The IRG4PSC71KD is a Solid State Thyristor from International Rectifier Technologies and is a single, isolated IGBT (Insulated Gate Bipolar Transistor). This device is designed for use in power applications such as Motor Control and Inverters, allowing for fast switching and high current, low noise operation. In this article we will explore the application fields and working principles of this device in detail.

The IRG4PSC71KD is designed to handle high power requirements and is capable of delivering a full 18A RMS current with a maximum voltage rating of 600V. The device is rated at 10A peak current and features a high-speed Soft Turn-On feature which allows for smooth switching of the device when used with a Gate turn-on Control Circuit. In addition, the device is able to withstand up to 2750V peak inductive load, making it ideal for use in applications where high-voltage spikes are common. This makes it well suited for use in Motor Control or Inverter applications.

The IRG4PSC71KD features a common emitter IGBT configuration, which consists of three IGBTs connected in series. This configuration allows for a low switching threshold and fast switching times, allowing for fast control. The device is also designed for use in low noise applications, making it suitable for use in audio and video applications where noise reduction is necessary.

The working principle behind the IRG4PSC71KD is based on the principle of Gate Turn-On. This principle states that when a voltage is applied to the Gate turn-on circuit, a high current starts to flow through the device, thus turning it on. The device is controlled by varying the voltage applied to the Gate turn-on circuit, thus allowing for precise control of the power delivered. The device also features a Soft Turn-On feature which enables more precise control by preventing an abrupt surge of current when the device is turned on. This enables a more efficient and reliable operation of the device.

The IRG4PSC71KD is an ideal solution for applications requiring fast switching and high current, low-noise operation. Its high-voltage capabilities, fast switching times and Soft Turn-On feature make it an ideal device for Motor Control and Inverter applications, as well as for audio and video applications where noise reduction is necessary. In addition, the common emitter IGBT configuration ensures a high performance and reliable operation. This makes the IRG4PSC71KD the perfect device for any high power, noise sensitive application.
