描述 Description

The SMP80MC is a series of micro capacitance transient surge arrestors designed for the protection of high debit rate communication equipment. Its micro capacitance avoids any distortion of the signal and is compatible with digital transmission like ADSL2 and ADSL2+.

簡介

SMP80MC屬于電路保護(hù)的TVS-晶閘管。由制造生產(chǎn)的SMP80MCTVS - 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(hù)，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(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。
