Any type of power discrete
semiconductor die can be bonded onto the copper islands. These islands measure 17.5mm by
24mm. All die mounted on an island will share a common connection - eg common collectors
in the case of bipolar transistors. This feature is useful in fabricating compound
semiconductor structures.
Diodes can also be included,
these frequently being available in either common anode or common cathode types.
Additionally, small driver transistors and diodes can be mounted on the fingers of the
lead frame to give a greater degree of freedom to the circuit designer.
