Datasheet 59

Pentium

III Processor for the PGA370 Socket at 500 MHz to 1.10 GHz

NOTES:

1. Intel does not support or recommend operation of the thermal diode under reverse bias.

2. Characterized at 100 ° C with a forward bias current of 5 µA–300 µA.

3. The ideality factor, n, represents the deviation from ideal diode behavior as exemplified by the diode

equation:

=Is(e^ ((Vd*q)/(nkT)) - 1), where Is = saturation current, q = electronic charge, Vd = voltage across the

diode, k = Boltzmann Constant, and T = absolute temperature (Kelvin).

4. Not 100% tested. Specified by design characterization.
