Correct Answer - Option 1 : 0.47 V
Concept:
For the forward-biased P – N junction, as the temperature increases the forward voltage decreases by 2.5 mV/°C which can be written as
\(\frac{{dv}}{{dt}} = - 2.5\;mV/^\circ C\)
Calculation:
Given, T1 = 25°C and T2 = 75°C
For (75 - 25)°C increase in temperature,
The voltage will decrease by 2.5 × 50 = 125 mV
The voltage across the diode is 600 mV - 125 mV = 475 mV
= 0.475 V
