SMP80MC中文资料用于电信设备保护的Trisil™数据手册ST规格书

描述 Description

The SMP80MC is a series of micro capacitance transient surge arrestors designed for the protection of high debit rate communication equipment. Its micro capacitance avoids any distortion of the signal and is compatible with digital transmission like ADSL2 and ADSL2+.

特性 Features

• Bidirectional crowbar protection
• Voltage: range from 120 V to 320 V
• Low VBO/ VRratio
• Micro capacitance equal to 12 pF @ 50 V
• Low leakage current: IR= 2 μA max
• Holding current: IH= 150 mA min.
• Repetitive peak pulse current:IPP= 80 A (10/1000 μs)
• Benefits
•Trisils are not subject to ageing and provide a fail safe mode in short circuit for better protection.
•Helps equipment meet main standards such as UL60950, IEC 950 / CSA C22.2 and UL1459.
•Epoxy meets UL94, V0.
•Package is JEDEC registered (DO-214AA).
• Complies with the following standards
•GR-1089 Core
•ITU-T-K20/K21
•IEC 61000-4-5
•TIA/EIA IS-968
•UL497B recognized, UL file E136224

简介

SMP80MC属于电路保护的TVS-晶闸管。由制造生产的SMP80MCTVS - 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。
