... This gives the coordinates (VCC,0) on the x axis of the output characteristics. The other extreme point is on the y-axis and can be calculated by making VCE = 0 in the equation VCE = VCC – ICRC which gives IC( max) = VCC / RC thus giving the coordinates of the point as (0, VCC / RC). The two extreme ...

Opto-isolator



In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 10 kV/μs.A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
