VO0630T

Overview

The VO0630T is a high-speed logic output optocoupler manufactured by Vishay Semiconductor Opto Division. It features two channels with an open collector, Schottky-clamped transistor output configuration. The device supports data rates up to 10MBd and provides 4000Vrms isolation voltage. Key electrical parameters include a maximum propagation delay of 100ns for both low-to-high and high-to-low transitions, typical rise and fall times of 23ns and 7ns respectively, and a minimum common-mode transient immunity (CMTI) of 1kV/µs. It operates within a supply voltage range of 4.5V to 5.5V and functions across a temperature range of -40°C to 100°C.

Feature Summary

• Integrates GaAsP LED with high-gain photodetector IC for LVTTL/LVCMOS compatibility
• Open collector output with Schottky clamping for enhanced AC and DC isolation
• High common-mode transient immunity ensures reliable signal transmission in noisy environments

Applications

• Industrial communication interfaces requiring galvanic isolation
• Power supply feedback loops for noise immunity
• Microcontroller input/output isolation in embedded systems

Procurement Notes

Verify the specific suffix and package variant against the official datasheet before ordering. Confirm that the required CMTI rating meets system specifications, as standard versions may differ from high-immunity variants. Ensure the operating temperature range aligns with the application environment constraints.

Selection Notes

Select this component when dual-channel isolation with fast switching speeds is required. The open-drain output necessitates external pull-up resistors; ensure resistor values are compatible with the target logic family voltage levels. Consider the 1kV/µs CMTI limit for applications with high dv/dt noise sources.

Part Context

This part belongs to Vishay's VO06xx series of high-speed optocouplers designed for digital signal isolation. It utilizes a surface-mount 8-SOIC package to facilitate automated assembly. The series is engineered to replace slower relay-based or older optocoupler technologies in modern high-density PCB layouts.

Replacement Considerations

Direct substitutes include the VO0631-X001T for higher CMTI requirements or the VOIH063AT for lower voltage supply compatibility. Verify pinout compatibility and insulation clearance distances when cross-referencing with other manufacturers' equivalent parts.
