CNY17F3VM

Overview

The CNY17F3VM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and is housed in a PDIP-6 through-hole package. The device provides an isolation voltage of 4170 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current of 60 mA. The current transfer ratio ranges from 100% to 200%. Operating temperatures span from -40°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using a phototransistor configuration.

Applications

• General-purpose signal isolation
• Microprocessor system interfacing
• Solid-state relay drivers

Procurement Notes

Verify the specific suffix 'VM' against the manufacturer's official datasheet to confirm the exact packaging format and material compliance status. Ensure the component matches the required DIP-6 through-hole mounting style for your PCB design. Cross-reference the RoHS declaration with the latest product change notices to confirm environmental compliance before procurement.

Selection Notes

Select this component when a standard NPN phototransistor output is required for basic digital signal isolation. The PDIP-6 package is suitable for through-hole assembly processes. Consider the 4170 Vrms isolation rating for applications requiring robust barrier protection. Verify that the 100% to 200% current transfer ratio meets the drive requirements of the receiving circuitry at the intended operating temperature range.

Part Context

This part belongs to the CNY17 series of transistor output optocouplers. The series is widely used for general-purpose isolation tasks. The 'VM' suffix typically denotes specific packaging or tape-and-reel variations within the broader CNY17 family. These devices are designed for reliable performance in industrial and consumer electronic applications requiring galvanic separation.

Replacement Considerations

Compatible substitutes include other CNY17 variants such as CNY17-1, CNY17-2, or CNY17-3, provided the current transfer ratio specifications align with the application needs. Ensure any replacement maintains the same PDIP-6 package and 4170 Vrms isolation rating.

FAQ
