Are the Cob, fT etc. related with hFE as transistor characteristics?

Latest Updated:08/01/2005

Question:

Are the collector capacitance (Cob), transition frequency (fT), etc., correlated with the hFE rank as transistor characteristics?

Answer:

Generally, hFE and collector capacitance (Cob) are not correlated.
On the other hand, the transition frequency (fT) becomes lower if hFE declines because the current gain decreases as hFE decreases.
