Product details
Overview
SBR30A150CTFP from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 150V peak reverse voltage, with typical forward voltage of 0.74V at 15A/25°C and 0.67V at 15A/125°C, used in high-efficiency AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the SBR30A150CTFP datasheet, SBR30A150CTFP pinout, SBR30A150CTFP application, or SBR30A150CTFP equivalent, key selection criteria include forward voltage drop at elevated temperature, thermal resistance (4°C/W junction-to-case), soft switching behavior, RoHS/Green compliance, and isolation rating (2000VAC).
Technical Context
This device integrates two independent anode terminals sharing a common cathode, enabling dual-phase or parallel rectification paths. Its patented Super Barrier structure replaces traditional PN junctions with low-barrier metal-semiconductor interfaces, reducing forward conduction loss while maintaining high-temperature leakage stability.
It operates across –65°C to +175°C junction temperature range and delivers soft, fast recovery (no data on trr but characterized by low reverse recovery charge per application notes), making it suitable for high-frequency switching topologies where diode reverse recovery impacts EMI and efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in bridge or center-tap configurations. |
| IO (per leg) | 15 A - Continuous average forward current per anode leg at TA = 25°C; total device rating is 30A with shared cathode. |
| VF @ 15A/25°C | 0.74 V - Measured forward voltage drop determines conduction loss (11.1W per leg) and thermal design margin. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB package; enables direct heatsink mounting for high-power dissipation. |
| IR @ 150V/125°C | 10 mA - Max reverse leakage per leg at max rated voltage and high temperature; critical for standby power and thermal runaway avoidance. |
| VAC (Isolation) | 2000 V - AC isolation voltage between terminals and heatsink; required for safety-certified industrial power supplies. |
| IFSM | 250 A - Non-repetitive surge current capability supports inrush handling during cold start without degradation. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (heatsink interface), UL 94V-0 molded plastic body, matte tin-plated copper leadframe, 1.65g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode input | Accepts AC phase or transformer secondary winding; electrically isolated from heatsink. |
| Pin 2 (Cathode) | Common cathode output | Shared DC output node for both rectifier legs; connects to bulk capacitor positive rail. |
| Pin 3 (Anode B) | Second anode input | Accepts second AC phase or complementary winding; independent conduction path from Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier technology | Replaces PN junction with low-barrier Schottky-like structure, achieving VF < 0.88V at 15A/25°C without excessive leakage. |
| Soft switching capability | Minimizes voltage overshoot and EMI during turn-off, verified via oscilloscope waveforms in Diodes app note AN-4001. |
| High-temperature stability | Leakage remains ≤10mA at 150V/125°C - enables reliable operation in enclosed, convection-cooled enclosures. |
| Green / Halogen-free construction | Meets <900ppm Br, <900ppm Cl, <1000ppm Sb thresholds; supports environmental compliance for EU and global OEM programs. |
| Isolated heatsink interface | 2000VAC isolation allows direct mounting to grounded chassis without insulating hardware or thermal pads. |
Applications
| Industrial AC/DC Power Supply | Server PSU Front-End Rectification |

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 |
|---|---|---|---|
| STPS30H150CG | Same 150V/30A rating, but uses standard Schottky architecture; higher VF (0.82V typ @ 15A) and lower max TJ (175°C same). | Lacks 2000VAC isolation; requires insulating hardware for heatsink mounting. | Select when cost sensitivity outweighs isolation and VF advantage; verify thermal design with RθJC = 3.5°C/W. |
| Vishay VS-30CPH015 | 150V/30A common-cathode planar diode; VF = 0.92V @ 15A/25°C; higher leakage (50mA @ 150V/125°C). | No isolation rating; not qualified for Green/Halogen-free compliance. | Prefer only in legacy designs where footprint compatibility with TO-247 is required and environmental specs are waived. |
Compared with STPS30H150CG and VS-30CPH015, SBR30A150CTFP offers superior forward voltage, certified isolation, and halogen-free construction-making it optimal for new industrial and renewable energy designs requiring efficiency, safety, and regulatory compliance.

FAQ
What is the difference between SBR30A150CTFP and SBR30A150CT?
The SBR30A150CTFP uses the ITO-220AB package with electrically isolated tab (2000VAC isolation), while the SBR30A150CT uses standard TO-220AB without isolation. Both share identical electrical specs, but CTFP enables direct grounded heatsink mounting without insulators, simplifying mechanical design and improving thermal reliability.
Can SBR30A150CTFP be used in place of a standard 30A bridge rectifier?
No - it is a dual-anode/common-cathode configuration, not a full bridge. It replaces two discrete diodes in center-tapped or dual-phase rectifiers. To substitute a 4-pin bridge, external wiring and layout changes are required; it does not offer built-in AC1/AC2/+/– terminals.
What is the maximum allowable case temperature during operation?
The absolute maximum case temperature is not directly specified, but the device's 175°C max junction temperature and 4°C/W RθJC imply a max case temperature of 175°C under zero ambient rise. In practice, derating curves show 15A per leg is sustainable up to 100°C ambient with adequate heatsinking - corresponding to ~140°C case temperature.
Does SBR30A150CTFP require snubber circuits in high-frequency SMPS designs?
Snubbers are typically unnecessary due to its soft, low-Qrr switching behavior - confirmed in Diodes' AN-4001 - which suppresses voltage ringing. However, layout parasitics may still demand localized RC damping in >100kHz LLC or phase-shifted full-bridge topologies; empirical validation with oscilloscope probing is recommended.
