The terminals name also implies being taken from both transistors.

. Schottky also known as Schottky barrier diode or hot-carrier diode is a semiconductor diode formed by the junction of a semiconductor with a metal.

This article lists 100 Sensors MCQs for engineering studentsAll the Sensors Questions Answers given below include a hint and wherever possible link to the relevant topic.

It has a low forward voltage drop and a very fast switching action. This is helpful for the users who are preparing for their exams interviews or professionals who would like to brush up their fundamentals on the Sensors topic. A thyristor is a four-layer solid-state semiconductor device that contains 3 PN junctions in series having 3 terminals called anode cathode and gate.

Therefore the NP junction blocks the flow of a positive current from the anode to cathode. It has the ability to control huge current and is generally used. The color of the light corresponding to the energy of the photons is determined by the energy required for electrons to cross the band gap of the.

The Schottky diode named after the German physicist Walter H. Electrons in the semiconductor recombine with electron holes releasing energy in the form of photons Energy packets. Gate terminal as it is the input part taken from MOSFET while the collector and emitter as they are the output taken from the BJT.

The cats-whisker detectors used in the early days of wireless and metal rectifiers used in early. If the anode is a positive terminal with respect to the cathode the outer junctions PN and PN are forward-biased while the center NP junction is reverse-biased. Like a diode a thyristor is a unidirectional device as well but unlike diode it can be used as an open circuit switch.

A light-emitting diode LED is a semiconductor light source that emits light when current flows through it. PN NP and PN. It is a four-layer PNPN device having three PN junctions.

A thyristor with a P-N-P-N structure has three junctions.
