TPN3021 ® Application Specific Discretes A.S.D.™ TRIPOLAR OVERVOLTAGE PROTECTION FOR NETWORK INTERFACES FEATURES Triple crowbar protection Low capacitance Low holding current: IH = 30mA minimum Surge current: IPP = 200A, 2/10µs IPP = 30A, 10/1000µs ■ ■ ■ ■ 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.
