CNW11AV1

Transistor, Photovoltaic Output Optoisolators Overview

The CNW11AV1 is a single-channel optoisolator manufactured by onsemi, featuring a transistor output with an accessible base terminal. It provides 4000Vrms isolation voltage and operates in a 6-DIP package. The device supports a maximum DC forward current of 100 mA and delivers a collector-emitter saturation voltage of up to 400 mV. It offers a minimum collector-emitter voltage of 70 V and a current transfer ratio ranging from 100% to 300% at 10 mA input. This component is designed for through-hole mounting and is currently classified as obsolete.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides electrical isolation between input and output circuits via an internal LED and phototransistor structure.
• Includes an exposed base terminal on the output transistor to allow for external circuit control or biasing adjustments.
• Ensures signal integrity across high-voltage barriers with a rated isolation voltage of 4000Vrms.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Microcontroller interface isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity due to obsolete status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pinout compatibility with existing PCB layouts before integration. Check for available surplus stock from authorized distributors. Ensure substitute parts meet all electrical specifications if original supply is unavailable.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a base-accessible phototransistor output is required for specific biasing needs. Consider the 4000Vrms isolation rating for safety-critical applications. Evaluate the 100 mA forward current limit against system drive requirements. Compare performance metrics with active alternatives like the CNY171M if long-term availability is a priority.

Transistor, Photovoltaic Output Optoisolators Part Context

The CNW11AV1 belongs to the CNW11 series of optocouplers from onsemi. It shares functional similarities with other transistor-output isolators but distinguishes itself through the inclusion of a base terminal. This series is designed for general-purpose isolation tasks where standard phototransistor outputs are insufficient for specific circuit configurations.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The CNY171M is listed as a similar replacement option. Verify that the substitute maintains equivalent isolation voltage and current transfer ratio specifications. Ensure package dimensions and pinout compatibility match the original design constraints.
