CTB24-1200BW

Triacs Overview

The CTB24-1200BW is a single TRIAC alternistor from the Sensata-Crydom product line, housed in a TO-220AB package. It features a maximum repetitive peak off-state voltage of 1.2 kV and an RMS on-state current rating of 24 A. The device has a holding current specification of 75 mA. This component is designed for high-voltage AC power control applications requiring robust switching capabilities within a standard through-hole mounting configuration.

Triacs Feature Summary

• Single element TRIAC configuration for AC power switching
• High voltage blocking capability up to 1.2 kV
• Standard TO-220AB through-hole package for panel or board mounting

Triacs Applications

• Industrial motor control systems
• High-voltage AC heating regulation
• Solid state relay output stages

Triacs Procurement Notes

Verify the specific datasheet revision and manufacturer lot codes upon order confirmation. Confirm that the TO-220AB package dimensions match the target PCB or panel cutouts. Check for any recent product change notifications regarding material composition or lead plating specifications to ensure compliance with project requirements.

Triacs Selection Notes

Select this component when a single-phase TRIAC with 1.2 kV blocking voltage and 24 A continuous current capacity is required. Ensure the thermal management design accounts for the TO-220AB package's heat dissipation limits. Verify that the gate trigger characteristics align with the driving circuit's output voltage and current capabilities.

Triacs Part Context

This part belongs to the Crydom family of thyristors, which are widely used in industrial automation and power electronics. The CTB series typically offers reliable performance in harsh environments. As a discrete semiconductor device, it serves as a fundamental building block for constructing custom power controllers and solid-state switching modules.

Triacs Replacement Considerations

Consult official Sensata-Crydom documentation for direct cross-references. Generic replacements must match the 1.2 kV voltage rating, 24 A current rating, and TO-220AB package form factor. Verify gate trigger parameters before substituting.
