Overview
The VOT8123AB 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 an off-state voltage of 800V. The device supports a maximum RMS on-state current of 100mA and operates within a temperature range of -40°C to +110°C. Packaged in a 6-SMD surface-mount format, it utilizes a typical forward voltage of 1.2V and requires a maximum LED trigger current of 10mA for activation.
Feature Summary
- Non-zero crossing output configuration for immediate load control
- High insulation voltage rating of 5000Vrms for safety isolation
- Robust static dV/dt immunity to prevent false triggering
- Surface-mount 6-pin package for compact PCB integration
Applications
- Solid-state relay (SSR) modules
- AC motor speed control circuits
- Industrial process control systems
- Power supply feedback loops
Procurement Notes
Verify the specific suffix designation when ordering, as packaging options such as tube or tape-and-reel may vary by distributor. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly line specifications. Ensure the selected variant matches the required lead time constraints for production scheduling.
Selection Notes
Select this component for applications requiring immediate AC load switching without zero-crossing delay. Compare the 100mA RMS current rating against peak load requirements to ensure adequate headroom. Evaluate the 6-SMD footprint compatibility with existing board layouts and verify thermal management needs for the operating temperature range.
Part Context
This part belongs to the VOT8121/8123 series of phototriac optocouplers designed for general-purpose AC switching. It shares architectural similarities with other Vishay optoisolators but distinguishes itself through its specific non-zero crossing characteristic and 6-pin SMD form factor, catering to modern high-density electronic designs.
Replacement Considerations
Direct substitutes include the VOT8123AB-V and VOT8123AB-T variants, which share identical electrical characteristics but differ in packaging format. Verify pinout compatibility and mounting style before substitution to ensure mechanical fit.
