EL3H7(K)(EB)-VG

Optoisolators are devices used to provide electrical isolation between two sections of a circuit while maintaining a data connection. Many of them employ a photovoltaic cell or an LED and a phototransistor to achieve this purpose. The EL3H7 (K)(EB)-VG is an example of this type of device, and it is commonly found in industrial or automotive applications.

The EL3H7 (K)(EB)-VG is a transistor output optoisolator circuit with a wide variety of functions and applications. It has a current transfer ratio of 100 or more, an isolation voltage rating of 6300 Vrms, and an operating temperature range of 0 to 70℃. This optoisolator is popular among engineers because it offers a combination of robust features and high performance levels. It can be used for a variety of industrial and automotive applications such as electrical noise detection, motor speed control, automotive power window systems, and even temperature sensors.

The working principle of the EL3H7 (K)(EB)-VG consists of a highly sensitive phototransistor output stage that is triggered by a TTL compatible LED input. When the LED input is trigged, the output from the phototransistor moves from its low state into a high state. This change in the voltage state is then used to trigger another circuit. This type of optoisolator can be used to detect low level signals, such as electrical noise, and can be used to control circuit operations, such as motor speed control. It is also well suited to controlling electronic power window systems found in modern cars.

The EL3H7 (K)(EB)-VG is a highly sought-after optoisolator in automotive and industrial applications. It is reliable, robust, and has been proven to be capable of transmitting signals over long distances. It is ideal for applications such as electrical noise detection, motor speed control, automotive power window systems, and temperature sensors.
