Product details
Overview
SBR40100CTFP-JT from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 100V peak reverse voltage, with typical forward voltage of 0.68V at 20A and 125°C, soft-switching capability, and RoHS-compliant green molding compound. 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 SBR40100CTFP-JT datasheet, SBR40100CTFP-JT pinout, SBR40100CTFP-JT application, or SBR40100CTFP-JT equivalent, key selection criteria include forward voltage drop at elevated temperature, surge current rating (280A), thermal resistance (4°C/W junction-to-case), leakage current at 125°C (≤10mA), and ITO-220AB isolation voltage (2000VAC).
Technical Context
This dual-diode rectifier integrates two independent 20A legs in a single ITO-220AB thermally enhanced package with electrically isolated tab, enabling use in center-tapped transformer configurations or parallel-leg designs. Its patented Super Barrier technology replaces traditional PN junctions with low-barrier metal-semiconductor interfaces, reducing forward conduction loss while maintaining fast, soft recovery behavior.
The device operates across –65°C to +175°C junction temperature range and supports high-frequency switching up to 100kHz without significant reverse recovery tail current. Its 2000VAC isolation between terminals and heatsink allows direct mounting to grounded chassis without insulating hardware in offline SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in bridge or flyback secondary circuits. |
| IO (per leg) | 20 A - Continuous average forward current per diode element at TC = 100°C; total device rating is 40A with shared cathode. |
| VF @ 20A, 125°C | 0.68 V - Confirmed forward voltage under worst-case thermal condition; enables <1.4W conduction loss per leg at full load. |
| IFSM | 280 A - Non-repetitive surge current handling for 8.3ms half-sine; supports inrush tolerance in high-capacitance output stages. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB; enables 130°C max junction rise over 45°C heatsink in 20A operation. |
| IR @ 100V, 125°C | 10 mA - Maximum reverse leakage per leg at full voltage and high temperature; limits standby power loss in energy-sensitive systems. |
| VAC (isolation) | 2000 V - RMS isolation voltage from terminals to heatsink (3 sec); eliminates need for mica washers in grounded-chassis designs. |
Pinout & Package
Package: ITO-220AB - Thermally optimized variant of TO-220 with electrically isolated metal tab, UL 94V-0 molded plastic body, matte tin-plated copper leadframe, and 1.65g mass. Designed for vertical heatsink mounting with screw-hole anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first diode element | Connects to transformer secondary or switch node; carries full 20A forward current during conduction phase. |
| Pin 2 (Cathode) | Common cathode connection | Shared output node for both diodes; must be routed with low-inductance, high-current PCB trace or busbar. |
| Pin 3 (Anode 2) | Anode of second diode element | Enables dual-leg rectification (e.g., center-tapped full-wave); electrically independent from Pin 1 except at cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier technology | Replaces PN junction with low-barrier Schottky-like structure, achieving VF reduction vs. standard Schottky while retaining higher VRRM than conventional SiC Schottky. |
| Soft, fast switching | No reverse recovery tail current; eliminates snubber losses and EMI spikes in high-frequency converters (>50kHz). |
| High-temperature stability | Forward voltage increases only ~0.2mV/°C from 25°C to 125°C; maintains efficiency across wide ambient range. |
| Green molding compound | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); meets IPC-1752A Class 3 material declaration requirements. |
| Lead-free & RoHS compliant | Matte tin finish on Cu leadframe; fully compliant with EU Directive 2011/65/EU and exemptions applied per Diodes Inc. policy. |

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 |
|---|---|---|---|
| STPS40H100CG | 40A dual common-cathode Schottky; VF = 0.75V @ 20A, 125°C; no isolation rating; TO-247AC package. | Lacks 2000VAC terminal-to-tab isolation; requires insulating hardware for grounded heatsinks. | Select when isolation is unnecessary and lower-cost TO-247 mounting is preferred. |
| MBR40100CT | 40A dual Schottky; VF = 0.82V @ 20A, 25°C; degrades to ~0.95V at 125°C; TO-220AB package; no isolation. | Higher VF at elevated temperature increases conduction loss by >40% vs. SBR40100CTFP-JT at 125°C. | Select only for cost-sensitive, non-isolated, low-ambient-temperature applications. |
Compared with STPS40H100CG and MBR40100CT, SBR40100CTFP-JT delivers superior thermal stability, lower high-temperature VF, and integrated isolation-making it optimal for space-constrained, grounded-chassis, high-reliability power systems where thermal margin and safety certification matter.

FAQ
What is the difference between SBR40100CTFP-JT and SBR40100CTFP?
SBR40100CTFP-JT uses the ITO-220AB (Alternate) mechanical outline per DS30988 Rev. 6 Note 7, with dimensional tolerances updated for Date Code 0733 and newer. The "-JT" suffix denotes this alternate ITO-220AB variant, which retains identical electrical specs, thermal resistance, and isolation rating but features tighter dimensional control on A, A1, D, and L1 dimensions per the datasheet's ITO-220AB Alternate table.
Can SBR40100CTFP-JT replace a standard TO-220AB rectifier in existing layouts?
Yes, but only if the PCB footprint and heatsink mounting accommodate ITO-220AB dimensions: 15.80–16.20mm L1 length and 9.87–10.67mm L height. Unlike TO-220AB, ITO-220AB has an electrically isolated tab-no insulator is needed-but mechanical cutouts and screw-hole alignment must match the alternate outline specified in the datasheet's "ITO-220AB Alternate" table.
Is the 2000VAC isolation rating tested per industry standard?
Yes-the 2000VAC isolation (t = 3 sec.) is measured per IEC 60747-5-2 between all terminals (Pins 1 & 3) and the metal tab (heatsink interface). This rating is validated during 100% production testing and applies only to the ITO-220AB package variant; TO-220AB versions lack this isolation feature entirely.
How does SBR40100CTFP-JT perform at 150°C junction temperature?
At TJ = 150°C, VF rises to ≤0.73V @ 20A (per datasheet Typ value), IR remains ≤5mA @ 100V, and thermal resistance holds at 4°C/W. Derating curves confirm 15A average current per leg is sustainable at TC = 100°C, making it suitable for sealed, high-ambient environments like enclosed industrial drives or base station power modules.
