MCQ
For germanium diode, the junction voltage is about $.......$
- A$0.7V$
- ✓$0.3$
- C$0.6V$
- D$3V$
✓
Answer
Correct option: B.
$0.3$
The junction voltage $Vo$ for a germanium diode is $0.3\ V$ at room temperature. This potential opposes the diffusion of electrons from $n-$side and holes from $p-$side. It is $0.7\ eV$ for $Si$ at room temperature.
