Optocoupler Device CTR and Circuit CTR Explained

When you already heard about Optocoupler devices, you may be heard also about CTR. CTR stands for current transfer ratio. In bipolar junction transistor this is the so called current gain or simply beta. It is the ratio of the collector to forward current of an Optocoupler. In circuit design involving optocoupler, you may be dealing with the device CTR

Factors Affecting Current Transfer Ratio of Optocoupler

Current transfer ratio is comparable to BJT’s HFE or beta (β). This is the ratio of the optocoupler’s collector current to the forward current. Current transfer ratio is popular by its abbreviation CTR. CTR is simply the measure of the optocoupler’s transfer efficiency. If we recall the basics, optocoupler is a semiconductor device with a light source and a detector.

Opto Coupler CTR Explanation

Opto coupler CTR explanation is not well elaborated by other authors and before I was also having hard time of understanding what is it. Current transfer ratio or commonly known as CTR is the ratio of the collector current to the forward current of an optocoupler. It is synonymous to a current gain of a bipolar junction transistor. If this is the first
