Thermal Specifications and Design Considerations
82
Datasheet
NOTES:
1.
Intel does not support or recommend operation of the thermal diode under reverse bias.
2.
Same as IFW in Table 29.
3.
Preliminary data. Will be characterized across a temperature range of 50–80 °C.
4.
Not 100% tested. Specified by design characterization.
5.
The ideality factor, nQ, represents the deviation from ideal transistor model behavior as
exemplified by the equation for the collector current:
IC = IS * (e
qVBE/nQkT –1)
Where IS = saturation current, q = electronic charge, VBE = voltage across the transistor
base emitter junction (same nodes as VD), k = Boltzmann Constant, and T = absolute
temperature (Kelvin).
6.
The series resistance, RT, provided in the Diode Model Table (Table 29) can be used for
more accurate readings as needed.
The Intel® Pentium® Dual-Core Desktop processor E2000 series does not support the
diode correction offset that exists on other Intel processors.
