How does a silicon controlled rectifier work?
A silicon controlled rectifier (SCR) is a four-layer power semiconductor device. The term ‘silicon controlled rectifier’ was coined by General Electric when SCRs were first introduced in 1957. Like rectifiers, SCRs are unidirectional devices. Today, SCRs are recognized as a type of thyristor. Other types of thyristors, such as triacs, are inherently bidirectional. This FAQ […]
Half-bridge 650-V GaN-on-silicon power circuit handles up to 3 kW
Wise-integration, a pioneer in digital control of gallium-nitride (GaN) power supplies and GaN ICs, has launched its first commercial product: the 120mOhm WI62120 half-bridge power circuit, providing power electronics designers with new levels of power density, performance, and cost-effectiveness. The JEDEC-certified WI62120, a 650V enhancement-mode GaN-on-silicon integrated circuit, is part of Wise-integration’s WiseGan family of power […]
Compact eGaN FETs target high power density converter apps
Efficient Power Conversion Corporation expands the selection of low voltage, off-the-shelf gallium nitride transistors with the introduction of the EPC2066 (0.8 mΩ typical, 40 V) GaN FET. The low losses and small size of the EPC2066 make it the ideal switch for the secondary side of high power density 40 V – 60 V to […]
IEEE International Electron Devices Meeting (IEDM) announces 2022 call for papers
Under the theme, “The 75th anniversary of the Transistor and the Next Transformative Devices to Address Global Challenges,” the 68th annual IEEE International Electron Devices Meeting (IEDM) has issued a Call for Papers seeking the world’s best original work in all areas of microelectronics research and development. The 2022 IEDM is being planned as an […]
How big is the band gap? A heated discussion
There’s a trick with a soldering iron can be used to determine whether an unidentified semiconductor is n-type or p-type. In essence, it determines whether the majority carriers are holes (p-type) or electrons (n-type). Just as heat makes a gas expand (PV=nRT), the hot tip of a soldering iron makes carriers expand away from the […]
Biodegradable electronics: Help for the waste problem
The fast pace of technology results in tremendous amounts of waste. New research into biodegradable electronics could reduce waste, both at manufacturing processes and in end-of-life trash
