I am looking for a replacement part. From what I can gather its a schottky diode. But further googling has lead me to believe its possibly a MOSFET with out the gate connected and using the parasitic diode inherent in MOSFETS. Anyone else have any ideas as to what it is as mine has blown off and I have replaced the MOSFET but the until is no where nearly as powerful. Would this diode improve performance ? I am thinking the B-EMF from the motor is shuting the MOSFET down or the MOSFET I replaced the original with may not be up to spec. I think the replacement was a IRZ44
Anyone got some ideas.
The first picture shows the part circled in red.
the other picture shows the original driver MOSFET.
