Overview
The VOT8121AB-VT2 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a Triac output. 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 surface-mount 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 typical forward voltage of 1.2 V.
Feature Summary
- High-voltage insulation capability with 5300Vrms isolation rating for safe signal transmission between isolated circuits.
- Robust noise immunity characterized by a high static dV/dt rating to prevent false triggering in noisy environments.
- Wide operating temperature range suitable for demanding industrial and commercial applications.
Applications
- Solid-state relay driver circuits
- Industrial motor control systems
- Power supply feedback loops
Procurement Notes
Verify the specific suffix VT2 against the official Vishay datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS3 directives and check for any recent Product Change Notifications regarding manufacturing sources or bond wire diameter changes before finalizing procurement.
Selection Notes
Select this component when high isolation voltage and fast switching are required for AC load control. Compare the 100 mA RMS current limit against load requirements. Consider the 4-SMD footprint for PCB layout constraints and verify that the non-zero-crossing output aligns with the application's phase-control needs.
Part Context
This part belongs to the VOT8121 series of Triac output optocouplers from Vishay. It shares core characteristics with variants like VOT8121AB-T3 and VOT8121AM-VT, differing primarily in packaging and isolation ratings. The series is designed for general-purpose AC switching and isolation tasks.
Replacement Considerations
Direct substitutes include VOT8121AB-T3 and VOT8121AB-VT1. Verify pinout compatibility and isolation voltage ratings when cross-referencing with other manufacturers' Triac output optocouplers.
FAQ
Does the VOT8121AB-VT2 include a zero-crossing detection circuit?
No, the VOT8121AB-VT2 does not feature a zero-crossing circuit; it is designed for random-phase triggering applications.
What is the maximum RMS on-state current for this device?
The maximum RMS on-state current (It(RMS)) is 100 mA.
