Product details
Overview
MBRF750 from Taiwan Semiconductor is a 7.5A, 50V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (0.75V at 7.5A, 25°C), 150A surge capability, and AEC-Q101 qualification option. It serves as a high-efficiency output rectifier in DC/DC converters and switching power supplies where thermal robustness and low conduction loss are critical.
For engineers reviewing the MBRF750 datasheet, MBRF750 pinout, MBRF750 application, or MBRF750 equivalent, key selection factors include its 50V VRRM, 7°C/W junction-to-case thermal resistance, 10mA reverse leakage at 125°C, and compatibility with surface-mount heatsink mounting via ITO-220AC's isolated tab.
Technical Context
The MBRF750 operates as a single-die, unidirectional Schottky rectifier optimized for high-frequency switching topologies. Its 50V repetitive peak reverse voltage and 150A non-repetitive surge rating support transient-heavy industrial and automotive power rails.
Thermal performance is defined by a 7°C/W junction-to-case resistance and 150°C maximum junction temperature, enabling stable operation under sustained 7.5A DC load when properly heatsinked. The device uses matte tin-plated leads compliant with J-STD-002 solderability standards.

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-75CTQ050 | Same 50V VRRM, 75A dual common-cathode configuration; higher IF per die (37.5A), larger TO-247AC package | Requires PCB layout change; suited for parallel-output or dual-rail systems, not direct replacement | Select when higher current sharing or dual-channel integration is needed; not pin-compatible |
| ON Semiconductor MBR750 | Identical 50V/7.5A rating and ITO-220AC package; VF = 0.72V (typ) at 7.5A, 25°C - slightly lower conduction loss | No functional or mechanical differences; qualifies for same applications with identical mounting | Drop-in alternative with marginally improved efficiency; verify marking and AEC-Q101 availability per batch |
Compared with VS-75CTQ050 and MBR750, the MBRF750 offers standardized ITO-220AC footprint and AEC-Q101 option, while MBR750 provides minor VF advantage and VS-75CTQ050 enables higher current scalability at the cost of layout redesign.

FAQ
What is the maximum junction temperature rating for MBRF750?
The MBRF750 has a maximum junction temperature (TJ) of 150°C, as specified in its absolute maximum ratings. This rating allows operation in high-ambient environments when thermal design accounts for its 7°C/W junction-to-case resistance and proper heatsinking. Derating curves in the MBRF750 datasheet define safe current limits above 25°C ambient.
Does MBRF750 have AEC-Q101 qualification?
The MBRF750 is available in an AEC-Q101 qualified version denoted by the "H" suffix (e.g., MBRF750H). Standard MBRF750 is not automatically qualified; qualification applies only to parts ordered with the H suffix and confirmed in TSC's official AEC-Q101 certificate listing. Always verify the ordering code and packaging label.
What is the forward voltage of MBRF750 at 7.5A and 125°C?
The MBRF750 exhibits a typical forward voltage of 0.65V at 7.5A and 125°C junction temperature, per its electrical specifications table. This value reflects reduced voltage drop at elevated temperature due to Schottky physics and supports stable performance in thermally stressed applications like under-hood automotive converters.
Can MBRF750 be used in place of MBRF745 or MBRF760?
The MBRF750 is not interchangeable with MBRF745 (45V) or MBRF760 (60V) without circuit review. While all share identical package, current rating, and thermal specs, their VRRM differs - using MBRF750 in a 60V design risks reverse breakdown, and using MBRF760 in a 50V design adds unnecessary cost and capacitance. Voltage rating must match system requirements.
What does the "ITO" in ITO-220AC signify for MBRF750?
"ITO" in ITO-220AC stands for "Insulated TO-220AC", indicating the metal tab is electrically isolated from the internal die and leads. For MBRF750, this allows direct mounting to a grounded heatsink without shorting the cathode, simplifying thermal management in high-voltage isolation schemes while maintaining creepage/clearance compliance.
