LCP02-150M-TR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LCP02-150M-TRTVS - 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 LCP02-150M has been developed to protect SLICs operating on both negative and positive supplies, as well as on high voltage SLICs. It provides crowbar mode protection for both TIP and RING lines. Surge suppression is assumed for each wire by two thyristor structures, one dedicated to positive surges, the second one to negative surges. Both positive and negative threshold levels are programmable by two gates (Gn and Gp). The use of transistors decreases the battery currents during surge suppression.
