Overview
The VOT8125AB-VT2 is a zero-crossing triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a GaAs infrared LED optically coupled to a photosensitive TRIAC in a DIP-6 package. Key electrical specifications include an isolation voltage of 5300Vrms, an off-state output voltage (VDRM) of 800V, and a maximum continuous on-state current (It RMS) of 100 mA. The device operates with a typical forward voltage (Vf) of 1.2V and a maximum DC forward current (If) of 20 mA. It exhibits high input sensitivity with a maximum LED trigger current (Ift) of 5 mA and a minimum static dV/dt rating of 1000 V/µs. The component supports a wide operating temperature range from -40°C to +110°C.
Feature Summary
- Integrated zero-crossing detection circuitry for low electromagnetic interference switching
- High isolation voltage capability of 5300Vrms between input and output
- High static dV/dt immunity rated at 1000 V/µs
- High input sensitivity requiring a maximum trigger current of 5 mA
Applications
- Solid state relays
- Motor control circuits
- Lighting control systems
Procurement Notes
Verify the specific suffix VT2 against the official Vishay datasheet to confirm packaging type and tape-and-reel specifications. Ensure the selected variant matches the required DIP-6 package configuration. Cross-reference certification marks such as UL, VDE, and CQC with the latest product data sheet to confirm compliance with regional safety standards. Confirm RoHS3 status and moisture sensitivity level requirements prior to procurement.
Selection Notes
Select this component when zero-crossing functionality is required to minimize electrical noise during AC load switching. The 100 mA RMS current rating suits low-power applications, while the 800 V blocking voltage handles standard line voltages. Consider the 5 mA trigger current requirement for driver interface compatibility. The DIP-6 package facilitates through-hole mounting in industrial enclosures.
Part Context
This part belongs to the VOT8125A family of optotriacs, which includes variants like VOT8125AD and VOT8125AG. These devices share the same core architecture of a GaAs IR LED coupled to a photosensitive TRIAC. The family is designed for general-purpose AC switching applications requiring galvanic isolation. Variants typically differ in packaging or specific regulatory approvals rather than core electrical performance.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers.
