DO-214AA SIDACtor solid state protection devices with a D surge rating protect telecommunications equipment located in hostile environments. These SIDACtor devices withstand the simultaneous surges outlined in GR 1089 lightning tests. (See “First Level Lightning Surge Test” on page 7-5.) Surge ratings are twice that of a device with a C surge rating. This provides a method for building an SMT version of the balanced ‘Y’ configuration. (US Patent 4,905,119) SIDACtor devices enable equipment to comply with various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968-A (formerly known as FCC Part 68).

P1500SDL屬于電路保護 > TVS - 晶閘管。力特公司制造生產(chǎn)的P1500SDLTVS - 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。
