Protect cellular base stations from electrical hazards
The next generation of cellular communications, the 5G network, will help the IoT reach its full potential. IoT includes many devices and physical objects such as home appliances, vehicles, and “smart” cities. IoT connectivity depends on the advancements of the 5G network compared to the current 4G LTE networks. The download speed of up to […]
UVC emitting diodes offered in ceramic- and quartz-based packages
Vishay Intertechnology, Inc. introduced two new UVC (short wavelength ultraviolet) emitting diodes in a ceramic / quartz-based package for sterilization in medical, industrial, and consumer applications. Compared to previous-generation solutions, the Vishay Semiconductors VLMU35CR40-275-120 and VLMU35CR41-275-120 deliver higher radiant power at a lower cost while offering higher disinfection efficiency and longer service life. The devices […]
What’s the difference between Shockley and Schottky diodes?
Neither a Shockley diode nor a Schottky diode are single p-n junction devices. A Shockley diode has a four-layer thyristor structure with a typical forward drop of 800 mV. It’s called a diode because it has two leads. A Shockley diode is essentially a SCR with the gate not connected. In a Schottky diode a […]
Fast recovery diodes feature low loss, ultra-low noise
ROHM Semiconductor announced its fourth generation 650V fast recovery diodes (FRDs), the RFL/RFS Series, featuring low forward voltage (VF) and fast reverse recovery time (trr), respectively, as well as ultra-low noise characteristics. The new devices are ideal for industrial and consumer equipment that handle large amounts of power, such as air conditioners and EV charging stations. In […]
