FP50R12KT4-B11

General Introduction

The FP50R12KT4 – B11 is an Insulated – Gate Bipolar Transistor (IGBT) module developed by Infineon. It combines the advantages of MOSFETs (Metal – Oxide – Semiconductor Field – Effect Transistors) and bipolar junction transistors, offering high – power switching capabilities for a variety of applications.

Electrical Characteristics

Voltage Rating: It has a collector – emitter voltage rating ( $V_{CES}$ ) of 1200 V. This high – voltage rating makes it suitable for high – power applications that require handling large electrical potentials, such as in industrial power converters and high – voltage motor drives.
Current Rating: The module can handle a continuous collector current ( $I_{C}$ ) of 50 A. This current – handling capacity enables it to drive high – power loads, like large – scale motors or high – power electrical equipment.
Low Saturation Voltage: It features a relatively low saturation voltage ( $V_{CE (s a t)}$ ). A low saturation voltage means less power is dissipated as heat during the on – state of the IGBT, resulting in higher efficiency and reduced cooling requirements for the overall system.

Switching Performance

Fast Switching Speed: The FP50R12KT4 – B11 has fast turn – on and turn – off times. This fast switching ability is crucial for applications that require high – frequency operation, such as in modern power – electronics systems where rapid switching helps in achieving better power – conversion efficiency and reducing the size of passive components.
Soft Switching Characteristics: It also exhibits soft – switching behavior, which helps to reduce electromagnetic interference (EMI) and stress on the device during the switching process. This is beneficial for maintaining the reliability of the module and the overall system.

Thermal Management

Efficient Heat Dissipation: The module is designed with a good thermal – management structure. It has a low thermal resistance between the junction and the case ( $R_{t h (j - c)}$ ), allowing heat to be effectively transferred from the IGBT die to the external heat sink. This ensures that the module can operate within its specified temperature range even under high – power – dissipation conditions.

Package and Mounting

Compact Package Design: It comes in a specific package that is designed to be compact and easy to mount on a printed – circuit board (PCB) or a heat sink. The package provides mechanical protection for the internal components and also facilitates electrical connections to the external circuit.

Applications

Industrial Motor Drives: In industrial settings, it is widely used in motor – drive systems. It can control the speed and torque of large – and medium – sized motors, enabling precise control of industrial machinery such as conveyor belts, pumps, and fans.
Renewable Energy Systems: It is suitable for use in renewable – energy applications, such as solar inverters and wind – power converters. In solar inverters, it helps to convert the DC power generated by solar panels into AC power that can be fed into the grid. In wind – power converters, it is used for power conversion and control in the wind – turbine generator system.
Uninterruptible Power Supplies (UPS): The FP50R12KT4 – B11 can be used in UPS systems to provide backup power during power outages. It helps in converting the DC power stored in batteries into AC power to supply critical loads, ensuring the continuous operation of sensitive equipment like computers and servers.
