Overview
The VOT8125AB-VT is a non-zero-crossing triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a gallium arsenide infrared LED optically coupled to a photosensitive TRIAC in a 6-SMD surface-mount package. Key electrical specifications include a 5000Vrms isolation voltage, an 800V blocking voltage (VDRM), and a maximum RMS on-state current of 100 mA. The device operates within a temperature range of -40°C to +110°C, has a typical forward voltage of 1.2V, and supports a minimum static dV/dt of 1kV/µs.
Feature Summary
- Non-zero-crossing triac output design for precise phase control applications
- High isolation capability with 5000Vrms input-to-output voltage rating
- Robust noise immunity featuring high static dV/dt of 1000 V/µs
- High input sensitivity allowing efficient drive with low trigger current
Applications
- Solid-state relays requiring fast switching without zero-crossing delay
- AC motor speed control circuits
- Lighting dimmer systems
- Heater control modules
Procurement Notes
Verify the specific suffix VT indicates tape-and-reel packaging when ordering. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the 6-SMD footprint matches the target PCB layout. Check for any recent Product Change Notifications regarding bond wire diameter or assembly source changes before finalizing procurement plans.
Selection Notes
Select this component when phase-angle control is required rather than zero-crossing switching. The 100 mA output current suits low-power AC loads. Verify that the 5000Vrms isolation meets system safety requirements. Consider the 6-SMD package constraints for thermal management and board space compared to DIP alternatives.
Part Context
This part belongs to the VOT8125A family of non-zero-crossing optotriacs. It shares functional similarities with the VOT8125AB but differs in packaging and specific certification details. The series is designed for general-purpose AC power control where immediate turn-on upon signal application is necessary.
Replacement Considerations
Direct substitutes include other Vishay VOT8125 variants such as VOT8125AB-DIP if through-hole mounting is acceptable. Cross-brand replacements must match the 100 mA current rating, 5000Vrms isolation, and non-zero-crossing behavior.
FAQ
Does the VOT8125AB-VT include a zero-crossing detection circuit?
No, it is a non-zero-crossing device that turns on immediately when triggered.
What is the maximum blocking voltage of the output TRIAC?
The device supports a peak repetitive off-state voltage (VDRM) of 800 V.
