Transforming switching BJT transistor configurations to MOSFET equivalent ones

[abdulbadii]

Anyone has complete information and table of transforming switching BJT transistor configurations to MOSFET equivalents, for sharing here and now ?

I doubt there's any such table? - just check the datasheets from the manufacturers of the IC's and see what the IC's are designed to drive - 'some' are designed to drive either BJT or FET.

However, in my experience, where the same IC has been used (in different TV models) the FET versions are more expensive and much more unreliable - which was why not many manufacturers used FET's, and those that did soon reverted back.

You cannot, in general, drop a MOSFET into a Bipolar socket, there are
many design differences and considerations to accomplish that transformation.

Advise you study a MOSFET basic operation and characteristics, assuming
you have already done that for Bipolars.

The web has many resources to accomplish this.
