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?
There are possible typos in the electrical table.
Cebo: Test condition should read Vbe = 0V like you mentioned.
MAT14 should also share the same test conditions as MAT04 (10uA<=Ic<=1mA).
Our product engineer would look into this to confirm. We will get back to you after verifying the test conditions.
Thank you for your comment.
Please let us know the test condition verified.
Yes, we verified that there are typos in the electrical table.
