PTVS3-xxxC-TH Series High Current TVS Diodes
General Information
The Model PTVS3-xxxC-TH Series high current bidirectional TVS diodes are designed
for use in high power DC bus clamping applications. These devices offer bidirectional
port protection and are available with standoff voltage ratings of 58 V and 76 V.
The devices are RoHS* compliant and UL Recognized (pending). They also meet IEC
61000-4-5 8/20 μs current surge requirements.
