Diodes: PN Junction, Types, Construction and Working

WebDefinition: Schottky diode is a metal-semiconductor junction which does not store charge carriers at the junction because it has no depletion layer. It finds its application where fast switching is needed. Significance of Schottky diode: When a P-N junction diode is forward biased, it starts conducting, but when it is reverse biased, it stops ... WebSignal diode construction . Small-signal diodes are constructed as PN diodes with a tiny junction area. A smaller junction area gives the diode a smaller junction capacitance. This also reduces the reverse recovery time of the diode to few nanoseconds or less. Small junction capacitance and fast response make the diode suitable for high ... robert walker echol cole https://themarketinghaus.com
