SMS1105OC Optoelectronics

LED technology has been widely applied in the field of indication for decades. Among the various indication products, LED discrete indication, featured with its simple structure, high reliability, wide voltage range and very low power consumption, is the most popular one. Among the LED discrete indication products, SMS1105OC is one kind of eminent one.

SMS1105OC is a red LED discrete indication device. It is a 5 mm through-hole product with a 10 mm lead pitch and 2 pins, featuring with excellent visibility, low power consumption and easy installation. Its packing length is 15 mm, which is quite small and suited to be applied without extra space inside the PCB. Therefore, SMS1105OC is very suitable for indication in miniaturization applications.

SMS1105 are applied in a lot of kinds of applications, such as audio/visual equipments, operation status indication, home appliances, etc. When it’s used for operation status indication, it can be a very good choice for its high reliability and easy installation. Besides, the technology of SMT allows for the flexible assembly to the PCB, and its wide range of operating temperature, -25℃~+85℃, supports its stability and reliability. The quite low power consumption, 20~50mA, allows for a longer service life.

The working principle of SMS1105OC is quite simple. It consists of a sacrificial anode and a semiconductor material circuitry. When the negative voltage is applied, the sacrificial anode works as an emitter and the electrons are exited to fill the holes, resulting in the formation of photon currents and finally the light of LED. That is also the way for the LED to work for indication use.

In conclusion, SMS1105OC is an eminent LED discrete indication device featured with its high reliability, wide voltage range, low power consumption and miniaturization packing length. It is quite suitable to be applied in many kinds of fields like audio/visual equipments, operation status indication, home appliances, etc. And its quite simple working principle makes it easy to install and use.
