Wide band-gap semiconductors are a special class of MPC555LFMZP40R2 materials that have a larger “band gap” than traditional silicon materials. Simply put, wide band-gap semiconductors are able to operate at higher temperatures while also handling higher voltages and power, which makes them very useful in many electronic devices.
These materials are very important in modern technology, especially in areas such as electric vehicles, solar devices, 5G communications and industrial controls. Not only do they make devices run more efficiently, but they also reduce energy consumption and help us build a greener future. In this article, we'll take you through the benefits of wide band-gap semiconductors and where they are used.
Basic Concepts of Band-Gap Semiconductors
A wide band-gap semiconductor is a semiconductor material with a large "forbidden bandwidth". This bandwidth refers to the "energy difference" that electrons need to cross to jump from one energy state to another in the material. Common wide band-gap semiconductors include SiC and GaN.
Wide band-gap materials have several distinct advantages over narrow band-gap semiconductors. They are less prone to failures due to high temperatures and voltages and can better handle high-power tasks. In addition, wide band-gap materials allow devices to operate at higher frequencies, making them suitable for use in high-performance power electronics.
Advantages of Wide Band-Gap Semiconductors
Wide band-gap semiconductors typically have energy bandwidths in excess of 2.3eV (e.g., 3.26eV for silicon carbide, 3.4eV for gallium nitride) and can operate at high temperatures in excess of 300°C, compared to only 1.1eV for silicon.
They have 10 times the breakdown voltage of silicon and can excel in high voltage environments above 1200V.
Gallium nitride has an electron mobility of up to 2000 cm²/V-s, which is faster than silicon's 1500 cm²/V-s.
Silicon carbide has a thermal conductivity of 3.7 W/cm-K, more than twice that of silicon, making it easier for devices to dissipate heat.
Their low on-resistance, such as that of SiC MOSFETs, can be as low as a few milliohms, which reduces energy loss and improves efficiency.
Wide band-gap materials support operating frequencies up to the GHz level, making them particularly suitable for RF and high-speed switching applications, far exceeding silicon's tens of MHz.
