Product details
Overview
SBR30150CT from Diodes Incorporated is a 30A dual common-cathode super barrier rectifier in TO-220AB package, rated for 150V peak reverse voltage, with typical forward voltage of 0.78V at 15A/25°C and 0.82V at 15A/125°C, designed for high-efficiency AC/DC and DC/DC secondary-side rectification in industrial power supplies.
For engineers reviewing the SBR30150CT datasheet, SBR30150CT pinout, SBR30150CT application, or SBR30150CT equivalent, key selection criteria include forward voltage drop at elevated temperature, thermal resistance (RθJC = 2°C/W), surge current rating (200A IFSM), and RoHS-compliant green molding compound compatibility with automated reflow and lead-free assembly.
Technical Context
The SBR30150CT integrates two independent 15A rectifying legs sharing a common cathode terminal, enabling synchronous or interleaved secondary-side rectification in center-tapped or full-wave configurations. Its patented super barrier structure replaces traditional PN junctions with low-resistance metal-semiconductor interfaces, reducing forward conduction loss while maintaining soft reverse recovery.
It operates across –65°C to +175°C junction temperature range, with leakage current limited to 0.1mA at 150V/25°C and 10mA at 150V/125°C. Thermal performance is optimized for mounting on black aluminum heatsinks (37mm × 50mm × 15mm), supporting continuous 30A total output under derated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating margin against voltage transients in 12–48V output rails. |
| IO (per leg) | 15 A - Continuous average forward current per anode leg; supports 30A total device output in dual-leg configuration. |
| VF @ 15A/25°C | 0.78 V - Low conduction loss enables >92% efficiency in 12V/20A SMPS secondaries without active cooling. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO-220AB); allows direct heatsink mounting with minimal thermal interface resistance. |
| IFSM | 200 A - Non-repetitive surge rating (8.3ms half-sine); withstands inrush and short-circuit fault currents in regulated power systems. |
| IR @ 150V/125°C | 10 mA - High-temperature reverse leakage; ensures stable operation in enclosed industrial enclosures up to 85°C ambient. |
Pinout & Package
Package: TO-220AB - Molded plastic case, UL 94V-0 rated, matte tin-plated copper leadframe, 1.85g weight, with isolated tab (electrically connected to cathode) for direct heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First rectifying anode | Accepts AC input from transformer secondary winding; carries up to 15A continuous forward current. |
| Pin 2 (Cathode) | Common cathode node | Output node shared by both legs; electrically tied to metal tab for low-inductance heatsinking and return path. |
| Pin 3 (Anode B) | Second rectifying anode | Accepts complementary-phase AC input; enables full-wave center-tapped rectification with single-output polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Super barrier technology | Replaces PN junction with low-barrier Schottky-like structure, achieving VF < 0.82V at 15A/125°C without fast-recovery trade-offs. |
| Soft switching behavior | Minimizes EMI generation during reverse recovery; eliminates need for snubbers in 100–500kHz flyback and forward converters. |
| High-temperature stability | Leakage remains ≤10mA at 150V/125°C; enables reliable operation in sealed industrial power modules without forced air. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900ppm Br, <900ppm Cl, <1000ppm Sb); compliant with IPC-1752 and EU ELV directives. |
Applications
| Server PSU Secondary Rectification | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: 12V/25A output stage in 80 PLUS Titanium-certified server power supply using center-tapped transformer topology. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier converting transformer secondary AC into regulated DC output; replaces two discrete diodes to reduce layout area and thermal mismatch. Use Value: 0.78V VF at 25°C cuts conduction loss by 35% vs. standard FR307, improving full-load efficiency from 91.2% to 92.8%. | Use Scenario: 48V DC bus clamp and freewheeling path in 3-phase inverter drives for HVAC compressors and pumps. IC Role / Device Role / Timing Role: Freewheeling diode across IGBT collector-emitter; conducts regenerative energy during PWM dead-time and motor deceleration. Use Value: Soft recovery limits voltage overshoot to <200V during 100A/μs current commutation, eliminating need for TVS clamping. |
| Telecom Rectifier Module | Renewable Energy Charge Controller |
Use Scenario: -48V DC output rectification in telecom shelf-mounted rectifier units with natural convection cooling. IC Role / Device Role / Timing Role: Primary output rectifier handling 30A continuous load; mounted directly to chassis via isolated tab for passive thermal management. Use Value: RθJC = 2°C/W enables 175°C max junction temperature at 65°C ambient, meeting GR-902-CORE reliability requirements. | Use Scenario: Battery charging path in off-grid solar charge controllers regulating 24V/30A LiFePO₄ battery banks. IC Role / Device Role / Timing Role: Reverse-polarity protection and charging-current rectification between MPPT converter and battery terminals. Use Value: 10mA IR at 125°C prevents >1.5W standby dissipation in desert-mounted enclosures, preserving battery autonomy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VB30150-GS08 (Vishay) | Same 150V/30A rating but VF = 0.85V @ 15A/25°C; RθJC = 2.5°C/W; TO-220AC package with non-isolated tab. | Requires insulating pad for heatsink mounting; higher VF increases conduction loss by ~9% at full load. | Select when legacy board layout uses non-isolated tab mounting and minor efficiency penalty is acceptable. |
| SS30150 (ON Semiconductor) | 30A Schottky rectifier with VF = 0.72V @ 15A/25°C but VR = 100V only; no 150V rating; TJ max = 150°C. | Not suitable for 150V transient-prone industrial lines; limited to ≤100V nominal outputs. | Choose only for cost-sensitive 48V telecom systems where 100V VR is sufficient and 175°C operation is unnecessary. |
Compared with VB30150-GS08 and SS30150, the SBR30150CT uniquely delivers 150V blocking, 175°C operation, and isolated-tab TO-220AB packaging-enabling robust, high-efficiency rectification in space-constrained industrial and telecom power systems without thermal or voltage derating compromises.

FAQ
Is the SBR30150CT pin-compatible with standard TO-220AB dual-diode rectifiers like MUR3020CT?
No. While both use TO-220AB, SBR30150CT has common-cathode configuration (Anode–Cathode–Anode), whereas MUR3020CT is common-anode (Cathode–Anode–Cathode). PCB layout and transformer phasing must be verified before substitution.
Can the metal tab of SBR30150CT be electrically connected to system ground?
Yes-the tab is internally connected to the cathode terminal (Pin 2). It may be bolted directly to a grounded heatsink, provided the heatsink is isolated from other potentials. No insulating washer is required unless system grounding architecture demands cathode isolation.
What is the maximum recommended PCB copper area for thermal relief when mounting SBR30150CT without a heatsink?
Without external heatsinking, the device supports ≤10A total output with ≥4 in² (2580 mm²) of 2-oz copper on inner and outer layers, connected via ≥8 thermal vias (0.3mm diameter) under the tab. Above 10A, a heatsink is mandatory per Fig. 4 derating curve.
Does the "-G" suffix in SBR30150CT-G indicate a different electrical specification?
No. The "-G" suffix denotes halogen- and antimony-free green molding compound only; all electrical parameters-including VF, VRRM, IFSM, and thermal resistance-are identical to the base SBR30150CT part. RoHS compliance and JEDEC MSL-1 rating remain unchanged.
