Overview
The VOT8024AB-V is a PhotoTRIAC output optocoupler featuring an integrated zero-crossing detection circuit. It utilizes a GaAs infrared LED optically coupled to a photosensitive TRIAC within a surface-mount SMD-4 package. The device supports a peak off-state voltage of 800 V and provides an isolation voltage of 5300 Vrms. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.2 V, and a power dissipation of 250 mW. It operates within a temperature range of -55°C to +110°C and includes a zero-crossing voltage threshold of 5 V.
Feature Summary
- Integrated zero-crossing detection circuit for noise reduction
- High input sensitivity with low trigger current requirements
- Robust insulation capability for high-voltage isolation
- Surface-mount packaging for space-constrained designs
Applications
- Solid-state relay control circuits
- Motor speed control systems
- Lighting dimmer applications
- AC load switching interfaces
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest documentation to ensure correct package type and compliance status. Confirm that the SMD-4 footprint matches the target PCB layout. Check for RoHS compliance details in the official datasheet before finalizing procurement specifications.
Selection Notes
Select this component when zero-crossing switching is required to minimize electromagnetic interference and inrush currents. Ensure the application voltage does not exceed the 800 V blocking rating. Verify that the SMD-4 package dimensions are compatible with the assembly process and available board space constraints.
Part Context
This part belongs to Vishay's VOT8024Ax series of PhotoTRIAC optocouplers designed for AC power control. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The series is engineered for reliable isolation in industrial and consumer AC control environments.
Replacement Considerations
Direct substitutes may include VOT8024AB or VOT8024AG depending on package preference. Verify pinout compatibility and isolation ratings before substitution. Cross-reference datasheets for thermal and electrical parameter alignment.
