CTB12-1200CWPT

Triacs Overview

The CTB12-1200CWPT is a single Alternistor TRIAC manufactured by Sensata-Crydom, designed for high-voltage switching applications. It features a 1200V repetitive peak off-state voltage and a 12A RMS on-state current capability. The device utilizes a TO-220AB through-hole package with an isolated case connection. It operates within a junction temperature range of -40°C to 125°C. Key electrical characteristics include a maximum holding current of 35 mA and a gate trigger voltage of 1.3 V DC. The component is RoHS compliant and supports snubberless operation.

Triacs Feature Summary

• Snubberless design for simplified circuit implementation
• High voltage blocking capability up to 1200V
• Isolated case connection for safety
• Through-hole mounting for robust mechanical stability

Triacs Applications

• Industrial motor control systems
• Solid-state contactor modules
• High-power AC load switching
• Phase angle control circuits

Triacs Procurement Notes

Verify the specific suffix 'CWPT' against official Sensata-Crydom documentation to confirm pinout and packaging variations. Ensure compatibility with existing thermal management solutions given the TO-220AB form factor. Cross-reference datasheet revisions to confirm compliance status and electrical limits before final integration.

Triacs Selection Notes

Select this component for applications requiring high voltage isolation and snubberless performance. Evaluate thermal dissipation requirements based on the 12A current rating and ambient operating conditions. Confirm that the 1200V rating exceeds the peak line voltage plus transient spikes in the target application environment.

Triacs Part Context

This part belongs to the Crydom Alternistor family, which integrates TRIACs with specific characteristics for improved switching performance. The series is engineered to replace traditional TRIACs in applications demanding higher reliability and reduced external component counts due to snubberless capabilities.

Triacs Replacement Considerations

Direct substitutes may include other 1200V 12A snubberless TRIACs in TO-220AB packages from Sensata-Crydom or compatible manufacturers. Verify electrical parameters such as dV/dt rating and gate sensitivity to ensure functional equivalence.
