Optoisolators - Transistor, Photovoltaic Output provide electrical isolation between an input signal and an output signal, in order to separate two circuits from each other. The LTV-8141 is a photovoltaic output isolator designed for use in a variety of applications. This isolator is commonly used for isolating logic circuits, isolating power lines, and providing protection from transients and ESD.

The LTV-8141 is a hybrid semiconductor device, comprising a hybrid photovoltaic IC full-wave rectifier and output transistor array. It has an integrated gate array composed of two transistors, one of which is a photo-diode, and a zener diode. The transformer serves as the electrical isolation component between the input and output section.

The LTV-8141 provides fast response time and high isolation voltage, which makes it ideal for harsh environment such as in industrial and military applications. The insulated single power pin provides good EMC performance while the low input current and current transfer ratio ensures efficient and reliable power transfer. In addition, the LED opto-isolation provides noise protection and double output voltage to minimize external components.

The operating principle of the LTV-8141 is based on the use of an LED as an optical device which senses changes in the input voltage. This voltage changes induce a corresponding current variation in the LED which is in turn converted into an output voltage. The output voltage is proportional to the input voltage, and is stored in the zener diode. The photo-diode and transformer together provide electrical insulation between the input and output section, thus providing complete isolation between the two circuits.

The LTV-8141 is available in several packages including SOP, SOIC and TSSOP. It offers an excellent performance-price ratio and is highly reliable, making it the ideal choice for applications requiring efficient isolation. It is also suitable for a wide range of applications such as signal processing, communication, power supply control and industrial automation.

In summary, the LTV-8141 is a compact and economical photovoltaic output isolator designed for a variety of applications. Its operating principle is based on the use of an LED and transformer to achieve electrical insulation, while its insulated single power pin provides good EMC performance. The device is available in several packages and is suitable for a wide range of applications. It offers an excellent performance-price ratio and is highly reliable, making it a cost-effective solution for many applications.
