Overview of the STGWA40N120KD MOSFET

The STGWA40N120KD MOSFET is an N-channel device that features a breakdown voltage of 1200V and a maximum continuous drain current of 40A. It has a low on-resistance of 0.10?, which helps to reduce power losses and improve efficiency. The STGWA40N120KD is also designed with advanced trench-gate technology, which enhances its overall performance and reliability.

Features and Benefits of the STGWA40N120KD MOSFET

One of the key features of the STGWA40N120KD MOSFET is its high voltage rating, which makes it suitable for use in high-power applications. It also has a low gate charge of 76nC, which enables faster switching and reduces switching losses. This MOSFET also has a low gate threshold voltage of around 4.8V, which means it can be easily controlled by standard logic-level MOSFET drivers.

Another benefit of the STGWA40N120KD MOSFET is its low on-resistance, which is an important factor in determining the overall efficiency of a power supply circuit. The lower the on-resistance, the less power is lost as heat, which in turn means more power can be delivered to the load. This MOSFET also has a low gate-drain charge, which reduces the likelihood of parasitic turn-on and improves reliability.

The STGWA40N120KD MOSFET also features a high-temperature performance rating, which makes it suitable for use in harsh environments. It can operate at temperatures of up to 175°C, which means it can handle high-power applications without overheating or breaking down.
