Overview
The VOT8025AB-VT is a Triac and SCR output optoisolator from Vishay Semiconductor Opto Division. It features a GaAs IR LED optically coupled to a photosensitive zero-crossing TRIAC in an SMD-6 package. Key electrical parameters include an isolation voltage of 5300Vrms, a peak repetitive off-state voltage (VDRM) of 800V, and a maximum continuous output current of 100mA. The device operates with a forward current of 20mA and has a minimum operating temperature of -40°C.
Feature Summary
- Integrated zero-crossing circuit for precise switching timing
- High static dV/dt immunity rated at 1000 V/μs
- High input sensitivity requiring only 5 mA trigger current
Applications
- Solid state relays
- Motor control circuits
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix (VT) against the manufacturer's official datasheet to confirm tape and reel packaging specifications. Ensure that the required isolation voltage and on-state current ratings align with the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and zero-crossing functionality are required for AC load control. The SMD-6 package suits space-constrained designs. Verify thermal dissipation requirements as the power dissipation is limited to 250 mW.
Part Context
This part belongs to the VOT8025A family, which includes variants like VOT8025AD and VOT8025AG. These devices share similar functional characteristics but may differ in packaging or specific electrical tolerances defined by Vishay.
Replacement Considerations
Potential substitutes within the same family include VOT8025AD and VOT8025AG. Cross-reference these part numbers with official Vishay documentation to ensure compatibility regarding pinout and electrical ratings.
