PTVS3-xxxC Series High Current TVS Diodes
General Information
The PTVS3-xxxC range of high current bidirectional TVS diodes is
designed for use in AC line protection and high power DC bus
clamping applications. These devices offer bidirectional port protection
from 380 volts to 430 volts.
The devices are RoHS* and UL compliant while also meeting IEC
61000-4-5 8/20 µs current surge requirements.
