BUL128D-B Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the BUL128D-B is -40°C to 150°C.
  • To ensure reliability, follow the recommended derating curves, and consider using a heat sink or thermal interface material to reduce the junction temperature.
  • Use a multi-layer PCB with a solid ground plane, keep the layout symmetrical, and minimize track lengths and loops to reduce EMI.
  • No, the BUL128D-B is rated for a maximum voltage of 100V. Exceeding this voltage may damage the device.
  • 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.
