punchthrough bjt
Hi
I've a question about punchthrough of BJT.
When CB depletion region extends further as Vcb increases,
CB depletion region will meet EB depletion region, eventually.
Then, Ic increases increases.
I understand above fact with energy band digram model.
But, I cannot understand another way.
That is..
npn of punchthrough seems to be
Then how current goes through depletion region??
By E-field??
