Overview
The VOH263A-X017T is a high-speed dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain output configuration and operates within a supply voltage range of 4.5V to 5.5V. The device provides 5000Vrms isolation voltage and supports data rates up to 10MBd. Key electrical parameters include a maximum forward current of 20mA, typical rise and fall times of 11ns, and a minimum common-mode transient immunity (CMTI) of 15kV/µs. It is housed in an 8-SMD package.
Feature Summary
- Dual-channel architecture for simultaneous signal isolation
- High common-mode transient immunity for noise rejection
- Open-drain logic output interface
- Surface-mount packaging for automated assembly
Applications
- Industrial communication bus isolation
- Data acquisition systems
- Power supply feedback loops
- Microcontroller input/output isolation
Procurement Notes
Verify the specific suffix X017T against official Vishay documentation to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with standard SMD reflow profiles. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current production status and RoHS compliance details before finalizing procurement orders.
Selection Notes
Select this component when dual-channel isolation with high-speed digital signaling is required. The 15kV/µs CMTI rating makes it suitable for noisy environments. Compare propagation delay and output current capabilities against system requirements. Consider the 8-SMD footprint constraints during PCB layout design relative to available space and thermal management needs.
Part Context
This device belongs to Vishay's high-speed optocoupler family, designed for applications requiring fast data transmission across isolation barriers. It complements single-channel variants like the VOH260A and other dual-channel models within the same series, offering standardized pinouts and performance metrics for scalable system designs.
Replacement Considerations
Direct substitutes may include other Vishay dual-channel high-speed optocouplers with compatible pinouts and electrical ratings. Verify equivalent CMTI and data rate specifications when considering alternative manufacturers or different Vishay part numbers.
