CQ92MT

Triacs Overview

The CQ92MT is a silicon Triac from the Central Semiconductor CQ92 series, housed in a TO-92 package. It features a peak repetitive off-state voltage of 600 V and an RMS on-state current rating of 1.0 A at 50°C case temperature. The device supports gate triggering in all four quadrants with a typical gate trigger voltage of 2.0 V and current of 3.0 mA. Key electrical characteristics include a holding current of 3.0 mA, a peak one-cycle surge current of 20 A, and a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Four-quadrant gate triggering capability for full-wave AC control applications
• Epoxy molded construction designed for robust performance in switching circuits
• High peak repetitive off-state voltage rating suitable for various line voltages

Triacs Applications

• Full wave AC control applications
• Solid state switching circuits
• Lighting dimmer controls

Triacs Procurement Notes

This component has been officially transitioned to End of Life status by the manufacturer. Last purchase orders must be placed within six months of the discontinuation notice, with final shipments occurring twelve months after that date. Verify availability through authorized distributors or secondary markets as standard supply channels no longer stock this part.

Triacs Selection Notes

Select the CQ92MT when a 600 V blocking voltage and 1.0 A continuous current are required in a TO-92 form factor. Ensure the design accounts for the 180 °C/W thermal resistance for adequate heat dissipation. Confirm that the application requires four-quadrant sensitivity, as other variants in the series may have different voltage ratings but identical current capabilities.

Triacs Part Context

The CQ92MT belongs to the CQ92 series, which includes variants with 200 V (CQ92BT), 400 V (CQ92DT), and 800 V (CQ92NT) ratings. All members share the same 1.0 A RMS current rating, TO-92 package, and four-quadrant triggering specifications. The series was designed for general-purpose AC power control before being discontinued.

Triacs Replacement Considerations

No direct replacement part number is provided by Central Semiconductor Corp. for the CQ92MT. Engineers should consult alternative manufacturers offering equivalent 600 V, 1 A TO-92 Triacs with four-quadrant sensitivity.
