Formula to calc Id of this IRF3205 in the linear region from this specific voltage measure point

The current in each MOSFET is the voltage across the source resistor divided by the value of the resistor. It is assumed that the gate current is negligible. In the schematic shown the source resistor ...

Why is this transistor in my bootstrap driver failing?

It appears your breadboard has the transistors wired incorrectly. The 2N5551 & 2N5401 datasheets show a EBC pinout (looking at the front face) but you have wired as CBE. From memory the CBE is the ...

Why is this transistor in my bootstrap driver failing?

A couple of items in the design are not ideal: The upper transistor is not driven heavily enough. When the input transistor is turned off current from the 6.8k resistor will enter the base of the ...

Why is this transistor in my bootstrap driver failing?

First: Your input transistor is likely missing a base resistor. You do want a base resistor if your control signal is a voltage (as opposed to a current). Your schematic looks reasonable. Your problem ...
