PA03A - Apex Microtechnology

Description: The PA03 is a 30A, 150V power operational amplifier capable of 500 Watts of internal power dissipation thanks to its hermetically sealed, copper MO-127 12-pin metal PowerDIP package. The superior thermal conductivity of copper allows substantially higher power ratings, while the pin count provides additional control features. The PA03 incorporates innovative current limit circuits to minimize internal power dissipation to a curve approximating the safe operating area of the power transistors. The internal

PA03A Frequently Asked Questions (FAQs)

  • Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and thermal vias under the package to dissipate heat. A heat sink or thermal pad can also be used to improve thermal management.
  • To ensure reliable operation at high temperatures, Apex recommends derating the output current and voltage, and using a heat sink or thermal pad to keep the junction temperature below 150°C. Additionally, using a thermally conductive material for the PCB and ensuring good airflow can help.
  • The maximum safe operating area (SOA) for the PA03A is not explicitly stated in the datasheet. However, Apex Microtechnology recommends limiting the output current to 3A and voltage to 30V to ensure reliable operation. Exceeding these limits can lead to device damage or failure.
  • Apex Microtechnology recommends using external protection circuits, such as overvoltage protection (OVP) and overcurrent protection (OCP) circuits, to prevent damage to the PA03A. Additionally, using a fuse or current-limiting resistor can also help protect the device.
  • The typical rise and fall time for the PA03A output is around 10-20 ns, depending on the load and output voltage. However, this can vary depending on the specific application and operating conditions.
