Product details
Overview
MBRF3090CTH from Taiwan Semiconductor is a 30A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 90V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.94V at 30A/25°C) and supports high-efficiency switching mode power supplies, DC-DC converters, and automotive-grade adapters.
For engineers reviewing the MBRF3090CTH datasheet, MBRF3090CTH pinout, MBRF3090CTH application, or MBRF3090CTH equivalent, key selection criteria include its AEC-Q101 qualification, 4°C/W junction-to-case thermal resistance, guard ring overvoltage protection, and compatibility with high-surge, low-loss power conversion designs requiring stable 90V blocking capability.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent die in a single ITO-220AB thermally enhanced package, enabling synchronous or parallel rectification paths without external isolation. Its 10,000 V/µs critical dv/dt rating ensures robustness against fast-switching transients in high-frequency SMPS topologies.
The device operates across –55°C to +150°C junction range, with reverse leakage limited to 10 mA per diode at 125°C and rated VR - a critical parameter for thermal stability in compact, convection-cooled adapter designs where IR-driven self-heating must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback/freewheeling applications |
| IF | 30 A - Continuous average forward current per diode; determines steady-state power handling in DC-DC output stages |
| IFSM | 200 A - Non-repetitive surge current (8.3 ms half-sine); enables reliable startup and fault tolerance in high-inrush systems |
| VF @ 30A/25°C | 0.94 V - Forward voltage per diode; directly impacts conduction loss and thermal design margin at full load |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; allows accurate heatsink sizing for 30A operation under 150°C max TJ |
| IR @ 90V/125°C | 10 mA - Reverse leakage per diode; constrains standby power loss and thermal runaway risk in high-temp environments |
| TJ max | 150 °C - Maximum allowable junction temperature; sets upper boundary for derating curves and reliability modeling |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH09-M3 | Same ITO-220AB package, 90V VRRM, 30A IF, but higher VF (0.97V @ 30A/25°C) and no AEC-Q101 qualification | Suitable for industrial/commercial SMPS where automotive qualification is not required | Select MBRF3090CTH when AEC-Q101 compliance and lower conduction loss are mandatory |
| ON Semiconductor MBR3090CT | Identical electrical specs and package, but lacks AEC-Q101 qualification and halogen-free certification | Acceptable for cost-sensitive consumer adapters with less stringent reliability requirements | Choose MBRF3090CTH for automotive, medical, or long-lifecycle deployments requiring traceable qualification |

FAQ
What is the maximum junction temperature rating for MBRF3090CTH?
The MBRF3090CTH has a maximum junction temperature (TJ max) of +150°C, validated across its full operating range from –55°C to +150°C. This rating enables use in high-ambient environments such as engine compartments or enclosed power supplies, provided thermal design accounts for its 4°C/W junction-to-case resistance and actual power dissipation derived from VF and IF.
Is MBRF3090CTH pin-compatible with MBRF3090CT?
Yes, MBRF3090CTH shares identical ITO-220AB mechanical dimensions, pinout, and terminal configuration with MBRF3090CT. The "H" suffix denotes AEC-Q101 qualification and halogen-free construction, but does not alter physical layout or electrical pin functions - both parts mount identically and require no PCB changes.
What is the forward voltage of MBRF3090CTH at 30A and 125°C?
The MBRF3090CTH exhibits a maximum forward voltage (VF) of 0.82 V per diode at 30A and 125°C, as specified in the Electrical Specifications table. This value reflects real-world thermal performance under elevated temperature conditions and is critical for calculating conduction losses and thermal management in high-load, high-ambient applications.
Does MBRF3090CTH include overvoltage protection features?
Yes, MBRF3090CTH incorporates a guard ring structure explicitly designed to enhance edge termination robustness and suppress premature avalanche breakdown during voltage transients. This built-in feature improves reliability in fast-switching circuits without requiring external snubbers or clamping components.
