Taiwan Semiconductor Corporation MBRF1090HC0G

Overview

MBRF1090HC0G from Taiwan Semiconductor is a 10A, 90V dual-die Schottky barrier rectifier in ITO-220AB package, featuring low forward voltage (0.95V @ 10A, 25°C), high surge current capability (120A), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-efficiency DC/DC converters and industrial SMPS.

For engineers reviewing the MBRF1090HC0G datasheet, MBRF1090HC0G pinout, MBRF1090HC0G application, or MBRF1090HC0G equivalent, key selection criteria include its 90V V_RRM, 3.5°C/W junction-to-case thermal resistance, dual common-cathode configuration, and halogen-free, RoHS-compliant construction per IEC 61249-2-21.

Technical Context

This device integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package with common cathode connection, enabling synchronous rectification or dual-output configurations. Its guard ring structure provides overvoltage protection, and it supports repetitive reverse voltages up to 90V with dv/dt rating of 10,000 V/µs.

Designed for high-frequency switching applications, the MBRF1090HC0G delivers low conduction loss (VF ≤ 0.95V at 10A/25°C) and maintains stable reverse leakage (<5 mA @ 125°C), making it suitable for compact, thermally constrained power stages where efficiency and thermal management are critical.

FAQ

What is the maximum junction temperature rating for the MBRF1090HC0G?

The MBRF1090HC0G has a maximum junction temperature (T_J) of +150°C, allowing operation in high-ambient environments such as automotive engine compartments or enclosed industrial enclosures. This rating is validated across its full current range and supports derating curves referenced in the official Taiwan Semiconductor datasheet revision M2105. Thermal design must account for R_θJC = 3.5°C/W and mounting torque limits to maintain reliability at this temperature.

Does the MBRF1090HC0G have AEC-Q101 qualification?

Yes, the MBRF1090HC0G is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in Taiwan Semiconductor's M2105 datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-making MBRF1090HC0G suitable for automotive powertrain and chassis applications where zero-failure reliability is required.

What does the "C0G" suffix mean in MBRF1090HC0G?

The "C0G" suffix in MBRF1090HC0G denotes green compound (halogen-free epoxy) and date code format per Taiwan Semiconductor's marking convention. "C" indicates halogen-free packaging compliant with IEC 61249-2-21, and "0G" represents manufacturing week/year (e.g., 0G = 2020, week 0). This distinguishes it from non-halogen-free variants and confirms environmental compliance for RoHS and WEEE-regulated markets.

Is the MBRF1090HC0G pin-compatible with standard ITO-220AB dual-diode rectifiers?

Yes, the MBRF1090HC0G uses the industry-standard ITO-220AB outline with identical pin assignment (Anode1–Cathode–Anode2) and mechanical dimensions as other dual-common-cathode Schottky rectifiers in the same package. Mounting hole spacing, tab isolation, and lead pitch match JEDEC TO-220AB specifications, enabling direct replacement in existing layouts without PCB modification.

What is the typical forward voltage of the MBRF1090HC0G at 10A and 125°C?

The typical forward voltage (V_F) of the MBRF1090HC0G at 10A and 125°C is 0.85V, as specified in the Electrical Specifications table of the M2105 datasheet. This value reflects real-world performance under elevated thermal conditions and is critical for calculating conduction losses and thermal management in high-temperature applications such as under-hood automotive power supplies.
