hi, im trying to fix a razor e300 motor controller, please see the post on that.
people tell me that the schottky diode is a likely suspect so i attempted to remove it from a dual layer board by using a heat shunt and laying the flat edge of my soldering iron across all 3 pins. the solder was melting but the bugger wouldnt come out. tried a few more times until the diode was too hot to hold. by then i figured it was trashed but thought id try for confirmation and advice on how i should have removed it. in the end i just broke it off by rocking it back and forth. my multimeter was on 20k ohms. when the red was on the central cathode the meter measured open circuit on both anodes. when the black was on the cathode both the anodes measured 4.50 approx.
as an ameteur i need it confirmed that this is a good (STPS3045CT - a power Schottky rectifier) and how hot i can get it and methods for removing it? to reattatch im going to try and resolder it from the top side of the board.
is the mosfet the next likely suspect in a motor control circuit that cuts out at half load approx?
thanks
