LCP02-150M电路保护的TVS-晶闸管规格书PDF中文资料

LCP02-150M属于电路保护的TVS-晶闸管。由意法半导体集团制造生产的LCP02-150MTVS - 晶闸管基于晶闸管的瞬态电压抑制 (TVS) 器件可用于提供过压保护，在正常工作条件下近似于开路。在这些器件两端施加超过某个特定值的电压（称为击穿电压），可使它们进入近似于短路的导通状态。?这种状态一直持续至流过器件的电流因电路中的一些外部影响而降低到称为“保持电流”的最小值以下。

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.
