SMP30-130电路保护的TVS-晶闸管规格书PDF中文资料

SMP30-130属于电路保护的TVS-晶闸管。由意法半导体集团制造生产的SMP30-130TVS - 晶闸管基于晶闸管的瞬态电压抑制 (TVS) 器件可用于提供过压保护，在正常工作条件下近似于开路。在这些器件两端施加超过某个特定值的电压（称为击穿电压），可使它们进入近似于短路的导通状态。?这种状态一直持续至流过器件的电流因电路中的一些外部影响而降低到称为“保持电流”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.
