Overview
The VOT8123AB-VT2 is a Triac output optoisolator from Vishay Semiconductor Opto Division. It features a non-zero crossing triac output with an isolation voltage of 5000Vrms and a peak repetitive off-state voltage (VDRM) of 800V. The device offers high static dV/dt immunity of 1000 V/µs and low input trigger current (IFT) of 10 mA, supporting an on-state RMS current of 100 mA. Packaged in a compact 6-SMD surface-mount format, it operates within a temperature range of -55°C to 110°C.
Feature Summary
- Non-zero crossing triac output for precise phase control applications
- High static dV/dt immunity rated at 1000 V/µs
- Low input trigger current sensitivity of 10 mA
- Robust isolation capability with 5000Vrms insulation voltage
Applications
- Solid state relays requiring fast switching
- Motor control circuits
- Lighting dimmer systems
- Heater control modules
Procurement Notes
Verify the specific suffix VT2 indicates tape and reel packaging when ordering. Confirm that the 5000Vrms isolation rating meets your safety certification requirements. Ensure the 800V VDRM is sufficient for your line voltage application. Check for RoHS compliance status as per the latest datasheet revision.
Selection Notes
Select this component when non-zero crossing switching is required for resistive or inductive loads. The 100 mA on-state current suits low-power AC loads. Consider the 6-SMD package for space-constrained PCB designs. Verify thermal management needs for continuous operation near the 110°C upper limit.
Part Context
This part belongs to the VOT8123 series of Triac output optocouplers. It shares functional similarities with the VOT8121 but differs in package type and specific electrical ratings. The series is designed for general-purpose AC load switching where galvanic isolation is critical.
Replacement Considerations
Check VOT8123AB-T2 for identical electrical specifications with potential packaging differences. Verify VOT8123AB-VT for leaded vs. surface-mount compatibility. Cross-reference pinouts carefully before substitution.
