FGA15N120FTDTU Working Principle

The FGA15N120FTDTU utilizes an insulated-gate bipolar transistor (IGBT) design to drive the load. This device has a very low turn-on voltage and can be used in a variety of applications due to its high efficiency and simple design. When a voltage is applied across the gate and the emitter of the FGA15N120FTDTU, it produces a controlled flow of electrical current. This current flow is regulated by the gate voltage and its junction temperature, which is monitored and controlled by an internal temperature sensor. As current is applied to the gate, it turns on the device and ultimately regulates how much current is drawn from the source. The FGA15N120FTDTU can be used to drive both AC and DC power supplies with high efficiency.

The FGA15N120FTDTU is also designed to handle higher chucking levels than standard IGBTs in order to meet the demands of the more rugged applications. This increased chucking efficiency prevents long-term device damage during high-current events. The FGA15N120FTDTU is designed for use with a wide variety of gate driver circuits, providing deep integration into power electronic designs.

Conclusion

The FGA15N120FTDTU is a low-cost, short-circuit rated transistor with excellent dynamic characteristics and an extremely low gate-emitter voltage. This device is ideal for a variety of applications, including motor drive, high-frequency power conversion, solar power, UPS systems, and DC chopper and buck converters.
