I received question mail from my customer as next.
The data sheet of MAT14 says that Cebo: 40pF typ at Vcb=15V, Ie=0, and f=1MHz.
My understanding of the Cebo is base-emitter capacitance at collector is open.
If my understanding is correct, why you state that Vcb=15V?
Mat04 says that Cebo: 40pF typ at Vbe=0V, Ic=0, f=1MHz, this seems reasonable condition.
Could you explain why Vcb=15V condition for the Cebo is stated?
Another question is the bulk resistance specification.
MAT14 rbe=0.4 ohm typ at 10uA<=Ic<=10mA.
For the MAT04, rbe=0.4ohm typ at 10uA<=Ic<=1mA
What is the main reason for this difference?
