SMP100LC-270電路保護(hù)的TVS-晶閘管規(guī)格書(shū)PDF中文資料

SMP100LC-270屬于電路保護(hù)的TVS-晶閘管。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的SMP100LC-270TVS - 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(guò)壓保護(hù)，在正常工作條件下近似于開(kāi)路。在這些器件兩端施加超過(guò)某個(gè)特定值的電壓（稱為擊穿電壓），可使它們進(jìn)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(guò)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 SMP100LC is a series of low capacitance transient surge arrestors designed for the protection of high data rate communication equipment. Its low capacitance avoids any distortion of the signal and is compatible with digital transmission line cards (xDSL, ISDN...). SMP100LC series tested and confirmed compatible with Cooper Bussmann Telecom Circuit Protector TCP 1.25A.

Features

■ Bidirectional crowbar protection

■ Voltage range from 8 V to 400 V

■ Low capacitance from 20 pF to 45 pF @ 50 V

■ Low leakage current : IR= 2 μA max

■ Holding current: IH= 150 mA min

■ Repetitive peak pulse current: IPP= 100 A (10/1000 μs)

Main applications

Any sensitive equipment requiring protection against lightning strikes and AC power faults. These devices are dedicated to central office protection as they comply with the most stressfull standards. Their Low Capacitances make them suitable for xDSL.
