IKW40N65F5FKSA1 Device - Application Field and Working Principle

The IKW40N65F5FKSA1 from Infineon Technologies is an Insulated Gate Bipolar Transistor (IGBT) module based on the company’s seventh-generation Trench Stop IGBT4 CoolMOS technology. It is part of the 700 V CoolMOS C7 family, with a current Rating of 40 A. This makes it suitable for applications such as motor drives and solar inverters, where fast switching with low losses is a key feature.

Application Field

The IKW40N65F5FKSA1 is designed for applications that need high current rating and a wide voltage range. It is suitable for hard switching applications such as variable speed drives, uninterruptible power supplies, servers, telecom systems, and solar inverters. Its low turn-on delay time enhances current density, making it an ideal choice for high switching frequency applications where flux losses must be minimized.

The high speed capability of the IKW40N65F5FKSA1 allows for high frequency switching and improved efficiency in motor drive applications. It can also be used in motor control applications due to its low switching losses. This eliminates the need for snubber networks, resulting in fewer external components and a more concise design.

The IKW40N65F5FKSA1 is designed for high reliability and is ideal for applications requiring long life, such as AC drives and UPS systems. Its air-cooled design makes it suitable for use in confined spaces, such as a motor cabinet. Its efficient package size makes it perfect for denser board layouts, decreasing board complexity and minimizing the total cost of ownership.

Working Principles

The IKW40N65F5FKSA1 is an N-channel IGBT4 module with a built-in fast re-latch feature. This feature ensures reliable operation at high frequencies, allowing for higher speeds and improved efficiency. The device is designed for optimized switching performance and has a low collector-emitter saturation voltage (Vce(sat)) of 1.8 V at 20 A. This ensures fast switching with low losses.

The device also features an integrated temperature monitor which provides an indication of the operating temperature of the module. This monitoring feature allows the user to be aware of the module’s temperature and minimize thermal problems in the system. The IKW40N65F5FKSA1’s robust isolated package offers protection against static and transient overvoltage, as well as extended creepage distance.

The IKW40N65F5FKSA1 is designed with Infineon’s 700 V optimized system standard and Ultra Fast Soft Recovery (UFEM) concept. The device provides superior system performance, increased efficiency, and improved reliability. Its unparalleled surge withstand capability and short switching times result in very low switching losses and improved overall system performance.

The IKW40N65F5FKSA1 from Infineon Technologies is an ideal choice for a wide range of applications where high current rating and wide voltage range are required. Its advanced features and robust package make it suitable for motor drives, UPS systems, and many other applications.
