EL816(S1)(C)(TU)-V

Optoisolators are electrical components designed to provide isolation values between two or more electrical circuits. They are commonly used in industrial, aerospace, medical and automotive applications. The EL816 series of optoisolators are transistor, photovoltaic output devices. These devices are designed to provide 5000 Vrms of electrical isolation between input and output circuits.

The EL816 optoisolator is a low profile surface mount device. These optoisolators are offered in three package configurations namely, plastic molded single in-line, plastic dual in-line and metal can variety. The plastic packages and metal cans are hermetically sealed to ensure that no contaminants penetrate the device. This helps in maintaining reliable performance and durability of the device even in industrial applications. The devices offer low stand-off voltage as low as 7 V and operate over a wide temperature range from -40°C to 110°C.

The EL816 optoisolators have a LED input circuit which includes a gallium arsenide infrared LED with a dedicated phototransistor output. The LED input circuit responses to input signals such as logic signals, low frequency or high frequency analog signals depending on the application type. The isolated output signal from the phototransistor is provided with a totem pole circuit to ensure that the collector output to the base input maintains a logic high or low logic condition. The device has a dual transistor output circuit which provides a common collector output for logic high and a common emitter output for logic low. The output stage is designed to provide 500 mA DC of current which can drive direct connected TTL loads.

These optoisolators are designed to function reliably in harsh environmental conditions. They are highly resistant to shock, vibration and other environmental influences making them an ideal choice for industrial applications. The device offers fast switching speed and provides excellent data transfer rate even in high speed communication systems. The optoisolator can also be used in inverter systems, signal isolators, regulated power supplies, and transducer interfaces.

In summary, the EL816 optoisolator series are transistor, photovoltaic output optoisolators designed to provide electrical isolation between two or more circuits. The optoisolator has a LED input with a phototransistor output. It offers low stand-off voltage and operates over a wide temperature range. The device is hermetically sealed and is highly resistant to environmental influences such as shock, vibration and humidity. These optoisolators are designed to provide reliable performance in industrial applications and can be used in inverter systems, signal isolators, regulated power supplies, and transducer interfaces.
