Alternator Rectifier / Heat Sink

The Nissan Diesel 23109-NY001 Heat Sink Assembly is a rectifier plate used in the vehicle alternator. It contains multiple diodes mounted on an aluminum heat sink that converts AC current generated by the alternator into DC current to charge the vehicle battery and power the electrical system.

The aluminum plate acts as a heat sink to dissipate heat generated by the diodes, ensuring stable alternator performance and preventing electrical damage. This component is commonly used in Nissan Diesel / UD Trucks charging systems.
