Product details
Overview
SBRT20V60CT from Diodes Incorporated is a 20A dual common-cathode Trench Super Barrier Rectifier in TO-220AB package, rated for 60V peak reverse voltage, with max 0.55V forward voltage at 10A/25°C and 0.3mA reverse leakage at 60V/25°C. It serves as a high-efficiency rectifier or freewheel diode in DC-DC converters and AC-DC adapters.
For engineers reviewing the SBRT20V60CT datasheet, SBRT20V60CT pinout, SBRT20V60CT application, or SBRT20V60CT equivalent, key selection criteria include low VF at high current, thermal stability of IR up to +125°C, TO-220AB mechanical robustness, and dual-leg configuration enabling shared cathode topology in synchronous rectification or dual-output supplies.
Technical Context
This device uses Diodes Inc.'s proprietary Trench Super Barrier (SBR) technology to achieve ultra-low forward voltage while maintaining tight control over high-temperature reverse leakage. Its dual common-cathode structure supports independent anode switching with shared thermal path to case.
The TO-220AB package delivers 2.5°C/W typical junction-to-case thermal resistance when mounted on a specified black aluminum heatsink (45mm × 20mm × 12mm), enabling sustained 20A total average output current with proper derating above +50°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in bridge or flyback clamp circuits. |
| IO (per leg) | 10 A - Continuous average forward current rating per anode leg at TA = +25°C; total device rating is 20A with shared cathode. |
| VF (max) | 0.55 V @ IF = 10A, TJ = +25°C - Enables >92% conduction efficiency in 12V-output DC-DC stages at full load. |
| IR (max) | 0.3 mA @ VR = 60V, TJ = +25°C - Low leakage preserves standby power budget and avoids thermal runaway in high-temp environments. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting without thermal interface material for compact industrial power designs. |
| TJ Range | –55°C to +150°C - Supports operation in automotive under-hood and industrial motor drive applications with wide ambient variation. |
Pinout & Package
Package: TO-220AB - Molded plastic case with matte tin-plated terminals, UL 94V-0 flammability rating, 1.85g weight, and lead-free/RoHS-compliant construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first rectifier leg | Accepts AC or switched input; electrically isolated from A2 but shares cathode node. |
| Anode 2 (A2) | Input terminal for second rectifier leg | Enables dual-input or split-phase rectification; identical electrical specs to A1. |
| Cathode (K) | Common output node for both legs | Single low-inductance output path; must be thermally coupled to heatsink for 20A operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF trench architecture | 0.48V typ. @ 10A/25°C - Reduces conduction loss by ≥30% vs. standard Schottky diodes in 5–12V output rails. |
| High-temperature IR stability | 0.10mA max @ 60V/125°C - Prevents thermal runaway during sustained overload or elevated ambient conditions. |
| TO-220AB mechanical robustness | UL 94V-0 molding compound + J-STD-020 Level 1 moisture sensitivity - Ensures reliability in reflow-soldered industrial PCB assemblies. |
| Green compliance | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - Meets IPC-1752A environmental reporting requirements. |
Applications
| DC-DC Converter Secondary Side | AC-DC Adapter Output Stage |
|---|---|
Use Scenario: High-frequency synchronous rectification in 300kHz–1MHz isolated flyback or forward converters delivering 5–24V outputs. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete Schottkys to reduce layout area and parasitic inductance. Use Value: 0.55V VF minimizes I²R losses at 10A per leg, improving full-load efficiency by 1.2–1.8% versus comparable 60V Schottky arrays. | Use Scenario: Output rectification in universal-input (90–264VAC) 36W laptop adapters with active PFC front-end. IC Role / Device Role / Timing Role: Freewheel diode clamping transformer leakage energy and conducting continuous output current during MOSFET off-time. Use Value: Stable 0.3mA IR at 25°C and 0.1mA at 125°C ensures no measurable standby power penalty across temperature range. |
| Industrial Motor Drive Power Supply | Telecom Half-Bridge Rectifier |
Use Scenario: Auxiliary 24V/1A bias supply fed from main DC bus in servo drive inverters operating at –40°C to +85°C ambient. IC Role / Device Role / Timing Role: Blocking diode isolating auxiliary supply from bus transients while supporting cold-start capability. Use Value: –55°C to +150°C operating range and 2.5°C/W RθJC allow direct bolt-down heatsinking without thermal pads in space-constrained enclosures. | Use Scenario: Center-tapped rectifier in 48V telecom brick supplies using push-pull topology with 100kHz switching. IC Role / Device Role / Timing Role: Dual-anode configuration matches center-tapped transformer secondary, eliminating need for external cathode tie. Use Value: Shared cathode reduces PCB copper area by 35% and lowers common-mode EMI vs. two discrete diodes with separate cathode traces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20U60CT | Same TO-220AB package and 60V rating, but optimized for ultra-low VF (0.45V typ. @ 10A/25°C); higher IR (0.5mA @ 60V/25°C). | Better efficiency below 85°C ambient; less suitable for sealed enclosures above 100°C due to elevated leakage. | Select when priority is peak efficiency at room temperature and thermal margin exists. |
| MBR2060CT | Standard Schottky with 60V/20A rating; VF = 0.75V min @ 10A/25°C; IR = 1.0mA @ 60V/25°C. | Higher conduction loss and thermal drift limit use in high-density or high-ambient designs. | Acceptable only where cost is primary constraint and thermal headroom exceeds 40°C. |
Compared with SBRT20U60CT, the SBRT20V60CT trades 0.1V higher VF for 67% lower IR at 125°C-critical for sealed industrial power supplies. Against MBR2060CT, it delivers 27% lower conduction loss and 70% less leakage, justifying its use in thermally constrained telecom and motor drive applications.

FAQ
What is the maximum continuous current per anode leg at +100°C ambient?
At +100°C ambient, the SBRT20V60CT supports 6.2A per leg (12.4A total), based on the forward current derating curve in Figure 5 of DS37053 Rev. 3–2. This assumes use of the specified 45mm × 20mm × 12mm black aluminum heatsink and natural convection cooling.
Is SBRT20V60CT suitable for synchronous rectification control schemes?
Yes - its fast recovery characteristics (no specified trr, but inherent in SBR trench structure) and low stored charge enable use with gate drivers in synchronous rectifier topologies. However, it is not a controlled switch; external MOSFETs are required for true synchronous operation.
Does the TO-220AB package require thermal compound when mounted to a heatsink?
No thermal compound is required per the datasheet test condition (Note 5), which specifies direct mounting to a black aluminum heatsink. However, for production reliability across surface flatness variations, a thin layer of thermally conductive grease or pad is recommended to ensure consistent RθJC performance.
How does the green compliance of SBRT20V60CT differ from standard RoHS?
It meets RoHS 2 (2011/65/EU) and adds halogen- and antimony-free status: <900ppm bromine/chlorine (sum <1500ppm), <1000ppm antimony. This exceeds basic RoHS by restricting flame-retardant additives that complicate PCB recycling and pose processing hazards.
