CNY17F2VM

Overview

The CNY17F2VM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output with no base connection, housed in a 6-pin SMD-DIP package. Key electrical specifications include a maximum collector-emitter voltage of 70 V and a maximum collector current of 50 mA. The device provides an insulation voltage of 4170 Vrms and supports a forward current of 60 mA with a forward voltage of 1.65 V. Operating characteristics include a rise time of 6 µs and a fall time of 24 µs. Power dissipation is rated at 270 mW, with an operating temperature range from -40°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor pair.
• Features a surface-mount DIP-6 package design suitable for automated assembly processes.
• Offers high insulation voltage capability to protect low-voltage control circuits from high-voltage loads.

Applications

• Signal isolation in microprocessor-based control systems
• Switching power supply feedback loops
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix 'VM' against the manufacturer's latest datasheet to confirm pinout configuration and packaging type, as suffixes often denote tape-and-reel or bulk variations. Ensure compliance with RoHS directives if required for your assembly process. Cross-reference the component marking code with official documentation to authenticate the source and prevent counterfeit components.

Selection Notes

Select this component when a single-channel isolation barrier is required with moderate speed requirements. The NPN phototransistor output is suitable for sinking current applications. Consider the 4170 Vrms insulation rating for safety standards compliance. Evaluate the 6 µs rise time against system switching frequency needs to ensure adequate signal integrity without excessive delay.

Part Context

This part belongs to the CNY17F2M series of transistor output optocouplers. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The CNY17F2VM variant specifically utilizes the VM suffix to indicate its physical form factor and handling characteristics within the broader product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative optocouplers based on pinout, isolation voltage, and current transfer ratio requirements before substitution.
