    Hi Nandha , Since the UC1834-SP predates our thermal simulations, we do not have an accurate junction-to-case thermal resistance for this device. Although the UC1846-SP device uses the same package, the thermal resistance takes into account the die…

    Hi Jenny, As far as I know, TPSM846C24 module is not specifically manufactured to withstand radiation. You may find some SEE TI products here: e2e.ti.com/.../slyt532g.pdf
