Overview
The VOT8125AB-V is a single-channel Triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a non-zero crossing design with an isolation voltage of 5000Vrms and a peak repetitive off-state voltage (Vdrm) of 800V. The device utilizes a surface-mount SMD6 package, supporting a maximum RMS on-state current of 100mA and a DC forward current of 50mA. It operates within a temperature range of -55°C to +110°C and includes no zero-crossing circuitry.
Feature Summary
- Non-zero crossing Triac output configuration for precise phase control applications
- High isolation voltage rating of 5000Vrms ensuring robust electrical safety
- Surface-mount SMD6 packaging optimized for automated assembly processes
Applications
- Solid state relays requiring high isolation
- Motor control circuits for AC loads
- Industrial process control systems
Procurement Notes
Verify the specific suffix 'V' indicates the correct tape-and-reel packaging format as defined in the official datasheet. Confirm that the 5000Vrms isolation rating aligns with your system's safety requirements. Ensure the non-zero crossing characteristic is suitable for your load type, as it differs from zero-crossing variants. Check for RoHS3 compliance status in the latest documentation.
Selection Notes
Select this component when non-zero crossing operation is required for immediate triac triggering upon input signal application. The 800V Vdrm rating suits medium-voltage AC loads. Compare against the DIP-6 VOT8125AB if through-hole mounting is preferred. Ensure the 100mA RMS current capacity meets the load requirements without exceeding thermal limits.
Part Context
This part belongs to the VOT8121/8125 series of Triac output optocouplers. It shares functional similarities with the VOT8121AB-T3 but offers higher isolation voltage (5000Vrms vs 5300Vrms) and different packaging. The series is designed for general-purpose AC switching applications where galvanic isolation is critical.
Replacement Considerations
The VOT8125AB is the through-hole equivalent. Verify pinout compatibility before substitution. No direct drop-in replacement is confirmed in public data; consult Vishay for qualified alternatives.
