Description

These Trisil series have been designed to protect telecommunication equipment against lightning and transient induced by AC power lines.

They are available in SMA, SMB and DO-15 packages.

Features

■ Bidirectional crowbar protection

■ Voltage range from 62 V to 320 V

■ Low capacitance from 12 pF to 20 pF @ 50 V

■ Low leakage current : IR = 2 µA max

■ Holding current: IH = 150 mA min

■ Repetitive peak pulse current :

IPP = 50 A (10/1000 µs)

Main applications

Telecommunication equipment such as:

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

ISDN, ...)

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

office equipment

SMTPA62属于电路保护 > TVS - 晶闸管。意法半导体（ST）集团制造生产的SMTPA62TVS - 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。
