TPN3021RL電路保護的TVS-晶閘管規(guī)格書PDF中文資料

TPN3021RL屬于電路保護的TVS-晶閘管。由意法半導體集團制造生產(chǎn)的TPN3021RLTVS - 晶閘管基于晶閘管的瞬態(tài)電壓抑制 (TVS) 器件可用于提供過壓保護，在正常工作條件下近似于開路。在這些器件兩端施加超過某個特定值的電壓（稱為擊穿電壓），可使它們進入近似于短路的導通狀態(tài)。?這種狀態(tài)一直持續(xù)至流過器件的電流因電路中的一些外部影響而降低到稱為“保持電流”的最小值以下。

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.

Features

■ Triple crowbar protection

■ Low capacitance

■ Low holding current: IH = 30 mA minimum

■ Surge current:

– IPP = 200 A, 2/10 μs

– IPP = 30 A, 10/1000 μs

Main applications

Dedicated to data line 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.

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 ap-proved resin. SO8 package is JEDEC registered.

Trisils comply with the following standards GR-1089 Core, ITU-T-K20/K21, VDE0433, VDE0878, IEC61000-4-2.
