VO0631-X001T

Overview

The VO0631-X001T is a dual-channel logic output optoisolator manufactured by Vishay Semiconductor Opto Division. It features an open-drain output configuration with a maximum data rate of 10MBd and a common-mode transient immunity (CMTI) of 5kV/µs. The device provides 4000Vrms isolation voltage and operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a typical forward voltage of 1.4V, a maximum DC forward current of 15mA, and an output current per channel of 50mA. Propagation delays are specified at 100ns for both low-to-high and high-to-low transitions, with typical rise and fall times of 23ns and 7ns respectively. It is housed in an 8-SOIC package.

Feature Summary

• Dual-channel architecture providing independent signal isolation paths within a single compact surface-mount package.
• High-speed logic output capability supporting data rates up to 10MBd for efficient digital communication.
• Robust noise immunity characterized by a minimum common-mode transient immunity of 5kV/µs.
• Open-drain output stage design allowing flexible interfacing with various logic families.

Applications

• Industrial automation control systems requiring galvanic isolation between microcontrollers and power stages.
• Ground loop elimination in noisy environments where signal integrity is critical.
• Interface circuits connecting low-voltage digital logic to higher-voltage peripheral devices.
• Signal transmission across isolated boundaries in measurement and testing equipment.

Procurement Notes

Verify the specific suffix -X001T against the manufacturer's official datasheet to confirm it matches the required pinout and internal component specifications. Ensure that the procurement source provides valid traceability documentation. Confirm compliance with RoHS3 standards as indicated in the environmental classification. Cross-reference the ordering part number with the supplier's catalog to avoid substitution errors with similar variants like the standard VO0631T.

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; ensure the system design accounts for this requirement. Verify that the operating temperature range of -40°C to 100°C meets the environmental constraints of the target application. Consider the 8-SOIC package dimensions for PCB layout compatibility and thermal management requirements.

Part Context

This device belongs to the VO06xxT family of high-speed optoisolators from Vishay. It shares architectural similarities with single-channel variants such as the VO0601T but offers doubled channel density. The product line emphasizes high CMTI and fast propagation speeds suitable for modern digital interfaces. It is designed to replace older relay or transformer-based isolation solutions in space-constrained designs.

Replacement Considerations

Direct substitutes within the same family include the VO0631T for standard packaging variations. For single-channel applications, the VO0601T may serve as a functional alternative if only one isolation path is needed. Always verify pin compatibility and electrical ratings before substituting with other manufacturers' parts.
