CTB08-1200BWPT

Triacs Overview

The Sensata-Crydom CTB08-1200BWPT is a Triac Alternistor, specifically designed as a snubberless device. It features a through-hole TO-220AB package and supports a maximum off-state voltage of 1.2 kV with an on-state RMS current rating of 8 A. The component is classified as obsolete and is no longer manufactured by the supplier.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC networks
• Sensitive gate configuration for reliable triggering at low signal levels
• Through-hole mounting in a TO-220AB package

Triacs Applications

• AC power switching applications requiring reliable gate triggering
• Control circuits for heavy-duty electrical equipment
• Industrial motor control systems

Triacs Procurement Notes

This component is officially marked as obsolete and is no longer manufactured. Procurement requires verification of substitute part numbers, such as the TXDV1212RG, to ensure compatibility with existing designs. Availability is limited to remaining stock or alternative sources.

Triacs Selection Notes

Selection should focus on the snubberless capability which simplifies circuit design by removing external components. The sensitive gate feature ensures operation with low-power control signals. Verify that the 1.2 kV blocking voltage and 8 A current rating meet the specific load requirements of the application.

Triacs Part Context

The CTB08-1200BWPT belongs to the Alternistor family of Triacs from Sensata-Crydom. These devices are engineered for high-reliability AC power control without the complexity of traditional snubber circuits. The product line targets industrial applications demanding robust performance in harsh electrical environments.

Triacs Replacement Considerations

The TXDV1212RG is listed as a similar available substitute. Verify pinout compatibility and thermal characteristics when transitioning to this replacement part to maintain system integrity.
