Thyristors & ACSwitches

STMicroelectronics has extended the junction temperature range of the BTA/BTB Snubberless Triacs to 150 °C, enhancing at the same time the dynamic characteristics. These new HiTj Triacs, together with the new ACST2, ACST10 and ACST12 autoprotected devices and the STCC08 power driver with diagnostic, ensure safer and higher-performance applications with competitive solutions.
With the HiTj Triacs, the resulting smaller heatsink and smaller packages for the delivered current will contribute to cost savings, while immune devices and systems will lower maintenance costs and increase customer fidelity.

Higher-immunity switches:

 
Improved power density with High Temperature Triacs
Increased safety: protection embedded and compliant with IEC 61000 standards with ACS and ACST devices
System integration: the new STCC (ST AC control circuit) and CLT/PCLT (programmable current limited I/O termination) series are smart AC switches and simplify FMEA tasks for modern designs.
