Fairchild still makes it. Sign up using Facebook. To my question areyou able to help me with SFHA-3?
I changed R1 to K which greatly reduces heat. Sign up using Email and Password. As long as there is AC input Vout is at close to zero volts. This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat. Just optocouupler “MCU” doesn’t tell me what it is for. Email Required, but never shown. Ok H11AA seems to work on 1mA.

The output will be a HZ ripple on 60 HZ power lines. Or do you just want to know that AC of at least a certain rms voltage is there? Post as a guest Name. I am just trying to get the state of an electrical device, i. Sorry for the long story, I am still learning. Hence I started searching for it and found one i. Home Questions Tags Users Unanswered.
Yes, I see you wrote, “sense when there is line and otherwise. Now I could reduce the resistance, however the heat dissipated would be more which I don’t want. Sparky 11k 2 15 It shows operation at uA and 1mA. Anyway what is the minimum current for H11AA?

Also H11AA seems to be obsolete. I optcooupler the voltage and found that for V AC and a series resistance of K, the current is just 0. Also, I’d like to know exactly what you mean by “detect line voltage. Hence we cannot accommodate more heat.
I am also not able to use a x-capacitor or use a transformer due to size constraints.
