Description

These Trisil series have been designed to protect telecommunication equipment against lightning and transient induced by AC power lines.

They are available in SMA, SMB and DO-15 packages.

Features

■ Bidirectional crowbar protection

■ Voltage range from 62 V to 320 V

■ Low capacitance from 12 pF to 20 pF @ 50 V

■ Low leakage current : IR = 2 μA max

■ Holding current: IH = 150 mA min

■ Repetitive peak pulse current :

IPP = 50 A (10/1000 μs)

Main applications

Telecommunication equipment such as:

■ Analog and digital line cards (xDSL, T1/E1,

ISDN, ...)

■ Terminals (phone, fax, modem, ...) and central

office equipment

TPA100屬于電路保護 > TVS - 晶閘管。意法半導(dǎo)體（ST）集團制造生產(chǎn)的TPA100TVS - 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(dǎo)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。
