CNY17F4TVM

Overview

The CNY17F4TVM is a single-channel transistor output optocoupler manufactured by Fairchild Semiconductor. It integrates a Gallium Arsenide infrared emitting diode with an NPN phototransistor within a 6-pin DIP package. The device provides electrical isolation with a rated insulation voltage of 7500 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a forward current rating of 60 mA, and a power dissipation capacity of 250 mW. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

• Integrates a Gallium Arsenide IRED coupled with an NPN phototransistor for signal transmission
• Provides high-voltage electrical isolation between input and output circuits
• Designed for through-hole mounting in standard 6-pin dual in-line packages

Applications

• General-purpose digital signal isolation
• Microprocessor system interface circuits
• Solid-state relay driver applications

Procurement Notes

Verify the manufacturer origin, as this component was produced by Fairchild Semiconductor prior to its acquisition by onsemi. Confirm the specific suffix 'TVM' corresponds to the required tape and reel or bulk packaging configuration. Ensure the part number matches the exact pinout and electrical specifications required for the design, as variations exist within the CNY17 family.

Selection Notes

Select this component when a standard NPN phototransistor output is required for cost-effective isolation. Consider the 7500 Vrms insulation rating for safety compliance. Evaluate the 6 us rise time and 24 us fall time against the required switching speed of the application. Ensure the PCB layout accommodates the 6-pin DIP footprint and maintains adequate creepage distances for the operating voltage.

Part Context

This device belongs to the CNY17 series of phototransistor output optocouplers. The series typically includes variants such as CNY171, CNY172, CNY173, and CNY174, which differ primarily in their Current Transfer Ratio (CTR) ranges. The CNY17F4TVM specifically denotes the CNY174 variant with particular packaging and handling specifications defined by the manufacturer's coding system.

Replacement Considerations

Direct replacements within the same family include CNY172FVM and CNY174FVM from onsemi/Fairchild. Verify that substitute parts maintain the same 6-pin DIP package and NPN phototransistor output type. Cross-referencing with other manufacturers requires checking equivalent isolation voltages and CTR specifications.
