VOT8024AM-T2

Overview

The VOT8024AM-T2 is a single-channel phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an integrated zero-crossing detection circuit for low electromagnetic interference switching. The device provides 3750Vrms isolation voltage and supports an off-state repetitive peak voltage of 800V. It operates with a maximum RMS on-state current of 100mA and a typical forward voltage of 1.2V. The component is housed in a compact SOP-4 surface-mount package, suitable for automated assembly processes.

Feature Summary

• Integrated zero-crossing circuitry ensures switching occurs near the AC line voltage zero point to minimize electrical noise.
• High isolation capability with 3750Vrms dielectric strength between input and output sections.
• Compact SOP-4 surface-mount package design facilitates space-constrained PCB layouts.

Applications

• Solid-state relays requiring low-noise AC load switching
• Motor control circuits for small appliances
• Industrial automation systems with isolated AC interface requirements

Procurement Notes

Verify the specific suffix 'T2' corresponds to the reel packaging configuration required for your production line. Confirm that the zero-crossing variant aligns with your system's timing constraints, as non-zero-crossing alternatives exist within the same family. Ensure compatibility with your automated placement equipment regarding the SOP-4 footprint dimensions.

Selection Notes

Select this component when precise phase-angle control is not required, but low electromagnetic interference is critical. The internal zero-crossing logic simplifies driver design by handling turn-on timing automatically. Compare against non-zero-crossing models if immediate turn-on upon signal assertion is necessary for specific application dynamics.

Part Context

This part belongs to the VOT8024AM series of Vishay's high-performance optocouplers. It shares the same physical footprint and basic electrical characteristics as the VOT8024AM-VT, differing primarily in the tape-and-reel packaging format indicated by the T2 suffix. It complements the VOT8121AM series, which offers similar isolation but without the zero-crossing feature.

Replacement Considerations

The VOT8024AM-VT serves as a direct functional substitute with identical electrical specifications, differing only in packaging type. For applications requiring immediate turn-on without zero-crossing delay, consider the VOT8121AM series. Verify pinout compatibility before substituting with other generic triac optocouplers.
