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.

Now I could reduce the resistance, however the heat dissipated would be more which I don’t want. Ok H11AA seems to work on 1mA. Yes, I see you wrote, “sense when optocoup,er is line and otherwise. Anyway what is the minimum current for H11AA? Hence I started searching for it and found one i.

Schematics you’ve tried would be nice. Also, I’d like to know exactly what you mean by “detect line voltage. Post as a guest Name. I am just trying to get the state of an electrical device, i. Sign up using Email and Password.

Due to all these factors, someone suggested me to find another opto which works at very low current. This opto-coupler will work fine at 1 mA AC. To my question areyou able to help me with SFHA-3? Hence we cannot accommodate more heat.

While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V. Take a look at an IL if you want to know what the line voltage is as 8144 current in the two output diodes is well matched.

Also H11AA seems to be obsolete.

I am also not able to use a x-capacitor or use a transformer due to size constraints. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

As long dataheet there is AC input Vout is at close to zero volts. The output will be a HZ ripple on 60 HZ power lines. I changed R1 to K which greatly reduces heat. I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0.

It shows operation at uA and 1mA. Sign up or log in Sign up using Google. Home Questions Tags Users Unanswered. Digikey is showing H11AA as obsolete.

Or do you just want to know that AC of at least a certain rms voltage is there? What is the minimum current required for this opto.

Just saying “MCU” doesn’t tell me what it is for. Fairchild still makes it. Email Required, but never shown.

This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat. H11AA is supplied by Digikey and Mouser. Sparky 11k 2 15 Sorry for the long story, I am still learning. Sign up using Facebook.
