A copackaged electronic device comprises a diode device having an anode coupled to a drain electrode of a switching device and a cathode capable of being coupled to an external circuit. The switching device may be controlled by an integrated circuit mounted on a source electrode of the switching device and electrically connected such that the integrated circuit is capable of controlling switching of the switching device. For example, the device is used in a power factor correction circuit. The diode device comprises at least one inverted diode having a solderable anode and a wire-bondable cathode.

Co-packaged control circuit, transistor and inverted diode

Two series-connected diodes which are housed in a power package (such as but not limited to TO220, TO220FP, D2pak, TO247, etc.).

Semiconductor package for series-connected diodes

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.
