The super power PA03 advances the state of the art in

both brute force power and self protection against abnormal

operating conditions. Its features start with a copper dip pack-

age developed by Apex to extend power capabilities well

beyond those attainable with the familiar TO-3 package. The

increased pin count of the new package provides additional

control features, while the superior thermal conductivity of

copper allows substantially higher power ratings.

The PA03 incorporates innovative current limiting circuits

limiting internal power dissipation to a curve approximating

the safe operating area of the power transistors. The internal

current limit of 35A is supplemented with thermal sensing

which reduces the current limit as the substrate temperature

rises. Furthermore, a subcircuit monitors actual junction

temperatures and with a response time of less than ten mil-

liseconds reduces the current limit further to keep the junction

temperature at 175°C.

diodes for sustained high energy ﬂyback protection.

This hybrid integrated circuit utilizes thick ﬁlm resistors,

ceramic capacitors and silicon semiconductors to maximize

reliability, minimize size and give top performance. Ultra-

sonically bonded aluminum wires provide reliable intercon-

nections at all operating temperatures. The MO-127 Copper,

12-pin Power Dip™ package (see Package Outlines), is

hermetically sealed and isolated from the internal circuits.

Insulating washers are not recommended.
