Product details
Overview
SBR40150CTFP-G from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier rated for 150V peak reverse voltage, featuring low forward voltage (0.77V @ 20A, 125°C), soft fast switching, and ITO-220AB thermally enhanced package. It replaces standard Schottky and fast recovery diodes in high-efficiency AC/DC front-ends and DC/DC secondary-side rectification.
For engineers reviewing the SBR40150CTFP-G datasheet, SBR40150CTFP-G pinout, SBR40150CTFP-G application, or SBR40150CTFP-G equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), high-temperature leakage stability (10mA @ 150V, 125°C), and soft-recovery behavior critical for EMI-sensitive power supplies.
Technical Context
This device integrates two independent 20A rectifying elements in a single ITO-220AB package with common cathode configuration, enabling synchronous or interleaved secondary-side rectification. Its patented Super Barrier structure delivers lower VF than conventional Schottkys while maintaining superior high-temperature IR stability compared to PN junction diodes.
The ITO-220AB package provides electrical isolation (2000VAC terminal-to-heatsink) and improved thermal performance over TO-220AB (RθJC = 4°C/W vs. 2°C/W per leg), supporting higher power density in compact industrial and telecom power designs operating up to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum non-repetitive reverse voltage before breakdown; sets usable input range in 115/230VAC SMPS designs. |
| IO (per leg) | 20 A - Continuous average forward current per anode; supports 40A total dual-leg output in parallel-configured secondary windings. |
| VF @ 20A, 125°C | 0.77 V - Confirmed forward drop at full load and elevated temperature; enables <1.5W conduction loss per leg at 20A. |
| IR @ 150V, 125°C | 10 mA - Reverse leakage under worst-case thermal stress; ensures minimal standby loss in high-voltage hold-up circuits. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting with predictable temperature rise under 40W dissipation. |
| IFSM | 280 A - Non-repetitive surge rating (8.3ms half-sine); withstands cold-start inrush without degradation. |
| TJ Range | –65 to +175 °C - Full operational junction temperature span; qualified for under-hood automotive auxiliary supplies and industrial motor drives. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (2000VAC isolation), optimized for surface-mount heatsinking and high-reliability power conversion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input terminal for first rectifying element | Accepts AC or pulsating DC input; routed to transformer secondary winding or switching node. |
| Pin 2 (Cathode) | Common output node for both rectifiers | Delivers combined DC output; requires low-inductance connection to bulk capacitor and load. |
| Pin 3 (Anode 2) | Input terminal for second rectifying element | Enables dual-phase or center-tapped secondary rectification; electrically isolated from Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier technology | Combines Schottky-like VF with PN-diode-level high-temperature IR stability-no trade-off between efficiency and thermal robustness. |
| Soft, fast switching | Low reverse recovery charge (Qrr not specified but implied by soft recovery curve) reduces EMI and snubber losses in high-frequency converters. |
| ITO-220AB isolation | 2000VAC insulation between terminals and heatsink eliminates need for insulating pads in grounded-chassis systems. |
| Green compound & RoHS | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb); compliant with EU RoHS 2 and IPC-1752A material declarations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-40CPH015 | Same 150V VRRM, 40A IO, TO-247AC package; VF = 0.82V @ 20A, 125°C; no isolation (RθJC = 1.5°C/W). | Higher thermal performance but requires insulated mounting hardware for chassis-grounded designs. | Prefer when maximum power density is critical and isolation can be managed externally. |
| ON Semiconductor MUR460CT | 600V PIV, 40A IO, fast recovery (trr ≈ 60ns); VF = 1.7V @ 20A, 25°C; TO-220AB, non-isolated. | Higher voltage rating but significantly higher VF and switching loss; unsuitable for low-VF optimization. | Select only if 600V blocking is mandatory and efficiency is secondary to cost. |
Compared with VS-40CPH015 and MUR460CT, SBR40150CTFP-G uniquely combines 150V/40A rating, sub-0.8V VF at 125°C, soft recovery, and built-in 2000VAC isolation-making it optimal for space-constrained, thermally demanding, and safety-critical 48V–120V output power stages.

FAQ
What is the difference between SBR40150CTFP-G and SBR40150CT?
SBR40150CTFP-G uses the ITO-220AB package with electrically isolated tab (2000VAC terminal-to-heatsink), while SBR40150CT uses standard TO-220AB without isolation. Both share identical electrical specs, but the "FP" suffix denotes the insulated package, and "-G" indicates halogen/antimony-free green compound.
Can SBR40150CTFP-G replace a standard Schottky rectifier in existing designs?
Yes-if the original design uses a dual common-cathode Schottky in TO-220AB or ITO-220AB. Electrical replacement is direct, but verify thermal interface: ITO-220AB's isolated tab eliminates need for mica washers, and its 4°C/W RθJC may require updated heatsink sizing versus lower-RθJC packages.
Is SBR40150CTFP-G suitable for automotive applications?
It meets AEC-Q101 stress test requirements for discrete diodes and operates up to +175°C, making it suitable for under-hood auxiliary supplies and EV charging control boards. However, it is not AEC-Q100 qualified as a full component, so system-level validation remains the customer's responsibility.
What does "SBR" stand for, and how does it differ from a standard Schottky?
"SBR" stands for Super Barrier Rectifier-a Diodes Incorporated proprietary structure that modifies the Schottky barrier using implanted layers to suppress high-temperature leakage while retaining low forward voltage. Unlike standard Schottkys, SBR devices maintain <10mA IR at 125°C and 150V, enabling reliable operation where conventional Schottkys would fail thermally.
