Overview
The VOT8025AB-V is a Triac output optocoupler featuring an integrated zero-crossing circuit. It provides 5300 Vrms isolation voltage and supports an on-state RMS current of 100 mA with a maximum off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40°C to +110°C and utilizes a 6-SMD surface-mount package. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.2 V, power dissipation of 250 mW, and a trigger current of 5 mA.
Feature Summary
- Integrated zero-crossing detection circuit for reduced electromagnetic interference
- High static dV/dt rating of 1000 V/μs for noise immunity
- High input sensitivity with low trigger current requirements
- Compact SMD-6 packaging for space-constrained designs
Applications
- Control of resistive, inductive, and capacitive loads
- Motor control circuits
- Solenoid driver interfaces
- Solid-state relay implementations
Procurement Notes
Verify the specific suffix variant against the manufacturer datasheet to ensure correct packaging and tape specifications. Confirm that the 5300 Vrms isolation rating meets system safety standards. Validate thermal management requirements for the SMD-6 package under continuous load conditions. Ensure compatibility with digital logic levels given the 5 mA trigger current specification.
Selection Notes
Select this component when zero-crossing switching is required to minimize EMI and inrush currents. The 800 V blocking voltage suits single-phase AC applications. The 100 mA output current limits suitability to low-power loads or pilot stages for larger TRIACs. Verify that the 5300 Vrms isolation exceeds the system's creepage and clearance requirements.
Part Context
This part belongs to Vishay's VOT8025A series of light-controlled silicon output optocouplers. The series expands the company's portfolio with compact DIP-6 and SMD-6 options. These devices are designed for high stability and noise isolation in household appliances and industrial equipment. The VOT8025AB-V specifically denotes the zero-crossing variant within this family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Vishay cross-reference guides for verified alternatives.
