LCP1521SRL電路保護的TVS-晶閘管規(guī)格書PDF中文資料

LCP1521SRL屬于電路保護的TVS-晶閘管。由意法半導體集團制造生產的LCP1521SRLTVS - 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，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特定值的電壓（稱為擊穿電壓），可使它們進入近似于短路的導通狀態(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。

Description

These devices have been especially designed to protect 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 -VBAT through the gate.

Features

■ Dual programmable transient 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= 30 A (10/1000 μs)

■ Holding current: IH= 150 mA min

■ Low space consuming package
