Overview
The VOT8121AB-VT3 is a single-channel Triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a 5300Vrms isolation voltage and an 800V off-state voltage capability. The device operates within a temperature range of -55°C to 110°C and utilizes a 4-SMD surface-mount package. Key electrical specifications include a maximum RMS on-state current of 100 mA, a typical holding current of 400µA, and a minimum static dV/dt of 1kV/µs. The input LED has a maximum forward current of 50 mA and a typical forward voltage of 1.2V.
Feature Summary
- Provides high-voltage isolation between input and output circuits for safe signal transmission.
- Capable of switching AC loads with an 800V off-state voltage rating.
- Designed for robust performance in industrial environments with wide operating temperature ranges.
Applications
- Solid-state relays
- Motor control circuits
- Industrial process control systems
Procurement Notes
Verify the specific suffix VT3 against the manufacturer's official datasheet to confirm package type and tape-and-reel configuration. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding manufacturing sources or bond wire specifications before finalizing procurement.
Selection Notes
Select this component when high isolation voltage and Triac output are required for AC load switching. Compare the 5300Vrms isolation rating and 100mA current handling against system requirements. Consider the 4-SMD footprint constraints and ensure the thermal management supports the specified operating temperature range.
Part Context
This part belongs to the VOT8121 family of Triac output optocouplers from Vishay. It shares core functional characteristics with variants like VOT8121AB-T3 but differs in packaging and reel specifications. The family is designed for general-purpose AC switching applications requiring galvanic isolation.
Replacement Considerations
Direct substitutes may include other Vishay VOT8121 series variants such as VOT8121AB-T3, provided the package and reel format match the assembly requirements. Verify pinout compatibility and electrical ratings before substitution.
FAQ
Does the VOT8121AB-VT3 include an internal zero-crossing circuit?
No, the VOT8121AB-VT3 does not feature an internal zero-crossing circuit; it is a standard Triac output optoisolator.
What is the maximum RMS on-state current for this device?
The maximum RMS on-state current (It(RMS)) for the VOT8121AB-VT3 is 100 mA.
