Product details
Overview
MBRF3090CT 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 is optimized for high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the MBRF3090CT datasheet, MBRF3090CT pinout, MBRF3090CT application, or MBRF3090CT equivalent, key selection criteria include its 90V VRRM rating, dual-common-cathode configuration, thermal resistance (RθJC = 4°C/W), AEC-Q101 qualification availability, and compatibility with high-surge, high-reliability industrial and automotive power systems.
Technical Context
The MBRF3090CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its guard ring structure provides overvoltage protection, and it supports 10,000 V/µs critical rate of rise of off-state voltage (dv/dt).
Designed for continuous conduction mode operation, it maintains low forward voltage (VF = 0.82V typ. at 30A, 125°C) and exhibits reverse leakage current ≤10 mA at 125°C and rated VR - enabling stable performance in high-temperature, high-frequency SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback or buck-derived topologies |
| IF | 30 A - Continuous average forward current per diode; enables compact heatsink design in 30–60W+ power stages |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients without failure |
| VF @ 30A, 25°C | 0.94 V max - Low conduction loss directly reduces power dissipation and improves system efficiency |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for effective thermal management |
| TJ max | 150 °C - Maximum allowable junction temperature; supports operation in sealed or high-ambient environments |
| IR @ 90V, 125°C | 10 mA max - Reverse leakage per diode at elevated temperature; limits standby power loss in high-temp applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH09 | Same ITO-220AB package, 30A/90V, VF = 0.87V max @ 30A, 25°C; no AEC-Q101 option listed | Targeted at industrial/commercial SMPS; lacks automotive qualification documentation | Select when AEC-Q101 is not required and lower VF is prioritized |
| ON Semiconductor MBR3090CT | Identical ratings (30A/90V), same dual-common-cathode ITO-220AB; VF = 0.95V max @ 30A, 25°C; RoHS-compliant but halogen-free status unspecified | Drop-in compatible in layout; used in telecom and computing power supplies | Select when supply chain diversification is needed and halogen-free compliance is non-mandatory |
Compared with MBRF3090CT, VS-30CPH09 offers slightly lower forward voltage but no automotive qualification, while MBR3090CT provides identical electrical specs and mechanical fit with different compliance emphasis - making MBRF3090CT preferable where halogen-free and AEC-Q101 readiness are design-critical.

FAQ
What is the maximum junction temperature rating for the MBRF3090CT?
The MBRF3090CT has a maximum junction temperature (TJ max) of +150°C, allowing reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. This rating is validated across its full current and voltage operating range and supports thermal design margins up to 85°C case temperature when mounted on an appropriate heatsink with ≤0.56 N·m torque.
Does the MBRF3090CT have AEC-Q101 qualification?
The MBRF3090CT is available in an AEC-Q101 qualified version denoted by the suffix "H" (e.g., MBRF3090CTH). The base MBRF3090CT part is not automatically qualified; qualification applies only to units ordered with the "H" suffix and documented in Taiwan Semiconductor's AEC-Q101 certificate reports. Always verify ordering code and packaging label for compliance status.
What is the forward voltage drop of the MBRF3090CT at full rated current?
At 30A and 25°C, the MBRF3090CT exhibits a maximum forward voltage drop (VF) of 0.94V per diode. At elevated temperature (125°C), VF is guaranteed ≤0.82V under the same conditions - confirming stable conduction performance across automotive and industrial thermal profiles.
How is the pin configuration arranged in the ITO-220AB package of the MBRF3090CT?
The MBRF3090CT uses a 3-pin ITO-220AB package with Pin 1 = Anode 1, Pin 2 = Common Cathode (electrically and thermally connected to the metal tab), and Pin 3 = Anode 2. This dual-anode, common-cathode arrangement supports center-tapped transformer rectification or dual-output DC/DC designs without external wiring between cathodes.
What is the thermal resistance from junction to case (RθJC) for the MBRF3090CT?
The MBRF3090CT has a typical junction-to-case thermal resistance (RθJC) of 4°C/W, measured from the silicon die to the metal tab surface. This value enables efficient heat transfer when the tab is mounted to a heatsink using thermal interface material and proper torque (≤0.56 N·m), supporting continuous 30A operation within safe thermal limits.
