Product details
Overview
SBRT30A100CT from Diodes Incorporated is a 30A dual common-cathode Trench Super Barrier Rectifier (SBR) rated for 100V peak repetitive reverse voltage, with max 0.8V forward voltage at 15A/25°C and 0.15mA reverse leakage at 100V/25°C, designed for high-efficiency DC-DC output rectification in industrial power supplies.
For engineers reviewing the SBRT30A100CT datasheet, SBRT30A100CT pinout, SBRT30A100CT application, or SBRT30A100CT equivalent, key selection criteria include low VF stability across temperature, AEC-Q101 qualification, TO220AB package thermal resistance (1°C/W), and dual-leg parallel current handling up to 30A total.
Technical Context
This dual-diode rectifier integrates two independent 15A-rated SBR chips in a single TO220AB package with common cathode configuration, enabling synchronous-like efficiency without gate drive complexity. Its trench-based super barrier architecture delivers lower VF than Schottky diodes while maintaining superior high-temperature IR stability versus standard PN junctions.
Designed for continuous conduction mode (CCM) operation in secondary-side rectification, it supports 200A non-repetitive surge current per leg and exhibits 16W maximum average forward power dissipation at TC = 25°C, derating linearly to zero at 150°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum allowable reverse voltage before breakdown; defines safe blocking capability in 48V–60V bus applications. |
| IO (per leg) | 15 A - Continuous DC current rating per diode; enables 30A total output when both legs used in parallel. |
| VF max | 0.80 V @ 15A, 25°C - Low conduction loss improves system efficiency and reduces heatsink requirements. |
| IR max | 0.15 mA @ 100V, 25°C - Ultra-low leakage ensures stable performance in high-temp environments (e.g., automotive under-hood). |
| RθJC | 1 °C/W - Junction-to-case thermal resistance with standard heatsink; allows precise thermal design for 30A operation. |
| IFSM | 200 A @ 8.3ms - Surge rating supports inrush and transient overload conditions without failure. |
| TJ range | −55°C to +150°C - Extended operating temperature supports industrial and automotive under-hood deployment. |
Pinout & Package
Packaged in industry-standard TO220AB (lead-free, RoHS-compliant) with insulated tab; thermally optimized for bolt-down heatsinking. Pin configuration: Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Leg 1 | Input terminal for first rectifier path; connects to transformer secondary or switching node. |
| Pin 2 | Common Cathode | Shared output node for both legs; routed to output capacitor and load return path. |
| Pin 3 | Anode of Leg 2 | Input terminal for second rectifier path; enables dual-phase or redundancy configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.67V typ @ 15A/125°C - Maintains high efficiency even at elevated temperatures, reducing thermal stress. |
| High-temp IR stability | 30mA max @ 100V/125°C - Prevents thermal runaway in compact, sealed enclosures. |
| AEC-Q101 qualified | Qualified for automotive-grade reliability - meets stress test requirements for vibration, temperature cycling, and HTRB. |
| Green compound | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) - complies with environmental directives and soldering standards. |
Applications
| Server Power Supply | Industrial Motor Drive |

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 |
|---|---|---|---|
| SBRT30A100CTFP | Same die, ITO220AB package with insulated tab; RθJC = 3.3°C/W vs. 1°C/W in TO220AB. | Preferred where electrical isolation from heatsink is required; trade-off is higher thermal resistance. | Select CTFP for isolated mounting; select CT for maximum thermal performance with grounded heatsink. |
| MBR30H100CT | Standard Schottky; VF = 0.92V min @ 15A/25°C; IR = 2mA @ 100V/25°C - higher conduction loss and leakage. | Suitable for cost-sensitive, lower-temp applications where 150°C operation not needed. | Choose MBR30H100CT only if thermal budget allows higher VF and leakage; avoid above 100°C ambient. |
Compared with SBRT30A100CTFP, the CT version offers 69% lower thermal resistance for identical power dissipation; versus MBR30H100CT, it delivers 15% lower VF and 93% less IR at 125°C - critical for high-reliability, high-temperature deployments.

FAQ
What is the difference between SBRT30A100CT and SBRT30A100CTFP?
The SBRT30A100CT uses a TO220AB package with electrically conductive tab, offering 1°C/W junction-to-case thermal resistance. The SBRT30A100CTFP uses an ITO220AB package with electrically insulated tab and higher 3.3°C/W thermal resistance. Both share identical die and electrical specs but differ in mechanical mounting and thermal interface requirements.
Is SBRT30A100CT suitable for automotive applications?
Yes - it is AEC-Q101 qualified and rated for −55°C to +150°C operating temperature. Its low 0.15mA reverse leakage at 25°C and stable 30mA at 125°C make it appropriate for under-hood auxiliary power supplies, provided proper heatsinking and voltage derating are applied per automotive design guidelines.
Can SBRT30A100CT be used in parallel with another unit for 60A output?
No - the device is a dual-leg common-cathode rectifier rated for 30A total (15A per leg). Parallel connection of multiple SBRT30A100CT units is not recommended due to mismatched VF and thermal coupling risks; instead, use higher-current alternatives like SBRT40A100CT or multi-phase designs.
What is the typical junction capacitance at 10V reverse bias?
Per Figure 5 in DS37998 Rev. 3-2, typical junction capacitance is approximately 10,000 pF at VR = 10V and f = 1 MHz. This value decreases with increasing reverse voltage and impacts high-frequency switching noise and EMI filter design in fast-switching topologies.
