* PPORT PINT and can be neglected. PPORT may become significant if the device is configured to drive Darlington bases or sink LED loads. An approximate relationship between PD and TJ (if PPORT is neglected) is : PD = K + (TJ + 273C) (2) Solving equations 1 and 2 for K gives : K = PD. (TA + 273C) + JA. PEF6805R2 Distributors
