CNY17-4M

Transistor, Photovoltaic Output Optoisolators Overview

The Lite-On CNY17-4M is a single-channel transistor output optocoupler housed in a 6-pin DIP package. It features an HCEV phototransistor with a minimum current transfer ratio of 160% at IF=10mA and VCE=5V. The device provides high isolation voltage of 5,000Vrms and supports a maximum collector-emitter voltage of 70V. Operating temperatures range from -55°C to 100°C, with typical response times around 5µs.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High input-output isolation voltage capability for safety-critical applications
• Access to the phototransistor base terminal via the 6-pin DIP configuration
• High collector-emitter voltage rating suitable for various switching loads

Transistor, Photovoltaic Output Optoisolators Applications

• General-purpose signal isolation in industrial control systems
• Microprocessor interface circuits requiring galvanic separation
• Solid-state relay driver stages

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix 'M' corresponds to the required tape-and-reel or tube packaging format as defined by Lite-On. Confirm that the HCEV variant meets the necessary insulation coordination standards for your target market, such as UL or CSA recognition requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a base-accessible phototransistor is required for improved switching speed or linearity compared to standard variants. Ensure the 160% minimum CTR aligns with the drive circuit design. Verify that the 6-pin DIP footprint matches the PCB layout constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of single-channel optocouplers. Unlike the CNY17-4 which typically lacks base access, the CNY17-4M variant exposes the phototransistor base pin, allowing for external biasing or faster discharge capabilities.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other Lite-On CNY17-4 variants with matching base access, such as CNY17-4-V. Cross-brand replacements must match the 6-DIP package, 5kV isolation, and NPN phototransistor output type.
