module. IC Role / Device Role / Timing Role: Freewheeling diode during low-side FET off-time, clamping inductive kickback. Use Value: Maintains <0.5mA IR at 125°C, preventing thermal runaway in sealed modules with limited airflow. |
| Polarity Protection Circuits | Industrial Power Supplies |
Use Scenario: Reverse-voltage protection at 24V input of programmable logic controller (PLC) I/O module. IC Role / Device Role / Timing Role: Series-connected blocking diode ensuring no backfeed during field-wiring errors. Use Value: Withstands 290A surge from hot-plug events while limiting forward drop to ≤0.44V at full 15A load. | Use Scenario: Input rectification in DIN-rail mounted 24V/10A industrial SMPS with extended temperature range. IC Role / Device Role / Timing Role: Primary AC input bridge leg replacement for improved efficiency and reliability. Use Value: Stable 0.17mA IR at 85°C ensures <10mW standby dissipation, critical for fanless enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U50SP5-13 | Identical electrical specs and package; differs only in tape/reel packaging (13-inch reel, no "D" suffix) | No functional difference; used where tape width or reel diameter compatibility is required | Select -13 for legacy automation feeders calibrated to standard 13″ reels |
| SBRT10U50SP5-13D | 10A IO rating, otherwise identical VRRM, VF, IR, and thermal specs | Lower current handling limits maximum continuous load to 10A; suitable for cost-optimized 5–8A designs | Choose when system peak current stays ≤10A and BOM cost reduction is prioritized |
Compared with SBRT15U50SP5-13D, the -13 variant offers identical performance with standard reel logistics, while the 10A variant trades current capacity for lower unit cost-neither provides higher VF or better IR, making the -13D optimal for full 15A thermal margin and automated placement compatibility.

FAQ
What is the thermal resistance from junction to ambient (RθJA) for SBRT15U50SP5-13D under standard conditions?
The typical RθJA is 101°C/W on FR-4 PCB with 2oz copper and minimum recommended pad layout (per AP02001), and 20°C/W on aluminum substrate with 30mm × 30mm copper pad plus 42mm × 20mm × 12mm heatsink. These values define cooling requirements for sustained 15A operation.
Is SBRT15U50SP5-13D suitable for automotive applications?
Yes-it is AEC-Q101 qualified for high-reliability automotive use, including infotainment power supplies and body control modules. Its stable IR up to 150°C junction temperature and robust surge rating meet under-hood thermal and electrical stress requirements.
How does the POWERDI®5 package improve thermal performance over SO-8 or TO-252?
POWERDI®5 achieves RθJL = 4°C/W via direct cathode-lead thermal anchoring, versus >10°C/W for SO-8. Its low 1.1mm profile and exposed metal pad allow efficient heat transfer to inner-layer copper pours, eliminating need for thermal vias or external heatsinks in many 15A designs.
What is the maximum reverse voltage this diode can block continuously?
The peak repetitive reverse voltage (VRRM) is 50V-this is the maximum DC or sinusoidal reverse voltage the device can block continuously without breakdown. It must not be exceeded in circuit design, even transiently, to ensure long-term reliability.
