Optocoupler, Darlington Output, 4 Channel, DIP 16-Pin, 5.3 kV
ISOCOM ISP845X 4-channel optocoupler with Darlington output. 5.3kV isolation, 600% CTR, 16-pin DIP. For industrial control & signal processing.
The ISOCOM ISP845X is a high-density, four-channel photodarlington optocoupler, providing robust electrical isolation and signal transfer in a compact dual-inline package (DIP). This device integrates an infrared light-emitting diode (LED) optically coupled to a high-gain NPN silicon photodarlington transistor in each of its four channels.
Engineered for reliability, it offers a high current transfer ratio (CTR) of 600% minimum, ensuring efficient signal coupling even at low input currents. Its high isolation voltage rating of 5.3 kV provides excellent protection against voltage transients and ground loop noise, making circuits safer and more stable.
The ISP845X is housed in a standard 16-pin DIP, facilitating easy prototyping and integration onto printed circuit boards (PCBs). Its typical applications span across diverse fields where electrical isolation is critical. It is commonly used for interfacing low-voltage control signals with higher-voltage or noisy power circuits, system monitoring, and signal conditioning.
With a maximum forward current of 50 mA per channel and a collector-emitter voltage rating of 35 V, this optocoupler is suitable for a wide range of switching and linear analogue signal isolation tasks. Its compact dimensions and industry-standard footprint make it a versatile choice for modern electronic design.
