The L6221AD013TR is a power MOSFET array from STMicroelectronics, and is classified under transistors - bipolar (BJT) - arrays. It is designed to be used in power-oriented applications, such as power supplies, motor control and other similar ones.

The L6221AD013TR is composed of two power MOSFETs with a common gate and source terminal, allowing them to be treated as a single component in some situations. It can work with voltages up to 600V, and has a maximum continuous drain current of up to 23A.

To protect the device, STMicroelectronics has designed it with several features. Firstly, it has a built-in temperature sensing system which monitors the junction temperature and restricts it to a safe level. This ensures that the device remains at a safe operating level.

The L6221AD013TR also has a TO-220 package with a copper slug for better thermal performance. This helps dissipate the heat that is generated during operation. Furthermore, it has an internal resistive divider which reduces the switching losses that might otherwise occur.

The working principle of the L6221AD013TR is simple. When a voltage is applied to the gate, a channel of conductive electrons is opened from the source to the drain. This allows current to flow from the source to the drain and this what is used to control the external circuit.

In addition to controlling the external circuit, the L6221AD013TR can also be used to protect it from overvoltage or overcurrent conditions. This is achieved by the use of a built-in overvoltage protection (OVP) system. When the voltage exceeds a certain level, the OVP circuit shuts off the power supply to the external circuit and thus prevents any damage from occurring.

The L6221AD013TR is a very useful device and is ideal for power-oriented applications. Its high voltage and continuous drain current rating, together with its temperature sensing feature and OVP system, make it a great choice for use in such situations.
