Hi, I need to replace a burnt out component on a drone circuit board (see image)
all 4 transistors are destroyed ( obvious when in the zoomed view of the circuit) ... just that one of them is worse than the others
They appear to be associated with the motor driver circuitry
As to what they are ... type / part number, you would ....
1) contact the manufacturer ... maybe get a full replacement board ... they are unlikely to supply individual parts
2) see if they would provide a circuit schematic
3) at minimum, see if they would give you the transistor part number -- then you would go to a component
supplier like mouser, digikey etc and see if it was available for purchase
Do you have a friend with the same drone ?
maybe they could open their drone and get the part number for you
the above is pretty much your only choices
cheers
Dave
