Optoisolators are electrical components used to transfer signals from one electronics circuit to another while also isolating the two circuits from one another. Commonly used in audio, industrial, automotive, and medical applications, the EL815(S1)(TD)-V is a type of photovoltaic optoisolator with a transistor output. This device operates by sending an electrical current through an LED, which in turn emits light. This light is sent to a photo-detector of the optoisolator which, in turn, could activate various relays, solenoids, or other electrical components. These input/output transmissions can be conducted while suffering minimal noise interference.

The EL815(S1)(TD)-V optoisolator provides excellent insulation between its input/output channels while providing reliable electrical signal transmission from one circuit to the next. It can provide a maximum isolation voltage of 2500V RMS and a maximum current transfer ratio of 100mA, allowing it to conduct a broad variety of applications requiring various levels of power. Its compact design (SOP package) allows for easier installation into applications with limited space. The EL815(S1)(TD)-V is also RoHS Compliant and is intended for use in a wide range of industrial applications, including automotive, medical, audio, and other applications.

The device can be operated in either direct or inverse mode, with the output active state being high or low in each mode. Direct mode has the output active state being high when the input device is enabled. Inverse mode has the output active state being low when the input device is enabled. Additionally, the EL815(S1)(TD)-V features transient protection, which helps protect the device from the effects of voltage surges and transient voltages, ensuring a secure and reliable connection.

The EL815(S1)(TD)-V optoisolator application field includes a wide range of audio, automotive, industrial, and medical applications such as sensors, control systems, power supplies, driver stages, and more. In the audio realm, the device is commonly used in professional audio systems for its ability to transmit signals and provide excellent noise immunity. In automotive applications, this device is an ideal signal transfer choice as it requires minimal power, small space, and offers reliable isolation.

The working principle of the EL815(S1)(TD)-V optoisolator involves utilizing a light-emitting diode (LED) as an input device on one side, and a photo-detector on the other side. Input devices on the LED side trigger an electrical current, which powers the LED and sends light through the application. When the LED is powered, the light is received by the photo-detector, which triggers the output side of the device. This output device can be various components, such as relays, solenoids, and more, depending on the application.

The EL815(S1)(TD)-V offers an excellent level of signal transmission, providing reliable isolation between its input and output. It can be used in a wide variety of applications, including audio systems, automotive systems, industrial systems, power supplies, and control systems. While offering a compact design, this device is easily installable and can provide up to 100mA of current and 2500V RMS of optical isolation. Its transient protection functionality helps protect against electrical surges, making the EL815(S1)(TD)-V a reliable and secure signal transfer device.
