Playing with Schottkey

Not to rain on your parade, but the world isn't particularly short of uncalibrated nonlinear temperature sensors.

..maybe put it in series with an LED for a 'hot enough to burn human flesh' warning?

Or global warming :-)

Not to be disagreeable, but your invaluable time calibrating it probably increased the cost to a large multiple of the cost of the raw part (15 cents?).

I wonder where we could stick them that would be sensitive enough?

Hello Jan,

This isn't strange,

The reverse current doubles each 8..10 K increase in temperature. Normally you don't notice this (as for PN junction diodes, leakage can mostly be ignored [many exceptions]), but in schottky rectifiers, low conduction loss results in high reverse current.

Jeez, next you're going to point out that using glass-encased diodes as photodetectors isn't exactly solving a pressing world problem either. :-)

Using LEDs as both a photo source and as a (rather lousy) detector to build bi-directional data links *is* cool, though.

No, but using it that way inadvertently could cause problems, like causing an H-bridge to vaporize when you take a flash photograph of the controller. ;-)

It's cool. What interesting variations are there with different wavelength/color LEDs?
