CNX36UW

Transistor, Photovoltaic Output Optoisolators Overview

The CNX36UW is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output with a base terminal for enhanced switching control and stability. The device provides high isolation voltage of 5300 Vrms between the input LED and output transistor. Key electrical parameters include a maximum collector-emitter voltage (Vceo) of 30 V, a maximum collector current (Ic) of 100 mA, and a forward current (If) rating of 100 mA. The typical current transfer ratio (CTR) is 200%. It operates within a temperature range of -40°C to +100°C and is housed in a surface-mount SMD-DIP-6 package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix and date code against the latest datasheet revision. Check for obsolescence status as some variants may be discontinued. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate that the SMD-DIP-6 footprint matches the target PCB design requirements before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and fast switching are required in a compact form factor. The integrated base pin offers advantages over standard phototransistors in noisy environments. Consider the 30 V collector-emitter voltage limit for low-side switching applications. Evaluate the 200% CTR to ensure sufficient drive capability for downstream logic inputs. Compare thermal dissipation characteristics against the 200 mW power rating for dense layouts.
