Product details
Overview
MBRF1090CTH from Taiwan Semiconductor is a 10A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 90V repetitive peak reverse voltage (VRRM), 120A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.95V max at 10A/25°C) and exhibits only 5mA reverse leakage at 125°C, making it suitable for high-efficiency DC-DC converters in automotive power systems.
For engineers reviewing the MBRF1090CTH datasheet, MBRF1090CTH pinout, MBRF1090CTH application, or MBRF1090CTH equivalent, key selection criteria include its AEC-Q101 qualification, 3.5°C/W junction-to-case thermal resistance, guard ring overvoltage protection, and compatibility with high-surge, low-loss switching power topologies requiring stable unidirectional conduction.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent die in a single ITO-220AB thermally enhanced package, enabling synchronous or interleaved output configurations. Its design targets high-frequency switching applications where low VF and fast recovery eliminate minority-carrier storage delay.
The device features a guard ring structure to suppress edge breakdown under transient overvoltage, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Matte tin-plated leads ensure reliable solderability per J-STD-002.

FAQ
What is the maximum junction temperature rating for MBRF1090CTH?
The MBRF1090CTH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating enables operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm sustained 10A conduction is possible up to 75°C case temperature. The MBRF1090CTH must be mounted to an appropriate heatsink to maintain TJ ≤ 150°C under full load.
Is MBRF1090CTH pin-compatible with non-AEC-Q101 versions like MBRF1090CT?
Yes, MBRF1090CTH shares identical ITO-220AB package dimensions, pinout, and thermal pad configuration with MBRF1090CT. The "H" suffix denotes AEC-Q101 qualification only-the silicon die, electrical characteristics, and mechanical interface are unchanged. The MBRF1090CTH can replace MBRF1090CT on existing PCBs without layout modification, provided automotive qualification is required.
What is the forward voltage drop of MBRF1090CTH at 10A and 125°C?
The MBRF1090CTH exhibits a maximum forward voltage drop of 0.85V at 10A and 125°C, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value reflects real-world performance under elevated temperature conditions typical in enclosed power supplies. At room temperature, VF is 0.95V max at 10A. The MBRF1090CTH's low VF across temperature improves system efficiency and reduces thermal stress on downstream components.
Does MBRF1090CTH include guard ring protection?
Yes, MBRF1090CTH incorporates a guard ring structure explicitly stated in the Features section of the Taiwan Semiconductor datasheet to enhance overvoltage ruggedness. This design mitigates edge breakdown under high dv/dt stress, supporting reliable operation at up to 10,000 V/µs. The guard ring is integral to the die fabrication process and contributes to the MBRF1090CTH's ability to withstand transient surges in automotive and industrial power systems.
What packaging and plating specifications apply to MBRF1090CTH?
MBRF1090CTH uses ITO-220AB packaging with matte tin-plated leads compliant with J-STD-002 solderability standards. Each tube contains 50 units. The molding compound meets UL 94V-0 flammability rating, and the device passes JESD201 Class 2 whisker testing. Polarity is marked on the body, and mounting torque must not exceed 0.56 N·m. These specifications ensure MBRF1090CTH's suitability for automated assembly and long-term field reliability.
