CNY17-3X009T

Transistor, Photovoltaic Output Optoisolators Overview

The CNY17-3X009T is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with an accessible base terminal, housed in a 6-SMD gull-wing package. The device provides 5000Vrms isolation voltage and operates within a temperature range of -55°C to 110°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a DC forward current limit of 60mA, and a typical forward voltage of 1.39V. The current transfer ratio ranges from 100% to 200% at 10mA input. Switching characteristics include typical turn-on/turn-off times of 3µs/2.3µs and rise/fall times of 2µs/2µs.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix X009T to confirm the current transfer ratio binning (100%-200%) and the presence of the base terminal. Ensure the procurement order matches the required 6-SMD gull-wing package style. Confirm RoHS compliance status if restricted material usage is mandated for the target application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a base-accessible phototransistor is required for improved linearity or speed compared to standard variants. Compare the 100%-200% CTR range against application requirements to ensure sufficient gain margin. Evaluate the 6-SMD package constraints against PCB layout space limitations and thermal management needs for the specific design.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of transistor-output optocouplers. The '3' designation typically indicates the specific current transfer ratio binning, while 'X009T' denotes the tape-and-reel packaging configuration. It shares the same physical package and basic isolation ratings as other CNY17 variants but differs in optical efficiency specifications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include CNY17-2X009T and CNY17-4X009T, which share the same package and isolation rating but differ in current transfer ratio bins. Verify that the alternative CTR range meets the specific gain requirements of the circuit design before substitution.
