IGBTs are power transistors that combine the advantages of both transistors and thyristors into a single component. They have the high speed switching characteristics of a transistor, but also have low turn-on/off losses like a thyristor. APT25GR120SD15 is one type of IGBT, and it is widely used in various applications thanks to its high current and voltage ratings, as well as its low switching losses.

The APT25GR120SD15 component is a discrete IGBT module with a DC collector current rating of 25A, a DC collector-emitter voltage rating of 1200V, and a gate-emitter voltage rating of 15V. The component includes a pre-biased free wheeling diode, as well as a so-called ‘desaturation detection’ module to protect against excessive operational losses. It has a pre-charged output gate and an integral gate drive circuit, making it ideal for high-side switching applications.

APT25GR120SD15 IGBTs are often used in applications such as motor drives, power supplies and inverters, in which they have low losses and can switch high currents and voltages reliably. The devices are well-suited to applications such as DC-DC converters and resonant converters, and are especially advantageous in applications with high output currents, high gate drive voltage requirements, or in applications that require fast switching.

The working principle of APT25GR120SD15 IGBTs is similar to a standard transistor, with the addition of an additional gate terminal allowing the device to be turned off in the same way as a thyristor. When the gate is positive (compared with the emitter), the device will conduct current, allowing the device to amplify the input signal. When the gate voltage drops to below the threshold voltage, the device will switch off, resulting in a low power dissipation. The pre-biased free wheeling diode helps prevent excessive power dissipation by ensuring that a short circuit does not form between the collector and the emitter.

Overall, the APT25GR120SD15 is a powerful, reliable and energy-efficient IGBT component which can be used in many different applications. Its high current and voltage ratings, as well as its low switching losses, make this component well-suited for use in motor drives, power supplies and inverters, as well as other power electronics applications.
