VOT8024AM-VT2

Overview

The VOT8024AM-VT2 is a Triac and SCR output optocoupler manufactured by Vishay Semiconductor Opto Division. It features a flat SOP-4 package with integrated zero-crossing circuitry for precise phase control applications. Key electrical parameters include an isolation voltage of 3750 Vrms, a repetitive peak off-state voltage (VDRM) of 800 V, and a maximum on-state RMS current (It RMS) of 100 mA. The device operates with a typical forward voltage (Vf) of 1.2 V at a maximum DC forward current (If) of 20 mA. It supports a wide operating temperature range from -55°C to +115°C and offers high static dV/dt immunity of 1000 V/μs.

Feature Summary

• Integrated zero-voltage crossing detector for noise-free switching
• High static dV/dt immunity of 1000 V/μs
• Flat 2.0 mm SOP-4 surface mount package

Applications

• Solid state relays
• Motor controls
• Lighting controls

Procurement Notes

Verify the specific suffix VT2 against the manufacturer's datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the required insulation class and agency approvals such as UL, cUL, or VDE. Cross-reference the component marking with official documentation to prevent counterfeit substitution.

Selection Notes

Select this component when high dv/dt immunity and low input sensitivity are required in a compact surface-mount form factor. The integrated zero-crossing feature makes it suitable for AC load control where electromagnetic interference must be minimized. Compare the 100 mA current rating against load requirements to ensure adequate margin.

Part Context

This device belongs to Vishay's family of phototriac output optocouplers designed for AC power switching. Unlike non-zero-crossing variants, this model includes internal logic to trigger conduction near the AC voltage zero point. It serves as an interface between low-voltage digital circuits and high-voltage AC loads.

Replacement Considerations

Check for direct pin-compatible substitutes within the same Vishay series that share the SOP-4 package and 800 V rating. Verify that alternative parts maintain the same zero-crossing functionality and isolation voltage specifications.
