Product details
Overview
MBRF7150 from Taiwan Semiconductor is a 7.5A, 150V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (1.02 V at 7.5A/25°C), high surge current capability (150 A), and AEC-Q101 qualification option. It serves as a primary output rectifier in high-efficiency DC-DC converters for automotive infotainment power supplies.
For engineers reviewing the MBRF7150 datasheet, MBRF7150 pinout, MBRF7150 application, or MBRF7150 equivalent, key selection criteria include its 150V reverse voltage rating, 0.92 V forward drop at 7.5A/125°C, junction-to-case thermal resistance of 7°C/W, and ITO-220AC mounting compatibility with standard heatsinks.
Technical Context
The MBRF7150 operates as a single-die, unidirectional Schottky rectifier optimized for high-frequency switching applications. Its 150V VRRM, 150A IFSM, and 10,000 V/µs dv/dt rating support robust operation in SMPS flyback and forward converter topologies under transient stress.
Thermally, it delivers 7°C/W junction-to-case resistance and supports continuous operation up to +150°C junction temperature. Reverse leakage remains ≤5 mA at 125°C and rated VR, enabling stable performance in thermally constrained automotive environments.
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-75SQ030 | 30V VRRM, 75A IF, TO-263 package - lower voltage, higher current, surface-mount | Not suitable for 150V blocking; requires PCB rework and thermal pad redesign | Select only for low-voltage, high-current SMT designs where footprint and assembly process differ |
| ON Semiconductor MBR7150 | Identical 150V VRRM, 7.5A IF, same ITO-220AC package, but not AEC-Q101 qualified | Acceptable for industrial/commercial use; lacks automotive qualification testing documentation | Choose MBRF7150 when AEC-Q101 compliance is required; otherwise MBR7150 offers cost parity |
Compared with VS-75SQ030 and MBR7150, the MBRF7150 uniquely combines 150V blocking, through-hole ITO-220AC mountability, and optional AEC-Q101 qualification-making it the only drop-in solution for automotive 12V/48V dual-rail DC-DC converters requiring both reliability and thermal serviceability.

FAQ
What is the maximum junction temperature rating for the MBRF7150?
The MBRF7150 has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature, with thermal design dependent on RθJC = 7°C/W and heatsink interface quality.
Is the MBRF7150 pin-compatible with other parts in the MBRF7xx family?
Yes, all MBRF7xx devices-including MBRF7150-share identical ITO-220AC packaging, pinout (anode/cathode/tab), and mechanical dimensions. Voltage ratings vary across the family (35V to 150V), but mounting, soldering, and thermal interface requirements remain consistent. No PCB layout change is needed when substituting within the series for voltage optimization.
Does the MBRF7150 have AEC-Q101 qualification?
The MBRF7150 is available in an AEC-Q101 qualified version denoted by the "H" suffix (e.g., MBRF7150H). Standard MBRF7150 units are not automatically qualified; qualification applies only to parts ordered with the H suffix and documented in TSC's AEC-Q101 certificate. Always verify ordering code and datasheet revision for qualification status before automotive deployment.
What is the forward voltage of the MBRF7150 at elevated temperature?
At 7.5A and 125°C junction temperature, the MBRF7150 exhibits a typical forward voltage (VF) of 0.92 V, per electrical specifications table. This represents a 0.10 V increase over its 25°C value (1.02 V), reflecting positive temperature coefficient behavior typical of Schottky diodes-critical for thermal stability analysis in high-power density designs.
How does the guard ring feature improve reliability in the MBRF7150?
The guard ring in the MBRF7150 enhances edge termination robustness by distributing electric field gradients away from the active junction periphery. This reduces localized avalanche breakdown risk during voltage transients, improves long-term reliability under repetitive overvoltage stress, and supports stable operation in noisy automotive power nets where load dump or inductive switching spikes occur.
