Optoisolators are used for amplifying, converting, and transferring digital and analog signals. FODM121ER1V is one of types of optoisolators, characterized by its transistor output and photovoltaic input. It is a single channel, high-speed optoisolator. It has high reliability and is widely used in various applications.
FODM121ER1V Application Field
FODM121ER1V is widely used in industrial automation, automotive electronics, medical electronic products, measurement and control equipment, communication equipment, industrial lighting equipment, power supplies, sensors equipment, and optical products, etc. It can be used for data isolation, drive short circuit protection, current loop drive, line regulation, voltage regulation, analog data transfer and other occasions.
FODM121ER1V Working Principle
FODM121ER1V consists of an infrared emitting diode and a NPN-type silicon phototransistor output. During the working process, the infrared light is emitted by the LED which will be detected by the NPN-type phototransistor output. The photocurrent generated by the phototransistor output will activate the phototransistor to output a signal at the collector.
When the phototransistor receives enough illumination, it starts to conduct and the voltage at the emitter is close to 0 volts. The voltage of the collector is close to the voltage of the positive power supply of the device and the communication signal from the signal device is transferred to the load through the transistor.
When the LED does not receive any illumination, the phototransistor does not conduct and the voltage at the emitter is close to the supply voltage. That means the output signal can be controlled by the input illumination level.
FODM121ER1V is designed with enough optical coupling isolation in the circuit to ensure that the output electrical voltage signal and power supply do not affect each other. The most notable feature of the FODM121ER1V is its high-speed response speed. It features a switching speed that is less than 8 microseconds, which means it can handle a large amount of data transfer and it additionally provides anti-interference protection of up to 4 kV/ µs.
Conclusion
FODM121ER1V offers a wide range of applications and high-speed response times and anti-interference protections that make it a well-suited choice for technicians who are looking to optoisolate their circuit designs. In addition, it is designed with sufficient isolation to ensure the output electrical voltage signal and power supply is kept separate.
