CS3P-40N

Triacs Overview

The CS3P-40N is a Silicon Controlled Rectifier (SCR) manufactured by Central Semiconductor Corp. It features an isolated tab configuration with a maximum average on-state current of 40 A and a repetitive peak off-state voltage range spanning from 200 V to 1200 V. The device utilizes a TO-220AB package for flange mounting, providing electrical isolation between the terminal and the heatsink. It is designed for high-power switching applications requiring robust thermal management and reliable gate triggering characteristics within standard industrial temperature ranges.

Triacs Feature Summary

• Isolated tab construction ensures electrical separation between the main power terminal and the mounting hardware
• High current handling capability supports demanding power control loads
• Wide voltage rating availability accommodates diverse circuit requirements

Triacs Applications

• Industrial motor speed control systems
• AC power regulation circuits
• Solid-state relay implementations

Triacs Procurement Notes

Verify the specific voltage suffix corresponding to the required blocking voltage level, as the base model covers a range. Confirm RoHS compliance status and lead-free plating options prior to ordering. Ensure the selected variant matches the exact thermal and electrical specifications needed for the target application design.

Triacs Selection Notes

Select the appropriate voltage code based on the maximum reverse voltage present in the circuit. Consider the thermal resistance of the mounting interface when designing the heatsink system. Verify that the gate trigger current requirements align with the driving circuit capabilities to ensure reliable turn-on under all operating conditions.

Triacs Part Context

This component belongs to Central Semiconductor's family of high-power SCRs designed for industrial power control. The CS3P series specifically offers isolated tab packages to simplify mounting and improve safety in high-voltage environments. These devices are commonly used where robust, reliable switching of high currents is required.

Triacs Replacement Considerations

Direct replacements include other 40A isolated tab SCRs from manufacturers such as Littelfuse or Vishay. Ensure the replacement part maintains the same pinout, isolation voltage rating, and thermal characteristics. Verify that the gate trigger parameters are compatible with the existing drive circuitry.
