Product details
Overview
SBR60A100CT from Diodes Incorporated is a 60A dual common-cathode super barrier rectifier in TO-220AB package, rated for 100V peak reverse voltage, with typical forward voltage of 0.72V at 30A/25°C and 175°C maximum junction temperature-used in high-efficiency AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the SBR60A100CT datasheet, SBR60A100CT pinout, SBR60A100CT application, or SBR60A100CT equivalent, key selection criteria include forward voltage drop at high current, thermal resistance (RθJC = 1.0°C/W), leakage current at elevated temperature, and TO-220AB mechanical compatibility with standard heatsinks.
Technical Context
This dual-leg rectifier integrates two independent 30A-rated super barrier diodes sharing a common cathode terminal, enabling full-wave center-tap or parallel-output configurations. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to reduce VF while maintaining soft recovery and low IR.
Designed for high-temperature operation up to 175°C, it delivers stable forward conduction and sub-75μA leakage at 100V/125°C-critical for unregulated rectifier stages in telecom and industrial SMPS where thermal derating margins are tight.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage each leg withstands without breakdown |
| IO (per leg) | 30 A - Continuous average forward current per anode leg at 25°C ambient with heatsink |
| VF @ 30A, 25°C | 0.72 V - Forward voltage drop per leg, directly reducing conduction loss in high-current rectifiers |
| RθJC | 1.0 °C/W - Thermal resistance from junction to case, enabling efficient heat transfer to external heatsink |
| IR @ 100V, 125°C | 75 μA - Reverse leakage per leg at elevated temperature, minimizing standby power loss |
| TJ max | 175 °C - Maximum allowable junction temperature, supporting operation in sealed or high-ambient enclosures |
| IFSM | 350 A - Non-repetitive surge current rating, handling inrush during cold-start of capacitive-input supplies |
Pinout & Package
Package: TO-220AB, 3-terminal plastic molded case with copper leadframe, matte tin-plated terminals, UL 94V-0 flammability rating, and 1.85g mass. Mounting hole centered on tab for heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifier leg | Accepts AC input phase; electrically isolated from Anode 2 and Cathode |
| Anode 2 (Lead 2) | Input terminal for second rectifier leg | Accepts second AC input phase (e.g., center-tap secondary); isolated from Anode 1 and Cathode |
| Cathode (Tab) | Common output node for both legs | Electrically connected to metal tab; must be insulated from chassis unless referenced to system ground |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Industrial Switch-Mode Power Supplies | Telecom Rectifier Modules |
|---|---|
Use Scenario: Primary-side full-wave rectification in 1–3kW open-frame AC/DC power supplies with center-tapped transformer secondary. IC Role / Device Role / Timing Role: Dual-anode super barrier rectifier providing low-loss DC bus generation with minimal thermal stress. Use Value: 0.72V VF at 30A reduces conduction loss by ~15% vs. comparable Schottky diodes, improving efficiency above 90% at full load. | Use Scenario: Output rectification in -48V telecom DC/DC brick converters operating in 60°C ambient cabinets. IC Role / Device Role / Timing Role: Common-cathode dual rectifier delivering parallel 30A outputs with shared thermal path to heatsink. Use Value: 175°C TJ rating allows sustained 60A total output without derating in sealed enclosures, eliminating need for additional airflow. |
| Server PSU Front-Ends | Motor Drive Auxiliary Supplies |
Use Scenario: High-current auxiliary supply rectification feeding control logic and gate drivers in 3-phase IGBT inverters. IC Role / Device Role / Timing Role: Dual-leg rectifier converting transformer-wound auxiliary AC into regulated +15V/-15V rails. Use Value: Soft switching behavior suppresses voltage spikes during transient load steps, protecting downstream LDOs and optocouplers. | Use Scenario: Unregulated DC bus generation for isolated gate driver supplies in HVAC variable-frequency drives. IC Role / Device Role / Timing Role: Common-cathode configuration enables compact dual-rail rectification from single center-tapped winding. Use Value: RθJC = 1.0°C/W allows direct mounting to aluminum heatsink, achieving <100°C junction rise at 60A continuous with passive cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-60CPH10 | 60A, 100V common-cathode hyperfast rectifier; VF = 0.92V @ 30A, 25°C; higher VF increases conduction loss | Higher reverse recovery charge (Qrr = 120nC vs. SBR60A100CT's ~45nC) raises EMI risk in high-frequency designs | Prefer when legacy layout requires identical TO-220AB footprint but thermal margin permits higher VF |
| ON Semiconductor MUR6010CT | 60A, 100V ultrafast dual diode; VF = 1.1V @ 30A, 25°C; significantly higher forward loss | Slower soft recovery and higher Qrr (180nC) limits use in >100kHz rectifiers without snubbers | Select only if cost sensitivity outweighs efficiency targets and board-level EMI filtering is already implemented |
Compared with VS-60CPH10 and MUR6010CT, the SBR60A100CT delivers lower conduction loss, superior thermal performance (RθJC = 1.0°C/W), and softer switching-making it optimal for high-efficiency, high-density, and thermally constrained rectifier designs.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, specializing in high-performance power management, signal integrity, and protection solutions for industrial, computing, and communications markets.
The SBR® Super Barrier Rectifier product line was developed to replace conventional Schottky and ultrafast diodes in high-current, high-temperature rectification-delivering lower VF than Schottkys and softer switching than PN rectifiers.
FAQ
What is the maximum continuous current rating per leg for SBR60A100CT?
The SBR60A100CT is rated for 30A average forward current per leg at 25°C ambient with proper heatsinking. Total device current is 60A due to dual-leg configuration. Derating is required above 25°C per the forward current derating curve in Figure 3 of DS31385 Rev. 4–2.
Is the metal tab electrically connected to a specific terminal?
Yes-the metal tab is the common cathode terminal, internally bonded to both cathodes of the dual rectifier structure. It is not isolated and must be treated as an active circuit node; electrical isolation from chassis is required unless the cathode is system ground referenced.
How does the SBR60A100CT compare to standard Schottky rectifiers in high-temperature operation?
Unlike standard Schottky diodes-which suffer exponential leakage increase above 125°C-the SBR60A100CT maintains only 75μA leakage at 100V/125°C due to its super barrier architecture. This enables stable operation up to 175°C junction temperature without thermal runaway.
Can SBR60A100CT be used in parallel with another unit for higher current?
No-parallel operation is not recommended. The device lacks built-in current-sharing features such as matched VF or integrated ballast resistors. Uneven thermal coupling and VF mismatch between units would cause current imbalance and potential thermal runaway in one device.
