CNY171TM

Transistor, Photovoltaic Output Optoisolators Overview

The CNY171TM is a single-channel optocoupler featuring an infrared LED coupled to a phototransistor with base lead. It utilizes a 6-pin DIP package with 0.4-inch lead spacing and is supplied in tubes of 50 units. Key electrical parameters include a minimum collector-emitter breakdown voltage (BVCEO) of 70 V, a maximum forward current of 60 mA, and a typical rise time of 4 µs. The device offers a current transfer ratio ranging from 40% to 80%, with a maximum dark power of 50 nA. It operates within a temperature range of -40°C to 100°C and supports isolation voltages up to 7500 V AC.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against official onsemi documentation to confirm tube packaging and lead spacing specifications. Ensure compliance with RoHS directives and check for UL or VDE approvals relevant to your target market. Confirm that the 6-pin MDIP package dimensions match your board layout requirements before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-controlled phototransistor functionality is required for improved linearity or switching speed compared to standard variants. Consider the 70 V BVCEO rating for applications involving moderate load voltages. Evaluate the 4 µs rise time against system timing constraints to ensure adequate performance for the intended data rate or switching frequency.

Transistor, Photovoltaic Output Optoisolators Part Context

Part of the CNY series, which includes variants like CNY171VM and CNY17F4M. The CNY171TM specifically denotes the tube-packaged version with defined lead spacing. It belongs to the broader category of transistor-output optocouplers designed for general-purpose isolation tasks in electronic circuits.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Cross-reference with CNY171VM for identical electrical characteristics but different packaging (bulk vs. tube). Verify pinout compatibility with existing designs when substituting.
