VO0611T

Overview

The VO0611T is a high-speed optocoupler from Vishay Semiconductor Opto Division, featuring a single channel with an open-drain output. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 10MBd. The device provides 4000Vrms isolation voltage and exhibits a common-mode transient immunity of 15kV/µs. Propagation delays are typically 100ns for both low-to-high and high-to-low transitions. It is housed in an 8-SOIC package and functions reliably across a temperature range of -40°C to 100°C.

Feature Summary

• High-speed signal transmission capability supporting 10MBd data rates
• Enhanced common-mode transient immunity of 15kV/µs for noise rejection
• Single-channel configuration with open-drain logic output
• Robust electrical isolation rated at 4000Vrms

Applications

• Industrial automation control systems
• Communication interface circuits
• Power supply feedback loops
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout and isolation ratings, as variants like VO0601T differ significantly in CMTI specifications. Ensure the ordering part number matches the required insulation class and package type. Cross-reference datasheet revisions to confirm compliance with current safety standards such as UL, cUL, and VDE before finalizing procurement.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The 15kV/µs CMTI rating distinguishes it from lower-performance variants in the same family. Consider the open-drain output requirement for pull-up resistor integration. Verify that the 8-SOIC package dimensions fit the target PCB layout constraints and thermal management requirements.

Part Context

The VO0611T belongs to the VO06xxT series of high-speed optocouplers designed for demanding industrial applications. This series emphasizes fast propagation times and high common-mode rejection capabilities. Unlike standard optocouplers, these devices utilize advanced LED and photodetector technologies to achieve megabit-per-second data rates while maintaining strict safety isolation barriers between input and output circuits.

Replacement Considerations

Direct substitutes include other Vishay VO06xxT series parts with matching CMTI ratings. Verify equivalent isolation voltage and package compatibility. Check if alternative manufacturers offer comparable 10MBd speed and 15kV/µs immunity in an 8-SOIC footprint.
