Taiwan Semiconductor Corporation MBR16100

Overview

MBR16100 from Taiwan Semiconductor is a 16A, 100V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.85 V at 16 A, 25°C), high surge current capability (150 A), and junction-to-case thermal resistance of 3°C/W. It serves as a primary output rectifier in high-efficiency DC-DC converters and industrial SMPS.

For engineers reviewing the MBR16100 datasheet, MBR16100 pinout, MBR16100 application, or MBR16100 equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 7.5 mA reverse leakage at 125°C, AEC-Q101 qualification option, RoHS/halogen-free compliance, and TO-220AC mechanical mounting requirements.

Technical Context

This single-die Schottky rectifier uses a guard ring structure to enhance overvoltage robustness and supports continuous conduction mode operation with 150°C maximum junction temperature. Its 10,000 V/µs dV/dt rating enables stable switching in fast-rising edge environments such as synchronous rectification circuits.

The device delivers 32 A peak repetitive forward current under square-wave 20 kHz excitation and maintains low conduction loss across -55°C to +150°C operating range, making it suitable for thermally constrained power stages where thermal cycling reliability is critical.

FAQ

What is the maximum junction temperature rating for the MBR16100?

The MBR16100 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows reliable operation in sealed or high-ambient environments such as industrial motor drives and outdoor LED lighting systems. The MBR16100 maintains specified electrical parameters up to this limit when thermal design ensures junction-to-case temperature rise stays within 3°C/W × power dissipation.

Does the MBR16100 have AEC-Q101 qualification?

The standard MBR16100 is not AEC-Q101 qualified, but the variant MBR16100H is explicitly listed in Taiwan Semiconductor's ordering information as AEC-Q101 qualified. This qualification covers temperature cycling, humidity testing, and mechanical shock per automotive grade 2 requirements. Engineers selecting MBR16100 for automotive use must specify the 'H' suffix to ensure compliance.

What is the forward voltage of the MBR16100 at elevated temperature?

At 16 A and 125°C junction temperature, the MBR16100 exhibits a typical forward voltage of 0.75 V, as confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This represents a reduction from the 25°C value (0.85 V), reflecting the negative temperature coefficient of Schottky diodes. Designers should use this value for worst-case conduction loss calculation in high-temperature operating conditions.

How does the MBR16100 compare to the MBR1690 in terms of reverse leakage?

At rated 100 V reverse voltage and 125°C, the MBR16100 specifies 7.5 mA maximum reverse leakage current, whereas the MBR1690 (90 V version) specifies 10 mA under identical conditions. This 25% lower leakage improves efficiency in high-temperature standby modes and reduces thermal stress in tightly packed power modules. Both share identical package, pinout, and thermal resistance, making MBR16100 a direct upgrade where higher V_RRM margin is needed.

What is the mounting torque specification for the MBR16100 TO-220AC package?

The MBR16100 TO-220AC package specifies a maximum mounting torque of 0.56 N·m for the securing screw, as documented in the Mechanical Data section of the Taiwan Semiconductor datasheet. Exceeding this value risks cracking the epoxy body or damaging the internal bond wires. Proper torque control ensures optimal thermal contact between the metal tab and heatsink while preserving mechanical integrity across thermal cycling.
