Product details
Overview
SBR30A100CTB from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 100V peak repetitive reverse voltage, with typical forward voltage of 0.78V at 15A/25°C and 0.85V at 15A/125°C, enabling high-efficiency DC-DC output rectification in automotive power supplies.
For engineers reviewing the SBR30A100CTB datasheet, SBR30A100CTB pinout, SBR30A100CTB application, or SBR30A100CTB equivalent, key selection criteria include its 180A non-repetitive surge rating, 480mJ avalanche energy capability, low thermal resistance (3°C/W per leg), and AEC-Q101 qualification for under-hood reliability.
Technical Context
This dual common-cathode rectifier integrates two independent 15A-rated SBR elements sharing one cathode terminal, leveraging patented Trench SBR® technology to deliver superior avalanche ruggedness versus Schottky diodes while maintaining ultra-low VF. Its soft, fast switching minimizes EMI in high-frequency SMPS designs.
The device operates across –65°C to +150°C junction temperature range, with thermal resistance of 3°C/W (junction-to-case per leg) and 16°C/W (junction-to-ambient on FR-4 PCB), supporting high-power density layouts where thermal management is critical in automotive and industrial power converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage per leg; defines safe operating margin in 48V automotive systems. |
| IO (per leg) | 15 A - Continuous DC current rating per anode-cathode path at TC = +150°C; supports 30A total dual-leg output. |
| VF @ 15A/25°C | 0.78 V - Low conduction loss enabling >95% efficiency in 12V–48V output stages. |
| IR @ 100V/125°C | 10 µA - Ultra-low high-temp leakage prevents thermal runaway in hot under-hood environments. |
| IFS M | 180 A - 8.3ms half-sine surge rating; withstands load dump transients without failure. |
| EAS | 480 mJ - Avalanche energy handling per element; enables robust operation during inductive switching events. |
| RθJC (per leg) | 3 °C/W - Enables direct heatsinking via D2PAK tab; simplifies thermal design in space-constrained modules. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, thermally enhanced plastic case with exposed copper tab for heatsinking. RoHS-compliant, halogen-free "Green" variant available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input terminal for first rectifier element | Accepts AC or switched input; electrically isolated from Anode 2. |
| Anode 2 (Pin 2) | Input terminal for second rectifier element | Enables dual-channel or parallel configuration; shares cathode with Pin 1 element. |
| Cathode (Tab / Pin 3) | Common output node for both rectifier elements | Exposed metal tab serves as primary thermal path and electrical connection; must be soldered to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Trench SBR® technology | Delivers 480mJ avalanche energy and 180A surge rating-exceeding standard Schottky limits while retaining low VF. |
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock testing. |
| Soft, fast switching | Reduces reverse recovery ringing and EMI generation in 100–500kHz DC-DC converters. |
| Low RθJC (3°C/W per leg) | Allows >20W dissipation per element with minimal ΔT; eliminates need for external heatsinks in many applications. |
| Halogen- and antimony-free "Green" option | Meets EU Directive 2015/863/EU with Br+Cl <1500ppm and Sb <1000ppm; supports sustainability compliance programs. |
Applications

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-30CPH01-M3 | Same 100V/30A rating, but uses standard SBR (not Trench); lower EAS (320mJ) and higher VF (0.87V @15A/25°C). | Lacks AEC-Q101 qualification; suitable for industrial but not automotive under-hood deployment. | Prefer when cost sensitivity outweighs surge robustness and automotive compliance requirements. |
| ON Semiconductor NRVB30100CTT4G | 100V/30A Schottky with VF = 0.82V @15A/25°C, but no avalanche rating and IR = 100µA @125°C. | No avalanche capability; unsuitable for inductive load switching or load-dump transient conditions. | Select only in benign thermal environments (<85°C) with no surge exposure and strict VF budget. |
Compared with VS-30CPH01-M3 and NRVB30100CTT4G, SBR30A100CTB delivers superior thermal stability (10× lower IR at 125°C), certified automotive ruggedness, and 50% higher avalanche energy-making it the sole choice for safety-critical 48V automotive power conversion where reliability trumps marginal cost savings.

FAQ
What is the thermal performance difference between SBR30A100CTB and standard Schottky diodes at 125°C?
At 125°C and 100V reverse bias, SBR30A100CTB exhibits only 10µA leakage current-10× lower than typical Schottky diodes (e.g., NRVB30100CTT4G at 100µA). This directly suppresses thermal runaway risk in enclosed automotive modules where ambient temperatures exceed 85°C and airflow is restricted.
Can SBR30A100CTB be used in parallel configurations for >30A applications?
Yes-its matched dual-element structure and low thermal resistance (3°C/W per leg) enable balanced current sharing when mounted on symmetric copper pours. Derating to 13A per leg is recommended for sustained >26A operation to maintain TJ ≤150°C with standard 2oz FR-4 layout.
Does the TO263AB package require special PCB layout considerations?
Yes-the exposed cathode tab must be connected to ≥4 cm² of 2oz copper with ≥6 thermal vias (0.3mm diameter, spaced ≤2mm apart) to achieve the rated 3°C/W RθJC. Minimum pad dimensions per Diodes' outline DWG-000122 must be followed to ensure mechanical reliability and solder joint integrity.
Is SBR30A100CTB suitable for synchronous rectification replacement?
No-it is a passive rectifier, not a synchronous MOSFET controller or driver. However, its 0.78V VF at 15A/25°C provides competitive conduction loss vs. many discrete MOSFETs in <300kHz applications, making it a viable drop-in alternative where gate drive complexity or body diode reverse recovery must be avoided.
