描述 Description

This device has been designed to protect 2 new high voltage, as well as classical SLICs against transient overvoltages.
Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -VBATthrough the gate.
This component presents a very low gate triggering current (IGT) to reduce the current consumption on printed circuit boards during the firing phase.

特性 Features

? dual-line programmable transient voltage suppressor
? wide negative firing voltage range
? VMGL= -150 V max.
? low dynamic switching voltages: VFPand VDGL
? low gate triggering current: IGT= 5 mA max.
? peak pulse current: IPP= 20 A (10/1000 μs)
? holding current: IH= 150 mA min.
? Benefits
? A Trisil? is not subject to ageing and provides a fail safe mode in short circuit for better protection.
? Trisils are used to help equipment meet various standards such as UL1950, IEC 950 / CSA C22.2, UL1459 and FCC part68.
? Trisils have UL94 V0 approved resin.
? Trisils are UL497B approved (file: E136224).

簡(jiǎn)介

LCDP1521屬于電路保護(hù)的TVS-晶閘管。由制造生產(chǎn)的LCDP1521TVS - 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(guò)壓保護(hù)，在正常工作條件下近似于開(kāi)路。在這些器件兩端施加超過(guò)某個(gè)特定值的電壓（稱(chēng)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(guò)器件的電流因電路中的一些外部影響而降低到稱(chēng)為“保持電流”的最小值以下。
