VOH260A-X007T

Overview

The VOH260A-X007T is a high-speed single-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain logic output and operates with a data rate of 10 MBd. The device provides 5000Vrms isolation voltage and exhibits a common-mode transient immunity (CMTI) of 15kV/µs. Packaged in an 8-SMD surface-mount format, it supports a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum forward current of 15mA, a typical forward voltage of 1.38V, and an output current capability of 50mA per channel.

Feature Summary

• High-speed signal transmission capability supporting 10 MBd data rates
• Robust noise immunity characterized by 15kV/µs common-mode transient rejection
• Integrated open-drain output stage for direct logic interface compatibility

Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems subject to significant electrical noise
• Data acquisition circuits needing fast signal propagation with safety isolation

Procurement Notes

Verify the specific suffix X007T corresponds to the required tape-and-reel packaging configuration before ordering. Confirm that the 5000Vrms isolation rating meets the safety standards applicable to your target equipment. Ensure input drive currents remain within the specified 15mA maximum limit to maintain optimal switching performance and longevity. Cross-reference the 8-SMD package dimensions against your PCB footprint design files.

Selection Notes

Select this component when application requirements demand both high data throughput and exceptional noise resilience. The 15kV/µs CMTI specification makes it suitable for environments with rapid voltage fluctuations. Compare the open-drain output topology against push-pull alternatives to ensure compatibility with downstream logic families. Validate that the 8-SMD form factor fits within the constrained spatial limits of the enclosure.

Part Context

This device belongs to Vishay's high-speed optocoupler portfolio, designed for demanding industrial and commercial applications. It shares architectural similarities with other members of the VOH260 series but offers specific packaging and performance characteristics tailored for surface-mount assembly. The product line emphasizes reliability and speed in isolated signal transmission scenarios.
