Alternator Heat Sink Assembly

Heat Sink Assembly 23109-99203 is a genuine electrical component used in Nissan Diesel alternators.

It functions as a rectifier diode plate and heat dissipation unit, converting AC current generated by the alternator into DC power to charge the battery while dissipating excess heat produced by the diodes.

Manufactured from high-quality aluminum with integrated rectifier diodes, this assembly ensures stable electrical performance, efficient cooling, and long service life in heavy-duty diesel engines.
