Product details
Overview
SBR4060CTFP-JT from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier rated for 60V peak reverse voltage, featuring low forward voltage (0.65V typ. at 20A, 125°C), soft fast switching, and ITO-220AB package with isolated heatsink mounting. It serves as a high-efficiency output rectifier in AC/DC and DC/DC power supplies for telecom and industrial equipment.
For engineers reviewing the SBR4060CTFP-JT datasheet, SBR4060CTFP-JT pinout, SBR4060CTFP-JT application, or SBR4060CTFP-JT equivalent, key selection criteria include forward voltage drop at elevated temperature, thermal resistance to heatsink (4°C/W), isolation voltage rating (2000 VAC), and RoHS-compliant green compound construction.
Technical Context
This dual-diode rectifier integrates two independent SBR (Super Barrier Rectifier) die in a single ITO-220AB package with electrically isolated tab, enabling synchronous or interleaved output configurations. Its patented barrier structure delivers lower VF than Schottky diodes while maintaining superior high-temperature leakage performance.
The device operates across –65°C to +150°C junction temperature range and supports 280A non-repetitive surge current (8.3ms half-sine). Its soft recovery minimizes EMI in high-frequency switching converters, and the 2000 VAC isolation allows direct mounting to grounded heatsinks without insulating hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 60 V - Maximum blocking voltage per leg; defines maximum input/output differential in bridge or flyback secondary designs. |
| Avg. Forward Current (per leg) | 20 A - Continuous DC current capability per diode at TA = 25°C with adequate heatsinking. |
| Total Device Current | 40 A - Combined output capacity when both legs used in parallel or split-rail configuration. |
| Forward Voltage (VF) | 0.65 V @ 20A, 125°C - Enables <1.3W conduction loss per leg at full load and high ambient, reducing thermal stress. |
| Thermal Resistance (RθJC) | 4 °C/W - Junction-to-case value for ITO-220AB; determines minimum heatsink requirement for 150°C max TJ operation. |
| Isolation Voltage | 2000 VAC - Withstands 3s AC test between terminals and heatsink; eliminates need for mica washers or sil-pads in chassis-grounded systems. |
| Leakage Current (IR) | 100 µA @ 60V, 125°C - Confirms stable blocking behavior under worst-case thermal stress, critical for standby efficiency. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated metal tab (heatsink interface), UL 94V-0 molded plastic body, matte tin-plated copper leadframe, 1.65g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode | Connects to transformer secondary or switch node; carries full forward current during conduction phase. |
| Pin 2 (Cathode) | Common cathode | Output node shared by both diodes; routed to bulk capacitor or regulator input; must handle combined 40A ripple current. |
| Pin 3 (Anode B) | Anode of second diode | Enables dual-output or center-tapped transformer rectification; electrically independent from Pin 1 except at cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Patented Super Barrier technology | Combines Schottky-like low VF with PN-junction thermal stability-0.65V @ 20A/125°C and only 100µA IR at same condition. |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI generation in >100kHz SMPS, easing filter design and meeting CISPR-22 Class B limits. |
| 2000 VAC isolation | Allows direct bolt-down to grounded metal chassis without insulation hardware-reducing assembly cost and thermal interface resistance. |
| Halogen- and antimony-free "Green" compound | Meets IEC 61249-2-21: <900ppm Br, <900ppm Cl, <1000ppm Sb-ensures compliance in EU automotive and industrial end-equipment. |
Applications
| Telecom Power Supply | Industrial DC/DC Converter |
|---|---|
Use Scenario: 48V input rectification in distributed power architecture (DPA) brick modules delivering ±12V/±5V rails. IC Role / Device Role / Timing Role: Dual-leg output rectifier handling 20A per rail with shared cathode return path.

IC Role / Device Role / Timing Role: High-current freewheeling and synchronous rectification element in active clamp forward topology. Use Value: 4°C/W RθJC enables 150°C max junction temp with 37×50×15mm heatsink-eliminating need for oversized thermal solution. |
| Server PSU OR-ing Circuit | Renewable Energy Inverter Auxiliary Supply |
Use Scenario: OR-ing diode array in redundant 12V server backplane power distribution, paralleling multiple PSUs. IC Role / Device Role / Timing Role: Low-VF, high-current blocking diode preventing reverse current flow during PSU failure or hot-swap events. Use Value: 0.61V VF at 25°C ensures <12.2W dissipation per diode at 20A-cutting thermal load vs. 0.75V alternatives and enabling higher density layout. | Use Scenario: Auxiliary 24V supply rectification in solar string inverters, operating continuously at 65°C ambient inside sealed enclosures. IC Role / Device Role / Timing Role: Input-stage rectifier converting transformer-wound auxiliary AC to regulated DC for gate drivers and MCU. Use Value: Stable 100µA IR at 125°C prevents thermal runaway under sustained high-temp operation-extending service life beyond 10 years MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-temperature rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT40U60CT | Same 60V/40A rating but TO-263 (D²PAK) package; RθJC = 3.5°C/W; no isolation. | Requires insulated mounting hardware for heatsink attachment; better suited for PCB-mounted, space-constrained designs. | Select when board area is limited and isolation can be managed via pad cutouts or thermal pads. |
| MBR4060CT | Standard Schottky; VF = 0.75V @ 20A/25°C; IR = 20mA @ 60V/125°C; TO-220AB (non-isolated). | Higher conduction loss and thermal instability limit use to lower ambient or derated loads. | Select only for cost-sensitive, non-isolated, <85°C ambient applications where leakage is not critical. |
Compared with SBRT40U60CT and MBR4060CT, SBR4060CTFP-JT uniquely combines ITO-220AB isolation, industry-leading VF at high temperature, and ultra-low high-temp leakage-making it optimal for thermally demanding, safety-critical, or chassis-grounded power systems.

FAQ
What is the difference between SBR4060CTFP-JT and SBR4060CTFP?
SBR4060CTFP-JT uses the ITO-220AB (Alternate) mechanical outline per DS30987 Rev. 6–2 Note 8, applicable to products manufactured before Date Code 0733. It retains identical electrical specs, thermal resistance (4°C/W), and 2000 VAC isolation, but has minor dimensional variances in A, A1, A2, D, D1, and L1 versus the standard ITO-220AB footprint.
Can SBR4060CTFP-JT replace a standard TO-220AB Schottky in existing designs?
Yes-if the PCB layout accommodates ITO-220AB's isolated tab and mounting hole pattern. Electrical replacement is valid due to identical voltage/current ratings and lower VF, but thermal design must account for 4°C/W RθJC (vs. ~2°C/W for TO-220AB), and no insulator is needed thanks to 2000 VAC isolation.
Why does SBR4060CTFP-JT specify "Green" and halogen-free?
It meets IEC 61249-2-21 requirements: <900ppm bromine, <900ppm chlorine (<1500ppm total Br+Cl), and <1000ppm antimony. This supports environmental compliance in EU industrial and automotive end-equipment and improves combustion safety during recycling or fire events.
How is the 2000 VAC isolation verified and applied in practice?
Per datasheet, isolation is tested for 3 seconds at 2000 VAC between all terminals and the heatsink-mounting surface. In practice, this allows direct metal-to-metal contact with grounded chassis-eliminating mica/sil-pad interfaces, reducing thermal resistance by ~0.8°C/W, and simplifying mechanical assembly in telecom rectifiers and server PSUs.
