BUL138 Frequently Asked Questions (FAQs)

  • The BUL138 can operate from -40°C to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • The BUL138 requires a minimum of 10V on the VCC pin and a minimum of 5V on the VBB pin to ensure proper biasing. Additionally, the input voltage (VIN) should be within the recommended range of 10V to 18V.
  • To minimize EMI, it is recommended to use a ground plane, keep the input and output tracks as short as possible, and use a shielded cable for the input and output connections. Additionally, the BUL138 should be placed as close as possible to the load to reduce the length of the output tracks.
  • Yes, the BUL138 is qualified for use in high-reliability applications, including automotive and aerospace systems. It meets the requirements of the AEC-Q100 standard for automotive applications and is also suitable for use in aerospace systems.
  • To protect the BUL138 from overvoltage and overcurrent conditions, it is recommended to use a voltage regulator or a voltage limiter on the input, and a current limiter or a fuse on the output. Additionally, the BUL138 has built-in overvoltage and overcurrent protection, but these should not be relied upon as the sole means of protection.
