CTB12-1200SW

Triacs Overview

The CTB12-1200SW is a logic-sensitive gate TRIAC from Sensata-Crydom, designed for through-hole mounting in TO-220AB packages. It features a maximum off-state voltage of 1.2 kV and an RMS on-state current rating of 12 A. The device operates within a junction temperature range of -40°C to 125°C and has a maximum gate trigger voltage of 1.3 V.

Triacs Feature Summary

• Logic-sensitive gate architecture enables direct interface with standard digital logic circuits without requiring high drive currents.
• High voltage blocking capability supports operation in demanding AC power switching applications up to 1.2 kV.

Triacs Applications

• Industrial motor control systems
• Solid-state relay modules
• Power regulation circuits

Triacs Procurement Notes

Verify the specific suffix 'SW' against official datasheets to confirm package and pinout compatibility. Confirm lifecycle status as obsolete before finalizing designs. Ensure thermal management meets the 125°C junction limit during operation.

Triacs Selection Notes

Select this component when high voltage isolation and logic-level gate sensitivity are required. The TO-220AB package facilitates heatsinking for sustained 12 A loads. Consider alternative active parts if long-term supply continuity is critical due to obsolete status.

Triacs Part Context

This TRIAC belongs to the Crydom family of power switching devices, widely used in industrial automation. The CTB series specifically targets applications requiring robust AC control with simplified gate driving requirements, bridging the gap between discrete semiconductors and integrated modules.

Triacs Replacement Considerations

As the part is marked obsolete, verify equivalent logic-sensitive TRIACs with matching 1.2 kV and 12 A ratings. Cross-reference pinouts and thermal characteristics to ensure mechanical and electrical compatibility in existing assemblies.
