Note 4:
Human body model, 100 pF discharged through a 1.5 k
resistor. Machine model, 200 pF discharged directly into each pin. Charged device model (CDM)
simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated assembler) then rapidly being discharged.
Note 5:
Reflow temperature profiles are different for lead-free and non lead-free packages.
Note 6:
The maximum power dissipation must be de-rated at elevated temperatures and is dictated by T
,
θ
and the ambient temperature, T
A
. The maximum
allowable power dissipation at any temperature is P
D MAX
= (T

Note 7:
See the URL "http://www.national.com/packaging/" for other recommendations and methods of soldering surface mount devices.
Note 8:
At the time of first pubication of this specification (Jan 2006), this specification applies to either Pentium or Xeon Processors on 90nm or 65nm process when
TruTherm is selected. When TruTherm is deselected this specification applies to an MMBT3904. This specification does include the error caused by the variability
of the diode ideality and series resistance parameters.
Note 9:
Typical parameters are at T
J
= T
A
= 25 C and represent most likely parametric norm.
