CQ92D APM

Triacs Overview

The CQ92D APM is a discontinued epoxy-molded silicon Triac from the Central Semiconductor CQ92 series, housed in a TO-92 case. It features full-wave AC control with gate triggering in all four quadrants. Key electrical ratings include a peak repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 1.0 A at TC=50°C. The device supports a peak one-cycle surge current (ITSM) of 20 A and operates within a junction temperature range of -40 to +125 °C.

Triacs Feature Summary

• Four-quadrant gate triggering capability for full-wave AC control applications
• Epoxy molded construction in a TO-92 through-hole package
• High thermal resistance characteristics suitable for general purpose switching

Triacs Applications

• Full wave AC control circuits
• General purpose mains power AC switching
• Light dimming and motor speed control systems

Triacs Procurement Notes

This component has been officially transitioned to End of Life status by Central Semiconductor Corp. No replacement part number is currently available from the manufacturer. Procurement should focus on verifying existing inventory or identifying alternative sources through distributor networks, as direct manufacturing orders are no longer supported.

Triacs Selection Notes

Designers requiring a 400 V, 1.0 A TRIAC in a TO-92 package must account for the EOL status of this specific part. Selection criteria should prioritize equivalent electrical parameters such as VDRM, IT(RMS), and four-quadrant sensitivity. Verification of lead compatibility and thermal management requirements is essential when substituting with other manufacturers' offerings.

Triacs Part Context

The CQ92D belongs to the broader CQ92 series, which includes variants rated at 200 V (CQ92B), 600 V (CQ92M), and 800 V (CQ92N). All members share identical physical dimensions and basic operational characteristics, differing primarily in their maximum blocking voltage capabilities. This series was designed for cost-effective, low-power AC switching tasks.

Triacs Replacement Considerations

Central Semiconductor lists N/A for the CQ92D APM replacement. Engineers must source equivalents from other vendors. Ensure the substitute matches the TO-92 footprint, 400 V rating, and 1.0 A current capacity while confirming four-quadrant trigger functionality.
