BUL128D-B datasheet by STMicroelectronics

BUL128D-B Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the BUL128D-B?
  The maximum operating temperature range for the BUL128D-B is -40°C to 150°C.
• How do I ensure the reliability of the BUL128D-B in high-temperature applications?
  To ensure reliability, follow the recommended derating curves, and consider using a heat sink or thermal interface material to reduce the junction temperature.
• What is the recommended PCB layout for the BUL128D-B to minimize electromagnetic interference (EMI)?
  Use a multi-layer PCB with a solid ground plane, keep the layout symmetrical, and minimize track lengths and loops to reduce EMI.
• Can I use the BUL128D-B in a high-voltage application above 100V?
  No, the BUL128D-B is rated for a maximum voltage of 100V. Exceeding this voltage may damage the device.
• How do I protect the BUL128D-B from electrical overstress (EOS)?
  Use a transient voltage suppressor (TVS) or a zener diode to clamp voltage transients, and ensure the device is operated within its recommended voltage and current ratings.
