Is there an off-the-shelf heat sink that will work with the PTN78020W?

    Jorden:

    The PTN78020W is not recommended to have any external  heat sink for improved thermal performance. The PCB component   layout is not optimized for heat sinks.

    Thepublished  temperature derating(SOA) at different output voltages versus output current indicates with increased air flow  to 200LFM from natural airflow  will  improve the SOA derating limits by 6-8°.
