Overview
The VOT8123AB-VT is a single-channel Triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a compact SMD-6 package and provides an isolation voltage of 5000Vrms. The device supports a peak repetitive off-state voltage (VDRM) of 800V and a maximum RMS on-state current of 100mA. Key electrical specifications include a static dV/dt rating of 1000 V/µs, a typical holding current of 400µA, and a maximum DC forward current of 20mA with a typical forward voltage of 1.2V. It operates without a zero-crossing circuit and functions within a temperature range of -40°C to 110°C.
Feature Summary
- High noise immunity with a static dV/dt rating of 1000 V/µs
- Compact surface-mount design in a 6-pin SMD package
- High input sensitivity allowing for low drive current requirements
- Robust insulation capability rated at 5000Vrms
Applications
- Solid-state relays
- Motor control circuits
- Industrial automation systems
Procurement Notes
Verify the specific suffix 'VT' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 6-SMD footprint matches your PCB layout constraints. Ensure the component meets RoHS3 compliance standards if mandated by your regional regulations. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.
Selection Notes
Select this component when high noise immunity is critical due to its superior static dV/dt performance. The 800V blocking voltage makes it suitable for higher voltage AC loads compared to lower-rated alternatives. The SMD-6 package offers space savings for dense board layouts. Consider the non-zero-crossing feature if phase-angle firing control is required rather than soft switching.
Part Context
This part belongs to the VOT8123 series of Triac output optocouplers from Vishay. It shares functional similarities with the VOT8123AB-VT2 but differs in packaging or reel specifications. The series is designed to replace older DIP packages with modern surface-mount solutions while maintaining high isolation voltages and robust performance in industrial environments.
Replacement Considerations
The VOT8123AB-VT2 is a related variant within the same product family. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement maintains the 5000Vrms isolation and 800V VDRM ratings.
