CNY17F4SD

Overview

The CNY17F4SD is a single-channel transistor output optocoupler manufactured by Fairchild Semiconductor. It integrates a Gallium Arsenide infrared emitting diode with an NPN phototransistor in a 6-SMD Gull Wing package. The device provides a maximum isolation voltage of 5300 Vrms and features a minimum collector-emitter breakdown voltage (BV CEO) of 70 V. It operates within a temperature range of -55°C to 100°C, supports a maximum forward current of 60 mA, and has a maximum power dissipation of 0.16 W.

Feature Summary

Integrates a Gallium Arsenide IRED coupled with an NPN phototransistor for signal transmission
Provides high electrical isolation capability suitable for separating circuit grounds
Offers high collector-emitter breakdown voltage for robust performance in switching applications

Applications

Power supply regulators
Digital logic inputs
Microprocessor inputs
Appliance sensor systems
Industrial controls

Procurement Notes

Verify the specific suffix 'F4' against the official datasheet to confirm the current transfer ratio group selection, as this variant denotes a specific gain binning category within the CNY17 series. Ensure the 6-SMD Gull Wing package matches the design footprint requirements. Confirm RoHS compliance status if required by the assembly process, noting that standard variants may differ from white package options.

Selection Notes

Select this component when a single-channel isolation interface is required with moderate speed and high voltage tolerance. The 70 V minimum BV CEO makes it suitable for general-purpose switching rather than high-voltage industrial mains sensing. Consider the surface-mount form factor for automated assembly processes. Evaluate the thermal management needs given the 0.16 W power dissipation limit in enclosed environments.

Part Context

The CNY17 series comprises phototransistor optocouplers designed for general-purpose isolation tasks. This model belongs to the F-series variants, which specify particular current transfer ratio groups compared to the standard CNY17-4. The series is widely used in consumer electronics and industrial equipment where cost-effective galvanic isolation between low-voltage control circuits and higher-voltage power stages is necessary.
