Overview
The VOT8025AB-VT2 is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a GaAs infrared LED optically coupled to a photosensitive zero-crossing TRIAC in an SMD-6 package. Key electrical parameters include a maximum continuous on-state current of 100 mA, a peak off-state blocking voltage (VDRM) of 800 V, and an isolation voltage of 5300 Vrms. The device operates with a typical forward voltage of 1.2 V and a maximum trigger current of 5 mA. It supports a wide operating temperature range from -40°C to +110°C.
Feature Summary
- Integrated zero-crossing circuit for low electromagnetic interference switching
- High static dV/dt capability of 1000 V/µs for noise immunity
- Robust surge withstand capability suitable for demanding environments
Applications
- Solid state relays
- Motor control circuits
- Lighting dimmers
Procurement Notes
Verify the specific suffix VT2 corresponds to the reel packaging configuration required for your assembly line. Confirm that the SMD-6 footprint matches your PCB design guidelines. Ensure compliance with RoHS3 standards if environmental regulations apply to your manufacturing process. Cross-reference the datasheet revision date to confirm technical specifications have not changed.
Selection Notes
Select this component when high isolation voltage and zero-crossing functionality are required for AC load control. The 100 mA output rating suits low-power applications such as small motors or lighting loads. Consider the SMD-6 package size constraints during layout planning. Verify that the 800 V blocking voltage meets the peak line voltage requirements of the target application.
Part Context
This part belongs to the VOT8025A family of Triac output optocouplers. It shares functional similarities with models like VOT8024AM but differs in packaging and isolation ratings. The VOT8025 series is designed for general-purpose AC switching applications requiring galvanic isolation between control and load sides.
Replacement Considerations
Direct substitutes may include other Vishay VOT8025 variants with compatible pinouts. Verify package dimensions and electrical characteristics before substitution. Generic replacements must match the 100 mA current rating and 5300 Vrms isolation level.
