Overview
The VOT8024AD-V is a Triac and SCR output optocoupler featuring a PhotoTRIAC output with an integrated zero-crossing circuit. It provides high-input sensitivity and supports a maximum DC forward current of 50 mA with a typical forward voltage of 1.2 V. The device offers an on-state RMS current of 100 mA and a peak off-state blocking voltage of 800 V. Insulation voltage is rated at 3750 Vrms. Operating temperature ranges from -55°C to +110°C, housed in a through-hole DIP-4 package.
Feature Summary
- Integrated zero-crossing detection circuit for low EMI switching
- High input sensitivity with low trigger current requirements
- Robust insulation isolation between input and output circuits
Applications
- Isolating low-voltage logic from AC mains lines
- Controlling resistive, inductive, or capacitive loads
- Motor control applications requiring phase-independent switching
Procurement Notes
Verify the specific suffix 'V' indicates RoHS compliance and halogen-free status as per Vishay documentation. Confirm the DIP-4 package dimensions match your PCB footprint requirements. Ensure the 3750 Vrms insulation rating meets your safety isolation standards for the target application environment.
Selection Notes
Select this component when zero-crossing switching is required to minimize electromagnetic interference. The 100 mA on-state current suits light to moderate load control. Compare against non-zero-crossing variants if precise phase-angle control is needed instead of soft-start switching characteristics.
Part Context
This part belongs to the VOT8024Ax series of PhotoTRIAC optocouplers. It shares functional similarities with the VOT8024AG-V but differs in packaging and insulation ratings. The series is designed for general-purpose AC load control where electrical isolation and noise reduction are critical design parameters.
Replacement Considerations
Public confirmed substitutes include VOT8024AG-V for similar functionality with different insulation ratings. Verify pinout compatibility and thermal management requirements before swapping packages.
