Abstract
A diode for use in an under-the-hood automotive application has a TO 220 outline and consists of a diode die on a two piece lead frame which has a thick section to which the bottom of the die is soldered, and a thinner section which extends through a plastic housing as a connection tab and which has a forked end for easy connection to a node of a three phase bridge. The bottom of the thickened section is exposed through the insulation housing for easy connection to a d-c heat sink rail. The diode is particularly useful in applications greater than 2 KW.
