gents,
I'm looking for a high sped, low capacitance mosfet in a package the size of a to-92 or smaller than a SOIC-8 with the following characteristics.
application:
Attached to a 1:1 push pull transformer with 5V on the CT to generate ~
10V p-p on the output. This means the switching transistors will see at least 10V when the other one is one + leakage inductance spike.Each transistor will turn on between 25 and 50nS each. The peek current during each pulse will be ~ 300mA
When both transistors are off, it is desired that the reflected impedance from the secondary is high hence the reason for low capacitance mosfets.
The MOSFETS I've seen that fit this description usually have very voltage. (Vds ~7V)
Wondering if you guys know of a higher voltage "RF" mosfet for an application like this one.
thanks
