Overview
The CNY75GC is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an infrared emitting diode optically coupled to a phototransistor with a base terminal, housed in a 6-DIP package. The device provides 5000Vrms isolation voltage and supports a maximum collector current of 50mA. Key electrical parameters include a typical forward voltage of 1.39V, a saturation voltage of 400mV, and a current transfer ratio ranging from 160% to 320% at 10mA input current. Operating temperatures span from -55°C to 110°C.
Feature Summary
- Integrated base terminal on the phototransistor for improved switching speed and linearity control
- High isolation voltage capability of 5000Vrms for robust signal transmission across isolated domains
- Wide operating temperature range suitable for demanding industrial environments
Applications
- Industrial automation signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific Current Transfer Ratio (CTR) bin, as the CNY75GC denotes a 160-320% range which differs from other CNY75 variants. Confirm the package type is standard 6-DIP and check RoHS compliance status against the latest manufacturer documentation. Ensure the supplier source matches Vishay Semiconductor Opto Division to avoid counterfeit components.
Selection Notes
Select this component when high-speed switching is required compared to standard phototransistor outputs, due to the integrated base connection. Compare the 160-320% CTR range against application requirements for gain stability. Consider the 6-DIP form factor for through-hole mounting constraints and verify that the 50mA collector current meets load demands.
Part Context
This part belongs to the CNY75 series, which offers higher speed performance than the standard CNY17 family. It shares the same 6-DIP footprint but distinguishes itself with a wider CTR tolerance and faster rise/fall times. It serves as a direct upgrade for designs requiring better transient response while maintaining pin compatibility with similar DIP-6 isolators.
Replacement Considerations
The CNY75GB is a related variant within the same series but typically specifies a different CTR range (63-125%). Verify if the lower gain of the GB version meets circuit requirements before substitution. Other CNY75 models may share physical dimensions but differ electrically.
