Overview
The CNY651AGRST is a single-channel transistor output optocoupler from Vishay, housed in a surface-mount 4-SMD package. It features an NPN phototransistor output with a maximum collector-emitter voltage of 32 V and a continuous collector current of 50 mA. The device provides high isolation capability of 8200 Vrms. Key electrical parameters include a forward current of 75 mA, a forward voltage of 1.32 V typical, and a collector-emitter saturation voltage of 300 mV maximum. The current transfer ratio ranges from 100% to 300%. Switching characteristics specify rise and fall times of 2.4 µs and 2.7 µs, respectively. It operates within a temperature range of -55°C to +85°C.
Feature Summary
- Provides reinforced electrical isolation for safety-critical applications
- Utilizes a compact surface-mount SMD-4 package design
- Features high-speed switching capabilities with low propagation delay
Applications
- Industrial control systems requiring galvanic isolation
- Safety circuits in consumer appliances
- Signal transmission across isolated ground potentials
Procurement Notes
Verify the specific suffix '1' in the part number CNY651AGRST against official Vishay documentation to confirm it denotes the correct isolation rating variant. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference datasheet revision dates to confirm current specifications before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage is required in a small footprint. Compare the 8200 Vrms rating against standard 5000 Vrms alternatives if space permits. Verify that the 50 mA output current capacity meets the load requirements of the receiving circuit. Consider the SMD-4 package constraints during PCB layout planning.
Part Context
This component belongs to the CNY series of optocouplers manufactured by Vishay Semiconductor Opto Division. It shares functional similarities with the CNY64 and CNY65 series but is distinguished by its specific high-isolation voltage rating and surface-mount packaging configuration designed for automated assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Vishay's official cross-reference tools or datasheets for verified equivalents.
