814 OPTOCOUPLER DATASHEET PDF
Optocoupler, Phototransistor Output, AC input. Features The KP/ KP/ KP consist of a phototransis- tor optically coupled to 2. The FOD consists of two gallium arsenide infrared As per DIN EN/IEC , this optocoupler is suitable for “safe electrical insulation” only .. “ Typical” parameters which may be provided in ON Semiconductor data sheets and/or.

This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat. As long as ooptocoupler is AC input Vout is at close to zero volts. I am just trying to get the state of an electrical device, i.

PC SMD, AC (transistor output) – elpro Elektronik
Now I could reduce the resistance, however the heat dissipated would be more which I don’t want. Hence we cannot accommodate more heat.
The output will be a HZ ripple on 60 HZ power lines. Also H11AA seems to be dtasheet. Sign up or log in Sign up using Google.

H11AA is supplied by Digikey and Mouser. WhatRoughBeast yes I understand that the heat dissipated is less, however my circuit sits inside a closed container and Satasheet have many of these multiple opto and resistors. Post as a guest Name. Optocouplef calculated the voltage and found that for V AC and a series resistance of K, the current is just 0. Sparky 11k 2 15 Yes, I see you wrote, “sense when there is line and otherwise.
To my question areyou able to help me with SFHA-3? Digikey is showing H11AA as obsolete. I changed R1 to K which greatly reduces heat.

Ok H11AA seems to work on 1mA. 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. Email Required, but never shown.
Schematics you’ve tried would be nice. Anyway what is the minimum current for H11AA?
Hence I started searching for it and found one i. Fairchild still makes it. Due to all these factors, someone suggested me to find another opto which works at very low current.
While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V.
This opto-coupler will work fine datahseet 1 mA AC.
Just saying “MCU” doesn’t tell me what it is for. Home Questions Tags Users Unanswered. I am also 841 able to use a x-capacitor or use a transformer due to size constraints.
