A FCA35N60 is a high speed IGBT, a insulated-gate bipolar transistor designed for power switching applications. It is part of the family of FGA25N60 IGBTs and is designed with a typical switching frequency of 1 MHz and 5 A maximum current. Its low on-state resistance ensures high efficiency and reduced losses, while its fast switching speed allows the FCA35N60 to optimize the design of power converters and inverters.

Applications

FCA35N60 IGBTs are widely used for various power applications such as automotive, industrial and communications applications. In automobiles, the FCA35N60 is used to power air-conditioners, window lifts, door locks and other such applications. In the industrial arena, these IGBTs are used for controlling power to machines, power control and switching applications. In communications systems, these IGBTs are used for regulating high power converters and driving audio systems.

Working Principle

The FCA35N60 IGBT operates on the principle of electronic switches. It is a four-terminal device that combines the low gate threshold of a metal-oxide-semiconductor FET (MOSFET) with the low-on-state resistance of a bipolar junction transistor (BJT). In an IGBT, an insulated gate controls the flow of electrons between two traditionally complementary BJT and MOSFET structures. When a voltage is applied to the gate terminal, it causes the MOSFET region to turn on and allow electrons to flow through the structure. When the gate voltage is removed, it causes the BJT structure to turn off and prevent the electrons from flowing.

However, using an IGBT can reduce switching losses and gate charge when compared to MOSFETs or BJTs alone. This is because the IGBT combines the features of both technologies, allowing it to control the current flow when switching between different electrical states without providing a high level of on-state resistance. This reduces power losses in the circuit, making it more efficient.

The FCA35N60 power IGBT also has an integrated Emitter Controlled NPN transistor structure on the chip, which improves the switching performance in comparison to standard IGBTs. This technology reduces the propagation delay time, providing a superior turn-on and turn-off capability. This helps to reduce switching losses, resulting in a more efficient power system design.

Conclusion

The FGA35N60 IGBT is a powerful and versatile device for switching applications. It combines the features of a MOSFET and a BJT to provide a low-resistance and low-loss current control while maintaining high switching speed. Its integrated Emitter Controlled NPN transistor structure further enhances its performance, allowing a more efficient design of power systems. It is used in a variety of applications, ranging from automotive components to communications systems, providing a reliable and efficient power switching solution.
