DESCRIPTION

The SMP50-xxx series has been designed to

protect telecommunication equipment against

lightning and transient induced by AC power lines.

The package / die size ratio has been optimized by

using the SMA package.

FEATURES

■ Bidirectional crowbar protection

■ Voltage range from 62V to 270V

■ Low capacitance from 15pF to 30pF typ.@ 50V

■ Low leakage current: IR = 2μA max.

■ Holding current: IH = 150 mA min.

■ Repetitive peak pulse current:

IPP = 50 A (10/1000 μs)

SMP50-270屬于電路保護 > TVS - 晶閘管。意法半導體（ST）集團制造生產的SMP50-270TVS - 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。
