Opto Isolator Ic

An opto isolator is an electronic component that transfers electrical signals between two isolated circuits by using light. Optoisolator ic allows two circuits to exchange signals yet remain electrically isolated. Vishay semiconductor opto division optoisolator 3 75kv trans 4 sop 54 000 immediate available.

Opto isolator ic.

The phototransistor acts as an output device while the led acts as an input device. A common type of opto isolator consists of an led and a phototransistor in the same opaque package. Commercially available opto isolators withstand input to output voltages up to 10 kv and voltage transients with speeds up to 25 kv μs. Optocoupler has also some different names such as opto isolator optical isolator photocoupler etc.

Let s take the function of optoisolator ic part of error signal feedback that were found in switch mode power supplies as an example. The figure 14 circuit s optocoupler phototransistor is wired between the input and ground of the driven right hand ttl ic because a ttl input needs to be pulled down to below 800mv at 1 6ma to ensure correct logic 0 operation. Cmos ic outputs can source or sink currents up to several ma with equal ease. The ir diode is connected between terminals 1 and 2 the phototransistor is connected at terminals 4 5 and 6 the internal setup of two components can be seen below.

One is infrared diode and another of infrared phototransistor. Let s see what inside an optocoupler ic. 4n25 optocoupler ic has two components integrated in it. Other types of source sensor combinations include.

Ic 4n35 ic pc817 and other 4nxx series ics are examples of optocoupler ics. Opto isolators prevent high voltages from affecting the system receiving the signal.
