Overview
The VOT8024AB-VT1 is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates a Gallium Arsenide infrared LED optically coupled to a photosensitive zero-crossing TRIAC, housed in a surface-mount SMD-4 package. Key electrical specifications include an isolation voltage of 5300 Vrms, a maximum forward current (If) of 50 mA, and a forward voltage (Vf) of 1.2 V. The device supports a peak repetitive off-state voltage (VDRM) of 800 V and operates within a temperature range of -55°C to +110°C. It features a zero-crossing circuit with a turn-on voltage threshold of 5 V.
Feature Summary
- Integrates a zero-crossing detection circuit for precise AC load switching
- Provides high insulation capability with 5300 Vrms isolation rating
- Designed for board space efficiency using a compact SMD-4 package
Applications
- Solid state relays
- Motor control circuits
- Lighting control systems
Procurement Notes
Verify the specific suffix VT1 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required VDE certification if applicable to your design. Cross-reference the datasheet revision date to confirm parameter accuracy before finalizing procurement orders.
Selection Notes
Select this component for applications requiring zero-crossing switching to minimize electromagnetic interference. The 800 V blocking voltage suits general AC mains applications. Consider the SMD-4 footprint for density constraints. Verify thermal management requirements against the 250 mW power dissipation limit at elevated ambient temperatures.
Part Context
This part belongs to the VOT8024 series of Triac output optocouplers from Vishay. The series typically includes variants with different packaging options such as DIP or tube configurations. The AB designation specifies the zero-crossing feature and electrical characteristics. The VT1 suffix denotes the reel packaging format for automated assembly processes.
Replacement Considerations
Check for direct substitutes within the same Vishay family that may offer alternative packaging like tubes instead of reels. Verify pinout compatibility and isolation voltage ratings when considering cross-manufacturer replacements.
