Overview
The VOT8125AB-T2 is a Triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a GaAs infrared LED optically coupled to a photosensitive TRIAC in a 6-SMD surface-mount package. Key electrical specifications include a 5000Vrms isolation voltage, 800V breakover voltage, and 100mA RMS on-state current. The device operates within a temperature range of -55°C to 110°C and lacks zero-crossing circuitry.
Feature Summary
- Provides high-voltage isolation between input and output circuits using an infrared LED and photosensitive TRIAC structure.
- Designed for surface-mount assembly in a compact 6-SMD package suitable for automated manufacturing processes.
- Capable of switching AC loads with an 800V breakover voltage rating.
Applications
- Solid-state relay (SSR) modules
- Motor control circuits
- Lighting control systems
Procurement Notes
Verify the specific suffix T2 against the official datasheet to confirm the 6-SMD package configuration and tape-and-reel packaging format. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding alternative detector chip sources or bond wire diameter modifications before finalizing procurement orders.
Selection Notes
Select this component when a non-zero-crossing Triac output is required for phase-angle control applications. The 5000Vrms isolation rating supports high-noise industrial environments. Compare the 100mA RMS current capability against load requirements and ensure the 6-SMD footprint fits the PCB layout constraints compared to DIP alternatives.
Part Context
This part belongs to the VOT8125A family of Triac output optocouplers. It shares functional similarities with other Vishay optoisolators but is distinguished by its specific SMD packaging and non-zero-crossing characteristics. The series includes variants such as VOT8125AD and VOT8125AG, which may differ in package type or certification.
Replacement Considerations
Officially documented alternative sources include the VOT8125AB-V and VOT8125AB-VT. Verify pinout compatibility and package dimensions when substituting these variants to ensure mechanical fit and electrical equivalence in the design.
