VO2611

Overview

The VO2611 is a high-speed single-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open drain output and supports data rates up to 10 Mb/s. The device provides an insulation voltage of 5300 Vrms and a common-mode transient immunity (CMTI) of 15 kV/µs. Key electrical parameters include a forward current of 10 mA, a forward voltage of 1.4 V, and a maximum collector current of 50 mA. Timing characteristics specify a rise time of 23 ns and a fall time of 7 ns. The component operates within a specified temperature range and dissipates up to 85 mW.

Feature Summary

• High-speed signal transmission capability supporting 10 Mb/s data rates
• Enhanced noise immunity with 15 kV/µs common-mode transient rejection
• Robust isolation barrier rated at 5300 Vrms for safety compliance
• Open drain output configuration suitable for logic interfacing

Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems needing noise-resistant signal transmission
• Power supply feedback loops with fast response requirements
• Microcontroller input isolation in noisy electromagnetic environments

Procurement Notes

Verify the specific package variant during procurement, as the VO2611 designation may correspond to different mounting styles such as surface mount or through-hole configurations depending on the suffix. Confirm RoHS compliance status and ensure the selected part matches the required lead form factor for your assembly process. Cross-reference the manufacturer's latest datasheet to validate pinout compatibility and thermal specifications before finalizing orders.

Selection Notes

Select this component when designing circuits that demand both high data throughput and strong isolation performance. The 15 kV/µs CMTI rating makes it suitable for applications with significant switching noise. Ensure the driving circuit can provide the necessary 10 mA forward current to achieve optimal speed. Consider the open drain output topology when designing pull-up resistor networks for the receiving logic stage.

Part Context

The VO2611 belongs to Vishay's family of high-speed optocouplers designed for demanding digital isolation applications. It complements other models like the VO2611-X007T and VO2611-X017T, which share similar electrical characteristics but differ in packaging or tape-and-reel specifications. This series addresses the need for reliable signal transfer across isolation barriers in modern electronic systems.

Replacement Considerations

Direct substitutes include the 6N137 series from Vishay, which offers comparable open-drain outputs and high-speed performance. Verify that alternative components match the 10 Mb/s data rate requirement and the 5300 Vrms isolation voltage. Check pinout compatibility if replacing in existing PCB layouts to avoid redesign efforts.
