SMP2300SCMC屬于電路保護的TVS-晶閘管。由意法半導(dǎo)體集團制造生產(chǎn)的SMP2300SCMCTVS - 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。

描述 Description

The devices in the SMP-0SCMC series are micro capacitance Trisils designed to protect broadband telecommunication equipment such as DSL modems, subscriber gateways and DSLAMs from lightning surges and power faults.

Trisils are not subject to aging and provide a failsafe mode in short circuit for a better protection. They are used to help equipment to meet main standards such as UL60950, IEC950 / CSA C22.2and UL1459.

The SMP-0SCMC series is packaged in SMB.
