Product Specification

Functions

• High - Voltage Capability: It features a breakdown voltage of 650 V, enabling it to handle high - voltage power supply systems.
• This high - voltage tolerance allows the IKW50N65F5 to be used in applications where the power supply voltage may reach or approach 650 V, such as industrial power supplies and some high - voltage motor - drive systems.
• Low - Loss Characteristics: Compared with the best - in - class high - speed 3 - family IGBTs, it has 2.5 times lower gate charge (Qg), a 2 - fold reduction in switching losses, and a 200 - mV reduction in collector - emitter saturation voltage (Vcesat). These characteristics result in lower power losses during operation, leading to higher efficiency and reduced heat generation.
• Fast Switching Speed: The IKW50N65F5 has a relatively fast switching speed, which allows it to quickly turn on and off, enabling efficient control of power in applications that require high - frequency switching, such as inverters and switching power supplies.
• Integrated Diode: It is co - packed with a rapid silicon - diode technology. This integrated diode provides a free - wheeling path for the inductive load current, which helps protect the IGBT from voltage spikes and enables efficient operation in various circuit topologies.
• Temperature Stability: It has a mild positive temperature coefficient of Vcesat and good temperature stability of the forward voltage (Vf) of the integrated diode. This means that its performance changes little with temperature variations, ensuring reliable operation over a wide temperature range.

Applications

• Uninterruptible Power Supply (UPS) Systems: In UPS systems, the IKW50N65F5 is used in the inverter section to convert the DC power from the battery to AC power to supply power to the load. Its high - voltage capability, low - loss characteristics, and fast switching speed enable efficient and reliable power conversion, ensuring a stable power supply during power outages.
• Industrial Heating and Welding1: For industrial heating and welding equipment, the IKW50N65F5 can be used in the power - control circuits. It can accurately control the output power by adjusting the switching frequency and duty cycle, providing the necessary heat energy for processes such as induction heating and resistance welding.
• Motor - Drive Systems: In industrial motor - drive applications, the IKW50N65F5 is used in the inverter to convert DC power to variable - frequency AC power to drive motors. Its fast switching speed and low - loss characteristics help improve the efficiency and dynamic performance of the motor - drive system, while its high - voltage capability can meet the requirements of high - power motor drives.
• Power Factor Correction (PFC) Circuits: The IKW50N65F5 can be used in PFC circuits to improve the power factor of AC - DC power supplies. By controlling the switching of the IGBT, the input current can be shaped to be in phase with the input voltage, reducing harmonic distortion and improving the efficiency of the power supply.
• DC - DC Converters: In some applications that require DC - DC conversion, such as in industrial automation and telecommunications equipment, the IKW50N65F5 can be used as a switching element in the DC - DC converter. Its high - voltage and high - current capabilities, along with its low - loss characteristics, enable efficient conversion of DC power from one voltage level to another.
