This three-chip SIDACtor solution offers a guaranteed balanced protection, based on a Littelfuse patent (US Patent 4,905,119). The ‘Y’ configuration offers identical metallic and longitudinal protection in one through-hole modified TO-220 package. For primary protection applications, devices with higher holding current and integrated failsafe options are available.

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).

P1803A_L屬于電路保護(hù) > TVS - 晶閘管。力特公司制造生產(chǎn)的P1803A_LTVS - 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(gè)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。
