CNY171SR2M

Transistor, Photovoltaic Output Optoisolators Overview

The CNY171SR2M is a single-channel transistor output optocoupler manufactured by onsemi, designed for surface-mount applications. It features an NPN phototransistor with a base lead and offers high collector-emitter breakdown voltage (Bvceo). Key electrical parameters include a minimum current transfer ratio of 40% and a maximum of 80%, with a forward current rating of 60 mA and a forward voltage of 1.65 V. The device supports a maximum collector current of 50 mA and a collector-emitter voltage of 70 V. It provides an insulation voltage of 4170 Vrms and operates within a temperature range of -40°C to +100°C. The unit is housed in a 6-SMD DIP package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates an infrared emitting diode with an NPN phototransistor featuring a base terminal for enhanced switching control.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal isolation in microprocessor-based circuits
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2M' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure that the required current transfer ratio bin matches the application design constraints. Confirm RoHS compliance status and check for any regional regulatory restrictions applicable to the procurement region before finalizing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a low-cost, single-channel isolation solution with a base-controlled phototransistor is required. Consider the 40-80% current transfer ratio range for logic interface compatibility. Evaluate the 4170 Vrms insulation voltage for safety requirements. Compare rise and fall times against signal speed needs, as the device is suitable for general-purpose digital isolation rather than high-speed data transmission.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY171M series of high Bvceo phototransistor optocouplers. It shares functional similarities with other members of the family but differs in packaging and specific electrical tolerances. The SR2M designation indicates a specific surface-mount configuration distinct from through-hole variants like the standard CNY171.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include CNY171SR2VM or CNY173SR2M, provided the current transfer ratio and pinout compatibility are verified. Always cross-reference the replacement part's datasheet for differences in insulation voltage, operating temperature range, and package dimensions to ensure mechanical and electrical fit.
