Product details
Overview
SBR2060CTI from Diodes Incorporated is a 20A dual-leg Super Barrier Rectifier (SBR®) in TO251 package, rated for 60V peak reverse voltage per leg, 0.60–0.70V forward voltage at 10A/25°C–125°C, and 150µA max reverse leakage at 60V/25°C. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters.
For engineers reviewing the SBR2060CTI datasheet, SBR2060CTI pinout, SBR2060CTI application, or SBR2060CTI equivalent, key selection criteria include its low VF stability across temperature, soft switching behavior, TO251 thermal resistance (3°C/W), and dual-leg 10A-per-leg / 20A-total current rating in surface-mount form.
Technical Context
This device implements patented Super Barrier Rectifier (SBR®) technology to achieve lower forward voltage than standard Schottky diodes while maintaining superior high-temperature reverse leakage performance. Its dual-anode common-cathode configuration supports independent per-leg operation with shared thermal path.
Designed for high-frequency switching topologies, it delivers soft recovery with minimal reverse recovery charge (Qrr not specified but implied by "soft, fast switching" claim), enabling reduced EMI in synchronous and non-synchronous buck converters operating up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 48V-input DC-DC stages. |
| IO (per leg) | 10 A - Continuous average forward current per anode leg at TC = 110°C; enables 20A total dual-leg output rectification. |
| VF @ 10A/25°C | 0.60 V - Low conduction loss improves efficiency in high-current, low-voltage outputs (e.g., 3.3V/5V rails). |
| VF @ 10A/125°C | 0.70 V - Stable VF increase <0.1V over 100°C range ensures predictable thermal design margin. |
| IR @ 60V/25°C | 150 µA - Ultra-low leakage preserves standby power integrity in always-on systems. |
| RθJC | 3 °C/W - Low junction-to-case thermal resistance allows direct heatsinking via PCB copper pour in TO251 footprint. |
| TJ Range | –65°C to +150°C - Wide operating temperature supports industrial and automotive under-hood applications. |
Pinout & Package
TO251 (IPAK) surface-mount package with three terminals: two anodes (A1, A2) and one common cathode (K). Molded plastic case meets UL 94V-0 flammability rating; matte tin-plated copper leadframe ensures reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode Leg 1 | Independent input path for first rectifier leg; electrically isolated from A2 except through shared K terminal. |
| A2 | Anode Leg 2 | Independent input path for second rectifier leg; enables dual-output or interleaved converter designs. |
| K | Common Cathode | Single output node for both legs; simplifies PCB layout and thermal management with centralized heat extraction point. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Combines Schottky-like VF with PN-junction-level IR stability-enables 0.60V/10A at 25°C and only 0.70V at 125°C. |
| Soft, Fast Switching | Minimizes voltage overshoot and EMI during turn-off; eliminates need for snubbers in 300–500kHz DC-DC designs. |
| High-Temp Leakage Stability | IR remains ≤30µA at 60V/125°C-critical for maintaining efficiency in thermally constrained enclosures. |
| TO251 Thermal Performance | RθJC = 3°C/W with 2″×2″ Al board-supports >15W continuous dissipation without external heatsink. |
Applications
| Server VRM Output Rectification | Industrial DC-DC Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20U60CT | Same 60V/20A rating, but TO263 package; RθJC = 2.5°C/W; VF = 0.62V @ 10A/25°C. | Requires larger PCB area and different thermal pad layout; better suited for higher-power, forced-air-cooled systems. | Select when thermal budget is tighter and board space permits D2PAK footprint. |
| MBR2060CT | Standard Schottky; VF = 0.75V @ 10A/25°C; IR = 500µA @ 60V/25°C; no soft-switching claim. | Higher conduction loss and leakage reduce light-load efficiency; unsuitable for high-temp ambient designs. | Choose only if cost sensitivity outweighs efficiency and thermal performance requirements. |
Compared with SBRT20U60CT and MBR2060CT, the SBR2060CTI offers optimal balance of low VF, ultra-stable IR, and compact TO251 footprint-making it preferred for space-constrained, thermally demanding DC-DC outputs where soft recovery and RoHS/Green compliance are mandatory.

FAQ
What is the maximum continuous current rating per leg for SBR2060CTI?
The SBR2060CTI is rated for 10A average rectified output current per leg at case temperature TC = 110°C, with a total device rating of 20A. Derating is required above TC = 110°C per Figure 3 in the datasheet, and capacitive loads require 20% current reduction.
Does SBR2060CTI have a specified reverse recovery time (trr) or charge (Qrr)?
No trr or Qrr value is specified in the DS39250 datasheet. Instead, Diodes Incorporated characterizes it as having "soft, fast switching capability," confirmed by typical reverse recovery waveforms in application notes-indicating low stored charge and dV/dt-controlled turn-off without hard snap-back.
Can SBR2060CTI be used in place of a standard Schottky diode like MBR2060CT?
Yes, it is a direct functional replacement with improved performance: lower VF (0.60V vs. 0.75V), lower IR (150µA vs. 500µA), and superior high-temperature stability. No layout change is needed since both use TO251 and share identical pinout (A1/A2/K).
Is the TO251 package of SBR2060CTI compatible with reflow soldering per J-STD-020?
Yes-the matte tin finish on copper leadframe meets MIL-STD-202 Method 208 solderability requirements, and the device is qualified for standard Pb-free reflow profiles (peak 260°C, 20–40 sec), as confirmed by Diodes Incorporated's packaging reliability reports.
