VOH263A-X006

Overview

The VOH263A-X006 is a high-speed dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain output configuration and operates within a temperature range of -40°C to +110°C. Key electrical parameters include a forward current of 20 mA, a forward voltage of 1.38 V, and a reverse voltage of 5 V. The device supports a data rate of 10 MBd with rise and fall times of 11 ns each. It provides an insulation voltage of 5000 Vrms and a common-mode transient immunity of 15 kV/µs. The maximum power dissipation is 85 mW, and the output current capacity is 50 mA.

Feature Summary

• Dual-channel architecture for simultaneous signal isolation
• High common-mode transient immunity of 15 kV/µs
• Open-drain logic output interface
• Through-hole DIP-8 packaging

Applications

• Industrial communication bus isolation
• Signal isolation in noisy environments
• Digital input/output interfacing

Procurement Notes

Verify the specific suffix X006 against official Vishay documentation to confirm tube packaging and RoHS compliance status. Ensure the procurement channel sources genuine components from authorized distributors to avoid counterfeit parts. Cross-reference the manufacturer part number with the distributor catalog to confirm availability and correct pinout configuration before ordering.

Selection Notes

Select this component when dual-channel isolation with high-speed digital signaling is required. The open-drain output necessitates external pull-up resistors for proper logic level translation. Consider the 5000 Vrms insulation rating for safety-critical applications. Verify that the 10 MBd data rate meets the system timing requirements and that the operating temperature range aligns with the environmental conditions.

Part Context

This component belongs to the Vishay high-speed optocoupler family, designed for robust signal transmission across isolated barriers. The VOH263A variant specifically offers dual channels in a standard DIP-8 package, distinguishing it from single-channel counterparts like the VOWH260A. It utilizes LED-to-phototransistor technology optimized for fast switching speeds and high reliability in industrial settings.

Replacement Considerations

Direct substitutes may include other Vishay dual-channel high-speed optocouplers with compatible pinouts and electrical ratings. Verify that any replacement maintains the 10 MBd data rate and 5000 Vrms insulation voltage. Check for identical package dimensions and thermal characteristics to ensure mechanical compatibility.
