CNY173FM

Transistor, Photovoltaic Output Optoisolators Overview

The CNY173FM is a single-channel transistor output optocoupler manufactured by onsemi. It features an infrared emitting diode coupled to an NPN phototransistor with a base terminal, housed in a surface-mount 6-SMD package. The device provides electrical isolation rated at 4170Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 70V, a peak forward current of 60mA, and a typical forward voltage of 1.35V. The unit supports a collector current of up to 50mA and operates within a temperature range of -40°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and check for any recent product change notices regarding material composition or manufacturing location changes before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation. Consider the base terminal availability if faster switching speeds or higher gain stability are needed compared to standard phototransistors without base access. Confirm that the 70V collector voltage rating meets the load requirements of the target application circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY series of optocouplers produced by onsemi. The FM suffix typically denotes a surface-mount variant, distinguishing it from through-hole DIP packages like the CNY173TVM. This family is widely used for basic digital signal isolation tasks where cost-effectiveness and reliability are prioritized over high-speed data transmission capabilities.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Cross-reference with other single-channel transistor output optocouplers offering similar 4170Vrms isolation ratings. Verify pinout compatibility and physical dimensions when substituting with parts from different manufacturers to ensure board layout integrity.
