SMF28VTR Frequently Asked Questions (FAQs)

  • ROHM recommends a PCB layout with a solid ground plane, minimal signal trace length, and a 50Ω impedance-matched transmission line to ensure optimal performance and minimize signal reflections.
  • ROHM recommends mounting the device on a heat sink or a metal pad on the PCB to dissipate heat. The device's thermal pad should be connected to a solid ground plane to ensure efficient heat dissipation.
  • ROHM recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a cooling rate of 4°C/s to prevent thermal damage to the device.
  • Yes, SMF28VTR is qualified for automotive and high-reliability applications. ROHM provides a dedicated automotive-grade version of the device, which meets the requirements of the AEC-Q101 standard.
  • ROHM recommends using a moisture-resistant coating or conformal coating on the PCB, and ensuring that the device is stored and operated within the recommended temperature and humidity ranges to prevent moisture ingress and thermal stress.
