Product details
Overview
SBR20A200CTB-13 from Diodes Incorporated is a 20 A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 200 V peak repetitive reverse voltage, with max 0.86 V forward voltage at 10 A and +25°C, 0.1 mA max reverse leakage at 200 V and +25°C, and 24–30 ns reverse recovery time. It serves as a high-efficiency rectifier or freewheel diode in DC-DC converters and AC-DC adapters.
For engineers reviewing the SBR20A200CTB-13 datasheet, SBR20A200CTB-13 pinout, SBR20A200CTB-13 application, or SBR20A200CTB-13 equivalent, key selection criteria include low VF stability across temperature, AEC-Q101 qualification, TO263AB thermal performance (RθJC = 3°C/W per leg), and rugged avalanche capability versus Schottky alternatives.
Technical Context
This dual-diode rectifier integrates two independent 10 A legs sharing a common cathode terminal, enabling synchronous or interleaved operation in high-current buck or flyback topologies. Its patented SBR® structure delivers lower forward voltage than standard silicon PN diodes while maintaining superior high-temperature reverse leakage control compared to Schottky devices.
The device operates from –65°C to +175°C junction temperature, with thermal resistance of 3°C/W (junction-to-case per leg) when mounted on a 2-inch square Al board using Diodes Inc.'s AP02001 pad layout. Derating curves confirm usable current up to 120 A at TC = +150°C under specified conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage the device blocks without breakdown. |
| IO (Total) | 20 A - Total average rectified output current at TC = +150°C, split across two parallel legs. |
| VF Max | 0.86 V @ 10 A, +25°C - Ensures low conduction loss and cooler thermal operation in high-efficiency power stages. |
| IR Max | 0.1 mA @ 200 V, +25°C - Low leakage supports stable blocking in high-impedance bias networks and reduces standby power loss. |
| trr | 24–30 ns - Fast recovery minimizes switching losses and EMI in high-frequency DC-DC converters (>100 kHz). |
| RθJC | 3 °C/W per leg - Enables high-power dissipation with compact heatsinking in TO263AB surface-mount layout. |
| AEC-Q101 | Qualified - Confirms reliability for automotive-grade power supply modules requiring extended temperature and stress validation. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, thermally enhanced plastic case with exposed anode copper tab; 1.6 g mass; UL 94V-0 flammability rating; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode leg | Carries up to 10 A forward current; electrically isolated from Pin 2; connects to input/high-side node in buck converter. |
| Pin 2 (Anode B) | Anode of second diode leg | Carries up to 10 A forward current; independent of Pin 1; enables dual-phase or redundancy configurations. |
| Pin 3 (Cathode) | Common cathode terminal | Shared return path for both legs; large copper area provides low-inductance, low-resistance output connection and thermal conduction to PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like VF with silicon PN robustness-enables 180 A non-repetitive surge current without avalanche failure. |
| Ultra-low VF at high temperature | 0.72 V @ 10 A, +125°C - maintains efficiency in thermally constrained enclosures (e.g., sealed power adapters). |
| Low IR at elevated temperature | 0.51 mA @ 200 V, +125°C - prevents thermal runaway in high-ambient environments like engine bay power modules. |
| AEC-Q101 qualified | Validated for automotive power conversion including infotainment DC-DC supplies and body control unit auxiliary rails. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
Applications
| DC-DC Converters | AC-DC Adapters |
|---|---|
Use Scenario: High-frequency synchronous buck converter in telecom base station power supply. IC Role / Device Role: Output rectifier replacing Schottky diodes to reduce conduction loss and improve thermal margin. Use Value: 0.86 V VF at 10 A lowers power dissipation by ~0.5 W per leg vs. typical 0.95 V Schottky, reducing heatsink size by 30%. | Use Scenario: Secondary-side rectification in 65 W laptop adapter with 150 kHz switching frequency. IC Role / Device Role: Freewheel diode in active-clamp forward topology. Use Value: 24 ns trr limits switching loss to <15 mW at 150 kHz, enabling >92% full-load efficiency. |
| Automotive Body Control Modules | Industrial Motor Drives |
Use Scenario: 12 V auxiliary rail rectification in AEC-Q101-compliant BCM with ambient up to +105°C. IC Role / Device Role: Blocking diode isolating battery backup from main supply during cold-crank events. Use Value: 0.51 mA IR at +125°C ensures <10 µW leakage-induced voltage droop over 10-year service life. | Use Scenario: Snubber network clamp in 3 kW servo drive IGBT gate driver power stage. IC Role / Device Role: High-reliability clamping diode absorbing turn-off energy spikes. Use Value: 180 A IFSM withstands repeated 120 A transient surges without degradation, extending field lifetime beyond 15 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20A200CTB-13 | Tape-and-reel variant with identical electrical specs and TO263AB package; differs only in packaging format (800/reel vs. tube). | No functional difference; selected for automated SMT placement vs. manual/hand-solder prototyping. | Choose SBRT20A200CTB-13 for high-volume production lines requiring reel-fed pick-and-place. |
| MBR20200CTG | Standard Schottky dual rectifier; higher VF (0.95 V @ 10 A) and worse IR drift above +85°C (1.5 mA @ +125°C). | Acceptable in commercial-grade, lower-temperature applications but not AEC-Q101 qualified. | Select MBR20200CTG only for cost-sensitive, non-automotive designs where thermal derating is feasible. |
Compared with SBRT20A200CTB-13, the SBR20A200CTB-13 offers identical performance in tape-and-reel form; versus MBR20200CTG, it delivers 100 mV lower VF and 3× lower high-temp leakage-critical for automotive and high-density power supplies.

FAQ
What is the maximum continuous current per anode leg at +150°C case temperature?
The SBR20A200CTB-13 supports 10 A average rectified current per anode leg at TC = +150°C, as confirmed in the "Maximum Ratings" table. Total device current is 20 A due to dual-leg configuration. Derating is required above +150°C per Figure 4 in DS31076 Rev. 8-2.
Is the TO263AB package lead-free and RoHS compliant?
Yes-the SBR20A200CTB-13 uses matte tin annealed over copper leadframe and green molding compound, fully compliant with EU RoHS Directive 2011/65/EU and halogen/antimony-free requirements (<900 ppm Br+Cl, <1000 ppm Sb). Certification is documented in Diodes Inc.'s quality portal.
How does the SBR20A200CTB-13 differ from standard Schottky rectifiers in thermal performance?
Unlike Schottky diodes, the SBR20A200CTB-13 exhibits minimal reverse leakage increase with temperature-0.51 mA at +125°C versus >1.5 mA for comparable Schottkys. This suppresses thermal runaway risk and enables stable operation in sealed, high-ambient environments without forced cooling.
Can this device be used in place of a single 20 A Schottky in a TO220 package?
No-SBR20A200CTB-13 is a dual common-cathode device in TO263AB, not a single-anode 20 A part. Its 10 A per leg rating requires circuit redesign if replacing a single 20 A TO220 Schottky. Also, TO263AB has different thermal and mounting characteristics than TO220, necessitating PCB layout revision.
