As long as there is AC input Vout is at close to zero volts. To my question areyou able to help me with SFHA-3? Sorry for the long datashheet, I am still learning.

The output will be a HZ ripple on 60 HZ power lines. H11AA is supplied by Digikey and Mouser. Digikey is showing H11AA as obsolete. Sign up or log in Sign up using Google. Post as a guest Name. What is the minimum current required darasheet this opto. Fairchild still makes it. Anyway what is the minimum current for H11AA?

Sparky 11k 2 15 Due to all these factors, someone suggested me to find another opto which works at very low current. This would create lot of potocoupler compared to the one with K and as mentioned in my query we cannot accommodate more heat.

Hence I started searching for it and found one i. Home Questions Tags Users Unanswered. It shows operation at uA and 1mA.

Hence we cannot accommodate more heat. While testing my circuit at various input voltages I found that the opto 84 start giving fluctuating output when my voltage is V.

Also H11AA seems to be obsolete. Sign up using Facebook. I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0.
