VOIH063AT

Overview

The VOIH063AT is a high-speed dual-channel optocoupler manufactured by Vishay Semiconductor Opto Division. It features an open-drain output configuration and operates within a supply voltage range of 2.7V to 5.5V. The device supports data rates up to 10 MBd with a typical rise time of 11 ns and fall time of 2.3 ns. It provides an isolation voltage of 3750 Vrms and a common-mode transient immunity (CMTI) of 15 kV/µs. Packaged in an 8-SOIC housing, it functions reliably across a temperature range of -40°C to +110°C.

Feature Summary

• Dual-channel architecture for simultaneous signal isolation
• High common-mode transient immunity of 15 kV/µs
• Open-drain output interface compatible with standard logic levels

Applications

• Industrial communication bus isolation
• Power supply feedback loops
• Digital isolator replacement in noisy environments

Procurement Notes

Verify the specific suffix 'AT' corresponds to the required tape-and-reel packaging format. Confirm that the 8-SOIC footprint matches the target PCB design constraints. Ensure the input current specifications align with the driving circuit capabilities before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required alongside high-speed digital signaling. The open-drain output necessitates external pull-up resistors for proper logic level translation. Consider the 15 kV/µs CMTI rating for applications involving rapid switching transients near sensitive control circuits.

Part Context

This part belongs to Vishay's VOIH series of high-speed optocouplers designed for robust noise immunity. Unlike single-channel variants, the VOIH063AT integrates two independent channels in one package, optimizing board space while maintaining electrical isolation standards for modern industrial electronics.

Replacement Considerations

Check datasheets for equivalent dual-channel devices from other manufacturers ensuring matching 10 MBd speed and 3750 Vrms isolation ratings.
