What is Schottky Diode? Schottky diode is a device, which comes under the type of a metal – semiconductor junction diode. Barrier diode and low voltage diodes are the other names for Schottky diode. When compared to a PN junction diode, power drop is lower in Schottky diode. A scientist named Walter.H.Schottky first discovered Schottky […]
Tunnel Diode – Working, Characteristics, Applications
What is a Tunnel Diode? A Tunnel Diode is a heavily doped p-n junction diode. The tunnel diode shows negative resistance. When voltage value increases, current flow decreases. Tunnel diode works based on Tunnel Effect. The following image shows the symbol of a Tunnel Diode. Leo Esaki invented Tunnel diode in August 1957. Therefore, it […]
What is a Photodiode? Working, Characteristics, Applications
What is a Photodiode? It is a form of light-weight sensor that converts light energy into electrical voltage or current. Photodiode is a type of semi conducting device with PN junction. Between the p (positive) and n (negative) layers, an intrinsic layer is present. The photo diode accepts light energy as input to generate electric […]
