Product details
Overview
MBRF20100H from Taiwan Semiconductor is a 20A, 100V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.95V max forward voltage at 20A/25°C, 150A surge capability, and guard ring over-voltage protection-used in automotive-grade DC-DC converters and high-efficiency SMPS.
For engineers reviewing the MBRF20100H datasheet, MBRF20100H pinout, MBRF20100H application, or MBRF20100H equivalent, key selection criteria include its 100V VRRM rating, AEC-Q101 qualification, thermal resistance of 3°C/W (junction-to-case), low reverse leakage (100µA @ 25°C), and compatibility with high-reliability power conversion designs requiring UL recognition and halogen-free compliance.
Technical Context
This single-die Schottky rectifier operates with a maximum junction temperature of 150°C and supports repetitive peak reverse voltages up to 100V. Its 3°C/W thermal resistance enables efficient heat transfer to heatsinks in high-current applications.
The device delivers 40A peak repetitive forward current under square-wave conditions (20kHz) and sustains 150A non-repetitive surge current (8.3ms half-sine), making it suitable for transient-heavy power rails where low forward loss and fast recovery are critical.

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-20CPH10-M3 | Same ITO-220AC package, 20A/100V, VF = 0.87V (typ) @ 20A, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial SMPS only | Select when AEC-Q101 is not required and lower typical VF is prioritized |
| ON Semiconductor MBR20100CT | TO-220AB dual-common-cathode configuration, 2 × 10A rating, VF = 0.92V (max), no AEC-Q101 | Dual-diode layout enables center-tapped transformer designs; not pin-compatible | Choose for dual-output or interleaved topologies where single-diode MBRF20100H does not fit |
Compared with VS-20CPH10-M3 and MBR20100CT, the MBRF20100H uniquely combines AEC-Q101 qualification, single-diode ITO-220AC form factor, and guaranteed 100V VRRM-making it the only option for automotive-grade single-channel rectification where qualification and mechanical fit are mandatory.

FAQ
What is the maximum junction temperature rating for MBRF20100H?
The MBRF20100H has a maximum junction temperature (TJ max) of 150°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Thermal design must maintain junction temperature below this limit using the specified 3°C/W RθJC and appropriate heatsinking. The MBRF20100H datasheet provides derating curves for continuous current versus case temperature.
Is MBRF20100H pin-compatible with standard ITO-220AC rectifiers?
Yes, the MBRF20100H uses the industry-standard ITO-220AC outline with Anode–Cathode–Tab pin assignment and 0.56 N·m maximum mounting torque. It shares identical mechanical dimensions and lead pitch with other ITO-220AC devices such as MBRF2060H and VS-20CPH10-M3, enabling drop-in replacement in existing layouts-provided thermal and electrical requirements are verified.
Does MBRF20100H meet UL safety standards?
Yes, the MBRF20100H is UL Recognized under File #E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for use in end equipment requiring safety certification. The ITO-220AC package uses UL 94V-0 rated molding compound, and all materials meet halogen-free requirements per IEC 61249-2-21. This applies specifically to the MBRF20100H variant, not the non-H suffix versions.
What is the forward voltage specification for MBRF20100H at elevated temperature?
At 20A and 125°C junction temperature, the MBRF20100H exhibits a maximum forward voltage (VF) of 0.87V-lower than its 25°C rating of 0.95V. This negative temperature coefficient is characteristic of Schottky diodes and improves thermal stability in high-power applications. The MBRF20100H datasheet specifies this value under pulse test conditions (PW = 0.3ms) and confirms performance across the full -55°C to +150°C operating range.
How does the guard ring feature benefit MBRF20100H in real-world circuits?
The guard ring in the MBRF20100H enhances edge termination robustness, increasing resistance to avalanche breakdown during voltage transients. It directly supports the device's 10,000 V/µs critical rate of rise of off-state voltage (dv/dt), preventing false turn-on in fast-switching converters. In automotive load-dump scenarios or industrial motor drive regeneration, this feature maintains blocking integrity where conventional Schottky diodes may fail prematurely-verified in AEC-Q101 stress testing of the MBRF20100H.
