While semiconductor executives lament slow demand and excess inventories, one sector appears to be resilient: silicon carbide power circuits used in electric vehicles. But companies looking to capitalize on this market could run into complications as they transition to 200 mm wafers, prompting shares of Wolfspeed and STM to fall this week. Power Semiconductor Power semiconductor devices are used to control, amplify and switch the flow of electric current in circuits. To accomplish this task, they feature much higher voltage current ratings compared with signal level semiconductor devices and larger p-n junction areas than signal semiconductors. Power diodes are a subcategory of power semiconductors designed to handle high levels of …

If you want a truly secure grip on your pistol, there are a couple of solutions. Grip tape or epoxying silicon carbide might do the trick. This process uses high performance 2 part epoxy to cover areas where your hands contact the frame, before pouring granules of silicon carbide in any texture that suits you over the epoxy and permanently bonding it to your grip. Made in the USA Silicon carbide textured grips differ from standard stippling by being applied using epoxy and then bonded to the frame, increasing surface area between your hands and grip for improved recoil management and gun control. The kit includes enough materials to customize …

An orchestra of events are necessary to ignite your gas furnace’s furnace flame and reach its target location – sparks from an silicon carbide hot surface ignitor (HSI) are essential in making this happen. HSIs are resistance heaters that glow red hot when voltage is applied. They typically last five to ten years before needing replacement periodically. Low Voltage Silicon carbide hot surface ignitors (HSIs), are responsible for heating up the fuel/air mixture in your furnace so it can ignite. While pilot lights often consume more energy than their furnace counterparts, an HSI will only activate when sent a signal from its control board to do so. With its ability …
