Junction Transistor
Given below are two statements:
Statement I: In a typical transistor, all three regions emitter, base and collector have same doping level.
Statement II: In a transistor, collector is the thickest and base is the thinnest segment. In the light of the above statements, choose the most appropriate answer from the options given below.
Show answer and solution
Answer: (c)
- Statement I: doping differs; emitter is heavily doped, base lightly, collector moderately. So I is incorrect.
- Statement II: collector is the largest (to remove heat) and base is the thinnest. So II is correct.
- So the answer is (c) Statement I is incorrect but Statement II is correct.
