CNY17F-1SM

Transistor, Photovoltaic Output Optoisolators Overview

The CNY17F-1SM is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an infrared LED input and an NPN silicon phototransistor output, housed in a 6-SMD gull-wing package. Key electrical parameters include a maximum collector-emitter voltage of 30V, a peak forward current of 100mA, and a typical forward voltage of 1.15V. The device provides 5300Vrms isolation voltage and supports a collector current up to 60mA. It operates within a temperature range of -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the manufacturer designation carefully, as Isocom Components 2004 LTD produces equivalents to standard industry parts. Confirm the specific suffix indicates the correct surface-mount gull-wing package variant. Check datasheets for exact timing characteristics and thermal limits before integration into final designs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a low-cost, general-purpose transistor-output isolator is required for surface-mount applications. Ensure the 60mA collector current rating meets load requirements. Verify that the 5300Vrms isolation voltage satisfies safety standards for the target application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 family of optocouplers, which are widely used for basic isolation tasks. The 'F' suffix typically denotes a specific Current Transfer Ratio (CTR) bin, while 'SM' indicates the surface-mount package style. These devices serve as cost-effective alternatives to through-hole DIP variants in modern PCB layouts.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include MOC81043SD from onsemi or other CNY17F-1 equivalents from manufacturers like Vishay or Sharp. Verify pinout compatibility and ensure the replacement's CTR range matches the original design specifications.
