VOT8024AM-VT

Overview

The VOT8024AM-VT is a single-channel optoisolator featuring a phototriac output, manufactured by Vishay Semiconductor Opto Division. It provides 3750Vrms isolation voltage and supports an 800V blocking voltage. The device integrates a zero-voltage crossing detector to minimize electromagnetic interference during switching. Key electrical parameters include a maximum RMS on-state current of 100 mA, a typical forward voltage of 1.2V, and a maximum DC forward current of 50 mA. It operates within a temperature range of -55°C to 110°C and is housed in a compact SOP-4 surface-mount package.

Feature Summary

• Integrates a zero-voltage crossing detector for low-noise AC power switching
• Features high static dV/dt immunity of 1000 V/µs to prevent false triggering
• Provides high input sensitivity with a maximum trigger current of 5 mA
• Offers robust insulation with 3750Vrms isolation rating

Applications

• Solid-state relays requiring precise phase control
• Motor control circuits utilizing DSP controllers
• General-purpose AC load switching applications

Procurement Notes

Verify the specific suffix VT indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status and check for recent PCN updates regarding manufacturing site changes or material substitutions. Ensure the selected variant matches the required SOP-4 footprint and lead-free specifications for your assembly process.

Selection Notes

Select this component when zero-crossing detection is mandatory to reduce electrical noise. Compare against non-zero-crossing variants like the VOT8121AM if immediate turn-on is preferred over noise reduction. Ensure the 100 mA output current capacity meets the load requirements and that the SOP-4 package fits the PCB layout constraints.

Part Context

This part belongs to the VOT8024/VOT8121 family of flat SOP-4 optocouplers designed for AC power control. It shares the same physical footprint as the VOT8121AM but differs internally by including a zero-crossing circuit. This family is engineered for high reliability in industrial environments with wide operating temperature ranges.

Replacement Considerations

The VOT8024AM-T2 is a verified alternative from the same manufacturer offering identical electrical characteristics and pinout configuration.
