Product details
Overview
SBR10100CTB from Diodes Incorporated is a 10A dual common-cathode Super Barrier Rectifier in TO263AB package, rated for 100V peak reverse voltage, 0.84V max forward voltage at 5A per leg and 0.2mA max reverse leakage at 100V/25°C. It serves as a high-efficiency output rectifier or freewheel diode in DC-DC converters and AC-DC adapters operating under high-temperature conditions.
For engineers reviewing the SBR10100CTB datasheet, SBR10100CTB pinout, SBR10100CTB application, or SBR10100CTB equivalent, key selection criteria include its ultra-low VF stability across temperature, AEC-Q101 qualification, TO263AB thermal performance (RθJC = 6°C/W), and dual-leg current sharing capability in compact surface-mount form.
Technical Context
This device implements patented Trench SBR® technology to achieve superior avalanche ruggedness compared to Schottky diodes while maintaining low forward voltage. Its dual common-cathode configuration supports parallel operation of two 5A legs with shared cathode terminal, enabling balanced current distribution in high-current outputs.
Thermal design is enabled by low junction-to-case resistance (6°C/W) and compatibility with standard 2-inch² aluminum PCB heatsinking. Reverse leakage remains tightly controlled up to +125°C (40μA at 100V), mitigating thermal runaway risk in enclosed power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 12–48V output rectification. |
| IO (per leg) | 5 A - Continuous average forward current rating per anode leg; enables 10A total output with dual-leg layout. |
| VF (max) | 0.84 V @ 5A, 25°C - Low conduction loss improves efficiency >95% in 12V/5A buck converter designs. |
| IR (max) | 0.2 mA @ 100V, 25°C - Minimal leakage preserves standby power budget and prevents thermal instability at elevated ambient temperatures. |
| RθJC | 6 °C/W - Enables direct thermal path to heatsink; supports 10A operation with ≤60°C junction rise above case at 25°C ambient. |
| AEC-Q101 | Qualified - Meets automotive-grade reliability requirements for under-hood DC-DC modules and infotainment power supplies. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, molded plastic case with matte tin–annealed copper leadframe; 1.6g mass; UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input terminal for first rectifier leg | Accepts AC or switched input; electrically isolated from Anode 2; shares cathode with second leg. |
| Cathode (Pin 2) | Common output node for both legs | Single low-inductance return path; connects directly to output capacitor ground plane for reduced EMI. |
| Anode 2 (Pin 3) | Input terminal for second rectifier leg | Enables interleaved or parallel rectification; identical electrical specs to Anode 1; symmetrical layout supports thermal balance. |
Key Features
| Feature | Design Value |
|---|---|
| Trench SBR® technology | Provides 80A non-repetitive surge rating (IFSM) and robust avalanche energy handling-critical for transient-limited industrial SMPS. |
| Ultra-low VF drift with temperature | VF = 0.71V @ 5A/125°C - maintains high efficiency even in thermally constrained enclosures like sealed LED drivers. |
| High-temp IR stability | IR = 40μA @ 100V/125°C - eliminates thermal runaway risk in +85°C ambient telecom power modules. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb); meets EU RoHS 3 and automotive environmental mandates. |
Applications
| DC-DC Converters | AC-DC Adapters |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 12V/10A isolated flyback converters for industrial PLC power supplies. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete Schottkys; reduces component count and PCB footprint.

IC Role / Device Role / Timing Role: Freewheel diode in secondary-side synchronous rectifier stage; handles 10A peak pulse currents during switching transitions. Use Value: 40μA IR at 125°C prevents output voltage droop and thermal runaway during sustained high-load operation. |
| Automotive Infotainment | Telecom Power Modules |
Use Scenario: 5V/6A auxiliary rail generation in head-unit DC-DC converters exposed to under-dash temperatures up to +105°C. IC Role / Device Role / Timing Role: Blocking diode isolating backup battery from main supply; must withstand reverse bias during cold-crank events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U100CT | Same TO263AB package, but uses planar SBR® (not trench); VF = 0.87V @ 5A/25°C; IFSM = 60A. | Lacks AEC-Q101 qualification; lower surge rating limits use in automotive transients. | Select when cost sensitivity outweighs surge margin and automotive compliance. |
| SS10100CT | Standard Schottky; VF = 0.82V @ 5A/25°C but IR = 2.0mA @ 100V/25°C; no avalanche rating. | Unsuitable for >85°C ambient due to rapid IR increase; not qualified for automotive. | Only for low-temp, non-automotive applications where leakage is not critical. |
Compared with SBRT10U100CT and SS10100CT, the SBR10100CTB delivers higher surge robustness (80A vs. 60A/none), tighter high-temperature leakage control (0.2mA vs. 0.2mA/2.0mA), and full AEC-Q101 compliance-making it the only choice for thermally demanding automotive and industrial DC-DC outputs.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR10100CTB supports continuous operation from –65°C to +175°C junction temperature. At 10A total current and 25°C ambient, thermal calculations using RθJC = 6°C/W show junction rise of ~60°C, keeping TJ well within limit. Derating curves confirm 5A per leg at +125°C ambient.
Is this device suitable for synchronous rectification circuits?
No-SBR10100CTB is a passive rectifier, not a synchronous MOSFET controller or driver. It functions as a high-performance replacement for Schottky diodes in asynchronous rectification stages. For synchronous designs, a dedicated gate driver IC paired with low-RDS(on) MOSFETs is required.
How does the dual common-cathode configuration affect PCB layout?
The shared cathode (Pin 2) simplifies output routing: both anodes connect to transformer secondary or switch node, while cathode ties directly to output capacitor negative. This reduces loop area and EMI. Recommended pad layout (per Diodes doc #DS31515) uses 5.08×1.10mm thermal pad with 10.41mm X1 dimension for optimal heat transfer.
Does the "CTB" suffix indicate tape-and-reel packaging?
No-the "CTB" suffix denotes the TO263AB package variant and internal process code, not packaging. The base part SBR10100CTB ships in 50-piece tubes; tape-and-reel version is SBR10100CTB-13 (800/reel). Packaging type must be specified separately in ordering.
