The device provides 5000 Vrms isolation voltage and supports a forward current of 10 mA with a forward voltage of 1.38 V. Key timing parameters include a rise time of 23 ns and a fall time of 10 ns. It withstands a reverse voltage of 5 V and delivers an output current of 50 mA. Power dissipation is rated at 125 mW, with an operating temperature range from -40°C to +110°C. The component is housed in an 8-pin DIP package.

Feature Summary

• High-speed signal transmission capability supporting 10 Mb/s data rates for efficient digital communication.
• Robust electrical isolation provided by 5000 Vrms insulation voltage between input and output circuits.
• Open-drain output configuration allows flexible interfacing with various logic families and pull-up requirements.

Applications

• Digital isolation in high-speed communication interfaces
• Signal coupling in industrial control systems
• Noise immunity enhancement in microcontroller circuits

Procurement Notes

Verify the specific suffix X006 confirms the tube packaging format, as other suffixes indicate different packing methods like tape and reel or SMD variants. Ensure the order matches the required DIP-8 through-hole configuration. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement decisions for regulatory adherence.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust common-mode transient immunity. The open-drain output necessitates external pull-up resistors, which must be chosen based on the target logic voltage levels and desired switching speed. Consider the 10 mA forward current requirement for drive circuit design and ensure the thermal environment stays within the specified -40°C to +110°C operational range.

Part Context

This part belongs to Vishay's high-speed optocoupler family, designed for applications demanding fast signal transfer across isolation barriers. It complements dual-channel variants like the VOH263A and offers higher speed than standard transistor-output optocouplers. The series is engineered for reliable performance in noisy environments where electrical safety and signal integrity are critical.

Replacement Considerations

Direct substitutes may include other 10 Mb/s single-channel open-drain optocouplers in DIP-8 packages. Verify pinout compatibility and electrical specifications such as CMTI and propagation delay. Cross-reference with Vishay's internal equivalents or industry-standard alternatives ensuring identical isolation voltage and package dimensions.
