CNY17F2M

Overview

The CNY17F2M is a single-channel phototransistor optocoupler manufactured by Fairchild Semiconductor. It integrates a Gallium Arsenide infrared emitting diode with an NPN phototransistor in a 6-pin DIP package. The device features no base connection to pin 6, ensuring very low coupled capacitance for minimum noise susceptibility. It offers a high collector-emitter breakdown voltage (BVCEO) of at least 70V and supports an isolation voltage of 4170Vrms. The unit is RoHS compliant and available in a white package configuration.

Feature Summary

• Integrates a Gallium Arsenide IRED with an NPN phototransistor
• Features no chip-to-pin 6 base connection for reduced noise susceptibility
• Provides high collector-emitter breakdown voltage
• Available in UL recognized white package configuration

Applications

• Power supply regulators
• Digital logic inputs
• Microprocessor inputs
• Appliance sensor systems
• Industrial controls

Procurement Notes

Verify the specific suffix 'M' confirms the white package variant when sourcing. Confirm that the component is the CNY17F2M variant without base connection, distinct from standard CNY17 models. Ensure documentation references Fairchild Semiconductor or its successors as the original manufacturer. Check for UL recognition file E90700 compliance if safety certification is required for the end application.

Selection Notes

Select this component when low noise susceptibility is critical due to the absence of a base lead connection. Choose the CNY17F2M over standard variants if the white package option is specified for regulatory or environmental reasons. Ensure the application requires a single channel transistor output with high BVCEO characteristics suitable for digital isolation tasks.

Part Context

The CNY17F2M belongs to the CNY17 series of phototransistor optocouplers. This family includes variants like CNY17-1 through CNY17-4 and MOC810X devices. The 'F' designation typically indicates the 6-pin DIP package without base connection, while the 'M' suffix specifies the white package option. These components are designed for general-purpose isolation in industrial and consumer electronics.

Replacement Considerations

Equivalent parts include other 6-pin DIP optocouplers without base connections such as the MOC8103. Verify that substitute components maintain the same single-channel configuration and comparable isolation voltage ratings.
