L.S.
I'm a noob on temperature coefficents of diodes.
The datasheet of LM134/234/334 shows a way of minimizing the tempco by adding a diode in series, the tempco's cancel each other out, at least for most parts.
But the 1N457 is a conventional type, and I cannot even find a single SMD diode where the tempco is specified in the dataheet.
Can anyone help me out? Does a drop in replacement of the 1N457 exist?
Maybe we can persuade Texas Instruments to make an addendum to the datasheet of this ancient (National instruments) part that mentiones an SMD diode?
Thanks in advance,
Loek
