1.

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

2.

Same as I

FW

 in the diode model in 

3.

Characterized across a temperature range of 50-80°C.

4.

Not 100% tested. Specified by design characterization.

5.

The ideality factor, n

Q

, represents the deviation from ideal transistor model behavior as exemplified by the 

equation for the collector current: I

C

 = I

S

 * (e

qVBE/n

Q

kT

 - 1)

Where I

S

 = saturation current, q = electronic charge, V

BE

 = voltage across the transistor based emitter 

junction (same nodes as V

D

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

6.

The series resistance, R

T

 provided in 

 can be used for more accurate readings as needed.

 Processor 5000 Series Thermal/Mechanical Design Guidelines for more 

information on how to use the Tdiode_Offset, Tdiode_Base and n

trim 

parameters for fan speed control.
