What is a MOSFET? PANJIT Technology Applications for Engineers

MOSFETs on a blue background. Learn more about MOSFETs and Panjit at Sourcengine.

"Editor's Note: This blog was originally published on July 5, 2019 but it has been updated for accuracy and relevance."

The MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a type of semiconductor widely used for switching and amplifying electronic signals. The transistors are commonly used in modern integrated circuits (ICs) because their microscopic size allows them to be packaged in a single chip.

MOSFETs features four terminals; source(S), gate (G), drain (D), body (B), and a dielectric layer for insulation. The device's body is frequently connected to the source, making it a three-terminal field-effect transistor. That means it can direct current flow by controlling the electrical field.

This very amusing video breaks down exactly how MOSFETs work:

Because of their unique characteristics, MOSFETs can be used in analog and digital circuits and have applications in the automotive, computing, transport, telecommunications, gaming, and mobile device sectors. Since its inception in 1947, the MOSFET has gone on to become the most frequently manufactured electronic component of all time.

Unfortunately, MOSFETs became pretty hard to find amid the ongoing global chip shortage. After the COVID-19 began, a supply-demand imbalance emerged in the automotive sector and rapidly spilled out into over 169 industries. Manufacturers and their foundry service partners are working hard to ease the bottleneck by ramping up production. But availability and pricing volatility remain major challenges across the semiconductor market in mid-2022.

Thankfully, PANJIT offers ample quantities of various MOSFETs with short lead times. Its portfolio features multiple circuit configurations, including high-speed, high-performance, low resistance, and small package sizes. The versatility of its offerings enables engineers to optimize their IC designs.

For example, the chipmaker developed advanced high-density cell design and trench structure for its devices. Therefore, when used in a synchronous-rectification DC/DC converter, its MOSFETs provide lower than usual power dissipation and switching losses.

Furthermore, PANJIT's MOSFETs are available in three categories: Low Voltage, Medium Voltage, and Power. That gives buyers and design teams a wide range of options to choose from when pursuing different end markets.
