CNY17-4X017

Transistor, Photovoltaic Output Optoisolators Overview

The CNY17-4X017 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base terminal for improved switching performance and noise immunity. The device provides 5000Vrms isolation voltage between input and output circuits. It operates within a temperature range of -55°C to 110°C and utilizes a 6-SMD surface-mount package.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrated base terminal on the NPN phototransistor enhances switching speed and reduces storage time.
• Provides robust electrical isolation with a rated insulation voltage of 5000Vrms.
• Designed for high reliability in through-hole or surface-mount applications requiring DC or low-frequency signal transmission.

Transistor, Photovoltaic Output Optoisolators Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic families
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix X017 against official Vishay documentation to confirm the exact tape-and-reel quantity and packaging configuration, as suffixes often denote specific shipping units rather than functional changes. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor databases to confirm current availability and lifecycle status before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a phototransistor output with a base pin is required for faster response times compared to standard variants without a base. Consider the 6-SMD footprint constraints and ensure the PCB layout supports the required creepage and clearance distances for the 5000Vrms isolation rating. Evaluate the Current Transfer Ratio (CTR) specifications at the intended forward current to ensure adequate signal margin for the application.

Transistor, Photovoltaic Output Optoisolators Part Context

This component belongs to the CNY17 family of optocouplers, which are widely used for general-purpose isolation. The '4' designation typically indicates a specific Current Transfer Ratio (CTR) bin, while 'X017' denotes the surface-mount packaging variant. This family offers a balance of performance and cost-effectiveness for basic isolation tasks.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include other Vishay CNY17 series variants with compatible packages, such as CNY17-4X007T, provided the CTR bin and physical dimensions match. Verify that any substitute maintains the same 5000Vrms isolation rating and NPN phototransistor output type.
