CNY17F4TVM

Overview

The CNY17F4TVM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and provides high isolation voltage of 4170 Vrms. The device operates within a temperature range of -40°C to +100°C. Key electrical parameters include a minimum current transfer ratio (CTR) of 160%, a maximum collector-emitter saturation voltage of 400 mV, and a maximum collector current of 50 mA. The forward voltage is typically 1.65 V at 60 mA forward current. Switching characteristics include a rise time of 4 µs and a fall time of 3.5 µs. The component is housed in a 6-DIP package.

Feature Summary

• High isolation voltage capability for safe signal transmission between isolated circuits
• Fast switching performance with low rise and fall times for efficient data transfer
• High current transfer ratio ensuring reliable output signal strength

Applications

• Industrial control systems requiring galvanic isolation
• Signal isolation in microprocessor-based circuits
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix TVM indicates tape and reel packaging when ordering. Confirm the CTR bin matches application requirements as variations exist within the same part number family. Ensure the 6-DIP package dimensions align with PCB layout constraints. Check for RoHS compliance status if required by project specifications. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when high CTR and fast switching are critical for signal integrity. Consider the 4170 Vrms isolation rating for safety-critical applications. Evaluate thermal management needs given the operating temperature range up to 100°C. Compare against other CNY17 variants if different CTR levels or packaging options are preferred. Ensure input current limits are respected to prevent LED degradation.

Part Context

This device belongs to the CNY17 series of transistor output optocouplers from onsemi. The series offers various CTR grades and packaging options to suit different design needs. The CNY17F4 variant specifically denotes a higher CTR grade compared to standard versions. These components are widely used in general-purpose isolation applications due to their reliability and cost-effectiveness.

Replacement Considerations

Direct substitutes may include other CNY17 series parts with similar CTR ratings. Verify pinout compatibility before substitution. Check isolation voltage and switching speed requirements against alternative models. Ensure package type matches existing board space constraints.
