Overview
The VOT8026AB is a zero-crossing TRIAC output optocoupler from Vishay Semiconductor Opto Division. It integrates a GaAs infrared LED with a photosensitive TRIAC in a DIP-6 package. Key electrical parameters include a maximum repetitive peak off-state voltage (Vdrm) of 800V and an RMS on-state current (It(rms)) of 100mA. The device features an isolation voltage of 5300Vrms. Trigger characteristics specify a maximum LED trigger current (Ift) of 5mA and a typical hold current (Ih) of 400µA.
Feature Summary
- Integrated zero-crossing detection circuitry for TRIAC triggering
- High isolation voltage capability between input and output circuits
- Optically coupled interface using GaAs IR LED and photosensitive TRIAC
Applications
- Solid-state relay control
- AC motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix against procurement requirements, as variants such as -V indicate surface mount packaging while standard designations may imply through-hole configurations. Confirm that the 800V rating aligns with the target AC line voltage. Ensure the 100mA output current capacity meets the load requirements of the controlled TRIAC or SCR gate drive circuit.
Selection Notes
Select this component when precise zero-crossing switching is required to minimize electromagnetic interference and inrush currents in AC power applications. The 800V blocking voltage suits standard mains voltage levels. Consider the DIP-6 package constraints for PCB layout. Verify thermal management needs if operating near the 100mA continuous current limit.
Part Context
This part belongs to the VOT8026A family of optotriacs designed for AC power switching. The series includes variants like VOT8026AD and VOT8026AG, which share similar functional architectures but may differ in voltage ratings or packaging. These devices are engineered for reliable isolation in industrial and consumer AC control environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official cross-reference guides or manufacturer recommendations for equivalent components with matching voltage and current specifications.
