ISOCOM 4N32 Optocoupler, Darlington, 1-Channel, DIP-6, 80mA, 5.3kV

The ISOCOM 4N32 is a high-performance, optically coupled isolator designed to provide electrical isolation in demanding electronic circuits. It integrates an infrared LED and an NPN silicon photodarlington in a single, compact package, making it a key component for ensuring safety and signal integrity.

A defining feature is its exceptionally high isolation voltage of 5.3kV, which effectively protects sensitive circuitry from high-voltage transients and ground loop issues. This robust isolation is critical for maintaining reliable operation in noisy industrial and commercial environments. The component also boasts a high current transfer ratio (CTR), ensuring efficient signal coupling between the input and output sections.

Its Darlington output configuration provides significant current gain, making it suitable for directly driving small loads or interfacing with other control elements. Housed in a standard 6-pin DIP (Dual In-line Package), it is easy to integrate into through-hole PCB designs, facilitating prototyping and production.

Typical Applications

• Computers & Peripherals: For signal isolation in interfaces and communication ports.
