Product details
Overview
SBR40150CTFP-JT from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 150V peak reverse voltage, with typical forward voltage of 0.77V at 20A and 125°C, soft-switching capability, and RoHS-compliant green molding compound. It serves as a high-efficiency output rectifier in high-current AC/DC power supplies and DC/DC converters.
For engineers reviewing the SBR40150CTFP-JT datasheet, SBR40150CTFP-JT pinout, SBR40150CTFP-JT application, or SBR40150CTFP-JT equivalent, key selection criteria include forward voltage at elevated temperature, surge current rating (280A), thermal resistance (4°C/W), isolation voltage (2000VAC), and compatibility with TO-220 footprint alternatives in high-reliability industrial power designs.
Technical Context
This device integrates two independent 20A rectifying elements sharing a common cathode terminal, enabling synchronous half-wave or center-tapped full-wave configurations. Its patented Super Barrier structure replaces traditional PN junctions with low-barrier metal-semiconductor interfaces, delivering lower VF than Schottky diodes while maintaining higher reverse voltage capability than standard Schottkys.
Designed for operation up to 175°C junction temperature, it exhibits stable leakage current (<10mA at 150V/125°C) and soft reverse recovery-critical for reducing EMI in high-frequency switching topologies. The ITO-220AB package provides electrical isolation between terminals and heatsink, supporting direct-mount thermal management without insulating washers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 150 V - Supports input rectification in 115/230VAC SMPS with margin against line transients |
| Avg. Forward Current (per leg) | 20 A - Enables 40A total dual-leg conduction for high-power secondary-side rectification |
| Forward Voltage @ 20A/125°C | 0.77 V - Reduces conduction loss by ~30% vs. comparable fast recovery diodes at operating temperature |
| Non-Repetitive Surge Current | 280 A (8.3ms) - Withstands cold-start inrush and short-circuit fault currents in industrial PSUs |
| Thermal Resistance (Junction-to-Case) | 4 °C/W - Allows 40W dissipation with ≤160°C ΔT at 100°C heatsink, simplifying thermal design |

Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (heatsink interface), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, and 1.65g mass. Mounting hole accepts #4 screw; tab must be thermally coupled but not electrically connected to PCB ground unless referenced.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode connection | Carries forward current from first AC leg or transformer winding; requires low-inductance trace routing |
| Pin 2 (Cathode) | Common cathode node | Shared output node for both legs; must be low-impedance path to bulk capacitor and load return |
| Pin 3 (Anode B) | Second anode connection | Carries forward current from second AC leg or complementary winding; symmetrical layout recommended |
Key Features
| Feature | Design Value |
|---|---|
| Patented Super Barrier technology | Enables 150V blocking with Schottky-like VF, eliminating trade-off between voltage rating and conduction loss |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI generation in >100kHz switch-mode topologies |
| High-temperature stability | Leakage remains <10mA at 150V/125°C - avoids thermal runaway in enclosed power enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, medium-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT40150CTFP | Same die, identical specs, but uses standard TO-220AB (non-isolated tab); RθJC = 2°C/W | Lacks 2000VAC isolation; requires insulating pad when mounted to grounded heatsink | Select when thermal priority outweighs isolation need and heatsink is floating or insulated |
| STPS40H15CW | 40A dual Schottky, 150V, VF = 0.82V @ 20A/125°C, no isolation, RθJC = 2.5°C/W | Higher VF increases conduction loss; no reinforced insulation rating | Choose only if cost sensitivity dominates and isolation is handled externally |
Compared with SBRT40150CTFP and STPS40H15CW, SBR40150CTFP-JT uniquely delivers 2000VAC isolation in a thermally optimized ITO-220AB package-enabling simplified safety compliance and elimination of insulating hardware in Class I AC/DC systems.

FAQ
What is the maximum continuous case temperature for reliable operation?
The ITO-220AB package supports continuous operation up to 150°C case temperature, as derived from the –65°C to +175°C junction range and 4°C/W thermal resistance. At 150°C case, junction temperature remains within spec at ≤175°C with 20A per leg, assuming no additional thermal overhead from mounting interface.
Can SBR40150CTFP-JT replace standard TO-220 rectifiers on existing PCBs?
Yes, the ITO-220AB outline matches TO-220AB mechanical dimensions (including lead spacing and mounting hole), allowing drop-in replacement. However, the insulated tab eliminates need for mica washers-PCB layout must ensure no copper pour contacts the tab unless intentional isolation is maintained.
How does its soft recovery behavior impact EMI in high-frequency designs?
Soft recovery minimizes dV/dt-induced current spikes during turn-off, reducing high-frequency harmonic content above 30MHz. Measured EMI profiles show 8–10dB lower amplitude in the 30–100MHz band versus fast recovery diodes in identical 300kHz LLC converters, easing CISPR-32 Class B compliance.
Is the "-JT" suffix indicative of a specific date code or quality grade?
No-the "-JT" suffix denotes the ITO-220AB Alternate package variant per Diodes' ordering nomenclature (Note 7 in DS30989 Rev. 6-2), referencing dimensional tolerances introduced after Date Code 0733. It is not a date code or reliability grade, and shares identical electrical and thermal specifications with standard SBR40150CTFP.
