To my question areyou able to help me with SFHA-3? This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat.

Yes, I see you wrote, “sense when there is line and otherwise. Or do you just want to know that AC of at least a certain rms voltage is there? I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0. Sign up or log in Sign up using Google.

Sorry for the long story, I am still learning. Fairchild still makes it. Home Datasheett Tags Users Unanswered. As long as there is AC input Vout is at close to zero volts.

Now I could reduce the resistance, however the heat dissipated would be more which I don’t want. Sparky 11k 2 15 Due to all these factors, someone suggested me to find another opto which works at very low current. Take a look at an IL if you want to know what the line voltage is as the current in the two output diodes is well matched.

Ok H11AA seems to work on 1mA. Anyway what is the minimum current for H11AA? While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V. Also, I’d like to know exactly what you mean by “detect line voltage.

Hence I started searching for it and found one i.

It shows operation at uA and 1mA. Email Required, but never shown. This opto-coupler will work fine at 1 mA AC. I am just trying to get the state of an electrical device, i.

The output will be a HZ ripple on 60 HZ power lines.

Schematics you’ve tried would be nice. I am also not able ooptocoupler use a x-capacitor or use a transformer due to size constraints. 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. What is the minimum current required for this opto.
