MOC3009

Triac, SCR Output Optoisolators Overview

The MOC3009 is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates a Gallium Arsenide infrared emitting diode with a light-activated silicon triac output. The device provides an isolation voltage of 5300Vrms and operates within a temperature range of -40°C to 100°C. Packaged in a standard 6-DIP (0.400 inch, 10.16mm) through-hole configuration, it supports non-zero crossing switching for AC load control applications.

• General-purpose AC load switching

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific manufacturer designation when sourcing, as this component may be produced under various corporate entities including Isocom Components or Texas Instruments. Confirm that the received unit matches the required 6-DIP package dimensions and pinout configuration. Ensure the supplier documentation explicitly states the 5300Vrms isolation rating and non-zero crossing functionality to guarantee compatibility with the target circuit design.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring robust isolation between low-power control logic and high-voltage AC loads. The non-zero crossing feature makes it suitable for resistive loads where immediate turn-on is acceptable. Consider the 6-DIP package for through-hole assembly processes. Evaluate thermal management requirements given the operating temperature limits up to 100°C.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC3009/301x series of optocouplers from Isocom Components. These components are widely used in industrial automation and consumer electronics for interfacing microcontrollers with mains-powered devices. The series offers a cost-effective solution for galvanic isolation in power control circuits.

Triac, SCR Output Optoisolators Replacement Considerations

Cross-reference with other manufacturers' non-zero crossing triac output optocouplers offering similar 5300Vrms isolation and 6-DIP packaging. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
