MOC3009XSM

Triac, SCR Output Optoisolators Overview

The MOC3009XSM is a random phase triac output optoisolator manufactured by Isocom Components. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon triac detector, providing electrical isolation for control circuits. The device features a 6-pin DIP package and supports through-hole mounting. Key electrical parameters include a maximum forward voltage of 1.5V, an isolation voltage of 5300Vrms, and a typical rise/fall time of 2μs. It operates within a temperature range of -55°C to 100°C and complies with UL (E91231), VDE 0884, and CECC 00802 standards.

Triac, SCR Output Optoisolators Feature Summary

• AC power switching controls
• Industrial motor control systems
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'XSM' against official Isocom documentation to confirm surface mount or tape-and-reel configuration details. Ensure that the 6-pin DIP form factor matches the target PCB footprint requirements. Cross-reference certification numbers such as UL E91231 and VDE 0884 with current regulatory databases to confirm active status. Confirm thermal management capabilities align with the specified operating temperature range of -55°C to 100°C for the intended environment.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triac triggering is required rather than zero-crossing detection, allowing for phase-angle control applications. The 5300Vrms isolation rating makes it suitable for high-voltage industrial environments where robust galvanic isolation is critical. Consider the 2μs response time for timing-sensitive AC switching tasks. Verify compatibility with the driving logic levels given the 1.5V maximum forward voltage specification.
