VOW2611-X017T

Overview

The VOW2611-X017T is a high-speed logic output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a single channel with an open collector output configuration, housed in an 8-SMD package. The device supports data rates up to 10 MBd and provides an isolation voltage of 5300Vrms. Key electrical parameters include a maximum DC forward current of 20mA, an output current per channel of 50 mA, and a typical forward voltage of 1.4V. Propagation delays are specified at 100ns for both low-to-high and high-to-low transitions, with rise and fall times of 14ns and 7ns respectively. It operates within a temperature range of -40°C to 100°C.

Feature Summary

• High common-mode transient immunity of 25kV/µs for noise-resistant signal transmission
• Widebody 8-SMD package design enabling 10 mm creepage distance for enhanced isolation safety
• Single-channel architecture optimized for high-speed digital signal isolation applications

Applications

• Industrial communication bus isolation
• Power supply feedback loop isolation
• Microcontroller interface protection

Procurement Notes

Verify the specific suffix X017T corresponds to the required tape and reel packaging format. Confirm that the 5300Vrms isolation rating meets the safety standards of the target application environment. Ensure the 25kV/µs CMTI specification is sufficient for the noise levels present in the circuit. Check RoHS compliance status if restricted substances are a concern for the final assembly process.

Selection Notes

Select this component when high-speed data transfer exceeding 1 MBd is required alongside robust galvanic isolation. The open collector output necessitates an external pull-up resistor; ensure the system design accommodates this requirement. Compare the 25kV/µs CMTI against lower-performance alternatives if the operating environment contains significant electromagnetic interference. Verify that the 8-SMD footprint fits the available PCB space constraints.

Part Context

This part belongs to Vishay's widebody high-isolation optocoupler family, designed for demanding industrial environments. The widebody package distinguishes it from standard narrow SMD packages by providing greater physical separation between input and output pins. This family prioritizes safety and signal integrity over compact size, making it suitable for applications where regulatory compliance and noise immunity are critical priorities.

Replacement Considerations

Direct substitutes within the same Vishay series include VOW137-X017T, which shares similar speed and isolation characteristics but may differ in specific CMTI ratings or pinout configurations. Cross-brand replacements require careful verification of propagation delay, output current capability, and isolation voltage to ensure functional equivalence without redesigning the surrounding circuitry.
