CTB12-1200TWPT

Triacs Overview

The CTB12-1200TWPT is a standard Triac manufactured by Sensata-Crydom, designed for single-phase AC power control applications. It features a 1.2 kV repetitive peak off-state voltage rating and is housed in a TO-220AB through-hole package. The device supports an operating junction temperature range of -40°C to 125°C. Non-repetitive surge current capabilities are specified at 160A for 50Hz and 168A for 60Hz frequencies. This component is part of the broader Crydom discrete semiconductor portfolio.

Triacs Feature Summary

• Standard Triac configuration for general-purpose AC switching
• Robust thermal performance with high junction temperature tolerance
• Through-hole mounting for secure mechanical integration

Triacs Applications

• AC motor speed control circuits
• Solid state relay output stages
• Industrial heating element regulation

Triacs Procurement Notes

Verify the specific suffix 'TWPT' against official Sensata-Crydom documentation to confirm pinout and packaging variations. Confirm RoHS compliance status as required by project specifications. Ensure the obsolete status indicated in distributor databases is reconciled with current manufacturer availability before finalizing procurement plans.

Triacs Selection Notes

Select this component when a rugged, through-hole Triac with 1.2 kV blocking capability is required. Evaluate the thermal management requirements given the TO-220AB package constraints. Compare surge current ratings against load inrush characteristics to ensure adequate safety margins during startup conditions.

Triacs Part Context

This Triac belongs to the Sensata-Crydom discrete semiconductor line, distinct from their solid-state relay assemblies. It serves as a fundamental switching element within larger power electronics systems. The M50 series modules represent a different form factor and application scope compared to this individual TO-220 packaged device.
