Overview
The VOT8024AG-V is a Triac and SCR Output Optocoupler manufactured by Vishay Semiconductors. It features a PhotoTRIAC output with an integrated zero-crossing circuit, designed for high-voltage switching applications. The device operates in a DIP-4 through-hole package with a 400mil lead spacing. Key electrical parameters include a maximum off-state voltage (VDRM) of 800 V, an isolation voltage of 5300 Vrms, and a forward current (If) rating of 50 mA. The component supports a wide operating temperature range from -55°C to +110°C and has a typical forward voltage (Vf) of 1.2 V.
Feature Summary
- Integrated zero-crossing detection circuitry for reduced electromagnetic interference during AC switching
- High insulation capability with 5300 Vrms isolation voltage between input and output
- Robust 800 V peak off-state blocking voltage for high-voltage load control
- DIP-4 package configuration suitable for standard through-hole mounting processes
Applications
- Solid-state relays requiring zero-crossing switching capabilities
- AC motor speed control circuits
- Lighting dimmer applications
- General-purpose AC power switching interfaces
Procurement Notes
Verify the specific suffix 'V' indicates tube packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the DIP-4 footprint matches the target PCB layout design. Validate that the 5300 Vrms isolation rating meets the safety requirements of the end application environment.
Selection Notes
Select this component for applications requiring precise zero-crossing timing to minimize noise. The 800 V blocking voltage makes it suitable for direct mains voltage interfacing. Consider the 50 mA forward current requirement for driver circuit design. The through-hole package is appropriate for high-reliability or high-power density assemblies where surface mount options are insufficient.
Part Context
This part belongs to the Vishay VOT8024Ax series of PhotoTRIAC optocouplers. It is distinct from non-zero-crossing variants like the VOT8123AG. The device utilizes a GaAs infrared LED coupled to a silicon photoTRIAC. It is designed for industrial and consumer AC control systems requiring galvanic isolation.
Replacement Considerations
Check for equivalent parts within the Vishay VOT8024A family. Verify pinout compatibility before substituting with other manufacturers' zero-crossing TRIAC optocouplers. Ensure replacement devices match the 800 V and 5300 Vrms ratings.
