VOH260A-X017T

Overview

The VOH260A-X017T is a high-speed optocoupler from Vishay Semiconductor Opto Division, featuring a single channel in an 8-pin SMD package. It operates with a data rate of 10 MBd and provides 5000 Vrms insulation voltage. The device utilizes an open drain output type, supporting a forward current (If) of 10 mA and a forward voltage (Vf) of 1.38 V. Key timing parameters include a rise time of 23 ns and a fall time of 10 ns. The component handles a reverse voltage (Vr) of 5 V, delivers an output current of 50 mA, and has a power dissipation (Pd) rating.

Feature Summary

• High-speed signal transmission capability for digital isolation applications
• Single-channel configuration within a compact surface-mount footprint
• Open-drain output architecture for flexible logic interfacing

Applications

• Digital communication interface isolation
• Microcontroller input/output isolation
• Signal transmission across isolated ground planes

Procurement Notes

Verify the specific suffix X017T to confirm the 8-pin SMD packaging and tape-and-reel delivery format. Ensure the required insulation voltage of 5000 Vrms meets system safety standards. Confirm that the 10 mA forward current requirement aligns with the driving circuit capabilities. Check RoHS compliance status if restricted substances are mandated by the end-use application regulations.

Selection Notes

Select this component when a single-channel high-speed solution is required in a surface-mount form factor. The open-drain output necessitates an external pull-up resistor for proper logic level generation. Compare propagation delay characteristics against system timing budgets. Consider the thermal management requirements associated with the specified power dissipation limit during continuous operation.

Part Context

This part belongs to the VOH260A series of high-speed optocouplers manufactured by Vishay. The series typically offers variants in both DIP and SMD packages. The X017T suffix specifically denotes the surface-mount variant with corresponding reel packaging. This family is designed for applications requiring fast data rates and reliable galvanic isolation between circuits.

Replacement Considerations

Direct replacements may include other Vishay parts within the same high-speed optocoupler family, such as the VOH260A-X006 for through-hole mounting. Verify pinout compatibility and electrical specifications before substitution. Cross-reference with industry-standard equivalents like the 6N137 series if package or parameter differences are acceptable.
