CTB08-1200CW

Triacs Overview

The CTB08-1200CW is a Triac Alternistor from Sensata-Crydom, rated for 1.2 kV reverse voltage and 8 A forward current. It utilizes a snubberless design to eliminate the need for external RC networks. The component is housed in a TO-220AB through-hole package, suitable for baseplate mounting. It operates within a junction temperature range of -40°C to 125°C and features standard recovery characteristics.

Triacs Feature Summary

• Snubberless operation eliminates requirement for external RC circuits
• High voltage blocking capability up to 1.2 kV
• Through-hole TO-220AB package facilitates thermal management

Triacs Applications

• Motor control systems
• Power supply units
• Industrial heating controllers

Triacs Procurement Notes

Verify the specific datasheet revision and manufacturer lot codes upon receipt. Confirm that the TO-220AB package dimensions match the intended PCB or chassis layout requirements. Ensure thermal interface materials are compatible with the baseplate for effective heat dissipation during high-current operation.

Triacs Selection Notes

Select this component for applications requiring high-voltage AC switching without external snubbers. The 8 A rating suits moderate power loads. Consider the TO-220AB form factor for ease of mechanical attachment to heatsinks. Evaluate thermal resistance requirements against the ambient operating conditions to ensure reliability within the specified temperature range.

Triacs Part Context

This part belongs to the Crydom Triac Alternistor series, designed for robust AC power control. Unlike standard TRIACs, these devices integrate internal structures to handle di/dt stresses, simplifying circuit design by removing external protection components. They are commonly used in industrial environments where reliability and reduced component count are priorities.
