FYI, based on some recent repairs I've done, I want to brain dump this here so that it might help someone else:
The flipper coils have the part number for not having a diode (-ND). In spite of that, the original flipper coils have a diode installed. It's important when replacing a flipper coil you need to make sure a diode is installed. For most of the other coils, the diodes are installed on the node board. For whatever reasons, the diodes for the flippers are NOT installed on the node board and are installed on the coil. You will blow a transistor (MOSFET) if you don't have a diode.
The driver transistors used on the node board are IPD30N10S3L34ATMA1 (Infineon Technologies, MOSFET N Channel, 100V, 30A, TO-252-3 package). For those with a hot air rework soldering station, wrap the white connectors with foil to keep them from melting.
