Optoisolator with NPN Darlington Output – 6-Pin DIP

High-Isolation NPN Optoisolator for Demanding Applications

This optoisolator features a gallium arsenide infrared emitting diode directly coupled to an NPN Darlington transistor output in a compact 6-pin DIP package. Designed for applications that require secure isolation between input and output, this optoisolator provides robust electrical separation and reliable signal transfer, making it an ideal choice for interfacing high-voltage circuits with logic-level controls.

Key Features and Technical Information

• Transistor Output: NPN Darlington for enhanced current gain and higher sensitivity.
• Package: 6-pin dual in-line (DIP) for easy PCB integration.
• SKU: NTE3042
• Quantity per Package: 1

Applications

• Microprocessor input isolation
• Switching power supplies
• Signal coupling of logic-level outputs to high-voltage loads
• Industrial controls and automation

Usage Instructions

To use, connect the input (diode side) to your signal source with appropriate current limiting resistor. The output (pins connected to the NPN Darlington transistor) interfaces to the logic or load circuit to achieve galvanic isolation. Ensure correct orientation for 6-pin DIP footprint during PCB assembly.
