ISOCOM ISP814XSM Optocoupler, Transistor Output, 1 Channel, SMD DIP, 4 Pins, 50

The ISOCOM ISP814XSM is a high-performance, single-channel optocoupler designed for reliable signal isolation in demanding electronic applications. Featuring a transistor output, this 4-pin device utilises an optically coupled isolator consisting of two infrared light-emitting diodes (LEDs) connected in inverse parallel and an NPN silicon phototransistor. This advanced design ensures robust signal transmission between circuits of different potentials and impedances, providing essential protection against voltage spikes and noise.

A key benefit of this optocoupler is its high isolation voltage rating of 5.3kVrms (7.5kV peak), offering superior protection for sensitive components. The AC or polarity-insensitive input simplifies circuit design by allowing flexible connection without concern for input polarity. With a forward current (If) of ±50mA and a total power dissipation of 200mW, it is built to handle a wide range of industrial signal levels.

Applications

This optocoupler is ideally suited for isolating digital or analogue signals in various systems. Its high-density surface-mount DIP package makes it perfect for space-constrained printed circuit board (PCB) designs. Key application areas include:

• Industrial system controllers and programmable logic controllers (PLCs)
• Signal processing and data acquisition systems
• Communications and networking equipment
• Computer peripherals and interface modules
• Power supply feedback circuits and motor drives
