Integrally formed rectifier for internal alternator regulator (IAR) style alternator

A rectifier for an alternator comprising:

• an integrally formed, one-piece metallic rectifier body having an outer cooling surface and a planar configured ground engaging surface that is configured for mounting within an alternator and being grounded through an automotive grounding system and provide a heat sink surface, a diode receiving cavity opposite the ground engaging surface, and a plurality of cooling fins formed on the outer surface of the rectifier body to enhance cooling of the rectifier body;
• a plurality of negative diodes secured within the diode receiving cavity and grounded thereto;
• an insulated conductive substrate positioned in the diode receiving cavity and having a conductive surface that is insulated from the rectifier body;
• a plurality of positive diodes secured on the insulated conductive substrate;
• a terminal connector interconnecting negative and positive diodes in an electrical rectifying configuration;
• and
• a connector housing secured to the rectifier body that connects the terminal connector and receives a wiring harness.
