0278.125V Frequently Asked Questions (FAQ)

  • Littelfuse recommends a PCB layout with a solid ground plane and a minimum of 10 mils of clearance around the device to ensure proper heat dissipation and minimize electrical noise.

  • Yes, the 0278.125V is designed to meet the requirements of high-reliability and aerospace applications, but it's recommended to consult with Littelfuse's application engineers to ensure compliance with specific industry standards and regulations.

  • Littelfuse recommends using a heat sink with a thermal interface material (TIM) to ensure efficient heat transfer. The device's thermal pad should be soldered to the heat sink, and the heat sink should be designed to keep the junction temperature below 150°C.

  • Littelfuse recommends a soldering profile with a peak temperature of 260°C and a dwell time of 10-30 seconds to ensure reliable solder joints and minimize thermal stress on the device.

  • Yes, the 0278.125V can be used in a parallel configuration, but it's essential to ensure that the devices are properly matched and that the PCB layout is designed to minimize current imbalance and thermal mismatch between the devices.
