Taiwan Semiconductor Corporation MBRF20H200CT

Overview

MBRF20H200CT from Taiwan Semiconductor is a 20A, 200V dual-die Schottky barrier rectifier in ITO-220AB package, featuring 0.97V max forward voltage at 20A/25°C, 150A surge capability, and AEC-Q101 qualification. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBRF20H200CT datasheet, MBRF20H200CT pinout, MBRF20H200CT application, or MBRF20H200CT equivalent, key selection criteria include repetitive peak reverse voltage (200V), junction-to-case thermal resistance (3.5°C/W), forward voltage at rated current, surge robustness (150A IFSM), and AEC-Q101 qualification status.

Technical Context

This dual-die Schottky rectifier integrates two independent 20A/200V diodes in a common-cathode configuration within a single ITO-220AB thermally enhanced package. Its guard ring structure provides overvoltage protection, and it supports operation up to 175°C junction temperature with 10,000 V/µs dv/dt rating.

The device delivers low conduction loss-0.97V max VF at 20A/25°C-and maintains 0.85V typical VF at 20A/125°C, enabling high-efficiency power conversion in thermally constrained environments. Reverse leakage remains ≤2 mA at 125°C and rated VR.

FAQ

What is the maximum junction temperature rating for MBRF20H200CT?

The MBRF20H200CT has a maximum junction temperature (TJ max) of +175°C, enabling reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. This rating is validated per JEDEC standards and supported by its 3.5°C/W junction-to-case thermal resistance. Thermal design must ensure case temperature stays within limits to avoid exceeding TJ max during sustained 20A conduction.

Is MBRF20H200CT pin-compatible with MBRF20H100CT or MBRF20H150CT?

Yes, MBRF20H200CT is mechanically and electrically pin-compatible with MBRF20H100CT and MBRF20H150CT-all share identical ITO-220AB package, common-cathode pinout, and marking layout. The only difference is VRRM rating (100V/150V/200V), so substitution requires verification that the higher voltage rating meets system blocking requirements without compromising efficiency or thermal behavior.

Does MBRF20H200CT require a heatsink in 20A continuous operation?

Yes, MBRF20H200CT requires a heatsink for 20A continuous operation. With 0.97V max VF at 20A/25°C, power dissipation exceeds 19W-exceeding the package's ability to self-cool. Using its RθJC of 3.5°C/W and assuming 25°C ambient, a heatsink with ≤1.5°C/W total thermal resistance (including interface) is needed to maintain TJ ≤125°C. Mounting torque must not exceed 0.56 N·m.

What does the "H" suffix in MBRF20H200CT signify?

The "H" suffix in MBRF20H200CT indicates AEC-Q101 qualification-confirming the device has passed stress tests for automotive power semiconductors, including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This distinguishes it from non-H variants like MBRF20200CT, which lack automotive qualification despite identical electrical specs.

Can MBRF20H200CT be used in place of a standard PN junction rectifier?

Yes, MBRF20H200CT can replace standard PN rectifiers in most 20A/200V applications, offering lower forward voltage (0.97V vs. ~1.1V), faster switching, and zero reverse recovery charge. However, its higher reverse leakage (up to 2 mA at 125°C) may require circuit-level validation in high-impedance bias networks or precision sensing paths where leakage could affect accuracy.
