Overview
The VOT8125AD-V is a Triac output optoisolator manufactured by Vishay Semiconductor Opto Division. It features a non-zero crossing phototriac output capable of handling an 800V peak off-state voltage and a 100mA on-state current. The device provides high isolation with a 5000Vrms isolation voltage and a static dV/dt rating of 1000 V/μs. It operates within a temperature range of -40°C to 110°C and is housed in a 6-DIP package with five leads.
Feature Summary
- Non-zero crossing Triac output for phase control applications
- High isolation voltage of 5000Vrms
- High static dV/dt immunity of 1000 V/μs
- High input sensitivity with IFT of 5 mA
Applications
- Solid state relays
- Motor control circuits
- Lighting control systems
Procurement Notes
Verify the specific suffix 'AD' against the official Vishay datasheet to confirm pinout and packaging details, as variations exist within the VOT series. Ensure the procurement source provides the original manufacturer datasheet rather than third-party summaries to validate the 800V rating and DIP-5 lead configuration. Confirm RoHS compliance status directly from the component marking or official documentation before ordering.
Selection Notes
Select this component when non-zero crossing switching is required for AC load control. The high dV/dt rating makes it suitable for noisy environments. Verify that the 100mA on-state current meets the load requirements. The 5000Vrms isolation is appropriate for mains-connected applications. Compare against zero-crossing variants if soft-start functionality is needed instead of immediate switching.
Part Context
This part belongs to the VOT series of Triac output optocouplers from Vishay. These devices are designed for interfacing low-voltage control circuits with high-voltage AC loads. The series typically offers various voltage ratings and package options. The VOT8125AD-V specifically targets applications requiring robust isolation and fast switching capabilities without the delay associated with zero-crossing detection.
Replacement Considerations
Check Vishay's official replacement guide for direct equivalents. Common substitutes may include other Vishay VOT series parts with similar voltage ratings. Ensure any replacement maintains the non-zero crossing characteristic and compatible DIP-5 footprint. Verify that the substitute's IFT and holding current parameters match the design constraints.
