Bourns PTVS1-380C-TH series high power TVS (PTVS) diodes

Bourns is pleased to announce the release of a 1 kA, 380 V bidirectional high current Power TVS Diode, extending the existing range of the PTVS series. The Model PTVS1-380C-TH was designed for use in AC bus clamping applications.

The Bourns® Model PTVS1 Series offers bidirectional port protection meeting IEC 61000-4-5 8/20 μs current surge requirements and is RoHS compliant* and halogen free**. Compared to typical competing MOV technology, the use of silicon technology in the Power TVS products provides a
lower clamping voltage under surge, greater performance stability and increased reliability.

These devices exhibit an excellent surge response versus temperature; the maximum surge current at +150 °C exceeds 70 % of their rated value at +25 °C.

Features

• Very high surge current protection (1 kA @ +25 °C)
• Low clamping voltage under surge
• Excellent performance over temperature
• RoHS compliant* and halogen free**

Applications

• AC line protection
• Protection of power supplies used in exposed and harsh environments
• SPD and dongles

_{* RoHS Directive 2011/65/EU and amendment of Annex II. 
** Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.}
