CNY17F1

Overview

The onsemi CNY17F1 is a single-channel optocoupler featuring an NPN phototransistor output. It provides high isolation voltage of 5300Vrms, suitable for general-purpose signal isolation. The device operates with a DC input and supports a maximum forward current of 60mA. Typical rise and fall times are 4μs and 24μs respectively. It offers a minimum current transfer ratio of 40% at 10mA input. The component is housed in a standard 6-pin DIP package and functions within a temperature range of -40°C to +100°C.

Feature Summary

• Provides robust electrical isolation between input and output circuits
• Features a single channel with NPN phototransistor output
• Designed for general-purpose signal transmission applications

Applications

• General-purpose signal isolation
• Industrial control systems
• Power supply feedback loops

Procurement Notes

Verify the specific suffix (e.g., M, SM) as it determines the package type and compliance status. Confirm RoHS and REACH declarations against the latest datasheet revision. Check for obsolete status or lifecycle notices from onsemi before finalizing procurement plans.

Selection Notes

Select this component when high isolation voltage is required for single-channel applications. Ensure the DIP-6 package fits the PCB layout constraints. Verify that the 40% minimum CTR meets the drive requirements of the downstream circuitry under all operating conditions.

Part Context

The CNY17F1 belongs to the CNY17 series of optocouplers manufactured by onsemi. This series is widely used for basic isolation tasks. The F1 variant specifically denotes the transistor output configuration with defined electrical characteristics distinct from other variants in the family.

Replacement Considerations

Direct substitutes include CNY17F1M for through-hole packaging. Surface-mount equivalents like CNY17F1SR2VM offer similar functionality in SMD packages. Verify pinout compatibility and isolation ratings when cross-referencing.
