Overview
The VOT8121AB-T1 is a single-channel optoisolator featuring a Triac output, manufactured by Vishay Semiconductor Opto Division. It provides an isolation voltage of 5300Vrms and supports a maximum RMS on-state current of 100 mA. The device operates within a temperature range of -55°C to 110°C and utilizes a 4-SMD gull wing package. Key electrical parameters include a peak repetitive off-state voltage of 800 V, a minimum static dV/dt of 1 kV/µs, and a maximum DC forward current of 50 mA.
Feature Summary
- High isolation voltage capability for robust circuit protection
- Non-zero crossing design suitable for phase control applications
- Surface-mount construction for automated assembly
Applications
- AC load control in industrial systems
- Consumer appliance motor drives
- Solid-state relay interfaces
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm pinout and packaging variations. Ensure compliance with RoHS3 standards and check for recent Product Change Notifications regarding manufacturing sources or bond wire specifications before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and non-zero switching are required for AC power control. Compare the 5300Vrms rating against system insulation requirements and ensure the 100 mA output current meets load demands. Verify thermal management needs for the specified operating temperature range.
Part Context
This part belongs to the VOT8121 family of phototriac optocouplers. It shares core functional characteristics with variants like the VOT8121AM-VT but differs in isolation voltage ratings and package types. The family is designed for general-purpose AC switching applications requiring galvanic isolation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult official Vishay cross-reference guides for verified alternatives.
