Overview
The Central Semiconductor CQDD-25M BK is a surface mount silicon triac in a D2PAK package, rated for 25 A RMS on-state current. It offers peak repetitive off-state voltages of 600 V and supports full-wave AC control with gate triggering in all four quadrants. Key electrical parameters include a peak one-cycle surge current of 150 A, an I²t value of 94 A²s, and a maximum junction temperature of +125 °C. Thermal resistance is specified at 1.7 °C/W (junction-to-case) and 60 °C/W (junction-to-ambient). The device features a critical rate of rise of on-state current of 10 A/μs.
Feature Summary
- Four-quadrant gate triggering capability for reliable AC switching
- Epoxy molded construction for surface mount applications
- High thermal efficiency with low junction-to-case thermal resistance
Applications
- Full-wave AC control circuits
- Light dimmer systems
- Motor speed controls
Procurement Notes
This component has been officially transitioned to End of Life status by the manufacturer. Current availability is restricted to existing stock only, as production has ceased. Buyers should verify remaining inventory levels directly with authorized distributors or the manufacturer's support team before initiating orders.
Selection Notes
Select this part for high-current surface mount designs requiring robust AC switching. Ensure the circuit design accommodates the 600 V blocking voltage and 25 A continuous current rating. Verify that the PCB layout supports the D2PAK footprint and provides adequate thermal dissipation to maintain junction temperatures within the specified operating range.
Part Context
The CQDD-25M BK belongs to the Central Semiconductor CQDD series of surface mount silicon triacs. This family includes variants with different voltage ratings, such as the CQDD-25N which offers an 800 V rating. All devices in the DPAK and D2PAK packages from this manufacturer have been discontinued.
Replacement Considerations
No direct replacement part numbers are listed in the official documentation. The manufacturer indicates that no substitutes are available and advises contacting [email protected] for assistance in locating alternate sources.
