Taiwan Semiconductor Corporation MBRS16100H

Overview

MBRS16100H from Taiwan Semiconductor is a 16A, 100V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for low forward voltage drop (0.85 V at 16 A, 25°C), high surge current capability (150 A), and automotive-grade reliability (AEC-Q101 qualified). It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.

For engineers reviewing the MBRS16100H datasheet, MBRS16100H pinout, MBRS16100H application, or MBRS16100H equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 1.5 °C/W junction-to-case thermal resistance, 300 µA reverse leakage at 25°C, and suitability for high-frequency, low-loss power conversion in automotive and industrial environments.

Technical Context

This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its thermal design supports continuous 16 A operation up to 150°C junction temperature, enabled by low R_θJC (1.5 °C/W) and UL 94V-0 molding compound.

The device operates with minimal conduction loss: VF remains ≤0.82 V at 16 A and 125°C, while reverse leakage stays ≤7.5 mA at rated VR and 125°C. It meets JESD201 Class 2 whisker resistance and moisture sensitivity level 1 per J-STD-020.

FAQ

What is the maximum junction temperature rating for MBRS16100H?

The MBRS16100H has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official datasheet. This allows reliable operation in under-hood automotive environments where ambient temperatures reach +105°C, provided thermal design maintains junction temperature below this limit. The device's 1.5 °C/W R_θJC supports effective heat transfer to the PCB heatsink.

Is MBRS16100H suitable for reverse battery protection in 24 V commercial vehicles?

Yes, MBRS16100H is suitable for reverse battery protection in 24 V systems. Its 100 V V_RRM exceeds typical 24 V system transients (e.g., load dump up to 60 V), and its 150 A I_FSM withstands short-duration reverse-polarity faults. AEC-Q101 qualification further validates its robustness for commercial vehicle applications beyond passenger cars.

Does MBRS16100H have a halogen-free and RoHS-compliant construction?

Yes, MBRS16100H is both halogen-free per IEC 61249-2-21 and RoHS compliant, as confirmed in the official datasheet's "Features" section. These environmental certifications ensure compliance with global automotive and industrial regulatory requirements, including EU directives and major OEM substance restrictions.

What is the forward voltage of MBRS16100H at 125°C and full rated current?

At 16 A and 125°C junction temperature, the MBRS16100H exhibits a maximum forward voltage (V_F) of 0.82 V, per the Electrical Specifications table. This low, temperature-stable VF ensures predictable conduction loss and thermal stability in high-ambient environments such as engine control units or power distribution modules.

Can MBRS16100H be used in place of MBRS1690H in an existing design?

Yes, MBRS16100H can replace MBRS1690H in most cases, as both share identical package (TO-263AB), pinout, and thermal characteristics. The key difference is V_RRM: 100 V vs. 90 V. Using MBRS16100H provides 10 V additional reverse margin, enhancing robustness against voltage transients without layout or thermal redesign-provided the original design does not rely on tighter leakage or VF trade-offs unique to the 90 V variant.
