The datasheet says maximum input current is 60mA, so I thought that if I drove the diodes with 20mA peak, that would seem "safe". However, I wanted to use the VAC v peak as an input, so with 0.
So I decided to base the resistance on a dissipation of 0. Max instantaneous current is 1. I have looked at a number of application circuits that have equal-value resistors on the live and neutral wires. Is there any good sense in that, apart from giving more dissipation from 2 resistors than you can get from one? Timebase is at 2mS per division. When I tried touching another 10k across it to momentarily give 5k, the pulse on the scope got wider still, so I put the 22K resistor in, which improved things marginally.
Should I be driving the diodes harder? Is there any way of getting a pulse that says "This is the moment of zero crossing", rather than "The zero crossing happens round about now"?
The pulse will be used to trigger the interrupt pin of a micro-controller, so I could put 5mS compensation into that, but it would be so much more elegant to have a zero-crossing detector that detects zero crossings.
