Bourns, Inc. today announced a significant expansion of the company's high-voltage Power Transient Voltage Suppressor (PTVS) product line. Offering superior bidirectional port protection from 170V to 430Vs, the nine new PTVS devices are designed to meet stringent IEC 61000-4-5 8/20 µs current surge requirements in a broad variety of ac line and high-power dc clamping applications such as those in exposed ac-dc power supplies in outdoor environments.
An advantage for customers is that PTVS silicon-based technology delivers lower clamping voltage under surge, greater performance stability and increased reliability compared to the capabilities offered from typical competing MOV technology. The Bourns® PTVS products also offer an excellent surge response versus temperature; the typical maximum surge current at 150 degrees C exceeds 70 % of their rated value at 25 degrees C.
