VO2630

Overview

The VO2630 is a dual-channel high-speed logic output optoisolator manufactured by Vishay Semiconductor Opto Division. It features an open drain output configuration with a data rate of 10MBd and a propagation delay of 75ns maximum for both low-to-high and high-to-low transitions. The device provides 5300Vrms isolation voltage and supports a supply voltage range of 4.5V to 5.5V. It operates within a temperature range of -40°C to 100°C and utilizes an 8-DIP package.

Feature Summary

• Dual-channel architecture providing independent signal isolation paths
• High common-mode transient immunity ensuring reliable operation in noisy environments
• Open drain output structure compatible with standard logic families
• High-speed data transmission capability suitable for digital communication interfaces

Applications

• Digital isolation in microcontroller systems
• Signal coupling between different ground potential domains
• Industrial control interface circuits
• Power supply feedback loops requiring galvanic isolation

Procurement Notes

Verify the specific package variant, as the VO2630 base number includes both surface mount and through-hole options. Confirm the required isolation voltage rating matches the application safety standards. Check for RoHS compliance status if environmental regulations apply. Ensure the operating temperature range covers the intended environment. Validate pinout compatibility with existing PCB footprints before ordering.

Selection Notes

Select this component when dual-channel isolation is required at high speeds. The open drain output necessitates external pull-up resistors for proper logic level generation. Consider the 1kV/µs CMTI rating against the noise environment. Compare propagation delays with system timing requirements. Evaluate thermal performance within the specified operating temperature range.

Part Context

The VO2630 belongs to Vishay's VO series of high-speed optocouplers. It shares functional similarities with other models in the series but differs in channel count and package type. The device is designed to replace legacy components in high-speed digital isolation applications. It offers a robust solution for separating noisy power sections from sensitive control electronics.

Replacement Considerations

Public confirmed substitute part numbers include VO2631-X017T for surface mount variants with higher CMTI ratings.
