  • What is thermal resistance Rth?
    • This refers to the thermal resistance based on heat generated at the PN (or Schottky) junction. Specifically, Rth(j-a) is the thermal resistance from the junction to ambient and Rth(j-c) signifies the resistance from the junction to the terminal. The graph below is useful to determining Tj (junction temperature) during operation. Please note that Rth may vary depending on the size of the land pattern and board materials.
