Overview
The VOT8123AD is a single-channel Triac output optoisolator 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 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-DIP configuration, it includes a minimum static dV/dt rating of 1kV/µs and requires a maximum LED trigger current of 10mA.
Feature Summary
- Non-zero-crossing Triac output for precise phase control applications
- High common-mode transient immunity with 1kV/µs static dV/dt rating
- Robust electrical isolation rated at 5000Vrms
- Wide operating temperature range suitable for industrial environments
Applications
- Solid-state relays requiring fast switching response
- AC motor speed control circuits
- Industrial process control systems
- Lighting dimmer modules
Procurement Notes
Verify the specific suffix 'AD' corresponds to the 6-DIP package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid UL, cUL, or VDE certification marks for safety-critical implementations. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.
Selection Notes
Select this component when zero-crossing detection is undesirable for phase-angle firing applications. The 800V blocking voltage suits standard AC line voltages. Compare the 100mA current rating against load requirements. Consider the DIP-6 package for through-hole assembly processes. Evaluate the 5000Vrms isolation barrier for circuit safety standards.
Part Context
This part belongs to the VOT812x series of Triac output optocouplers from Vishay. It shares functional similarities with the VOT8123AG but differs in packaging, utilizing a DIP-6 form factor instead of tube packaging variants. The series is designed for general-purpose AC power switching where high reliability and noise immunity are required.
Replacement Considerations
Direct substitutes include other Vishay VOT8123 variants with compatible pinouts. Verify that alternative Triac output optocouplers maintain the 800V VDRM and 5000Vrms isolation ratings. Ensure replacement devices support the same 100mA It(RMS) capability and non-zero-crossing behavior.
