Overview
The VOT8025AB-T2 is a high-voltage triac output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a single channel with an integrated zero-crossing detection circuit, ensuring low electromagnetic interference during switching. The device utilizes a surface-mount SMD-6 package and provides robust electrical isolation with an insulation voltage of 5300 Vrms. Key electrical parameters include a maximum continuous on-state RMS current of 100 mA, a blocking voltage (VDRM) of 800 V, and a typical forward voltage of 1.2 V at a forward current of 20 mA. It operates within a temperature range of -40°C to +110°C.
Feature Summary
- Integrated zero-crossing detection circuit for reduced electromagnetic interference
- High isolation voltage capability of 5300 Vrms for safe operation in high-voltage environments
- Surface-mount SMD-6 packaging for compact board integration
Applications
- Solid-state relay driver circuits
- AC power switching applications
- Industrial control systems requiring galvanic isolation
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm package type and tape/reel specifications. Ensure that the selected variant matches the required thermal and electrical ratings for the target application environment. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and compliance with RoHS standards before finalizing procurement orders.
Selection Notes
Select this component when high-voltage isolation and precise AC phase control are required. The integrated zero-crossing feature makes it suitable for applications demanding minimal noise generation. Consider the 100 mA RMS current limit and 800 V blocking voltage when designing the load interface. Ensure the PCB layout supports the SMD-6 footprint and adequate creepage distances for the specified isolation voltage.
Part Context
This device belongs to Vishay's family of high-voltage optocouplers designed for industrial and consumer AC switching applications. It complements other variants such as the VOT8025AB-VT and VOT8025AB-V, which offer similar electrical characteristics but differ in package configuration. The T2 suffix typically denotes a specific surface-mount tape and reel packaging option optimized for automated assembly processes.
Replacement Considerations
Direct substitutes include VOT8025AB-VT and VOT8025AB-V from the same manufacturer series. Verify pin compatibility and package dimensions when transitioning between surface-mount and through-hole variants. Ensure that alternative components meet or exceed the 5300 Vrms isolation and 800 V blocking voltage requirements.
