Optoisolator Transistor TLP521-2XGB Output 5300Vrms

As an electronic accessory with a very wide range of applications, optocouplers are usually referred to as "optocouplers" by engineers, and some people call them opto-isolators. The main work of the optocoupler in the circuit system is to transmit electrical signals with light as a medium. Since light is required as a medium for transmitting electrical signals, the optocoupler usually chooses infrared light emitting diode LED and photosensitive semiconductor in its structural design. The tubes are jointly enclosed in a tube shell. Under this premise, the light emitter emits light when an electrical signal is applied to the input terminal, and the infrared light emitting diode LED generates a photocurrent after receiving the light, which flows out from the output terminal, thereby realizing signal conversion.

Optoisolator Triac MOC3032M Output 4170Vrms

In the process of use, the optocoupler has many advantages. The main performance advantage is that it can realize one-way transmission of signals. In the optocoupler, the input and output ends can be electrically isolated in a full sense, and have relatively strong The anti-jamming ability and high transmission efficiency. At present, in the design and development of monolithic switching power supplies, optocouplers have been widely used and recognized. The optocoupler feedback circuit composed of optocouplers can change the duty cycle by adjusting the control terminal current to achieve precision and stability Pressure.
