Overview
The CS3P-40P is a Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp. It features a single element configuration housed in an isolated TO-3P flange mount package with three terminals. The device supports a maximum RMS on-state current of 30 A and a non-repetitive peak on-state current of 400 A. It is rated for a maximum repetitive peak off-state voltage of 800 V. Key gate parameters include a maximum DC gate trigger current of 50 mA and a maximum DC gate trigger voltage of 1.5 V. The component has a metal encapsulation body designed for high-power applications requiring electrical isolation.
Feature Summary
- Isolated tab construction for direct mounting to heatsinks without additional insulators
- High surge current capability suitable for inductive load switching
- Robust metal flange package ensuring efficient thermal dissipation
Applications
- Industrial motor control circuits
- High-power AC power regulation systems
- Welding equipment power stages
Procurement Notes
Verify the specific voltage rating suffix, as the CS3P series typically spans multiple voltage grades (e.g., 200V to 1200V). Confirm RoHS compliance status, as older Central Semiconductor stock may be non-compliant. Ensure the TO-3P pinout matches the target circuit design before integration.
Selection Notes
Select this component when an isolated SCR with 30A continuous current handling is required. Verify that the 800V blocking voltage meets the circuit's peak reverse voltage requirements. Consider the TO-3P package size constraints for the mechanical assembly.
Part Context
This part belongs to the Central Semiconductor CS3P family of isolated tab SCRs. These devices are engineered for high-current industrial applications where electrical isolation between the terminal and the mounting surface is mandatory. The series offers various voltage ratings to accommodate different line voltages.
Replacement Considerations
Direct replacements within the same manufacturer's lineup include CS3P-40B or CS3P-40M, provided the voltage rating matches the application requirements. Cross-manufacturer equivalents must match the 30A RMS current, 800V voltage, and TO-3P isolated package specifications.
