Semiconducting Devices Question 32

Question: In PN-junction diode the reverse saturation current is 105 amp at 27C. The forward current for a voltage of 0.2volt is

[MP PMT 1993]

Options:

A) 2037.6×103amp

B) 203.76×103amp

C) 20.376×103amp

D) 2.0376×103amp

[exp(7.62)=2038.6,K=1.4×1023J/K]

Show Answer

Answer:

Correct Answer: C

Solution:

The forward current i=is(eeV/kT1)=105[e1.6×1019×0.21.4×1023×3001]

=105[2038.61]=20.376×103A
