VOT8024AM-T

Overview

The VOT8024AM-T is a single-channel phototriac output optocoupler in a flat SOP-4 surface-mount package. It features an integrated zero-crossing detector circuit for precise AC load control. Key electrical parameters include a peak repetitive off-state voltage (VDRM) of 800 V, an on-state RMS current (IT(RMS)) of 100 mA, and an isolation voltage of 3750 Vrms. The device operates with a maximum trigger current of 5 mA and supports a wide temperature range from -55°C to +115°C.

Feature Summary

• Integrated zero-voltage crossing detection for reduced electromagnetic interference
• High static dV/dt rating of 1000 V/μs for noise immunity
• Compact flat 2.0 mm SOP-4 surface-mount footprint

Applications

• Solid-state relays
• Motor control circuits
• Lighting dimmers

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm packaging configuration. The 'T' suffix typically denotes tape and reel packaging, which differs from cut tape or tube options. Confirm insulation system certifications such as UL, cUL, and VDE requirements match the target application safety standards before procurement.

Selection Notes

Select this component when high dv/dt immunity and zero-crossing switching are required in a compact SMD form factor. Ensure the load current does not exceed the 100 mA IT(RMS) limit. Verify that the 800 V blocking voltage is sufficient for the AC line voltage being controlled. Check thermal dissipation capabilities within the SOP-4 package constraints.

Part Context

This part belongs to Vishay's VOT8024A series of triac output optocouplers designed for AC power switching applications. The series provides galvanic isolation between low-voltage control logic and high-voltage AC loads. The SOP-4 variant offers a space-saving alternative to traditional DIP packages while maintaining high isolation performance.
