VOT8121AB-T

Overview

The VOT8121AB-T is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a Triac output. It provides an isolation voltage of 5300Vrms and supports a maximum RMS on-state current of 100 mA. The device operates within a temperature range of -55°C to +110°C and utilizes a 4-SMD gull-wing package. Key electrical parameters include a forward voltage of 1.2V typical, a DC forward current maximum of 50 mA, and a peak trigger current of 10 mA. It offers a static dV/dt rating of 1kV/µs minimum and a blocking voltage of 800 V.

Feature Summary

High-voltage insulation capability with 5300Vrms isolation barrier
Robust noise immunity characterized by a minimum static dV/dt rating of 1kV/µs
Wide operating temperature range suitable for demanding industrial environments

Applications

Solid-state relay circuits requiring high isolation
Industrial motor control systems
Power supply feedback loops

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm package type and certification status. Ensure compatibility with surface-mount assembly processes. Confirm RoHS compliance and moisture sensitivity level requirements for your manufacturing line. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement specifications.

Selection Notes

Select this component when high isolation voltage and fast switching are required in a compact surface-mount form factor. Consider the 100 mA load capacity and 800 V blocking voltage for appropriate circuit design. Evaluate thermal management needs given the wide operating temperature range. Compare alternative packages if board space constraints differ from the 4-SMD configuration.

Part Context

This component belongs to the VOT8121 series of Triac output optocouplers. It shares functional similarities with variants like the VOT8121AM-VT but differs in isolation voltage ratings and packaging. The series is designed for general-purpose AC load switching applications where electrical isolation between control and power sides is critical.
