CQ220-10D

Triacs Overview

The CQ220-10D is a four-quadrant logic level TRIAC manufactured by Central Semiconductor Corp. It is housed in a TO-220AB package and features an isolated tab for mounting. The device supports a repetitive peak off-state voltage of 800V and an RMS on-state current rating of 10A. It is designed for AC power control applications requiring high reliability and thermal stability.

Triacs Feature Summary

• Four-quadrant gate triggering capability for reliable switching across all input polarities
• Isolated tab construction allows direct heatsink mounting without additional insulators
• Logic-level sensitivity enables direct drive from standard digital logic circuits

Triacs Applications

• Solid state relay output stages
• AC motor speed control circuits
• Lighting dimmer modules

Triacs Procurement Notes

This component has been officially classified as End of Life (EOL) by the manufacturer. No replacement part number is currently available within the same product family. Procurement should focus on identifying equivalent specifications from other manufacturers or redesigning the circuit to accommodate alternative components.

Triacs Selection Notes

Designers must verify that the required 800V blocking voltage and 10A current capacity meet the application's peak load requirements. Consider the thermal resistance of the TO-220AB package when designing the heatsink, as the isolated tab simplifies mounting but requires proper thermal interface material selection.

Triacs Part Context

The CQ220 series represents a line of general-purpose TRIACs previously offered by Central Semiconductor. This specific model belongs to the 10A current rating tier within the TO-220 form factor. The series has been discontinued, marking the end of production for this class of devices.

Triacs Replacement Considerations

No direct replacement part number is listed by the manufacturer. Engineers should search for generic 10A, 800V TRIACs in TO-220 packages from other suppliers, ensuring pinout compatibility and thermal characteristics match the original design constraints.
