Overview
The CNY17F3SM is a single-channel optocoupler from onsemi featuring an NPN phototransistor output. It provides 4170 Vrms isolation voltage and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a collector current of 50mA, and a forward current of 60mA. The typical current transfer ratio ranges from 100% to 200% at 10mA input. Rise and fall times are typically 6µs and 24µs respectively. The device is housed in a 6-SMD MDIP package with gull-wing leads.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for digital signal transmission
- Designed for surface-mount assembly in compact electronic systems
Applications
- Industrial control system signal isolation
- Microcontroller interface protection
- Power supply feedback loops
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and performance characteristics. Ensure compatibility with RoHS3 standards if required by the target market. Confirm that the 6-SMD MDIP package dimensions match the PCB footprint design constraints. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability.
Selection Notes
Select this component when a single channel with moderate speed and high isolation voltage is required. The CNY17F3SM offers a balance of cost-effectiveness and reliability for general-purpose isolation tasks. Consider the current transfer ratio variations when designing bias networks for consistent switching performance across different operating temperatures.
Part Context
This device belongs to the CNY17 series of optocouplers, which are widely used for basic isolation needs. The 'F3' designation typically indicates a specific current transfer ratio bin compared to other variants like CNY17F4. These components are standard solutions for breaking ground loops and protecting sensitive logic circuits from high-voltage transients.
Replacement Considerations
Direct replacements may include CNY17F3SR2VM or CNY17F4SM, provided pinouts and electrical ratings are compatible. Verify that substitute parts meet the same isolation voltage and thermal requirements.
