LCP1531数据手册电路保护的TVS-晶闸管规格书PDF

描述 Description

These devices are ideally suited to meet the protection requirement of VoIP SLICs located in next generation residential gateways. They can be used for protecting any ringing SLIC since they meet the protection standard requirements.

Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to -VBATthrough the gate.

These components present a very low gate triggering current (IGT) to reduce the current consumption on printed circuit board during the firing phase.

特性 Features

• Dual programmable transient suppressor
• Wide negative firing voltage range:VGn= -175 V max.
• Low dynamic switching voltages:VFPand VDGL
• Low gate triggering current: IGT= 5 mA max
• Peak pulse current: IPP= 37.5 A (5/310 μs)
• Holding current: IH= 150 mA min.
• Low space consuming package
• 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 to meet various standards such as YDT695, GR-1089 and ITU-T K20/21.
•Trisils are UL94 V0 resin approved and are UL497B approved [file: E136224]).

简介

LCP1531属于电路保护的TVS-晶闸管。由制造生产的LCP1531TVS - 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。
