DESCRIPTION
The super power PA03 advances the state of the art in both
brute force power and self protection against abnormal oper-
ating conditions. Its features start with a copper dip package
developed by Apex to extend power capabilities well beyond
those attainable with the familiar TO-3 package. The in-
creased 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 tem-
peratures and with a response time of less than ten millisec-
onds 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 recov-
ery 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. Ultrasoni-
cally bonded aluminum wires provide reliable interconnec-
tions 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.
3. +VS and –VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to –VS.
4. Rating applies if both shutdown inputs are least 1V inside supply rails. If one of the shutdown inputs is tied to a supply rail, the
current in that pin may increase to 2.4mA.
5. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz.
6. The PA03 must be used with a heatsink or the quiescent power may drive the unit into thermal shutdown.
CAUTION
The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or
subject to temperatures in excess of 850°C to avoid generating toxic fumes.
