CNY64AYST

Overview

The CNY64AYST is a single-channel phototransistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a collector-emitter breakdown voltage of 32 V and a maximum collector current of 50 mA. The device provides a very high isolation voltage of 8200 Vrms. It operates within a temperature range of -55°C to +85°C and is housed in a compact 4-SMD surface-mount package.

Feature Summary

Provides very high insulation voltage for robust electrical isolation
Utilizes a compact surface-mount package for space-constrained designs
Features an NPN phototransistor output for standard switching applications

Applications

Safe electrical isolation circuits compliant with DIN EN 60747-5-2
Signal transmission between isolated digital logic levels
Microcontroller interface circuits requiring galvanic separation

Procurement Notes

Verify the specific suffix 'AYST' confirms the 4-SMD surface-mount package and 8200 Vrms rating, as generic CNY64 variants may differ in packaging or isolation specifications. Ensure compliance with safety standards such as DIN EN 60747-5-2 if used for reinforced isolation. Confirm RoHS status and moisture sensitivity level requirements against the specific datasheet revision prior to ordering.

Selection Notes

Select this component when high isolation voltage is critical and surface-mount technology is required. Compare the 32 V collector-emitter voltage and 50 mA output current against load requirements. Consider the operating temperature range of -55°C to +85°C for environmental suitability. Verify that the 4-SMD footprint matches the PCB layout constraints.

Part Context

This part belongs to the Vishay CNY series of optocouplers, which are widely used for general-purpose signal isolation. The CNY64AYST specifically addresses the need for high-voltage isolation in a small form factor, distinguishing it from through-hole DIP versions like the CNY64ST while maintaining similar electrical performance characteristics for the phototransistor output stage.
