I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0. Now I could reduce the resistance, however the heat dissipated would be more which I don’t want. I am also not able to use a x-capacitor or use a transformer due to size constraints. Due to all these factors, someone suggested me to find another opto which works at very low current. Hence I started searching for it and found one i.
The output will be a HZ ripple opgocoupler 60 HZ power lines.

Sorry for the long story, I am still learning. Schematics you’ve tried would be dxtasheet. Also, I’d like to know exactly what you mean by “detect line voltage. Just saying “MCU” doesn’t tell me what it is for. Yes, I see you wrote, “sense when there is line and otherwise. Take a look at an IL if you want to know what the optocupler voltage is as the current in the two output diodes is well matched.
Or do you just want to know that AC of at least a certain rms voltage is there? I am just trying to get the state of an electrical device, i.
WhatRoughBeast yes I understand that the heat dissipated is less, however my circuit sits inside a closed container and I have many of these multiple opto and resistors. Hence we cannot optocokpler more heat.
It shows operation at uA and 1mA. Sparky 11k 2 15 This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat. I changed R1 to K which greatly reduces heat. This opto-coupler will work fine at 1 mA AC. Ok H11AA opptocoupler to work on 1mA.

What is the minimum current required for this opto. Also H11AA seems to be obsolete.
H11AA is supplied by Digikey and Mouser. Fairchild still makes it.

Digikey is showing H11AA as obsolete. Anyway what is the minimum current for H11AA? To my question areyou able to help me with SFHA-3? Sign up or log in Sign up using Google.
