Overview
The VOT8025AB is a Triac output optocoupler featuring a zero-crossing circuit, packaged in a compact SMD-6 configuration. It provides high isolation voltage of 5300 VRMS and supports a maximum repetitive peak off-state voltage (Vdrm) of 800 V. The device delivers a maximum continuous on-state current of 100 mA with a minimum operating temperature of -40°C and a maximum of 125°C. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.2 V, and power dissipation of 250 mW.
Feature Summary
- Integrated zero-crossing detection circuit for reduced electromagnetic interference
- High static dV/dt rating of 1000 V/μs for noise immunity
- Low trigger current of 5 mA compatible with digital logic interfaces
- High isolation distance on output for wider PCB pad spacing
Applications
- Control of resistive, inductive, and capacitive loads in home appliances
- Isolation control for motors, solenoids, and relays in industrial equipment
- Line voltage isolation for 120 VAC, 240 VAC, and 380 VAC systems
- Gate driving for large current thyristors or TRIACs
Procurement Notes
Verify the specific suffix (e.g., T, VT, V) to confirm tape-and-reel packaging versus tube quantities. Confirm RoHS compliance status as per the latest Vishay datasheet revision. Ensure the selected variant matches the required zero-crossing functionality for the application design.
Selection Notes
Select this component when phase-independent switching via zero-crossing is required to minimize EMI. The 800 V Vdrm offers safety margin for single-phase applications while maintaining adequacy for three-phase systems. Consider the 100 mA RMS current limit for load sizing and verify thermal dissipation requirements within the SMD-6 package constraints.
Part Context
Part of the VOT8025A series, which includes variants like VOT8025AD and VOT8025AG. These devices utilize a GaAs infrared LED optically coupled to a photosensitive TRIAC. The series expands Vishay's portfolio of compact DIP-6 and SMD-6 optoisolators designed for high stability and noise isolation in AC power control applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements by matching pinout, isolation voltage, and current ratings against the original datasheet specifications.
