As compared to an ordinary semiconductor diode, a Schottky diode
has higher reverse saturation current
has higher reverse saturation current and higher cut in voltage
has higher reverse saturation current and lower cut in voltage
has lower reverse saturation current and lower cut in voltage
Correct answer is C
This is due to high electron concentration in metals.
Both A and R are true and R is correct explanation of A
Both A and R are true but R is not a correct explanation of A
A is true but R is false
A is false but R is true
Correct answer is A
Avalanche breakdown occurs at high reverse voltage.
As compared to an ordinary semiconductor diode, a Schottky diode
has lower cut in voltage
has higher cut in voltage
lower reverse saturation current
both (b) and (c)
Correct answer is A
Cut in voltage in Schottky diode is about 0.3 V as compared to 0.7 V in ordinary semiconductor diode.
