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 […]
