Overview
The VOT8025AB-VT1 is a single-channel Triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates a GaAs infrared LED with a photosensitive zero-crossing TRIAC in a compact SMD-6 package. Key electrical parameters include an isolation voltage of 5300 Vrms, a peak repetitive off-state voltage (VDRM) of 800 V, and a maximum continuous on-state current of 100 mA. The device features a typical forward voltage of 1.2 V at a maximum forward current of 20 mA. It operates within a temperature range of -40°C to +110°C.
Feature Summary
- Integrated zero-crossing circuitry for low electromagnetic interference switching
- High input sensitivity with raised trigger current capability
- Ultra-fast switching times for efficient signal transmission
Applications
- Solid-state relay control circuits
- Motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix VT1 to confirm the tape-and-reel packaging format and quantity per reel. Ensure the component matches the SMD-6 footprint requirements for your PCB layout. Confirm RoHS compliance status through the official datasheet before integration into regulated assemblies.
Selection Notes
Select this component when high isolation voltage and zero-crossing functionality are required in a surface-mount form factor. Compare the 100 mA load capacity against system demands. Consider the -40°C to +110°C operating range for environmental suitability. Verify pinout compatibility with existing designs if replacing similar Vishay models.
Part Context
This part belongs to the VOT8025A series of Triac output optocouplers. The series is designed for applications requiring reliable isolation between control and power stages. The VOT8025AB variant specifically denotes the zero-crossing feature and specific electrical characteristics defined in the Vishay product specification.
Replacement Considerations
Direct substitutes may include other Vishay VOT8025 variants with compatible pinouts and electrical ratings. Verify that any replacement maintains the zero-crossing function and 5300 Vrms isolation rating. Check package dimensions to ensure mechanical fit.
