Overview
The VOT8024AB-T1 is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a PhotoTriac output with an integrated zero-crossing circuit, designed for surface-mount applications in a 4-SMD package. The device provides high isolation voltage of 5300 Vrms and supports a maximum off-state voltage (VDRM) of 800 V. Key electrical parameters include a forward current (If) of 50 mA, forward voltage (Vf) of 1.2 V, and power dissipation (Pd) of 250 mW. It operates within a temperature range of -55°C to +110°C and has a maximum gate trigger current of 5 mA.
Feature Summary
- Integrated zero-crossing detection circuitry for reduced electromagnetic interference during switching
- High insulation voltage capability ensuring safe galvanic isolation between input and output circuits
- Surface-mount SMD-4 packaging optimized for automated assembly processes
Applications
- Solid-state relay driver circuits
- AC motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix 'T1' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the selected variant matches the required zero-crossing timing specifications for the target application environment.
Selection Notes
Select this component for designs requiring precise phase-angle control with minimal noise generation. The built-in zero-crossing feature simplifies design complexity compared to non-zero-crossing alternatives. Verify that the 800 V blocking voltage meets the peak line voltage requirements of the AC load being controlled.
Part Context
This part belongs to the VOT8024 series of Triac output optocouplers from Vishay. It shares core electrical characteristics with variants like VOT8024AB but differs in packaging format. The T1 suffix specifically denotes reel packaging, distinguishing it from tube-packaged equivalents such as the VOT8024AB.
Replacement Considerations
Direct substitutes include other Vishay VOT8024 series variants with compatible pinouts. Cross-brand replacements require verification of isolation voltage, trigger current, and zero-crossing functionality to ensure circuit compatibility.
