MOC3009XG

Triac, SCR Output Optoisolators Overview

The MOC3009XG is a single-channel optoisolator featuring a random-phase triac output, manufactured by Isocom Components. It provides electrical isolation with a rated voltage of 5300Vrms and is housed in a standard 6-pin DIP package. The device integrates an infrared emitting diode input with a zero-crossing detection-free triac output stage, designed for direct interface with mains-powered loads. Key specifications include a maximum forward voltage of 1.4V for the input LED and a peak repetitive off-state voltage capability for the triac. The component operates within a temperature range of -40°C to 100°C and complies with UL and VDE safety standards.

Triac, SCR Output Optoisolators Feature Summary

• Random-phase triac output configuration for versatile AC load control
• High isolation voltage rating of 5300Vrms for safe mains interfacing
• Integrated infrared LED input for efficient signal transmission
• Compliance with international safety certifications including UL and VDE

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'XG' against the manufacturer's current datasheet to confirm packaging and tape-and-reel specifications. Ensure that the procurement source provides valid UL and VDE certification documentation for compliance requirements. Cross-reference the part number with official distributor catalogs to confirm availability and lead times prior to ordering.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triggering is acceptable for the application, as it lacks zero-crossing protection. Compare the 5300Vrms isolation rating against system voltage requirements. Consider the 6-pin DIP package constraints for PCB layout. Evaluate the thermal management needs given the operating temperature range up to 100°C.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC304 series of optoisolators from Isocom Components. It shares the same physical footprint and basic isolation characteristics with other members of the family but differs in internal trigger circuitry. The series is widely used in industrial control panels where galvanic isolation between low-voltage logic and high-voltage AC lines is required.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers such as ON Semiconductor or Vishay by comparing pinouts, isolation voltages, and trigger currents.
