Working Principle

The STP18N65M5 is an N-channel power MOSFET that belongs to the Power MOSFET family of transistors by STMicroelectronics. It is designed with a MOSFET structure to allow for fast switching performance and excellent power efficiency. The device works on the principle of the MOSFET, where a MOSFET is made of two main parts: the source and the drain. When a voltage is applied to the gate of the MOSFET, the electrical field generated will open the gate, allowing electrons to flow from the source to the drain. This allows current to flow through the device, and it is then dissipated as heat. The current through the MOSFET is controlled by the gate voltage, allowing the user to control the power dissipation of the device.

The STP18N65M5 also has a built-in ESD protection circuit, which helps to protect the device from harm due to electrostatic discharge. This protection circuit is designed to activate when the ESD voltage reaches a certain level and will help to prevent damage due to ESD. The device also has a built-in thermal shutdown circuit, which helps to protect the device from overheating.

The STP18N65M5 has a wide variety of applications, such as controlling motors, DC/DC convertors, and high-current switching. It is designed with advanced process technology to provide fast switching performance and excellent power efficiency, making it an ideal device for many applications.
