Optoisolators are a type of semiconductor used to transfer electrical and optical signals between two isolated circuits. EL817(S1)(D)(TA)-G is a type of optoisolator with a transistor, photovoltaic output. This particular optoisolator is a 4-pin device—the four pins being the anode, cathode, emitter, and collector. Its pin out is A C E B.

The EL817(S1)(D)(TA)-G optoisolator works by transferring a signal from its anode to the emitter pin given a voltage between 9 and 16V, via a high-speed LED. Once the LED is activated, the electron flow from the emitter to the collector is blocked and a signal is produced on the collector side. This isolated signal can transmit the original signal with minimal loss.

The EL817(S1)(D)(TA)-G is widely used in industries such as automotive, medical, power, consumer electronics, and industrial automation. It is often used to transfer information across long distances, provide electrical isolation, or control circuits that are in different locations. This optoisolator helps protect sensitive circuits from EMC noise, reducing the risk of electrostatic discharge.

In terms of versatility, the EL817(S1)(D)(TA)-G optoisolator is particularly useful for its low dark current and low speed. It has a very low threshold current of 0.1 mA and a maximum collector current of 30 mA. It can be operated from -40 to +105 degrees celsius. Thecollector-emitter current is 1 mA at 10mA of emitter current.

The EL817(S1)(D)(TA)-G is designed for low to medium voltagelogic isolation applications or control circuit isolation applications. It is also suitable for applications that require high speed switching and logic level isolation. This optoisolator has excellent speed performance, low input and output current noise, and low power requirements.

Finally, the EL817(S1)(D)(TA)-G has a p-channel MOSFET buffer which helps provide a high speed and an excellent output skew. Its maximum switching speed is 10MHz and its maximum propagation delay is 10ns. With its easy installation, long term reliability, and low power requirements, this optoisolator is a great choice for a variety of applications.
