Overview
The CSDD-12N BK is a surface mount Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp. It features an 800 V peak repetitive off-state voltage and a 12 A RMS on-state current rating at 90°C case temperature. The device utilizes a D2PAK package with lead codes for cathode, anode, gate, and anode connections. Key electrical characteristics include a maximum gate trigger current of 15 mA and a holding current of 20 mA. Thermal resistance values are specified as 60 °C/W junction-to-ambient and 2.5 °C/W junction-to-case.
Feature Summary
- Designed for sensing circuit applications and control systems
- Epoxy molded construction for surface mount integration
- High surge capability with 110 A peak one-cycle surge rating
Applications
- Sensing circuits
- Control systems
Procurement Notes
This component has been transitioned to End of Life status by the manufacturer. Current availability is restricted to existing stock only, with no further production planned. Buyers should verify stock levels carefully before ordering, as replacements are not available from this manufacturer. Last purchase orders may be subject to specific cutoff dates defined in official discontinuation notices.
Selection Notes
Select the CSDD-12N BK when an 800 V SCR with 12 A continuous current handling is required in a surface mount configuration. Ensure the application design accounts for the 100 A/μs critical rate of rise of on-state current. Verify thermal management capabilities against the 60 °C/W junction-to-ambient resistance specification for reliable operation within the -40 to +125 °C junction temperature range.
Part Context
The CSDD-12N belongs to the CSDD series of surface mount silicon controlled rectifiers produced by Central Semiconductor Corp. This series includes variants with different voltage ratings, such as the 600 V CSDD-12M. All thyristors manufactured in the DPAK and D2PAK packages by this manufacturer have been discontinued and classified as End of Life.
Replacement Considerations
No replacement part numbers are available from Central Semiconductor Corp for this component. The manufacturer indicates that no alternate source products are currently listed for this specific part number.
