Anyway what is the minimum current for H11AA? It shows operation at uA and 1mA.

Now I could reduce the resistance, however the heat dissipated would be more which I don’t want.

This opto-coupler will work fine at 1 mA AC. Just saying “MCU” doesn’t tell me what it is for.

Or do you just want to know that AC of at least a certain optocuopler voltage is there? Yes, I see you wrote, “sense when there is line and otherwise.

While testing my circuit at optocouplee input voltages I found that the opto will start giving fluctuating output when my voltage is V. I am also not able to use a x-capacitor or use a transformer due to size constraints.

I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0.

Ok H11AA seems to work on 1mA. 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. Sorry for the long story, I am still learning.

H11AA is supplied by Digikey and Mouser. What is the minimum current required for this opto. Sign up using Facebook. Digikey is showing H11AA as obsolete.

Schematics you’ve tried would be nice. Post as a guest Name.

Due to all these factors, someone suggested me to find another optocoupper which works at very low current. Hence I started searching for it and found one i. The output will be a HZ ripple on 60 HZ power lines. Sign up using Email and Password. Sparky 11k 2 15 Email Required, but never shown.

As long as there is AC input Vout is at close to zero volts. Fairchild still makes it. Also, I’d like to know exactly what you mean by “detect line voltage.
