Product details
Overview
MBRF2050 from Taiwan Semiconductor is a 20A, 50V Schottky barrier rectifier in ITO-220AC package, designed for high-efficiency DC–DC conversion and switching power supplies. It delivers low forward voltage (0.82 V at 20 A, 25°C), 150 A surge capability, and operates up to 150°C junction temperature.
For engineers reviewing the MBRF2050 datasheet, MBRF2050 pinout, MBRF2050 application, or MBRF2050 equivalent, this device is selected for high-current, low-loss rectification where thermal performance (RθJC = 3°C/W), AEC-Q101 qualification readiness, and robust surge handling are critical.
Technical Context
The MBRF2050 uses a single-die Schottky structure optimized for fast recovery and minimal conduction loss. Its 50 V repetitive peak reverse voltage (VRRM) and 10 mA reverse leakage at 125°C support stable operation in mid-voltage SMPS rails.
Thermally, it features a low 3°C/W junction-to-case resistance and UL 94V-0 molding compound, enabling direct heatsink mounting with ≤0.56 N·m torque. Guard ring protection enhances overvoltage ruggedness without compromising switching speed.
Key Specifications

|---|---|
| VRRM | 50 V - Maximum blocking voltage in repetitive reverse bias; defines usable input/output rail range |
| IF | 20 A - Continuous average forward current; sets minimum heatsink sizing for steady-state loads |
| VF @ 20 A, 25°C | 0.82 V - Low conduction loss directly reduces power dissipation and improves system efficiency |
| IFSM | 150 A - Peak non-repetitive surge rating; supports inrush and transient overload tolerance |
| RθJC | 3 °C/W - Thermal resistance from junction to case; enables precise heatsink thermal design |
| TJ max | 150 °C - Maximum operating junction temperature; allows high-ambient deployment in enclosed systems |
| IR @ 50 V, 125°C | 10 mA - Reverse leakage at elevated temperature; impacts standby power and thermal runaway margin |
Pinout & Package
Package: ITO-220AC - Insulated TO-220 variant with isolated tab, matte tin-plated leads, UL 94V-0 molding, and polarity marking per device top-side marking.
| Pin/Terminal | Circuit Role | Design Meaning |

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-20BQ050 | Same 50 V VRRM, 20 A IF, but TO-220AC (non-isolated tab); RθJC = 3.5°C/W | Requires electrical isolation hardware (mica washer + shoulder washer) for heatsink mounting | Choose when cost sensitivity outweighs assembly complexity and thermal margin is acceptable |
| ON Semiconductor MBR2050CT | Dual common-cathode configuration (2×10 A), TO-220AB package; not single-die ITO-220AC | Not pin-compatible; requires PCB redesign and dual-output layout | Consider only if dual-output topology or paralleled current sharing is required |
Compared with VS-20BQ050 and MBR2050CT, the MBRF2050 offers electrically isolated mounting in standard ITO-220AC, tighter thermal resistance, and direct drop-in compatibility in space-constrained, thermally demanding single-output designs.

FAQ
What is the maximum junction temperature rating for MBRF2050?
The MBRF2050 has a maximum junction temperature (TJ) of 150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules. Derating curves confirm usable current capacity down to 125°C case temperature, and the MBRF2050 must be mounted to a heatsink capable of maintaining TJ ≤ 150°C under worst-case load and ambient conditions.
Is MBRF2050 AEC-Q101 qualified?
The base MBRF2050 is not AEC-Q101 qualified; however, the variant MBRF2050H is explicitly rated to AEC-Q101. The datasheet confirms AEC-Q101 qualification applies only to parts marked with the "H" suffix. For automotive applications requiring qualification evidence, MBRF2050H must be specified-standard MBRF2050 meets all electrical and thermal specs but lacks formal stress-test documentation per AEC-Q101.
What does the "F" in MBRF2050 signify?
The "F" in MBRF2050 denotes Taiwan Semiconductor's internal product family identifier for ITO-220AC packaged Schottky rectifiers. It distinguishes this series from TO-220AB (MBR20xx) or D2PAK (MBR20xxCT) variants. The "F" does not indicate function, frequency, or feature-it is a package-specific prefix used consistently across MBRF2035 through MBRF20100 to identify the insulated TO-220 outline.
How does MBRF2050 compare to MBRF2060 in forward voltage?
At 20 A and 25°C, the MBRF2050 has a maximum forward voltage (VF) of 0.82 V, while the MBRF2060 is rated at the same 0.82 V maximum. Both share identical VF specs under those conditions, but the MBRF2060 supports higher blocking voltage (60 V vs. 50 V). Designers selecting between them prioritize voltage margin over VF difference-no practical VF trade-off exists at rated current.
What is the reverse leakage current of MBRF2050 at 125°C?
The MBRF2050 exhibits a maximum reverse leakage current (IR) of 10 mA at rated 50 V reverse voltage and 125°C junction temperature, per the Electrical Specifications table. This value is confirmed in the datasheet's "Reverse current @ rated VR" row for MBRF2050/MBRF2060 at TJ = 125°C. It reflects thermal stability under sustained high-temperature operation and impacts standby power budget in always-on systems.
