Overview
The VOT8125AB-T is a Triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a 5000Vrms isolation voltage and an 800V blocking voltage. The device operates in a surface-mount SMD-6 package with one channel. Key electrical parameters include a maximum RMS on-state current of 100 mA, a minimum static dV/dt rating of 1kV/µs, and a typical holding current of 400µA. It supports a DC forward current up to 50 mA and functions within a temperature range of -55°C to 110°C.
Feature Summary
- Provides high-voltage isolation for safe signal transmission between circuits
- Features high static dV/dt immunity to prevent false triggering
- Designed for non-zero crossing applications requiring precise control
Applications
- Solid-state relay (SSR) driver circuits
- AC motor control systems
- Industrial process control interfaces
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the supplier provides valid UL, VDE, or cUL certification marks required for safety-critical designs. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component for applications requiring robust isolation and high dV/dt noise immunity. Compare the 100mA on-state current against load requirements to ensure adequate margin. Consider the SMD-6 footprint constraints during PCB layout. Verify that the 5000Vrms isolation rating meets the system's safety clearance and creepage distance standards.
Part Context
This part belongs to the VOT812x series of Optotriacs from Vishay. These devices are engineered for general-purpose AC switching. The series offers various isolation voltages and package options. The VOT8125AB-T specifically targets high-reliability industrial environments where compact size and strong noise rejection are critical.
Replacement Considerations
Check for direct substitutes like the VOT8121AB-T if lower isolation voltage is acceptable. Verify pinout compatibility before swapping with other Vishay Optotriac variants. Ensure replacement parts maintain the same 800V blocking voltage and package type.
