CNY172TM

Transistor, Photovoltaic Output Optoisolators Overview

The CNY172TM is a transistor output optocoupler manufactured by onsemi, housed in a 6-pin dual in-line package (DIP). It integrates an aluminum gallium arsenide infrared emitting diode with a phototransistor output. The device provides electrical isolation between input and output circuits, featuring a high collector-emitter breakdown voltage (BVCEO) characteristic of the CNY172 series. This component is designed for applications requiring reliable signal transmission across isolated domains.

Transistor, Photovoltaic Output Optoisolators Feature Summary

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against the official onsemi datasheet to confirm pinout configuration and packaging variant. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm lead times and production status directly with the supplier before placing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard DIP-6 form factor is required for through-hole mounting. The integrated base allows for faster turn-off times compared to baseless variants. Verify that the required isolation voltage and current transfer ratio meet the specific circuit design constraints. Consider thermal management requirements based on the expected forward current of the internal LED.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the CNY172 family of optocouplers from onsemi. It shares functional similarities with other industry-standard transistor output isolators but offers specific performance characteristics defined by onsemi's manufacturing process. The product line is widely used in industrial and consumer electronics for galvanic isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include the CNY172M or CNY172VM from onsemi, provided the pinout and electrical specifications match the application requirements. Other generic equivalents should be verified for compatible isolation voltage and current transfer ratio.
