DESCRIPTION
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 Microtechnology 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.
The PA03 also features a laser trimmed high performance
FET input stage providing superior DC accuracies both initially
and over the full temperature range.

The PA03 output power stages contain fast reverse recovery
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.
IMPORTANT: Observe mounting precautions.

NOTES: * The specification of PA03A is identical to the specification for PA03 in applicable column to the left.
1. Long term operation at the maximum junction temperature will result in reduced product life. Derate power dissipation to achieve
high MTTF.
2. The power supply voltage for all specifications is the TYP rating unless noted as a test condition.
