Product details
Overview
MBRF1035 from Taiwan Semiconductor is a 10A, 35V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (0.70 V at 10 A, 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 and switching power supplies for industrial and automotive auxiliary rails.
For engineers reviewing the MBRF1035 datasheet, MBRF1035 pinout, MBRF1035 application, or MBRF1035 equivalent, key selection criteria include its 35 V repetitive peak reverse voltage, 150 A non-repetitive surge rating, junction-to-case thermal resistance of 3 °C/W, and compatibility with lead-free reflow per J-STD-002.
Technical Context
The MBRF1035 uses a single-die Schottky structure optimized for low conduction loss in medium-voltage SMPS outputs. Its guard ring design enhances over-voltage ruggedness, while the matte tin-plated leads ensure reliable solderability and whisker resistance per JESD201 Class 2.
Operating from –55°C to +150°C junction temperature, it delivers stable forward voltage down to 0.57 V at 10 A and 125°C, enabling thermally constrained designs. Reverse leakage remains ≤100 µA at 25°C and ≤15 mA at 125°C under rated 35 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 10 A continuous - supports high-current secondary-side rectification without forced air cooling |
| Repetitive Peak Reverse Voltage (VRRM) | 35 V - suitable for 24 V nominal input/output DC/DC stages and 3.3–12 V system rails |
| Surge Peak Forward Current (IFSM) | 150 A (8.3 ms half-sine) - withstands startup inrush and transient overload events |
| Forward Voltage (VF) | 0.70 V max at 10 A, 25°C - reduces conduction loss vs. standard PN diodes, improving efficiency by ~1–2% |
| Junction-to-Case Thermal Resistance (RθJC) | 3 °C/W - enables direct heatsink mounting for thermal management in compact power modules |
| Reverse Leakage Current (IR) | 100 µA max at 35 V, 25°C - ensures minimal standby power loss in always-on circuits |

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-10BQ030 | Same 10 A / 35 V rating; VF = 0.52 V typ at 10 A, 25°C; TO-220AC package; no AEC-Q101 option | Lower VF improves light-load efficiency but lacks automotive qualification | Select for cost-sensitive industrial adapters where AEC-Q101 is not required |
| ON Semiconductor MBR1035CT | Dual common-cathode configuration (2×5 A); VF = 0.72 V max; TO-220AB package; tab not electrically isolated | Requires dual-output or parallel-path designs; tab tied to cathode limits heatsink isolation | Choose when dual-output rectification or shared cathode routing is needed, accepting non-isolated tab |
Compared with VS-10BQ030 and MBR1035CT, the MBRF1035 offers electrically isolated tab mounting and optional AEC-Q101 qualification-critical for automotive and safety-certified industrial systems-while maintaining competitive VF and surge robustness.

FAQ
What is the maximum junction temperature rating for the MBRF1035?
The MBRF1035 has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows use in high-ambient environments such as enclosed power supplies or under-hood automotive locations when properly heatsinked. The 3 °C/W junction-to-case thermal resistance supports effective heat transfer to external heatsinks.
Does the MBRF1035 have an AEC-Q101 qualified version?
Yes, the MBRF1035H is the AEC-Q101 qualified variant of the MBRF1035, explicitly listed in the ordering information. It undergoes additional stress testing for automotive applications, including temperature cycling, humidity bias, and mechanical shock. Standard MBRF1035 is not AEC-Q101 qualified unless ordered with the "H" suffix.
What is the reverse leakage current of the MBRF1035 at elevated temperature?
At 35 V reverse bias and 125°C junction temperature, the MBRF1035 exhibits a maximum reverse leakage current (IR) of 15 mA. At 25°C, IR is limited to 100 µA. This behavior is confirmed in the Electrical Specifications table and impacts standby power loss in always-on systems.
How does the ITO-220AC package differ from standard TO-220AC?
The ITO-220AC package used by the MBRF1035 features an electrically isolated metal tab, unlike standard TO-220AC where the tab is internally connected to the cathode. This isolation allows direct heatsink mounting without insulating hardware, simplifying thermal design and improving reliability in high-voltage isolation applications.
What is the forward voltage drop of the MBRF1035 at 10 A and 125°C?
The MBRF1035 has a typical forward voltage drop of 0.57 V at 10 A and 125°C junction temperature, as specified in the Electrical Specifications table. This lower VF at elevated temperature reflects the positive temperature coefficient of Schottky diodes and supports stable performance in thermally stressed power stages.
