Product details
Overview
SBRT15U100SP5-13D from Diodes Incorporated is a 15A, 100V Trench Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring ultra-low forward voltage (0.7 V max at 15 A, 25°C), <0.20 mA reverse leakage at 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or polarity protection diode in DC/DC converters and motor drive power stages.
For engineers reviewing the SBRT15U100SP5-13D datasheet, SBRT15U100SP5-13D pinout, SBRT15U100SP5-13D application, or SBRT15U100SP5-13D equivalent, key selection criteria include thermal resistance (RθJC = 1°C/W), high-temperature leakage stability (30 µA @ 125°C), compact 1.1 mm profile, and RoHS/Green compliance for space-constrained, thermally demanding designs.
Technical Context
This SBR rectifier employs patented trench-based super barrier architecture to achieve lower VF than Schottky diodes while maintaining superior high-temperature IR stability versus conventional PN junctions. Its low RθJC (1°C/W) enables direct PCB copper pad heatsinking without external sinks in moderate-power applications.
The PowerDI5 package integrates a thermally optimized bottom-side heat sink with dual anode/cathode terminals electrically connected on PCB - enabling high-current conduction with minimal thermal impedance and reduced board area versus TO-220 or DPAK alternatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V DC reverse bias without breakdown in power supply hold-up or flyback clamp circuits |
| IO (avg) | 15 A - supports continuous output current in 48 V industrial SMPS and BLDC motor controllers |
| VF (max) | 0.70 V @ 15 A, 25°C - reduces conduction loss by ~30% vs. standard FRD in 12–48 V systems |
| IR (max) | 30 µA @ 125°C - ensures stable blocking under thermal stress, preventing thermal runaway in sealed enclosures |
| RθJC | 1 °C/W - allows >10 W dissipation with only 10°C junction-to-case rise using minimal copper area |
| Package | PowerDI5 - 3.96 × 6.50 mm footprint, 1.1 mm height, bottom-thermal-pad design for PCB-level thermal management |
| AEC-Q101 | Qualified - validated for automotive under-hood applications including engine control modules and ADAS power supplies |
Pinout & Package
PowerDI5 is a 2-terminal surface-mount package with exposed thermal pad on underside. Left and right terminals are electrically connected to anode and cathode respectively; both must be soldered to matching PCB copper areas for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Terminal | Anode | Main current entry point; requires low-impedance trace routing and thermal pad connection |
| Right Terminal | Cathode | Main current exit point; connects to ground or return path; also tied to thermal pad for heat extraction |
| Bottom Pad | Thermal Sink / Cathode Extension | Electrically connected to cathode; must be soldered to ≥30 mm² copper pour for rated 15 A operation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.56 V typ @ 15 A, 25°C - cuts forward power loss to ≤8.4 W, enabling smaller heatsinks in 50–100 W converters |
| Trench SBR® Technology | Patented structure combining Schottky-like conduction with PN-junction leakage immunity - eliminates trade-off between VF and IR |
| Thermally efficient package | RθJA = 15°C/W (with heatsink) - achieves 125°C junction temp at 10.7 A ambient operation, extending lifetime in hot environments |
| Green & RoHS-compliant | Halogen-free, antimony-free, lead-free finish - meets automotive ELV and IEC 61249-2-21 requirements without process requalification |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U100LTP-13 | Same die, TO-277A package - higher RθJA (25°C/W), no bottom thermal pad | Suitable for lower-power (<8 A) or forced-air-cooled designs where PCB real estate is less constrained | Select when thermal pad assembly is impractical but lead-free TO-277A is preferred over PowerDI5 |
| MBR15100CTG | 15 A dual common-cathode Schottky in TO-220AB - VF ≈ 0.85 V, IR rises to >100 µA @ 125°C | Acceptable for lower-temp environments; lacks AEC-Q101 qualification and Green compliance | Choose only for cost-sensitive, non-automotive applications where leakage stability is secondary |
Compared with SBRT15U100LTP-13 and MBR15100CTG, the SBRT15U100SP5-13D delivers best-in-class thermal performance per unit volume, tighter high-temperature leakage control, and full automotive qualification - making it optimal for space- and reliability-critical 12–48 V power rails.

FAQ
What is the maximum junction temperature and how is it maintained?
The SBRT15U100SP5-13D has a rated operating junction temperature range of –65°C to +150°C. With its RθJC of 1°C/W and recommended 30 mm × 30 mm copper pad, junction temperature stays below 125°C at 15 A ambient operation - verified via thermal imaging and derating curves in Figure 4 of DS36524.
Is this diode suitable for synchronous rectification replacement?
Yes - its 0.7 V VF and fast recovery characteristics enable effective replacement of synchronous MOSFETs in medium-frequency flyback and forward converters where gate drive complexity or cost must be minimized. It does not require control circuitry and maintains efficiency within 2–3% of optimized synchronous designs at 100–300 kHz.
How does the PowerDI5 package compare thermally to DPAK or TO-220?
PowerDI5 offers RθJC = 1°C/W, significantly better than DPAK (≈2.5°C/W) and TO-220AB (≈3.5°C/W). Its bottom thermal pad enables direct PCB copper conduction, eliminating interface resistance from mounting hardware - resulting in up to 40% lower steady-state junction temperature at 15 A versus equivalently rated DPAK rectifiers.
Does the "D" suffix affect electrical performance?
No - the "D" in SBRT15U100SP5-13D indicates 12 mm tape width on 13-inch reel (per Note 5 in DS36524); electrical specs, thermal behavior, and reliability are identical to SBRT15U100SP5-13. Both meet AEC-Q101 and share identical marking, packaging dimensions, and test data.
