Overview
The VOT8125AD is a triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It consists of a Gallium Arsenide infrared LED optically coupled to a photosensitive TRIAC, packaged in a 6-DIP configuration. The device provides an isolation rating of 5000Vrms and supports up to 100 mA on-state current with high static dV/dt capability of 1000 V/μs. It features high input sensitivity with a forward trigger current (IFT) of 5 mA.
Feature Summary
- High voltage isolation capability for safe circuit separation
- High static dV/dt resistance to prevent false triggering
- High input sensitivity for efficient drive requirements
Applications
- High-voltage isolation applications
- Solid-state relay interfaces
- Motor control circuits
Procurement Notes
Verify the specific suffix designation against official Vishay documentation to confirm package type and lead-free status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet revision to confirm electrical specifications match system requirements.
Selection Notes
Select this component when high isolation voltage and fast switching characteristics are required. The high dV/dt rating makes it suitable for noisy environments where false triggering must be minimized. Verify that the 100 mA on-state current meets the load requirements and that the DIP-6 package fits the available PCB space constraints.
Part Context
This component belongs to the VOT8125A family, which includes variants such as VOT8125AB and VOT8125AG. These devices share the same core architecture of a GaAs IRLED coupled to a phototriac. The specific AD suffix denotes particular manufacturing or packaging variations within this series, distinguished by their 6-DIP package form factor.
Replacement Considerations
Direct substitutes may include other Vishay VOT8125A series variants like VOT8125AB or VOT8125AG if pinout and electrical ratings are compatible. External replacements require matching the 5000Vrms isolation, 800V blocking voltage, and 100 mA current handling capabilities while maintaining the DIP-6 footprint.
FAQ
What is the maximum isolation voltage rating?
The VOT8125AD provides a 5000Vrms isolation rating between the input LED and output TRIAC.
What is the static dV/dt rating?
The device features a high static dV/dt rating of 1000 V/μs to resist false triggering.
