Product details
Overview
SBR20A200CTB from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 200V peak repetitive reverse voltage, with max 0.86V forward voltage at 10A/25°C and 0.1mA reverse leakage at 200V/25°C. It serves as a high-efficiency rectifier or freewheel diode in DC-DC converters and AC-DC adapters.
For engineers reviewing the SBR20A200CTB datasheet, SBR20A200CTB pinout, SBR20A200CTB application, or SBR20A200CTB equivalent, key selection criteria include its low VF stability across temperature, AEC-Q101 qualification, 180A non-repetitive surge rating, and thermal resistance of 3°C/W (junction-to-case per leg).
Technical Context
This dual-diode rectifier uses patented SBR® technology to deliver superior avalanche ruggedness versus Schottky diodes while maintaining ultra-low forward voltage. Its architecture enables stable reverse leakage up to +175°C junction temperature, mitigating thermal runaway risk in high-power density designs.
The device operates with two independent 10A legs sharing a common cathode terminal, supporting synchronous rectification and bidirectional blocking in half-bridge or center-tapped topologies. Its 24–30ns reverse recovery time supports high-frequency switching up to several hundred kHz in resonant and hard-switched converters.

|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated flyback or forward converters delivering 24–48V/5–10A output. IC Role / Device Role: Dual-leg rectifier replacing two discrete Schottkys to reduce component count and improve layout symmetry. Use Value: 0.14V lower VF than typical 200V Schottky at 10A/125°C cuts conduction loss by ~1.4W total, reducing thermal stress on PCB. | Use Scenario: Output rectification in universal-input (90–264VAC) laptop adapters operating at 100–300kHz. IC Role / Device Role: Freewheel diode in active-clamp or quasi-resonant topologies requiring fast trr and low IR. Use Value: 0.51mA IR max at 200V/125°C prevents thermal runaway during sustained high-temp operation, improving MTBF. |
| Industrial Power Supplies | Automotive On-Board Chargers (OBC) |
Use Scenario: Input rectification stage in 3kW industrial UPS systems with forced-air cooling. IC Role / Device Role: Blocking diode in redundant DC bus architectures requiring high surge immunity. Use Value: 180A IFSM rating supports 10× overload tolerance during capacitor charging transients without degradation. | Use Scenario: Isolated DC-DC stage in 6.6kW OBCs converting battery voltage (200–450VDC) to 12V auxiliary rail. IC Role / Device Role: High-reliability rectifier qualified to AEC-Q101 for under-hood mounting near power electronics. Use Value: Operating range of −65°C to +175°C ensures functionality during cold cranking and engine bay thermal soak. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH02-M3 | 200V, 20A dual common-cathode; VF = 0.82V @ 10A/25°C; trr = 35ns; not AEC-Q101 qualified | Lacks automotive qualification; higher trr increases switching loss above 200kHz | Preferred for cost-sensitive industrial supplies where AEC-Q101 is unnecessary |
| ON Semiconductor MUR2020CT | 200V, 20A ultrafast recovery rectifier; VF = 1.1V @ 10A/25°C; trr = 60ns; no SBR technology | Higher VF increases conduction loss by ~2.5W; slower trr raises EMI filtering burden | Only suitable when avalanche ruggedness is secondary to legacy design compatibility |
Compared with VS-20CPH02-M3 and MUR2020CT, SBR20A200CTB delivers the lowest system-level power loss in thermally constrained, high-reliability applications due to its combination of sub-0.86V VF, 24ns trr, and AEC-Q101 validation - critical for automotive and medical-grade power conversion.

FAQ
What is the maximum junction temperature and how does it affect derating?
The SBR20A200CTB has a maximum junction temperature of +175°C. At ambient temperatures above +75°C, the average output current must be linearly derated from 20A (at TC = +150°C) down to zero at +175°C, per Figure 4 in DS31076. This ensures safe operation under sustained thermal stress without thermal runaway.
Is the exposed pad electrically connected, and how should it be handled in PCB layout?
Yes, the exposed pad is internally connected to the cathode (K) terminal and must be soldered to a minimum 2-inch² copper area using the AP02001 recommended pad layout. This connection provides both low-inductance current return and optimal thermal conduction, achieving the specified RθJC of 3°C/W per leg.
How does SBR® technology differ from standard Schottky and ultrafast rectifiers?
SBR® combines a modified Schottky barrier with a lightly doped drift region to achieve higher VRRM (200V) and superior avalanche capability versus Schottkys, while maintaining lower VF and faster trr than ultrafast PN junction rectifiers like the MUR2020CT - bridging the gap between efficiency and ruggedness.
Can SBR20A200CTB replace a single 20A Schottky in a dual-anode configuration?
No - it is a dual common-cathode device (two anodes, one cathode), not a dual common-anode. Replacing two separate Schottkys requires verifying that both anodes drive independent circuits sharing a common output rail. Interchanging pinouts or polarity will cause immediate failure if misapplied.
