Transistor, Photovoltaic Output Optoisolators Applications

• Signal transmission isolation between circuits of different potentials
• Power supply feedback control loops
• Impedance matching between disparate circuit levels

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 300E confirms the required gull wing surface mount package variant. Ensure the procurement specification matches the exact manufacturer part number to avoid confusion with through-hole or tape-and-reel alternatives. Confirm RoHS compliance status if required by assembly standards. Cross-reference the datasheet for any recent design changes that may affect pinout or thermal characteristics.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a compact surface-mount solution is required for low-speed digital isolation. The 70 V collector-emitter rating suits general-purpose switching applications. Verify that the 5000 Vrms isolation voltage meets the safety requirements of the target application environment. Consider the 10 µs response time limitations for high-frequency signaling needs.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the CNY17 series of transistor output optocouplers produced by Broadcom Limited. The series is widely recognized for providing reliable electrical isolation in industrial and consumer electronics. The CNY17-4-300E specifically denotes the version packaged in a six-pin surface-mount format, distinguishing it from standard through-hole DIP variants within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other CNY17 series variants such as CNY17-2 or CNY17-3, provided the package type difference is accommodated by the PCB layout. Alternative packages like W00E offer identical electrical performance but utilize through-hole pins instead of surface-mount leads.
