The EL816-V optoisolator is a transistor, photovoltaic output device that offers exceptional isolation, ultra-low capacitance and low power consumption in a tiny, low-cost packaging. It is an ideal solution for applications where an extremely low power signal must be transmitted reliably across a galvanic isolation barrier. The EL816 series is offered in a choice of packages, including a miniature hermetic DIP-4 package, a space-saving SMD package, and a through-hole package.

The EL816-V optoisolator works on a basic principle of infrared light transmission. It is a combination of an infrared LED element and a photovoltaic element. The LED element emits infrared light when excited by an electrical signal. That light is then detected by the photosensitive element, which is a photodiode mounted inside an optically sealed cast epoxy case. The photodiode converts the light energy emitted by the LED into a power signal. This signal is then amplified and rectified so that it can be used for data transmission, or other applications.

The EL816-V optoisolator offers a high level of isolation, up to 4192Vrms, which exceeds the requirements of most isolation test standards. This makes the device suitable for a variety of industrial and consumer applications,such as medical equipment, process controllers, switchgear, and test instrumentation. The device is also designed to have a low input capacitance of less than 2.8pF, reducing the risk of noise interference and power supply fluctuations.

The EL816-V optoisolator also offers an outstanding level of reliability. The optically sealed design protects the device from damage caused by dust, moisture, vibration, and other environmental factors. The device is also designed to be resistant to ESD and other electrical factors. Additionally, the hermetic seal ensures a high level of consistency in the device’s performance over its rated life of up to 300,000 hours.

In conclusion, the EL816-V optoisolator is a versatile device that is designed for superior isolation and reliability. With its excellent performance in power conservation, coupled with its hermetic packaging, the EL816-V is an ideal choice for a wide range of industrial and consumer applications.
