Product details
Overview
MBRF7100 from Taiwan Semiconductor is a 7.5A, 100V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (0.92 V at 7.5 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 industrial SMPS.
For engineers reviewing the MBRF7100 datasheet, MBRF7100 pinout, MBRF7100 application, or MBRF7100 equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 0.92 V forward drop at rated current, 7°C/W junction-to-case thermal resistance, and ITO-220AC mounting compatibility with standard heatsinks.
Technical Context
The MBRF7100 employs a single-die Schottky structure optimized for low conduction loss and fast switching in continuous conduction mode (CCM) power supplies. Its 100 V VRRM, 150 A IFSM, and 150°C maximum junction temperature support robust operation under transient overloads and elevated ambient conditions.
Guard ring design enhances ruggedness against voltage transients, while matte tin-plated leads ensure reliable solderability per J-STD-002. The device meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V–72 V output DC/DC stages |
| IF | 7.5 A - Continuous average forward current; supports ≥60 W output at 85% efficiency in compact adapters |
| VF | 0.92 V @ 7.5 A, 25°C - Low conduction loss reduces thermal stress and improves system efficiency vs. silicon diodes |
| IFSM | 150 A - Non-repetitive surge rating; withstands inrush and fault currents without failure |
| RθJC | 7°C/W - Enables direct heatsink mounting for thermal management in space-constrained industrial enclosures |
| TJ max | 150°C - Allows operation in high-ambient environments such as enclosed power modules or automotive under-hood locations |
Pinout & Package
Package: ITO-220AC - Insulated TO-220 variant with electrically isolated tab, UL 94V-0 molding compound, and matte tin-plated leads for reflow and wave soldering.

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-75SQ040 | 40 V VRRM, 75 A IF, TO-263 package - lower voltage rating, higher current, surface-mount | Not suitable for 100 V bus designs; better for low-VOUT high-current applications like GPU VRMs | Select only if system VRRM requirement ≤40 V and SMT assembly is mandatory |
| ON Semiconductor MBR7100CT | Dual common-cathode configuration, TO-220AB package - same VRRM/IF, but dual-diode topology and non-isolated tab | Requires insulating hardware for heatsink mounting; suited for dual-output or redundant rectification | Choose when dual-diode functionality or cost-sensitive dual-channel design is needed |
Compared with MBRF7100, VS-75SQ040 offers higher current but insufficient voltage margin for 100 V systems, while MBR7100CT provides dual-diode integration at the cost of electrical isolation - making MBRF7100 optimal for isolated, single-channel, high-ruggedness 100 V rectification.

FAQ
What is the maximum junction temperature rating for MBRF7100?
The MBRF7100 has a maximum junction temperature (TJ) of 150°C, enabling operation in high-ambient environments such as enclosed power modules or under-hood automotive applications. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2105). Thermal design must maintain junction temperature below this limit using the specified 7°C/W junction-to-case resistance and appropriate heatsinking.
Is MBRF7100 available in an AEC-Q101 qualified version?
Yes, the MBRF7100H variant is AEC-Q101 qualified and marked with "H" in the ordering code. It undergoes extended stress testing including temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 standards. The base MBRF7100 is not qualified; only MBRF7100H carries this certification, and both share identical electrical and thermal specifications.
What is the forward voltage of MBRF7100 at 7.5 A and 125°C?
The forward voltage of MBRF7100 is 0.82 V at 7.5 A and 125°C, as specified in the Electrical Specifications table (Version K2105). This value reflects reduced voltage drop at elevated temperature due to Schottky physics, supporting stable performance across wide thermal ranges in industrial power supplies.
Does MBRF7100 have a guard ring structure?
Yes, MBRF7100 incorporates a guard ring for over-voltage protection, explicitly listed under FEATURES in the Taiwan Semiconductor datasheet. This structure improves edge termination robustness, enhancing resistance to voltage transients and localized avalanche during switching events in SMPS and DC/DC converter applications.
What packaging and taping options are available for MBRF7100?
MBRF7100 is supplied in ITO-220AC package, packed 50 units per tube. No tape-and-reel or bulk options are specified in the official Ordering Information section (Version K2105). The "H" suffix (e.g., MBRF7100H) denotes AEC-Q101 qualification but does not change packaging - both versions use identical tube packing.
