VOT8121AD-V

Overview

The VOT8121AD-V is a single-channel phototriac optoisolator manufactured by Vishay Semiconductor Opto Division. It features an isolation voltage of 5300Vrms and supports a maximum RMS on-state current of 100 mA. The device operates with a forward current up to 50 mA and includes a peak trigger current of 10 mA. It offers a blocking voltage of 800 V and a minimum static dV/dt rating of 1 kV/µs. The component utilizes a 4-DIP package, functions within a temperature range of -55°C to 110°C, and lacks zero-crossing circuitry.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Capable of switching AC loads via integrated triac output structure
• Designed for robust operation in industrial environments with wide thermal tolerance

Applications

• AC power switching control systems
• Solid-state relay driver circuits
• Industrial process control interfaces

Procurement Notes

Verify the specific suffix 'V' indicates the DIP-4 package configuration distinct from SMD variants. Confirm RoHS compliance status and MSL level requirements for assembly processes. Ensure supplier documentation matches the 5300Vrms isolation rating specified for this part number variant.

Selection Notes

Select this component when high isolation voltage and AC load switching are required in a through-hole format. Compare against SOP variants if surface mount space constraints exist. Verify that the absence of zero-crossing detection aligns with the application's phase-control needs.

Part Context

This part belongs to the VOT8121 family of phototriac optocouplers. It shares core electrical characteristics with other package variants like the VOT8121AB-T3 but differs in physical footprint. The AD-V designation specifically denotes the dual-in-line package suitable for standard PCB mounting techniques.
