LCP1521SRL电路保护的TVS-晶闸管规格书PDF中文资料

LCP1521SRL属于电路保护的TVS-晶闸管。由意法半导体集团制造生产的LCP1521SRLTVS - 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

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.

特性 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
