CTA24-1200BW

Triacs Overview

The CTA24-1200BW is a Triac Alternistor device manufactured by Sensata-Crydom, housed in a TO-220AB package. It features a single configuration with an off-state voltage of 1.2 kV and a maximum on-state RMS current of 24 A. The component operates within a junction temperature range of -40°C to 125°C. Key electrical limits include a maximum hold current of 50 mA and a maximum gate trigger current of 50 mA. This part is classified as obsolete.

Triacs Feature Summary

• Snubberless Alternistor design for simplified circuit integration
• High voltage blocking capability suitable for industrial applications
• Robust thermal performance across extended temperature ranges

Triacs Applications

• Industrial motor control systems
• AC power switching circuits
• Solid state relay modules

Triacs Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement requires verification of remaining stock availability through authorized distributors or surplus suppliers. Buyers should confirm the authenticity of the TO-220AB package and check for any specific handling requirements due to the end-of-life status. Cross-referencing with current replacement series is recommended before finalizing orders.

Triacs Selection Notes

Engineers selecting this part must account for its obsolete status and potential supply chain constraints. The 1.2 kV rating and 24 A current capacity define its operational envelope. Designers should verify that the snubberless feature meets their specific load characteristics without additional external components. Thermal management remains critical given the TO-220AB package limitations under high current loads.

Triacs Part Context

The CTA24-1200BW belongs to the Triac family within Sensata-Crydom's portfolio. It serves as a solid-state switching element designed for AC power control. The Alternistor technology distinguishes it from standard Triacs by eliminating the need for external snubber networks. This simplifies board layout and improves reliability in high-voltage industrial environments.

Triacs Replacement Considerations

As an obsolete part, direct substitutes are not explicitly confirmed in public documentation. Engineers should consult Sensata-Crydom for current series replacements that match the 1.2 kV and 24 A specifications. Verify pin compatibility and thermal resistance when transitioning to newer packages.
