MOC3023TM

Triac, SCR Output Optoisolators Overview

The MOC3023TM is a single-channel Triac output optocoupler manufactured by onsemi. It features a PhotoTriac output without zero-crossing circuitry, suitable for random phase control applications. The device provides high isolation with an insulation voltage of 5300 Vrms and supports a peak repetitive off-state voltage (VDRM) of 400 V. It operates within a temperature range of -40°C to +85°C and is housed in a 6-pin PDIP package. Key electrical parameters include a maximum forward current of 60 mA, a forward voltage of 1.15 V, and a maximum trigger current of 5 mA.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an infrared emitting diode with a light-sensitive Triac for galvanic isolation
• Provides robust electrical isolation between input and output circuits
• Designed for random phase firing applications requiring non-zero-crossing switching

Triac, SCR Output Optoisolators Applications

• Solid state relay driver circuits
• AC power control systems
• Motor speed control interfaces

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check for end-of-life status or obsolescence notices from onsemi before finalizing design-in decisions. Ensure compliance with RoHS directives if applicable to the target market regulations.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing switching. Consider the 400 V VDRM rating against the maximum line voltage peaks in the application. Evaluate the 5300 Vrms isolation requirement for safety standards. Compare thermal dissipation capabilities at 330 mW against ambient operating conditions.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC series of Triac output optocouplers from onsemi. It serves as a discrete interface solution for controlling AC loads. The PDIP-6 package facilitates through-hole mounting. It is distinct from zero-crossing variants like the MOC3021 series.
