PA03 - 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

PA03 Frequently Asked Questions (FAQs)

  • A good PCB layout for the PA03 involves keeping the input and output traces short and wide, using a solid ground plane, and placing decoupling capacitors close to the device. Apex Microtechnology provides a recommended PCB layout in their application notes.
  • To protect the PA03, use voltage regulators and current limiters to prevent overvoltage and overcurrent conditions. Additionally, consider adding overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the device.
  • To manage heat, use a heat sink with a thermal interface material (TIM) and ensure good airflow around the device. Apex Microtechnology recommends a maximum junction temperature of 150°C for the PA03.
  • Yes, the PA03 is suitable for high-reliability and aerospace applications. Apex Microtechnology offers a range of screening options, including burn-in and environmental testing, to ensure the device meets the required standards.
  • To troubleshoot issues with the PA03, check the PCB layout, decoupling, and component selection. Ensure that the input and output impedances are matched, and the device is operated within its recommended specifications. Consult Apex Microtechnology's application notes and technical support for further assistance.
