RFN20NS4SFHTL Frequently Asked Questions (FAQs)

  • ROHM recommends a 4-layer PCB with a solid ground plane, and the use of vias to connect the thermal pad to the ground plane. A minimum of 10mil clearance around the device is recommended to ensure proper heat dissipation.
  • To ensure reliability, ROHM recommends following the derating curve for the device, and using a thermal interface material (TIM) with a thermal conductivity of at least 1W/mK. Additionally, the device should be soldered using a reflow profile with a peak temperature of 260°C or less.
  • Although the datasheet specifies a maximum voltage rating of 20V, ROHM recommends limiting the voltage to 18V or less to ensure long-term reliability and to prevent degradation of the device.
  • Yes, the RFN20NS4SFHTL can be used in switching regulator applications, but ROHM recommends limiting the switching frequency to 500kHz or less to minimize losses and ensure reliable operation.
  • ROHM recommends soldering the thermal pad to the ground plane using a solder paste with a high thermal conductivity. The thermal pad should not be connected to any signal lines or voltage rails.
