Product details
Overview
SBR30A100CTB-13-G 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, designed for high-efficiency DC-DC output rectification in automotive power supplies and industrial SMPS.
For engineers reviewing the SBR30A100CTB-13-G datasheet, SBR30A100CTB-13-G pinout, SBR30A100CTB-13-G application, or SBR30A100CTB-13-G equivalent, key selection criteria include its ultra-low VF, AEC-Q101 qualification, soft-switching behavior, 180A non-repetitive surge rating, and thermal resistance of 3°C/W per leg - critical for thermally constrained 12V/24V/48V system designs.
Technical Context
This dual-diode rectifier integrates two independent SBR® elements sharing a common cathode terminal, enabling synchronous half-wave or center-tapped full-wave configurations. Its patented Trench SBR® technology delivers superior avalanche ruggedness (480mJ EAS, 8kW PARM) compared to Schottky diodes while maintaining low conduction loss.
It operates across -65°C to +150°C junction temperature range with <10µA leakage at 100V/125°C and exhibits soft, fast recovery (no specified trr but characterized by low ringing in switching waveforms), making it suitable for high-frequency flyback and forward converters where reverse recovery noise must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage per diode leg; defines usable input/output voltage range in 48V systems |
| IO (per leg) | 15 A - Continuous DC current per anode-cathode path at TC = +150°C; supports 30A total dual-leg output |
| VF @ 15A/25°C | 0.78 V - Low conduction loss enables >95% efficiency in 12V–48V secondary-side rectification |
| RθJC (per leg) | 3 °C/W - Enables direct heatsinking via PCB copper pour; allows 15A operation with ≤45°C rise above case |
| IFSM | 180 A - Withstands single-cycle inrush surges in automotive cold-crank or hot-swap scenarios |
| EAS | 480 mJ - Avalanche energy rating ensures robustness against inductive switching transients without clamping |
| IR @ 100V/125°C | 10 µA - Ultra-low high-temp leakage prevents thermal runaway in sealed enclosures or under hood environments |
Pinout & Package
TO263AB (D2PAK) surface-mount package with exposed metal tab (cathode-connected) for thermal dissipation and mechanical anchoring. Three terminals: two anodes (A1, A2) and one common cathode (K).

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 |
|---|---|---|---|
| SBRT30A100CTB-13-G | Same die, enhanced thermal pad design; RθJC = 2.5°C/W (vs. 3.0°C/W); 10% lower VF at 15A/125°C | Better suited for convection-cooled 30A designs where <40°C ΔT is required | Select when thermal margin is constrained and board space allows revised footprint |
| MBR30100CTG | Standard Schottky; VF = 0.82V @ 15A/25°C but no avalanche rating; IR = 500µA @ 100V/125°C | Limited to non-automotive, non-inductive-load applications due to lack of EAS/PARM specs | Acceptable only in cost-sensitive, low-reliability consumer SMPS with no surge exposure |
Compared with SBRT30A100CTB-13-G, this part trades 0.5°C/W higher thermal resistance for broader availability and lower cost; versus MBR30100CTG, it provides essential avalanche ruggedness and 50× lower high-temp leakage - decisive for automotive and industrial reliability.

FAQ
Is SBR30A100CTB-13-G pin-compatible with standard TO263AB dual-diode rectifiers?
Yes - it uses the industry-standard TO263AB (D2PAK) outline with identical mechanical dimensions, pad layout, and terminal configuration (A1/A2/K). The pinout matches MBR30xxCT, SBRT30xxCT, and other common-cathode dual-diode packages in the same footprint, enabling drop-in replacement in existing PCB designs.
What is the maximum continuous current per leg at 100°C case temperature?
Per the derating curve in Figure 1, at TC = +100°C, the average forward current per leg is approximately 12.5A. This is derived from linear interpolation between 15A at 150°C and ~18A at 25°C, confirming usable 25A total device current under moderate heatsinking at 100°C case temperature.
Does SBR30A100CTB-13-G require a minimum gate drive or control signal?
No - it is a passive rectifier diode with no control inputs or gate terminals. It operates solely on forward bias conduction and reverse blocking, requiring no external drive circuitry. Its soft switching behavior is inherent to the Trench SBR® structure and does not depend on external timing or gate control.
Can SBR30A100CTB-13-G be used in place of a MOSFET synchronous rectifier?
Yes, in applications where simplicity, cost, and reliability outweigh marginal efficiency gains - particularly where MOSFET gate drive complexity, layout sensitivity, or body diode reverse recovery issues are concerns. It delivers Schottky-equivalent VF without control circuitry, though peak efficiency is ~1–2% lower than optimized synchronous designs at light loads.
