CNY17-4S1(TB)-V

Transistor, Photovoltaic Output Optoisolators Overview

The CNY17-4S1(TB)-V is a surface-mount transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor with an accessible base terminal, housed in a 6-pin SMD package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. It operates within a temperature range of -55°C to +110°C. The current transfer ratio (CTR) is specified in the narrow group of 160% to 320%. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 60 mA, and a typical rise/fall time of 10 µs.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors due to limited availability. Confirm RoHS compliance status via official documentation. Check for lead-free packaging specifications. Validate pin configuration matches the specific suffix requirements. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this variant when an external base connection is required for the phototransistor to enhance switching characteristics. Compare against CNY17F series if no base access is needed. Verify that the surface mount package fits the PCB footprint constraints. Ensure the operating temperature range meets the application's environmental demands.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the CNY17-X family of transistor output optocouplers. The '4' designation indicates a high current transfer ratio group (160-320%). The 'S1' suffix denotes the surface mount package type, while '(TB)' specifies the tape and reel packaging format. This distinguishes it from through-hole variants like the CNY17-4.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other CNY17-4 series variants with compatible packaging. Verify pinout compatibility before substitution. Consider CNY17-4S1(TA)-V for different tape configurations. Ensure replacement parts maintain the same isolation voltage and CTR range.
