If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3)
Human body model, 100pF discharged through a 1.5k
Ω resistor.
(4)
Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then
discharged directly into the IC with no external series resistor (resistance of discharge path must be under 50
).

The given
θJA and θJC are for an LM4855 mounted on a demonstration board with a 4in
2 area of 1oz printed circuit board copper ground
plane.
