CTB12-1200SWPT

Triacs Overview

The CTB12-1200SWPT is a logic-sensitive gate TRIAC manufactured by Sensata-Crydom, designed for through-hole mounting in the TO-220AB package. It features a maximum repetitive peak off-state voltage of 1200 V and a continuous on-state current rating of 12 A. The device utilizes a sensitive gate architecture with a maximum gate trigger voltage of 1.3 V, enabling direct interface with standard logic circuits. Key electrical characteristics include a non-repetitive peak surge current capacity of 100 A and an on-state RMS current handling capability suitable for high-power switching applications.

Triacs Feature Summary

• Logic-sensitive gate structure allows direct control from low-power digital logic sources without additional driver circuitry
• High voltage blocking capability supports operation in demanding power electronics environments
• Robust thermal management design inherent to the TO-220AB package facilitates heat dissipation

Triacs Applications

• Solid-state relay (SSR) output stages
• Motor control drive circuits
• Industrial power switching modules

Triacs Procurement Notes

Verify the specific suffix 'SWPT' against official Sensata-Crydom documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure the procurement specification matches the required logic-sensitive gate variant rather than standard gate types. Cross-reference the datasheet revision date to validate parameter consistency before integration into final designs.

Triacs Selection Notes

Select this component when a high-voltage, high-current TRIAC requires direct logic-level triggering without external gate drivers. The TO-220AB package is appropriate for applications requiring efficient thermal transfer to a heatsink. Consider the 12 A continuous current rating and 1200 V blocking voltage as primary constraints for load matching and system safety margins.

Triacs Part Context

This part belongs to the Sensata-Crydom discrete semiconductor portfolio, specifically within the TRIAC category. It complements other power switching devices like the CNR series solid-state relays and DC200D40 MOSFET-based SSRs, offering a fundamental building block for AC power control systems where robust, logic-driven switching is required.

Triacs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Evaluate alternatives based on matching 1200 V/12 A ratings, TO-220AB package compatibility, and logic-sensitive gate specifications.
