Product details
Overview
SBRT15U100SP5 from Diodes Incorporated is a 15A, 100V Trench Super Barrier Rectifier (SBR®) in PowerDI5 package, featuring ultra-low forward voltage (0.7 V max @ 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 control circuits.
For engineers reviewing the SBRT15U100SP5 datasheet, SBRT15U100SP5 pinout, SBRT15U100SP5 application, or SBRT15U100SP5 equivalent, key selection criteria include forward voltage at 12–15 A, high-temperature leakage stability up to +150°C, thermal resistance (RθJC = 1°C/W), AEC-Q101 compliance, and PowerDI5 footprint compatibility with thin-profile PCBs.
Technical Context
This SBR rectifier uses patented trench-based super barrier architecture to achieve lower VF than Schottky diodes while maintaining higher VRRM and superior high-temperature IR stability. Its low RθJC (1°C/W) enables direct heatsink mounting via the exposed bottom thermal pad.
The device operates across –65°C to +150°C, with derated IO down to ~8 A at TC = +125°C (per Figure 4), and exhibits <30 μA IR at VR = 100 V and TJ = +125°C - critical for thermally constrained automotive and industrial power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Blocks up to 100 V DC or peak reverse voltage without breakdown; suitable for 48 V bus and 12 V automotive systems. |
| IO (avg) | 15 A - Continuous average forward current at TA = +25°C with adequate heatsinking; supports high-current DC/DC output stages. |
| VF (max) | 0.70 V @ 15 A, +25°C - Minimizes conduction loss (≤10.5 W dissipation at full load), improving efficiency over standard FRDs. |
| IR (max) | 0.20 mA @ 100 V, +25°C; 30 μA @ 100 V, +125°C - Enables stable operation in high-temp environments without thermal runaway risk. |
| RθJC | 1°C/W - Junction-to-case thermal resistance allows direct thermal coupling to PCB copper or external heatsink; enables compact thermal design. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors, including HTGB, HTRB, and temperature cycling. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed copper thermal pad on bottom side; 1.1 mm profile; RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Forward current input terminal | Connected to high-side switching node (e.g., MOSFET drain); must be routed with low-inductance trace. |
| Cathode (Right Pin) | Forward current output / reverse blocking terminal | Connects to output rail or ground return; forms low-VF path during freewheeling phase. |
| Thermal Pad (Bottom) | Thermal interface / electrical ground (cathode-connected) | Must be soldered to ≥30 mm² copper pour for optimal RθJA; electrically tied to cathode per internal construction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high current | 0.56 V typ @ 15 A, +25°C - Reduces conduction loss by >30% vs. comparable FRD, directly lowering thermal load in 12–48 V converters. |
| High-temperature IR stability | 30 μA @ 100 V, +125°C - Prevents thermal runaway in under-hood automotive modules where ambient exceeds +85°C. |
| PowerDI5 thermal performance | RθJC = 1°C/W - Enables >10 W continuous dissipation with minimal case temperature rise when mounted on 50×50 mm heatsink. |
| AEC-Q101 qualification | Passed HTGB, HTRB, and TC1000 - Validated for use in engine control units, ADAS power supplies, and body electronics. |
Applications
| Automotive DC/DC Converter | Industrial Motor Drive Freewheeling |
|---|---|
Use Scenario: Step-down converter supplying 5 V/3.3 V from 12 V battery in infotainment head unit. IC Role / Device Role / Timing Role: Output rectifier in synchronous buck topology; conducts during low-side FET off-time. Use Value: 0.56 V VF reduces output stage loss by ~1.2 W vs. FRD alternative, lowering thermal stress on small PCB area. |
Use Scenario: H-bridge driver for 24 V BLDC fan in HVAC system. IC Role / Device Role / Timing Role: Freewheeling diode across motor winding; clamps inductive kickback during PWM turn-off. Use Value: Low IR at +125°C prevents leakage-induced shoot-through risk during sustained high-temp operation. |
| USB-C PD Power Path Protection | Telecom PoE Midspan Rectification |
Use Scenario: Polarity protection and reverse-current blocking in 20 V/5 A USB-C PD port. IC Role / Device Role / Timing Role: Series-blocking diode in hot-swap path; conducts only during correct plug insertion. Use Value: 0.7 V VF limits voltage drop to ≤3.5% at full load, preserving PD negotiation margin and minimizing heat in slim enclosure. |
Use Scenario: 48 V DC input rectification in IEEE 802.3at PoE midspan injector. IC Role / Device Role / Timing Role: Input bridge leg component; handles continuous 15 A input current with low loss. Use Value: RθJC = 1°C/W allows direct thermal coupling to aluminum chassis, eliminating need for discrete heatsink in space-constrained design. |
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-7 | Same die, TO-277A package (no thermal pad); RθJC = 2.5°C/W; VF identical. | Larger footprint; less efficient thermal transfer; unsuitable for ultra-thin or high-power-density layouts. | Select when legacy TO-277A footprint is required and thermal budget allows higher junction rise. |
| MBR15100CT | 15 A dual common-cathode Schottky; VF ≈ 0.82 V @ 15 A; no AEC-Q101; IR rises sharply above +85°C. | Higher conduction loss; not qualified for automotive; limited to commercial-temp industrial use. | Choose only for cost-sensitive non-automotive designs where leakage and qualification are not critical. |
Compared with SBRT15U100LTP-7 and MBR15100CT, the SBRT15U100SP5 uniquely combines AEC-Q101 qualification, PowerDI5's 1°C/W RθJC, and sub-0.7 V VF at 15 A - making it the only option for thermally aggressive, safety-compliant automotive power conversion.

FAQ
What is the maximum continuous forward current rating for SBRT15U100SP5 at +125°C case temperature?
Per Figure 4 in DS36524 Rev. 9-2, the DC forward current derating curve shows IO ≈ 8 A at TC = +125°C. This reflects thermal limitation due to RθJC = 1°C/W and power dissipation constraints-not an electrical limit-and assumes proper heatsinking to maintain TC ≤ +125°C.
Is the thermal pad on the PowerDI5 package electrically isolated or connected to a terminal?
The exposed bottom thermal pad is internally connected to the cathode terminal. The datasheet's mechanical drawing and "Terminal Connections" note confirm left pin = anode, right pin = cathode, and bottom pad = cathode. PCB layout must tie this pad to the cathode net-no isolation required or recommended.
How does SBRT15U100SP5 compare to standard Schottky rectifiers in reverse leakage at elevated temperature?
At VR = 100 V and TJ = +125°C, SBRT15U100SP5 exhibits ≤30 μA IR, whereas typical 15 A Schottkys exceed 500 μA under same conditions. This 15× lower leakage suppresses thermal runaway risk in high-ambient applications like under-hood automotive modules.
Can SBRT15U100SP5 be used in a synchronous rectifier configuration?
No - SBRT15U100SP5 is a unidirectional, passive rectifier with fixed anode/cathode polarity and no gate control. It cannot replace a MOSFET in synchronous rectification. It functions only as a freewheeling or output rectifier in non-synchronous topologies such as standard buck or flyback converters.
