Product details
Overview
MBRF1050CTH from Taiwan Semiconductor is a 10A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 50V repetitive peak reverse voltage (VRRM), 120A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.80V max at 10A, 25°C) and low reverse leakage (10mA max at 125°C), enabling high-efficiency operation in DC-DC converters and automotive-grade power supplies.
For engineers reviewing the MBRF1050CTH datasheet, MBRF1050CTH pinout, MBRF1050CTH application, or MBRF1050CTH equivalent, key selection criteria include its AEC-Q101 qualification, 3.5°C/W junction-to-case thermal resistance, dual common-cathode configuration, and compatibility with high-frequency switching topologies requiring fast recovery and minimal conduction loss.
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its guard ring structure provides overvoltage protection, while matte tin-plated leads ensure reliable solderability per J-STD-002.
The MBRF1050CTH operates across -55°C to +150°C junction temperature range and supports critical dv/dt of 10,000 V/µs. Its low VF and low IR characteristics are specified at both 25°C and 125°C, confirming stable performance under thermal stress in compact power designs.

FAQ
What is the pin configuration of the MBRF1050CTH?
The MBRF1050CTH uses a three-terminal ITO-220AB package with Tab = Anode 1, Lead 1 = Anode 2, and Lead 2 = Common Cathode. This dual-anode/common-cathode arrangement supports OR-ing, interleaved outputs, or independent channel rectification. Mounting torque must not exceed 0.56 N·m to avoid mechanical damage to the internal bond wires.
Is the MBRF1050CTH qualified for automotive applications?
Yes, the "H" suffix in MBRF1050CTH explicitly denotes AEC-Q101 qualification. The device has passed stress tests including HTOL, temperature cycling, and unbiased HAST, making it suitable for under-hood and cabin applications such as engine control units, ADAS power supplies, and infotainment DC-DC converters.
What is the maximum junction temperature rating for the MBRF1050CTH?
The MBRF1050CTH has a maximum junction temperature (TJ MAX) of +150°C, verified across its full operating range from -55°C to +150°C. This rating is supported by its 3.5°C/W junction-to-case thermal resistance and UL 94V-0 flammability-rated molding compound, enabling reliable operation in thermally demanding environments.
How does the forward voltage of the MBRF1050CTH compare at elevated temperatures?
At 10A and 125°C, the MBRF1050CTH exhibits a maximum forward voltage of 0.75V-significantly lower than standard silicon rectifiers. This low VF drift with temperature ensures consistent conduction loss and efficiency retention in automotive and industrial applications where ambient temperatures routinely exceed 85°C.
What packaging and ordering options are available for the MBRF1050CTH?
The MBRF1050CTH is supplied in tubes of 50 units per tube, packaged in the ITO-220AB outline. Ordering code MBRF1050CTH explicitly identifies the AEC-Q101 qualified version; non-H variants (e.g., MBRF1050CT) lack automotive qualification and differ in traceability and test documentation.
