High-Isolation 6-Pin DIP Optoisolator with NPN Output

Reliable Signal Isolation with NPN Transistor Output

This 6-pin DIP optoisolator provides robust electrical isolation between input and output using an integrated NPN transistor output stage. Engineered for applications requiring safe interfacing of low-voltage logic with higher voltage or noisy systems, this optocoupler is ideal for switching, signal transmission, and protection circuits.

Key Features and Specifications

• Optoisolator Type: Phototransistor output, NPN (NTE3041 / compatible part number)
• Package: 6-pin Dual Inline Package (DIP)
• Isolation: High dielectric strength ensures protection from high-voltage transients
• Standard Output: NPN transistor enables direct driving and interfacing with TTL and logic-level circuits
• Quantity Per Package: 1

Applications

• Signal isolation between logic circuits and high-voltage or noisy environments
• Switching power supplies and AC line monitoring
• Microcontroller and PLC input/output isolation
• Relay driving with galvanic isolation
• General-purpose circuit protection and interface

Usage and Integration

To use in a circuit, connect the input side LED to the logic or control signal; when energized, the internal NPN phototransistor activates the output side. The compact 6-pin DIP form makes this optoisolator easy to integrate into standard through-hole PCBs.

For engineers and designers requiring dependable, high-isolation signal coupling, this optoisolator with NPN transistor output delivers consistent performance and reliable protection for sensitive electronic systems.
