TECHNICAL DATA
NOTES:
1 This is an approximate value, neglecting PI/O.
2. For most applications PI/O PINT and can be neglected.
3. K is a constant pertaining to the device. Solve for K with a known TA and a measured PD (at equilibrium. Use
this value of K to solve for PD and TJ iteratively for any value of TA
