Overview
The VOT8024AB-T2 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.
Feature Summary
- Integrated zero-crossing detection circuitry for reduced electromagnetic interference during AC switching
- High insulation voltage capability ensuring safe galvanic isolation between input and output circuits
- Surface-mount SMD-4 packaging optimized for automated assembly and compact board layouts
Applications
- Solid-state relays requiring precise AC load control
- Motor control interfaces for single-phase AC motors
- General-purpose AC power switching modules
Procurement Notes
Verify the specific suffix T2 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 4-SMD footprint dimensions. Validate thermal management requirements against the specified 250 mW power dissipation limit under worst-case operating conditions.
Selection Notes
Select this component when zero-crossing functionality is required to minimize inrush currents and noise. Compare against non-zero-crossing variants like VOT8121 if phase-angle control is needed instead. Consider the 800 V blocking voltage rating relative to peak line voltages. Evaluate the 5300 Vrms isolation rating against safety standards applicable to the target equipment class.
Part Context
This part belongs to Vishay's VOT series of Triac output optocouplers. It is distinct from the VOH series which utilizes phototransistor outputs for digital signaling. The VOT series is specifically engineered for direct interface with AC mains loads, offering built-in protection features not found in standard logic isolators.
Replacement Considerations
Direct substitutes may include other Vishay VOT8024 variants with different packaging or suffixes. Cross-reference pinouts and electrical characteristics carefully when considering alternatives from other manufacturers to ensure functional equivalence.
