HI,
I would like to know how my fancy transistor circuit works over temperature.
Most transistor data sheets provide three temperature ranges for Vbe, Ic, and Hfe.
How does one interpolate these paramters at different temperatures?
For Hfe would one just do a linear interpolation?
Hfe is impacted by temperature and Ic.
Is there a relationship that can be used?
For Vbe would one do a linear interpolation to find the new vbe at some temperature keeping Ic at a constant current then find what the new Vbe would be at a different Ic based on the new Vbe from from the new temperature?
Vbe is impacted by temperature and Ic.
Ic=is*e^(Vbe/vt)
Im just trying to understand how I can use the data sheet to get other values Hfe, Vbe, and Ic at different temperatures so I can model my circuits more accurately.
If you have any good reading to point me to that would be most welcome.
or maybe I am making this more complicated than need be???
Thank you
