LCP02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LCP02TVS - 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。

特性 Features

? Protection IC recommended for ringing SLICs

? Wide firing voltage range: -120 V to +120 V

? Low gate triggering current: IG = 5 mA max

? Peak pulse current: IPP = 30 A (10/1000 μs)

? Holding current: IH = 150 mA min.

描述 Description

The LCP02 has been developed to protect SLICs

operating on both negative and positive battery

supplies, as well as high voltage SLICs. It

provides crowbar mode protection for both TIP

and RING lines. The surge suppression is

assumed for each wire by two thyristor structures,

one dedicated to positive surges the second one

for negative surges. Both positive and negative

threshold levels are programmable by two gates.

LCP02 can be used to help equipment to meet

various standards such as UL1950, IEC 60950 /

CSAC22.2, UL1459 and TIA-968-A. LCP02

pinout and clearance is compatible with UL60950.

Resin meets UL94 V0.

LCP02 is UL497B approved - file: E136224.
