ISOCOM ISP621-4X 4-Channel Optocoupler, DIP-16, 5.3kV, 50% CTR

The ISOCOM ISP621-4X is a high-density, 4-channel phototransistor optocoupler designed to provide reliable electrical isolation and signal transmission. It integrates an infrared LED optically coupled to an NPN silicon phototransistor in each channel, ensuring precise control and protection for sensitive circuits. This component is engineered for performance-critical applications where signal integrity and electrical isolation are paramount.

Featuring a high current transfer ratio (CTR) of 50% minimum, it ensures efficient signal coupling and robust performance. The device also boasts a high collector-emitter voltage (BVCEO) of 55V minimum and a formidable isolation voltage of 5.3kV, making it an excellent choice for protecting low-voltage control circuits from high-voltage noise, transients, and potential differences in the system.

Key Features & Benefits

• High-Density Design: Four independent isolation channels in a single compact DIP-16 package, saving valuable board space.
