Hitachi Ltd. says it has developed a new kind of silicon-carbide-based MOSFET that has dramatically lower on resistance than comparable devices. The new MOSFET uses what Hitachi calls a TED-MOS structure, for Trench-etched DMOS-FET. Compared to conventional DMOS-FET (Double-diffused MOSFET) devices, the new structure is said to reduce electric field strength, an index of durability […]

Demo: Gate drivers and eGaN transistors on the same chip
We recently did a short video with Alex Lidow from EPC who took us through a demonstration of a gate driver integrated onto the same chip as eGaN transistor. Driving the gate of the power transistor is complicated because of the parasitic elements. Lidow explained that eGaN transistors switch in a nanosecond or less, and […]
SiC MOSFETs, diodes are automotive AEC-Q101 qualified, PPAP capable
Wolfspeed announces E-Series, a new family of robust SiC semiconductor devices for the Electric Vehicle (EV) and renewable energy markets that delivers the highest available power density and durability for on-board automotive power conversion systems, off-board charging, solar inverters and other outdoor applications. Wolfspeed’s E-Series family is the first commercial family of SiC MOSFETs and diodes to be […]
Trends in discrete power semiconductors
For many years the rumored demise of the discrete semiconductor has been thrown around, says Joe Beck from Central Semiconductor. Everything’s going to be integrated into an IC. It’s all going away. Not true. In fact, there’s more interest in discrete today than in the last 10 or 15 years, Beck says. When engineers try […]
How eGaN transistor technology improves Lidar performance
Alex Lidow from EPC recently filmed a video with us covering Lidar, a hot subject right now for autonomous vehicles. One of the biggest applications for eGaN is driving these lasers. The reason is that automakers want to see a long distance with a high degree of accuracy. To do that, the laser in a […]
Electrical isolation technology at Silicon Labs
When you’re talking about power products and power supplies, galvanic isolation is a big deal. In that area, Silicon Labs has a wide portfolio of products that cover everything from digital isolators, which allow you to isolate a communication bus, or other digital signals up through high powered gate drivers to allow an interface to […]
Richardson electronics to distribute power semiconductors from MS Power GmbH
Richardson Electronics, Ltd. announced today a new distribution agreement with MS Power GmbH, a manufacturer of bipolar semiconductor products. The agreement aligns with both companies commitment to provide the highest reliability and quality products into various applications including Motor Drives, Power Supplies, Solar and Wind Energy Systems, Smart Grid, and others. MS Power GmbH offers a broad […]
High-temp SCRs block up to 600 V, carry up to 40 A
The SJ Series High-Temperature SCR (Silicon-Controlled Rectifier) Switching Thyristors offers blocking voltages (VDRM) up to 600 V and current ratings from 4 to 40 A to support a wide range of applications. By offering a wider operating margin than earlier SCRs, they make it possible to tolerate insufficient cooling and higher inrush currents at startup. […]
Intelligent power module targets inverters for renewable energy systems
Infineon Technologies AG has optimized its high power intelligent power module (IPM) MIPAQ Pro for the fields of energy storage and smart grid. Customers now profit from complete monitoring and easy scalability of the IPM. Additional features comprise of higher power density, true real-time junction temperature detection and secure authentication. An upgraded smart protection and […]
