Optoisolators - Transistor, Photovoltaic Output

The FODB102 is a photovoltaic output opto-isolator. It combines a silicon light sensitive switch and a transfer transistor in a single package. The light sensitive switch consists of a silicon phototransistor optically coupled to an infrared LED. When the LED is illuminated, the photo-transistor is activated, allowing the transistor to conduct electricity between the LED and photo-transistor.

This type of opto-isolator is especially useful when there is a need to isolates two circuits from each other for electrical safety reasons. Because the LED and photo-transistor are optically coupled, there is no electrical connection between the two circuits, allowing one side of the circuit to be electrically isolated from the other. This eliminates the possibility of electrical shock or other electrical interference between the two circuits.

The FODB102 is also suitable for use in data transmission applications. The opto-isolator transfers the data across an optically isolated interface, allowing for a high level of electrical isolation. This type of opto-isolator can be used to transmit data between various components, such as a microcontroller and a sensor. It is also suitable for transmitting data across buses, such as CAN or I2C.

The FODB102 opto-isolator has a response time of 1.5µs and a minimum isolation voltage of 1000Vrms. The maximum collector emitter voltage is 45V and the maximum collector current is 100mA. The lifetime for LED failure is 100,000 hours (or roughly 11 years of continuous operation). In terms of EMC, the FODB102 meets the standards for both ESD and RFI/EMI emissions.

The FODB102 opto-isolator is a suitable component for applications such as electrical protection, data transmission, and isolation in communication systems. Its fast switching time and high isolation voltage make it suitable for a wide variety of applications. The opto-isolator also offers excellent electrical and EMC performance, making it a reliable and cost effective option for many applications.
