The STP20NM60FD is designed for applications that require high efficiency, low power loss, and a wide variety of features. It features a very low on-resistance, as well as integrated protection features such as over-temperature and over-voltage protection.

Working Principle

Field-effect transistors, such as the STP20NM60FD, operate on the principle of a semiconductor device which relies on the flow of electrons in a channel formed by charge carriers in the device. The device contains two terminals, referred to as the source and the drain, and a third terminal, called the gate. The gate controls the conductivity of the channel between the source and the drain by the application of a voltage. Unlike a traditional bipolar junction transistor, the FET does not rely on current flowing between the gate and the source in order to control the on/off state of the channel, but instead relies on the electric field between the gate and the source.

In the case of the STP20NM60FD, it is a N-channel MOSFET, which means that the channel is formed between the source and the drain by negative charge carriers, namely electrons. When the gate voltage is applied above a certain threshold value, the electrons in the channel are “pinned”, effectively creating an electron-rich region between the source and the drain, and allowing current to flow.

The STP20NM60FD also features a very low on-resistance, which means that it has low power losses when it is “on”. This makes it suitable for applications that require high efficiency and low power losses, such as DC-DC converters and H-bridge circuits.

Conclusion

The STP20NM60FD is a power MOSFET which is suitable for a wide range of applications, from industrial to automotive. It is a 500V field-effect transistor manufactured with ST\'s advanced BCDMOS technology, allowing it to offer low on-resistance and integrated protection features. The STP20NM60FD operates on the principle of a semiconductor device relying on electrons flowing in a channel created by the application of a voltage between the gate and the source. In summary, the STP20NM60FD is a robust and reliable power transistor suitable for a wide range of applications.
