CNY17F3SVM

Overview

The CNY17F3SVM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output without a base terminal, housed in a 6-SMD Gull Wing package. The device provides an isolation voltage of 4170 Vrms and supports a maximum collector-emitter voltage of 70 V with a continuous collector current of 50 mA. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.65 V, and a collector-emitter saturation voltage of 400 mV. The current transfer ratio ranges from 100% to 200%, with rise and fall times of 6 µs and 24 µs respectively. It operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via an internal LED and phototransistor structure.
• Features an NPN phototransistor output configuration designed for digital signal transmission applications.
• Offers robust insulation capabilities suitable for protecting low-voltage control circuits from high-voltage noise.

Applications

• Digital signal isolation in industrial control systems
• Signal transmission between microcontrollers and power stages
• Noise immunity enhancement in measurement equipment

Procurement Notes

Verify the specific suffix 'SVM' against the manufacturer's official datasheet to confirm the exact packaging type and tape-and-reel specifications. Ensure compliance with RoHS directives as indicated in the component documentation. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. The 6-SMD package facilitates automated assembly processes. Consider the 100-200% current transfer ratio range for circuit gain calculations. Verify that the 4170 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This component belongs to the CNY17 series of transistor output optocouplers produced by onsemi. The series is widely utilized for general-purpose isolation tasks. The 'F3' designation typically indicates a specific binning of the current transfer ratio, distinguishing it from other variants like F1 or F4 which may have different gain characteristics. The SMD variant adapts the traditional DIP form factor for modern surface-mount technology needs.

Replacement Considerations

Compatible alternatives within the same family include CNY17F3SR2VM and CNY17F3SM. These parts share similar electrical characteristics but may differ in packaging format (e.g., reel vs. bulk) or specific manufacturing lot variations. Verify pinout compatibility and thermal performance before substitution.
