Product details
Overview
MBRF2080CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 20A average forward current, 80V repetitive peak reverse voltage (VRRM), and 150A non-repetitive surge current (IFSM). It delivers low forward voltage drop of 1.00 V at 10 A and 25°C, enabling high-efficiency operation in DC–DC converters and switching power supplies.
For engineers reviewing the MBRF2080CT datasheet, MBRF2080CT pinout, MBRF2080CT application, or MBRF2080CT equivalent, key selection criteria include its 80 V VRRM, 3.5 °C/W junction-to-case thermal resistance, 30 mA reverse leakage at 125°C, dual common-cathode configuration, and AEC-Q101 qualification option (MBRF2080CTH).
Technical Context
The MBRF2080CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its guard ring structure provides overvoltage protection, while matte tin-plated leads ensure reliable solderability per J-STD-002.
Designed for high-frequency switching applications, it supports 10,000 V/µs critical rate of rise of off-state voltage (dv/dt) and operates across –55°C to +150°C junction temperature range. Thermal performance is characterized by RθJC = 3.5 °C/W for the 80–200 V variants.
Key Specifications

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-20BQ080PbF | Same 80 V VRRM, 20 A IF, but TO-220AC package (single anode); RθJC = 3.0 °C/W; VF = 0.82 V @ 10 A, 25°C. | Not dual-common-cathode; requires separate cathode routing; better thermal resistance but lacks integrated dual topology. | Select when single-diode layout suffices and lower VF outweighs dual-diode integration needs. |
| ON Semiconductor MBR2080CT | Identical electrical specs and ITO-220AB package; same pinout and marking; RoHS-compliant but not AEC-Q101 qualified in standard version. | Functionally identical for industrial use; AEC-Q101 option only available via Taiwan Semiconductor's MBRF2080CTH variant. | Choose MBRF2080CT for automotive-grade traceability and qualification assurance; otherwise MBR2080CT offers cross-supply redundancy. |
Compared with VS-20BQ080PbF and MBR2080CT, the MBRF2080CT uniquely combines dual-common-cathode integration, AEC-Q101 availability, and 3.5 °C/W thermal resistance in ITO-220AB-making it optimal for space- and reliability-constrained dual-rail power systems.

FAQ
What is the maximum junction temperature rating for the MBRF2080CT?
The MBRF2080CT has a maximum junction temperature (TJ) rating of +150°C, with a full operational range from –55°C to +150°C. This rating is validated under specified thermal conditions and supports use in under-hood automotive environments and high-ambient industrial settings. Derating curves in the official datasheet define allowable forward current versus case temperature, and the MBRF2080CT must be mounted to an appropriate heatsink to maintain TJ ≤ 150°C during continuous operation.
Is the MBRF2080CT pin-compatible with other parts in the MBRF20xxCT family?
Yes, all MBRF20xxCT variants-including MBRF2035CT through MBRF20200CT-share identical ITO-220AB packaging, pinout, and mechanical footprint. The MBRF2080CT uses the same three-terminal configuration (common cathode tab, Anode 1, Anode 2), enabling direct board-level substitution within the same voltage class when thermal and electrical margins permit. However, forward voltage and leakage characteristics differ across voltage grades, so electrical validation is required before replacement.
Does the MBRF2080CT have AEC-Q101 qualification?
The standard MBRF2080CT is not AEC-Q101 qualified, but the MBRF2080CTH variant-identical in all electrical and mechanical specifications-is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening, including stress testing for temperature cycling, humidity bias, and mechanical shock. For automotive applications requiring formal qualification, specify MBRF2080CTH; the MBRF2080CT remains suitable for industrial and commercial designs where AEC-Q101 is not mandated.
What is the forward voltage drop of the MBRF2080CT at elevated temperature?
At 10 A forward current and 125°C junction temperature, the MBRF2080CT exhibits a maximum forward voltage drop (VF) of 0.75 V per diode. This represents a significant reduction from its 1.00 V rating at 25°C, reflecting the negative temperature coefficient typical of Schottky diodes. Designers should use this value for worst-case thermal analysis in high-ambient applications such as enclosed power supplies or automotive junction boxes.
How is thermal performance characterized for the MBRF2080CT?
The MBRF2080CT has a junction-to-case thermal resistance (RθJC) of 3.5 °C/W, measured under standardized test conditions with the tab fully contacting a cold plate. This value applies to the 80–200 V subfamily and enables accurate heatsink sizing using θJA models or finite-element simulation. Mounting torque must not exceed 0.56 N·m to avoid package damage, and matte tin-plated leads ensure consistent solder joint integrity for long-term thermal interface reliability.
