MAIN APPLICATIONS Dedicated to dataline protection, this device provides a tripolar protection function. It ensures the same protection capability with the same breakdown voltage in both common and differential modes. DESCRIPTION The TPN3021 is a low capacitance transient surge arrestor designed for protection of high debit rate communication network. Its low capacitance avoids distorsion of the signal as it has been designed for T1/E1 and Ethernet networks. BENEFITS Trisil technology is not subject to ageing and provides a fail safe mode in short circuit for a better protection. They are used to help equipment to meet main standards such as UL1950, IEC950 / CSA C22.2 and UL1459. They have UL94 V0 approved resin. SO8 package is JEDEC registered. Trisils comply with the following standards GR-1089 Core, ITU-T-K20/K21, VDE0433, VDE0878, IEC61000-4-2.

D.U.T
This is a GO-NOGO test which allows to confirm the holding current (IH) level in a functional test circuit. Test procedure: 1- Adjust the current level at the IH value by short circuiting the DUT. 2- Fire the DUT with a surge current IPP = 10A, 10/1000 s. 3- DUT must come back in off state within maximum 50ns.
