Overview
The CNY17F1SR2VM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output with no base connection, housed in a surface-mount 6-SMD (gull-wing) package. The device provides electrical isolation with a rated insulation voltage of 4170 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA. The forward current rating is 60 mA, with a typical forward voltage of 1.35 V. The current transfer ratio ranges from 40% to 80% at a forward current of 10 mA. Operating temperature spans from -40°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
- Features a compact surface-mount gull-wing package designed for automated assembly and space-constrained PCB layouts.
- Offers reliable signal transmission with defined current transfer ratios suitable for digital logic interfacing.
Applications
- Industrial control systems requiring isolated signal transmission
- Consumer electronics with safety isolation requirements
- Computer peripheral interfaces needing galvanic isolation
Procurement Notes
Verify the specific suffix 'SR2VM' against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with official distributor catalogs to distinguish it from through-hole variants or different packaging options within the CNY17F1 family.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with high voltage ratings. Compare the 4170 Vrms insulation rating against system safety standards. Evaluate the 40-80% current transfer ratio range to ensure adequate noise margin for the target application logic levels. Consider the 6-SMD footprint constraints during PCB layout design.
Part Context
This part belongs to the CNY17F1 series of transistor output optocouplers from onsemi. The series is characterized by its use of gallium arsenide infrared LEDs coupled with silicon NPN phototransistors. The SR2VM designation specifically indicates the surface-mount gull-wing package configuration and reel packaging format, distinguishing it from DIP or other SMD variations.
Replacement Considerations
Direct replacements must match the 6-SMD gull-wing package and 4170 Vrms isolation rating. Verify that substitute parts maintain similar current transfer ratio characteristics and collector-emitter voltage limits. Check for pin-to-pin compatibility if board rework is required.
