Optocoupler EB759627624 1-channel 5 kV insulation

Optocoupler EB759627624 is a single-channel optoisolator engineered to provide galvanic isolation up to 5 kV between input and output. It transfers electrical signals through an optical barrier to protect low-voltage control circuits from high-voltage transients, ground potential differences, and interference. The device is intended for use in environments where reliable signal transmission and safety are required between separated circuit domains.

Advantages

This optocoupler offers high-voltage isolation up to 5 kV in a compact single-channel format, ensuring simple integration into control and measurement systems. Its optical coupling reduces common-mode interference and isolating the control side from power electronics improves safety and measurement accuracy. The device supports straightforward implementation in systems that require a robust, electrically non-conductive signal path.

Suitable for

• Industrial control systems and PLC interfaces
• Power electronics and inverter control circuits
• Measurement and data acquisition systems requiring galvanic isolation
• Protection of microcontroller inputs from high-voltage transients
• Signal isolation in communication lines and sensor interfaces

Key specifications

• Channel count: single-channel optoisolator
• Isolation voltage: up to 5 kV between input and output
• Signal transfer method: optical coupling (optoelectronic)
• Primary function: galvanic isolation of control and measurement signals
• Typical applications: isolation for control circuits, measurement inputs, and sensor lines

How to use

Install the optocoupler in the circuit following recommended PCB layout practices for isolation components: maintain appropriate creepage and clearance distances and separate high-voltage and low-voltage routing. Connect the input LED side to the signal source with a suitable current-limiting resistor, and connect the output phototransistor or photodiode side to the receiving circuit with appropriate pull-up or pull-down components as required by the design. Verify the polarity and operating current ranges before applying power and perform isolation testing after assembly to confirm expected withstand voltage.

Usage recommendations

Use the device where galvanic isolation is needed to protect control electronics from high-voltage domains. Ensure that PCB creepage and clearance meet your system's safety standards and consider adding transient suppression on the input or output if the environment has high electromagnetic interference or frequent voltage spikes.
