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 package 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 milliseconds 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.
OBJECT TOOL
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. Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The MO-127 Copper, 12-pin Power DipTM package (see Package Outlines), is hermetically sealed and isolated from the internal circuits. Insulating washers are not recommended. IMPORTANT: Observe mounting precautions.

CAUTION
The specification of PA03A is identical to the specification for PA03 in applicable column to the left. Long term operation at the maximum junction temperature will result in reduced product life. Derate power dissipation to achieve high MTTF. The power supply voltage for all specifications is the TYP rating unless noted as a test condition. +VS and VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to VS. 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. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz. The PA03 must be used with a heatsink or the quiescent power may drive the unit into thermal shutdown. 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.
