    IPP90R1K2C3 operating at 116degC junction temperature

    We are using the IPP90R1K2C3 MOSFET in our 60W offline Flyback LED driver. It is dissipating 4W. We measured its metal tab as operating at 110degC. Therefore its junction is operating at 116degC.
    This product is supposed to operate for 8 hours per night , every day of the year.
    For how many years do you think this MOSFET will last?

    This question is about reliability. You will have to request FIT data via this link.
