Overview
The VOT8123AB-T2 is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a non-zero-crossing output with an isolation voltage of 5000 Vrms and a maximum repetitive peak off-state voltage (VDRM) of 800 V. The device operates in a surface-mount SMD-6 package, supporting a continuous RMS output current of 100 mA. Key electrical parameters include a typical holding current of 400 µA, a maximum DC forward current of 20 mA, and a minimum static dV/dt rating of 1 kV/µs. It functions within a temperature range of -40°C to +110°C.
Feature Summary
- High isolation voltage capability of 5000 Vrms for robust circuit protection
- Non-zero-crossing output design suitable for phase control applications
- High static dV/dt immunity rated at a minimum of 1 kV/µs
- Low input trigger current requirement for efficient drive compatibility
Applications
- Solid-state relay circuits requiring high isolation
- AC motor speed control systems
- Industrial process control automation
- Power supply feedback isolation loops
Procurement Notes
Verify the specific suffix T2 against the official Vishay datasheet to confirm the reel packaging configuration and tape dimensions. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when non-zero-crossing triac triggering is required for precise AC power control. The 800 V VDRM rating supports standard mains voltage applications. Consider the 100 mA RMS output current limit for load sizing. The SMD-6 package facilitates automated surface-mount assembly processes while maintaining high isolation standards.
Part Context
This device belongs to the VOT8123 series of Triac and SCR output optocouplers from Vishay. It is designed for applications demanding high reliability and electrical isolation. The series offers various packaging options including DIP and SMD configurations to suit different manufacturing needs.
Replacement Considerations
Consult the official Vishay substitution guide for verified alternatives. Direct replacements must match the 5000 Vrms isolation, 800 V VDRM, and SMD-6 package constraints.
