Product details
Overview
SBRT15M50AP5-13D from Diodes Incorporated is a 15A, 50V Trench Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring VF = 0.54 V @ 15A/25°C, IR = 0.15 mA @ 50V/25°C, and RθJC = 2 °C/W. It serves as a high-efficiency freewheeling or polarity protection diode in compact AC/DC adapters and DC/DC converters.
For engineers reviewing the SBRT15M50AP5-13D datasheet, SBRT15M50AP5-13D pinout, SBRT15M50AP5-13D application, or SBRT15M50AP5-13D equivalent, key selection criteria include low forward voltage at high current, stable reverse leakage up to +125°C, thermal resistance performance in thin-profile layouts, and RoHS/Green compliance for space-constrained power conversion designs.
Technical Context
This Trench SBR uses patented Super Barrier Rectifier technology to achieve lower forward voltage and superior high-temperature reverse leakage stability versus standard Schottky or fast recovery diodes. Its structure enables VF ≤ 0.54 V at 15A and IR ≤ 0.15 mA at 50V/25°C while maintaining TJ up to +150°C.
The PowerDI5 package delivers RθJC = 2 °C/W and RθJL = 4 °C/W with a 1.1 mm profile, enabling efficient heat transfer to PCB copper pads and suitability for thermally demanding, ultra-thin power supplies where thermal management and board height are critical constraints.

Applications
| AC/DC Adapters & Chargers | DC/DC Converters |
|---|---|
Use Scenario: 12–24 V output stage in 15–30 W USB-C PD wall adapters operating at 200–500 kHz switching frequency. IC Role / Device Role / Timing Role: Output rectifier replacing Schottky diodes to reduce conduction loss and improve light-load efficiency. Use Value: 0.54 V VF lowers output stage loss by ~1.2 W vs. 0.75 V Schottky at 15 A, enabling passive cooling in <20 mm height enclosures. | Use Scenario: Secondary-side synchronous rectifier replacement in isolated 48 V–12 V buck-derived telecom or server POL converters. IC Role / Device Role / Timing Role: Freewheeling diode in active clamp or resonant topologies where low IR prevents cross-conduction during dead time. Use Value: 0.15 mA IR at 25°C and <45 mA at 125°C ensures minimal standby current and stable regulation across temperature. |
| Polarity Protection Circuits | Industrial Power Supplies |
Use Scenario: Reverse-voltage protection at main DC input of programmable logic controllers (PLCs) and sensor nodes powered from 24 V field wiring. IC Role / Device Role / Timing Role: Series-connected input protection diode placed before bulk capacitor and regulator ICs. Use Value: 50 V VRRM and −55 to +150 °C rating ensure robustness against load dump transients and extended outdoor temperature cycling. | Use Scenario: Output rectification in DIN-rail mounted 24 V/15 A industrial SMPS units with forced-air or convection cooling. IC Role / Device Role / Timing Role: High-current output diode handling continuous 15 A load with minimal thermal rise on FR4 PCB. Use Value: RθJC = 2 °C/W and 1.1 mm profile allow full-rated current without heatsink, reducing BOM count and assembly cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15M50AP5-13 | Identical electrical specs and package; differs only in tape/reel size (5000 pcs on 13″ reel vs. 5000 pcs on 13″ reel with different packaging code) | No functional difference; same use cases and layout | Select -13D when traceability or internal logistics require "D"-suffixed part marking per Diodes' packaging convention |
| SBRT15M50AP5-7D | Same die and package; differs in tape/reel quantity (1500 pcs on 7″ reel) and tape width (12 mm) | Suitable for low-volume prototyping or small-batch production where smaller reels reduce inventory holding | Choose -7D for NPI builds or qualification runs requiring shorter tape lengths and faster reel changeovers |
Compared with SBRT15M50AP5-13D, the -13 and -7D variants share identical electrical performance and thermal behavior but differ solely in packaging configuration-making them functionally interchangeable with no design or layout impact.

FAQ
What is the maximum junction temperature and how does it affect reliability?
The SBRT15M50AP5-13D has a rated TJ range of −55 to +150 °C. At 150 °C, its IR increases to 45 mA (vs. 0.15 mA at 25 °C), but remains stable and non-catastrophic. Derating curves show usable current down to ~10 A at 125 °C ambient with proper PCB copper area, ensuring long-term reliability in sealed enclosures.
Is this diode suitable for synchronous rectification replacement?
No - the SBRT15M50AP5-13D is a unidirectional rectifier, not a MOSFET-based synchronous device. It replaces standard Schottky diodes in non-synchronous flyback or forward converters. For synchronous rectification, discrete MOSFETs or dedicated SR controllers (e.g., AP6320x) are required.
How should the PowerDI5 thermal pad be laid out on the PCB?
The exposed cathode pad must be connected to ≥1 in² (645 mm²) of 2 oz copper on the primary side, with ≥4 thermal vias (0.3 mm diameter, filled or capped) to inner ground/power planes. Diodes' recommended pad layout (document DS36758 page 4) specifies 3.054 mm × 5.45 mm stencil aperture for optimal solder fillet and thermal bond.
Does this part meet AEC-Q101 for automotive use?
No - the SBRT15M50AP5-13D is not AEC-Q101 qualified. Diodes offers automotive-grade versions (e.g., SBRT15M50AP5Q) with PPAP documentation, IATF 16949 manufacturing, and extended testing. This part is intended for commercial/industrial applications only.
