VOH263A-X007T

Overview

The VOH263A-X007T is a high-speed dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain logic output configuration housed in an 8-pin SMD package. The device supports a data rate of 10 MBd with typical rise and fall times of 11 ns each. It provides an isolation voltage of 5000 Vrms and a common-mode transient immunity of 15 kV/µs. Key electrical parameters include a maximum forward current of 20 mA, a forward voltage of 1.38 V, and an output current capability of 50 mA per channel.

Feature Summary

• Dual-channel architecture for simultaneous signal isolation
• High-speed operation supporting 10 MBd data rates
• Enhanced common-mode transient immunity for noise rejection
• Open-drain output interface compatible with standard logic families

Applications

• Industrial communication bus interfaces
• Isolated gate driver circuits
• Data acquisition systems requiring high-speed isolation
• Power supply feedback loops

Procurement Notes

Verify the specific suffix X007T to ensure correct packaging and reel specifications. Confirm that the 5000 Vrms isolation rating meets system safety requirements. Check for RoHS compliance status if required by project standards. Ensure the 8-SMD footprint matches the PCB layout design. Validate input current limits against drive circuit capabilities.

Selection Notes

Select this component when dual-channel isolation with high-speed performance is required. The open-drain output simplifies interfacing with various logic levels. Consider the 15 kV/µs CMTI for environments with significant electrical noise. Compare propagation delays against timing constraints. Evaluate thermal dissipation needs given the 85 mW power dissipation rating.

Part Context

This part belongs to Vishay's high-speed optocoupler family, designed for demanding digital isolation applications. It complements single-channel variants like the VO2630 by providing two isolated channels in one compact package. The series emphasizes fast switching speeds and robust noise immunity for reliable data transmission across isolation barriers.

Replacement Considerations

Direct substitutes may include other dual-channel high-speed optocouplers from Vishay or competitors offering similar pinouts and electrical characteristics. Verify compatibility regarding isolation voltage, data rate, and output type before substitution.
