Overview
The Central Semiconductor CQDD-16M BK is a surface mount silicon triac in a D2PAK package, rated for 16 A RMS on-state current and 600 V peak repetitive off-state voltage. It features gate triggering across all four quadrants with a typical gate trigger current of 25 mA in Quadrants I, II, and III. The device supports a peak one-cycle surge current of 110 A and operates within a junction temperature range of -40°C to +125°C. Electrical characteristics include a maximum holding current of 25 mA and a critical rate of rise of on-state current (di/dt) of 10 A/μs.
Feature Summary
- Epoxy molded silicon construction designed for full wave AC control applications
- Gate triggering capability provided in all four quadrants
- D2PAK surface mount case configuration for automated manufacturing
Applications
- Full wave AC control systems
- General purpose mains power switching
- Phase angle function controllers
Procurement Notes
This component has been transitioned to End of Life status by the manufacturer. Availability is restricted to existing stock only, as production has ceased. Customers should verify current inventory levels with authorized distributors immediately. Last purchase orders must be placed within six months of the official notice date, with final shipments occurring within twelve months. Minimum order quantities may apply during this liquidation period.
Selection Notes
Select the CQDD-16M BK when a 600 V rating is sufficient for the application; otherwise, consider the CQDD-16N variant for 800 V requirements. Verify that the thermal resistance of 60 °C/W from junction to ambient meets the system's cooling constraints. Ensure the gate drive circuit can supply at least 75 mA to guarantee reliable triggering in Quadrant IV operation under all conditions.
Part Context
The CQDD-16M BK belongs to the CQDD series of 16 Amp silicon triacs manufactured by Central Semiconductor Corp. This series includes variants with different voltage ratings, such as the CQDD-16N, and other current ratings like the CQDD-4M and CQDD-25M. All devices in the DPAK and D2PAK packages have been discontinued and classified as End of Life.
Replacement Considerations
No direct replacement part numbers are available from Central Semiconductor for this model. The manufacturer indicates that no substitutes are currently listed and offers assistance in locating alternate sources via their engineering team. Designers must evaluate third-party equivalents based on matching electrical parameters and package dimensions.
