Product details
Overview
SBR40150CTFP from Diodes Incorporated is a 40A dual common-cathode super barrier rectifier in ITO-220AB package, rated for 150V peak repetitive reverse voltage, with typical forward voltage of 0.77V at 20A and 125°C, and thermal resistance of 4°C/W junction-to-case - used in high-efficiency AC/DC front-end rectification for industrial power supplies and server PSUs.
For engineers reviewing the SBR40150CTFP datasheet, SBR40150CTFP pinout, SBR40150CTFP application, or SBR40150CTFP equivalent, key selection criteria include forward voltage drop at elevated temperature, surge current capability (280A IFSM), isolation rating (2000VAC), and RoHS-compliant green packaging with halogen/antimony-free molding compound.
Technical Context
This dual-diode rectifier integrates two independent 20A-rated super barrier elements sharing a common cathode terminal, enabling full-wave center-tap or parallel configurations. Its patented super barrier structure delivers lower VF than Schottky diodes while maintaining higher reverse voltage rating and superior high-temperature leakage stability.
Designed for operation up to +175°C junction temperature, it features soft, fast switching behavior with minimal reverse recovery charge - critical for reducing EMI and improving efficiency in high-frequency switching power converters operating above 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum non-repetitive reverse voltage per leg before breakdown; sets usable input voltage range in 115/230VAC SMPS designs. |
| IO (per leg) | 20 A - Continuous average forward current per diode element at TC = 75°C; supports 40A total device output in dual-leg configuration. |
| IFSM | 280 A - Non-repetitive 8.3ms half-sine surge current; withstands inrush into bulk capacitors without failure. |
| VF @ 20A, 125°C | 0.77 V - Confirmed forward drop under hot operating conditions; enables <1.5W conduction loss per leg at full load. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB package; allows accurate heatsink sizing for 40A thermal management. |
| IR @ 150V, 125°C | 10 mA - Max reverse leakage per leg at rated voltage and max junction temperature; ensures low standby loss in offline converters. |
| VAC Isolation | 2000 V - RMS isolation voltage from terminals to heatsink; satisfies reinforced insulation requirements for Class I AC inputs. |
Pinout & Package
Package: ITO-220AB - insulated TO-220 variant with electrically isolated tab, UL 94V-0 molded plastic body, matte tin-plated copper leadframe, and 1.65g mass. Tab is electrically isolated from all terminals and rated for 2000VAC isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode element | Connects to AC input leg 1; must be routed with low-inductance path for high di/dt switching. |
| Pin 2 (Cathode) | Common cathode node | Shared output node for both diodes; carries full 40A DC output current; requires heavy copper pour and thermal via array. |
| Pin 3 (Anode B) | Anode of second diode element | Connects to AC input leg 2; symmetrical layout required to balance conduction losses between legs. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier Technology | Enables 150V VRRM with VF comparable to 45V Schottky diodes - eliminates need for series-connected Schottkys in medium-voltage rectification. |
| Soft, Fast Switching | Low QRR and controlled reverse recovery minimize voltage overshoot and EMI generation during turn-off in hard-switched PFC and LLC stages. |
| High-Temp Stability | Leakage remains ≤10mA at 125°C and 150V - maintains efficiency and reliability in thermally constrained server PSU modules. |
| Green Molding Compound | Halogen-free (<900ppm Br/Cl) and antimony-free (<1000ppm) - meets IPC-1752a material declaration and EU EcoDesign requirements. |
| Isolated Heatsink Interface | 2000VAC isolation between leads and tab - enables direct mounting to grounded heatsinks without insulating pads in Class I systems. |
Applications
| Server Power Supply Rectification | Industrial AC/DC Front-End |
|---|---|
Use Scenario: High-density 1U/2U server PSUs converting 230VAC input to +12V/+54V intermediate bus using active clamp forward or LLC topology. IC Role / Device Role / Timing Role: Dual common-cathode rectifier conducting full-wave output current after transformer secondary; replaces two discrete TO-220 Schottkys. Use Value: 0.77V VF at 125°C reduces conduction loss by ~1.2W per leg versus standard FRD alternatives, directly improving 80 PLUS Titanium efficiency at 50% load. | Use Scenario: DIN-rail mounted 3kW industrial power supply with universal 85–264VAC input and 24V/100A output. IC Role / Device Role / Timing Role: Primary-side bridge rectifier in voltage-doubler or full-wave configuration feeding boost PFC stage. Use Value: 280A IFSM withstands cold-start inrush into 10,000µF bulk capacitance; 4°C/W RθJC enables compact heatsink design within IP65 enclosure constraints. |
| Telecom Rectifier Module | Renewable Energy Inverter Input Stage |
Use Scenario: -48V telecom rectifier module accepting 208Y/120VAC three-phase input with phase-controlled SCR pre-regulator. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in high-frequency forward converter output stage. Use Value: Soft switching behavior suppresses 30–100MHz EMI peaks measured during CISPR-22 Class B compliance testing, reducing filter component count. | Use Scenario: Grid-tied solar inverter with 600VDC PV string input and transformerless H5 topology. IC Role / Device Role / Timing Role: Anti-parallel freewheeling diode across high-side MOSFETs in H-bridge leg, handling reactive current during zero-crossing commutation. Use Value: 175°C max TJ rating supports operation in unventilated rooftop enclosures; 10mA IR at 125°C prevents thermal runaway during prolonged partial shading events. |
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 |
|---|---|---|---|
| STPS40H15CG | 40A, 150V Schottky in TO-247; VF = 0.82V @ 20A, 125°C; no isolation; RθJC = 2.5°C/W. | Lacks 2000VAC isolation; requires insulating pad on heatsink; higher VF increases conduction loss by ~0.5W per leg. | Select when maximum thermal performance is prioritized over isolation and board space; verify creepage/clearance compliance. |
| VS-40CPH015 | 40A, 150V hyperfast diode in TO-247; VF = 1.15V @ 20A, 25°C; trr = 35ns; RθJC = 1.8°C/W. | Higher VF and slower recovery increase switching loss; no green compound; not halogen-free. | Choose only if cost sensitivity outweighs efficiency and environmental compliance requirements. |
Compared with STPS40H15CG and VS-40CPH015, SBR40150CTFP uniquely combines 2000VAC isolation, halogen-free packaging, and sub-0.8V VF at 125°C - making it optimal for space-constrained, thermally demanding, and regulatory-sensitive AC/DC systems where safety and efficiency are co-prioritized.

FAQ
What is the difference between SBR40150CTFP and SBR40150CT?
The SBR40150CTFP uses the ITO-220AB package with electrically isolated tab rated for 2000VAC isolation, while the SBR40150CT uses the standard TO-220AB package with conductive tab. Both share identical electrical specifications, but only the FP variant enables direct mounting to grounded heatsinks without insulation hardware in Class I safety designs.
Can SBR40150CTFP replace a standard FRD in a PFC boost diode position?
Yes - its 150V VRRM, 280A IFSM, and soft switching behavior make it suitable for continuous conduction mode (CCM) PFC boost diodes up to 2kW. However, verify layout thermal relief: the ITO-220AB's 4°C/W RθJC requires larger copper area than TO-247 FRDs to maintain TJ < 150°C under full load.
Does the "Green" designation affect solderability or reflow profile?
No - the halogen- and antimony-free molding compound meets J-STD-020 moisture sensitivity level 1 (MSL-1) and is compatible with standard SnPb and lead-free reflow profiles (peak 260°C). Matte tin plating on leads ensures reliable wetting per MIL-STD-202, Method 208.
Is the common-cathode configuration mandatory for all applications?
No - the dual-diode structure supports multiple topologies: common-cathode for full-wave rectification, or independent anode-to-cathode use as two separate 20A rectifiers. Pin 2 is exclusively the shared cathode; pins 1 and 3 are isolated anodes, allowing flexible PCB routing for either configuration.
