HVLED805TR datasheet by STMicroelectronics

HVLED805TR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for HVLED805TR to ensure optimal thermal performance?
  STMicroelectronics recommends a PCB layout with a large copper area connected to the thermal pad of the HVLED805TR to dissipate heat efficiently. A minimum of 2oz copper thickness and a thermal via array under the device are also recommended.
• How do I ensure the HVLED805TR is properly biased for optimal performance?
  The HVLED805TR requires a bias voltage of 12V to 15V on the VCC pin, and a bias current of 10mA to 20mA on the IBIAS pin. Ensure that the bias voltage and current are within the recommended range to achieve optimal performance.
• What is the maximum allowable voltage on the output pins of HVLED805TR?
  The maximum allowable voltage on the output pins of HVLED805TR is 80V. Exceeding this voltage may damage the device.
• Can I use HVLED805TR in a high-temperature environment?
  Yes, HVLED805TR is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly cooled and the operating temperature is within the recommended range.
• How do I troubleshoot issues with HVLED805TR, such as output voltage not reaching the expected level?
  Check the input voltage, bias voltage, and bias current to ensure they are within the recommended range. Verify that the PCB layout is correct and the device is properly cooled. Use an oscilloscope to check the output voltage waveform and ensure it is not oscillating or distorted.
