CTB12-1200CPT

Triacs Overview

The CTB12-1200CPT is a TRIAC component manufactured by Sensata-Crydom, designed for general-purpose AC switching applications. It features a peak repetitive off-state voltage (VDRM) of 1200 V and an RMS on-state current (IT(RMS)) of 12 A. The device utilizes a TO-220AB package with flange mounting for effective thermal management. Key electrical characteristics include a maximum DC gate trigger current of 25 mA and a maximum DC gate trigger voltage of 1.3 V. The component supports logic-level triggering and is suitable for phase control, static switching, light dimming, and motor speed control.

Triacs Feature Summary

• High voltage blocking capability with 1200 V rating
• Robust 12 A RMS on-state current handling
• Logic-level compatible gate trigger specifications
• Flange mount construction for efficient heat dissipation

Triacs Applications

• Phase control circuits
• Static switching systems
• Light dimming equipment
• Motor speed control units

Triacs Procurement Notes

Verify the specific suffix 'PT' against official datasheets to confirm pin configuration or packaging variations. Ensure compatibility with existing thermal interface materials for the TO-220AB flange mount. Cross-reference manufacturer documentation for any updates regarding RoHS compliance status or alternative lead-free options.

Triacs Selection Notes

Select this component when high voltage isolation and moderate current capacity are required in a compact form factor. The 1200 V rating provides safety margin for industrial AC lines. Consider the 12 A continuous current limit and ensure adequate heatsinking is implemented to maintain junction temperatures within specified limits during operation.

Triacs Part Context

This part belongs to the CTA/CTB12 series from Crydom, which offers TRIACs in various voltage ratings including 400, 600, 800, and 1200 V. The series is engineered for general-purpose AC switching tasks. The CTB12-1200CPT specifically addresses applications requiring higher voltage withstand capabilities while maintaining standard logic-level gate drive requirements.

Triacs Replacement Considerations

Direct substitutes may include other 1200 V, 12 A TRIACs in TO-220AB packages from manufacturers like STMicroelectronics or Infineon. Verify equivalent IT(RMS), VDRM, and IGT specifications before substitution. Ensure mechanical dimensions and thermal resistance values match the original design constraints.
