DESCRIPTION

The SMP100LC-xxx series is a very low capacitance transient surge arrestor designed for the protection of high debit rate communication equipment. Its low capacitance avoid any distorsion of the signal.

FEATURES

■ Bidirectional crowbar protection

■ Low capacitance : C = 30 PF TYP @ 50V

■ Low leakage current : IR = 2 μA MAX

■ Repetitive peak pulse current : IPP = 100 A (10/1000μS)

■ Holding current: IH = 150 mA

BENEFITS

■ No ageing and no noise

■ Short circuit in failure mode, thus still ensuring protection

■ Board space saving

MAIN APPLICATIONS

Any sensitive equipment requiring protection against lightning strikes and power crossing:

■ Analog and digital line cards (xDSL, T1/ E1, ISDN...)

■ Gas tube replacement

■ Terminals and transmission equipment

SMP100LC-270屬于電路保護 > TVS - 晶閘管。意法半導(dǎo)體（ST）集團制造生產(chǎn)的SMP100LC-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(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。
