HOME / Optocoupler with parallel Zener diode - Budowa Silesia Photonics
Optocoupler is an electronic component that transfers electrical signals between two isolated circuits by using light. It is common to find commercial products consist of an infrared emitting diode, optically
Hi everyone, Ive been looking at a manual for an old PRO-LOG card which has optoisolated inputs for interfacing with a TTL based system. Across each
Low-voltage Zener Diodes tend to have a significant amount of leakage current while the voltage is below or near the Zener voltage. This causes the opto-coupler to start turning on too early.
The optocoupler could be connected across both output supplies, and the two zener diodes doubled up in series, to regulate the total output voltage of 82 volts.
Hi everyone, Ive been looking at a manual for an old PRO-LOG card which has optoisolated inputs for interfacing with a TTL based system. Across each optocoupler is a reverse
Resistor parallel to optocoupler LED in Zener-stabilized circuit (3 Solutions!!) -
In this post, you will learn the concept of the connections of the Zener diodes in series and parallel. I explain the total voltage and watt power calculation in different combinations of Zener
I''ve placed a parallel resistance to raise the input diode threshold to remove some input noise and a Zener diode at 28V Vz to protect against over voltage. Zener diodes, just like LEDs will
Hey, I''m working on a small Arduino project that basically turns on two relays when a few 12v triggers are active. Since a nano will probably fry instantly if the 12v trigger wire is directly
The individual optocouplers could control different functions or be paralleled to become polarity independent. Note that in this connection, the LED''s protect each other in reverse bias.
To find a pin-to-pin alternative to the optocouplers in your design, search TI''s cross reference tool. For more opto-emulators, browse through the online parametric tool.
