Freescale Semiconductor
Thermal
Ideality factor is defined as the deviation from the ideal diode equation:
Another useful equation is:
Where:
Ifw = Forward current
Is = Saturation current
Vd = Voltage at diode
Vf = Voltage forward biased
VH = Diode voltage while IH is flowing
VL = Diode voltage while IL is flowing
IH = Larger diode bias current
IL = Smaller diode bias current
q = Charge of electron (1.6 x 10 –19 C)
n = Ideality factor (normally 1.0)
K = Boltzman’s constant (1.38 x 10–23 Joules/K)
T = Temperature (Kelvins)
The ratio of IH to IL is usually selected to be 10:1. The above simplifies to the following:
Solving for T, the equation becomes:
Ifw = Is e
