Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix X009T confirms the tape-and-reel packaging format when ordering. Ensure the design accommodates the 4-SMD鸥翼 (gull-wing) footprint dimensions. Confirm that the 40-80% CTR range meets the specific logic level requirements of the receiving circuit. Check RoHS compliance documentation if restricted substances are a constraint for the target application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for high-temperature applications exceeding standard 85°C limits. The wide CTR range allows for tolerance variation in driving currents. Compare against through-hole equivalents like VO615A-1 if board space permits, noting the pinout compatibility. Ensure the 50 mA collector current limit is sufficient for the load connected to the phototransistor collector.
