VOWH260A

Overview

The VOWH260A is a single-channel high-speed optocoupler manufactured by Vishay Semiconductor Opto Division. It features a 10 MBd data rate and operates within an ambient temperature range of -40°C to +110°C. The device utilizes an 8-pin DIP Wide Body package for through-hole mounting. Key electrical specifications include a 5000 Vrms insulation voltage, 10 mA forward current, and 50 mA output current. The logic output type is open drain, with rise and fall times of 23 ns and 10 ns respectively. Power dissipation is rated at 125 mW.

Feature Summary

• High-speed signal transmission capability up to 10 MBd
• Integrated high-efficiency input LED coupled with a high-speed integrated photo-detector logic gate
• Robust electrical isolation with 5000 Vrms insulation voltage rating
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation control systems
• Communication interface circuits requiring galvanic isolation
• Power supply feedback loops
• Signal isolation in noisy electronic environments

Procurement Notes

Verify the specific suffix code against official Vishay documentation to confirm package variant and compliance status. Ensure the procurement channel provides valid traceability for RoHS requirements. Confirm that the 8-pin DIP Wide Body package dimensions match the target PCB footprint design constraints before finalizing orders.

Selection Notes

Select this component when high-speed digital isolation is required between circuits with significant potential differences. The open-drain output necessitates appropriate pull-up resistor configuration based on the target logic voltage levels. Consider the thermal management requirements given the 125 mW power dissipation limit in enclosed spaces.

Part Context

This part belongs to Vishay's high-speed optocoupler family designed for robust signal integrity. It differs from standard variants by offering enhanced speed and wider body packaging for improved creepage distances. The technology combines LED input with integrated photodetector logic for reliable noise immunity in complex electronic assemblies.

Replacement Considerations

Direct substitutes may include VOH260A for standard DIP-8 packages or VOFH260A-X008T for SO-6 surface mount applications, provided pinout compatibility and performance parameters align with system requirements.
