CNY17F1VM

Overview

The CNY17F1VM is a single-channel transistor output 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 provides high isolation voltage of 7500Vrms and supports a collector-emitter breakdown voltage of 70V minimum. It operates within a temperature range of -40°C to 100°C, features a typical current transfer ratio of 40% at 10mA forward current, and includes a base terminal for improved switching performance.

Feature Summary

• Integrates a Gallium Arsenide IRED coupled with an NPN phototransistor for DC input signal isolation
• Provides high electrical isolation capability suitable for demanding industrial environments
• Includes a dedicated base terminal on the phototransistor to enhance switching speed and sensitivity

Applications

• Power supply regulators
• Microprocessor input interfaces
• Industrial control systems
• Digital logic input circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability from third-party sources. Confirm RoHS compliance status and specific manufacturing date codes against current project requirements. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity and isolation performance specifications.

Selection Notes

Select this component when high isolation voltage and fast switching response are required in compact DIP packaging. The integrated base terminal allows for optimized drive conditions compared to standard two-terminal phototransistors. Consider thermal management and PCB layout constraints associated with through-hole mounting in final design implementation.

Part Context

This part belongs to the CNY17 series of optocouplers, which are widely used for galvanic isolation in electronic circuits. The 'F' suffix typically denotes specific current transfer ratio grouping, while 'VM' indicates the white package variant with VDE approval. These devices are designed for general-purpose isolation applications requiring reliable signal transmission across isolated boundaries.

Replacement Considerations

Compatible substitutes include other CNY17 series variants such as CNY17-3SR2V-M for surface mount applications or equivalent transistor-output optocouplers with matching isolation ratings and pin configurations. Verify functional compatibility regarding current transfer ratios and switching times before substitution.
