VOT8025AD-V

Overview

The VOT8025AD-V is a phototriac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a zero-crossing detection circuit and high dV/dt capability, designed for low input current operation. The device utilizes a 6-DIP package with 5 leads (DIP5) and offers an isolation voltage of 5300Vrms. It supports a repetitive peak off-state voltage (Vdrm) of 800V and provides a maximum on-state current of 100mA. This component is engineered for reliable signal transmission across isolated circuits while minimizing electromagnetic interference through precise switching timing.

Feature Summary

• Integrated zero-crossing detection for reduced electrical noise
• High dV/dt immunity to prevent false triggering
• Low input current requirement for efficient drive
• Robust 5300Vrms isolation barrier

Applications

• Solid-state relay driver circuits
• AC power switching control systems
• Industrial motor control interfaces
• Lighting dimmer applications

Procurement Notes

Verify the specific suffix 'V' indicates the correct tape-and-reel or bulk packaging configuration as defined in the official datasheet. Confirm that the DIP5 lead count aligns with your PCB footprint requirements. Ensure the manufacturer is identified as Vishay Semiconductor Opto Division to avoid counterfeit components. Cross-reference the part number against the latest revision history to confirm compatibility with your design specifications.

Selection Notes

Select this component when zero-crossing switching is required to minimize inrush currents and EMI in AC loads. The 800V rating suits standard mains voltage applications. Consider the 100mA on-state current limit; it functions primarily as a driver rather than a direct load switch for high-power devices. Verify thermal management needs based on the hold current characteristics if operating in continuous conduction modes.

Part Context

This device belongs to the VOT8025A family, which includes variants like VOT8025AD. The 'V' suffix typically denotes specific packaging or handling options within Vishay's product line. It is distinct from non-zero-crossing triac outputs. The DIP5 package distinguishes it from standard 6-lead DIP optocouplers by integrating the zero-crossing detector within the same silicon die or package structure.

Replacement Considerations

Direct substitutes include other Vishay VOT8025 series variants such as VOT8025AD. Check pinout compatibility and isolation voltage ratings before substituting with competitors. Ensure the replacement also features zero-crossing detection and similar dV/dt ratings to maintain system performance.
