SMP30-180屬于電路保護(hù)的TVS-晶閘管。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的SMP30-180TVS - 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。

描述 Description

The SMP30 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.

特性 Features

■ Bidirectional crowbar protection

■ Voltage range from 62 V to 270 V

■ Low capacitance from 10 pF

to 20 pF typ.@ 50 V

■ Low leakage current: IR = 2 μA max.

■ Holding current: IH = 150 mA min.

■ Repetitive peak pulse current:

IPP = 30 A (10/1000 μs)

Benefits

■ Trisils are not subject to ageing and provide a

fail safe mode in short circuit for a better

protection.

■ This device can be used to help equipment

meet various standards such as UL1950,

IEC950 / CSA C22.2, UL1459 and FCC part

68.

■ Trisils have UL94 V0 approved resin.

■ SMA package is JEDEC registered

(DO-214AC).

■ Trisils are UL497B approved (file: E136224).

Applications

Telecommunication equipment such as:

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

ISDN...).

■ Terminals (phone, fax, modem...) and central

office equipment.
