MOC3022S-TA1

Triac, SCR Output Optoisolators Overview

The MOC3022S-TA1 is a Triac and SCR output optocoupler manufactured by Lite-On Inc. It features a 6-pin SMD-6 Gull Wing package designed for surface mount applications. The device provides one channel of isolation with an insulation voltage of 5000 Vrms. Key electrical parameters include a maximum forward current (If) of 50 mA, a forward voltage (Vf) of 1.15 V, and power dissipation (Pd) of 330 mW. The phototriac output supports a peak off-state voltage (VDRM) of 400 V. It operates without a zero-crossing circuit and functions within a temperature range of -40°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage isolation between input and output circuits
• Designed for direct driving of triac and SCR loads
• Utilizes a compact surface-mount package for automated assembly

Triac, SCR Output Optoisolators Applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix TA1 to confirm the tape and reel packaging format and pin configuration. Ensure the component matches the required 6-pin SMD footprint for PCB layout compatibility. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent thermal overstress during operation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero crossing switching is acceptable for the load type. Compare the 400 VDRM rating against the peak line voltage to ensure adequate margin. Consider the 5000 Vrms isolation level for safety compliance requirements in mains-connected designs.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC30 series of triac driver optocouplers from Lite-On. It serves as a solid-state interface for controlling AC power devices. The series includes variants with and without zero-crossing detection, offering flexibility for different noise immunity and switching speed requirements in industrial and consumer electronics.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible alternatives include the MOC3021S-TA1 and MOC3023S-TA1 from Lite-On, which share similar pinouts but differ in internal circuitry or voltage ratings. Verify that substitute parts maintain the same 6-pin SMD package and isolation voltage specifications.
