Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation during procurement to ensure correct packaging configuration. The base model CNY17-4-000E typically utilizes tube packaging, whereas variants such as 300E indicate bent-lead SMD options and 500E denotes tape-and-reel formats. Confirm that the received components match the required mounting style and reel specifications for automated assembly processes. Cross-reference the manufacturer part number against official Broadcom documentation to avoid confusion with similar series members.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and compact DIP-6 packaging are required for DC input applications. The device is suitable for designs needing moderate speed performance with typical 5 µs response times. Ensure the application circuit can accommodate the specified 1.7 V forward voltage drop and 60 mA maximum input current limits. Consider thermal dissipation requirements given the 250 mW power rating and verify that the 70 V collector-emitter voltage exceeds the maximum load voltage in the target circuit.
