CNY17F2M

Overview

The CNY17F2M is a single-channel transistor output optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode with an NPN phototransistor in a 6-pin PDIP package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum forward current of 60 mA, and an isolation voltage of 4170 Vrms. The device exhibits a typical rise time of 6 µs and a fall time of 24 µs, with a current transfer ratio ranging from 63% to 125%.

Feature Summary

• Integrates a gallium arsenide infrared LED coupled with an NPN phototransistor for signal transmission.
• Provides high-voltage isolation between input and output circuits via reinforced insulation.
• Features a standard 6-pin dual in-line package suitable for through-hole mounting.

Applications

• General-purpose digital signal isolation in industrial control systems.
• Interface circuits for microprocessors and logic devices requiring galvanic separation.
• Power supply feedback loops for monitoring and regulation.

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure the selected variant matches the required isolation voltage rating and operating temperature range for the target application environment. Cross-reference manufacturer part numbers with distributor listings to confirm authenticity and availability status.

Selection Notes

Select this component when a cost-effective, general-purpose optocoupler with moderate speed is required. Consider the 63-125% current transfer ratio for driving logic inputs directly. Verify that the 70 V collector-emitter voltage rating exceeds the load voltage requirements. Ensure the 60 mA forward current limit aligns with the driving circuit capabilities.

Part Context

This device belongs to the CNY17 family of transistor output optocouplers. It shares functional similarities with variants such as CNY17F1SM and CNY17F2SR2VM, differing primarily in packaging and specific electrical tolerances. The CNY17 series is widely used in applications requiring reliable electrical isolation between low-voltage control circuits and higher-voltage loads.

Replacement Considerations

Direct substitutes include other CNY17 series variants like CNY17F1 or CNY17F2, provided pin compatibility and electrical ratings match. Alternative manufacturers may offer equivalent parts, but verification of isolation voltage and current transfer ratio is essential before substitution.
