814 OPTOCOUPLER DATASHEET PDF

Ok H11AA seems to work on 1mA. Sign up using Facebook. This opto-coupler will work fine at 1 mA AC. 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.

Sorry for the long story, I am still learning. This opto-coupler will work fine at 1 mA AC. As long as there is AC input Vout is at close to zero volts. Ok H11AA seems to work on 1mA. I am just trying to datawheet the state of an electrical device, i. Hence I started searching for it and found one i. I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0.

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. To my question areyou able to help me with SFHA-3? Sparky 11k 2 15 It shows operation at uA and 1mA. I am also not able to use a x-capacitor or use datsheet transformer due to size constraints.

Or do you just want to know that AC of at least a certain rms voltage is there? Anyway what is the minimum current for H11AA? Sign up or log in Sign up using Google. Email Required, but never shown.

Fairchild still makes it.

Sign up using Facebook. Due to all these factors, someone suggested me to find another opto which works at very low current.

Home Questions Tags Users Unanswered. While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V. Hence we cannot accommodate more heat. This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat. 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. H11AA is supplied by Digikey and Mouser.

The output will be a HZ ripple on 60 HZ power lines. Post as a guest Name. What is the minimum current required for this opto. Also Datashret seems to be obsolete. Related Articles
