VOH263A-X016

Overview

The VOH263A-X016 is a high-speed dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain logic output configuration with a data rate of 10 MBd and a common-mode transient immunity (CMTI) of 15 kV/µs. The device operates within an isolation voltage of 5000 Vrms and supports a forward current of 20 mA with a forward voltage of 1.38 V. Electrical characteristics include rise and fall times of 11 ns, a reverse voltage rating of 5 V, and an output current capacity of 50 mA. Power dissipation is rated at 85 mW, and the unit functions across a temperature range from -40°C to +110°C.

Feature Summary

• Dual-channel architecture providing independent signal isolation paths within a single package
• High common-mode transient immunity of 15 kV/µs for reliable operation in noisy environments
• Open-drain logic output interface compatible with standard digital logic families
• Fast switching performance with 11 ns rise and fall times supporting 10 MBd data rates

Applications

• Digital isolation in high-speed communication interfaces
• Signal transmission between microcontrollers and peripheral devices
• Noise-immune isolation in industrial control systems
• Gate drive isolation for power electronics applications

Procurement Notes

Verify the specific suffix X016 against official Vishay documentation to confirm packaging and tape-and-reel specifications. Ensure the required CMTI rating of 15 kV/µs aligns with system noise requirements. Confirm that the open-drain output topology matches the destination circuit's pull-up configuration. Validate thermal management capabilities given the 85 mW power dissipation limit in enclosed assemblies.

Selection Notes

Select this component when dual-channel isolation is required alongside high-speed data transmission capabilities. The open-drain output necessitates external pull-up resistors, which must be sized to maintain signal integrity at 10 MBd. Consider the DIP-8 through-hole package constraints if PCB layout requires manual assembly or reworkability. Evaluate the 5000 Vrms isolation barrier against regulatory safety standards applicable to the target equipment design.

Part Context

This device belongs to Vishay's high-speed optocoupler family, designed for robust signal transfer across isolated boundaries. The VOH263A series specifically targets applications demanding fast response times and high noise immunity. The X016 suffix typically denotes specific manufacturing or packaging variations within the broader VOH263A product line, distinguishing it from single-channel variants like the VOWH260A.

Replacement Considerations

Direct substitutes may include other Vishay dual-channel high-speed optocouplers with similar pinouts and electrical ratings. Verify compatibility regarding CMTI specifications and output stage configurations before substitution. Single-channel alternatives require circuit redesign to accommodate separate components. Consult official cross-reference guides for validated replacements ensuring identical isolation voltages and speed characteristics.
