CQ92DT

Triacs Overview

The CQ92DT is a silicon TRIAC from the Central Semiconductor CQ92 series, housed in a TO-92 case. It features a peak repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 1.0 A at 50°C. The device supports gate triggering in all four quadrants with a maximum gate trigger voltage (VGT) of 2.0 V and a holding current (IH) of 3.0 mA. It has a junction temperature range of -40 to +125°C and a storage temperature range of -40 to +150°C.

Triacs Feature Summary

• Four-quadrant gate triggering capability for full wave AC control applications
• Epoxy molded construction within a TO-92 case
• High surge current handling with a peak one cycle surge rating of 20 A

Triacs Applications

• Full wave AC control circuits
• Lighting dimmer applications
• Motor speed control systems

Triacs Procurement Notes

This component is classified as End of Life (EOL). No replacement part number is available from the manufacturer. Last purchase orders must be placed within six months of the notice date, with final shipments occurring twelve months after the notice. Contact engineering support for technical data or alternate source assistance.

Triacs Selection Notes

Select this device for low-power AC switching requiring 400 V blocking capability and 1.0 A continuous current. Verify that the application operates within the specified thermal limits, noting the 180 °C/W thermal resistance from junction to ambient. Ensure the gate drive circuit can supply the required 3.0 mA trigger current across all operating quadrants.

Triacs Part Context

The CQ92DT belongs to the CQ92 series, which includes variants rated at 200 V (CQ92BT), 600 V (CQ92MT), and 800 V (CQ92NT). All members share identical electrical characteristics except for the peak repetitive off-state voltage. The series utilizes a standard TO-92 package with MT1, Gate, and MT2 lead configuration.

Triacs Replacement Considerations

No direct replacement part number is provided by Central Semiconductor Corp. for the CQ92DT. Users are advised to contact the manufacturer's engineering team for potential alternate sources or design modifications.
