H11AA is supplied by Digikey and Mouser. This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat.

I am also not able to use a x-capacitor or use a transformer due to size constraints. Digikey is showing H11AA as obsolete. To my question areyou able to help me with SFHA-3? Anyway what is the minimum current for H11AA?
Also, I’d like to know exactly what you mean by optpcoupler line voltage. Email Required, but never shown. Sign up or log in Sign up using Google.
Also H11AA seems to be obsolete. Opyocoupler 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.
Home Questions Tags Users Unanswered. Now I could reduce the resistance, however the heat dissipated would be more which I don’t want.

Or do you just want to know that AC of at least a certain rms voltage is there? Post as a guest Name.
Schematics you’ve tried would be nice. Sign up using Email and Password.
While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V.
Just saying “MCU” doesn’t tell me what it is for. The output will be a HZ ripple on 60 HZ power lines.
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. I changed R1 to K which greatly reduces heat. It shows operation at uA and 1mA.
Yes, I see you wrote, “sense when there is line and otherwise.
PC SMD, AC (transistor output) – elpro Elektronik
I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0. What is the minimum current required for this opto. Hence I started searching for it and found one i. I am just trying to get the state of an electrical device, i.
