LTVS16H5.0AT5G ESD防护二极管产品概述

LTVS16H5.0AT5G是乐山无线电(LRC)推出的一款单向瞬态电压抑制(TVS)型ESD防护二极管,专为小型化、高密度电子设备的静电放电(ESD)防护设计,兼具小体积、低功耗、可靠防护的特点,适配多种消费电子、通信及物联网场景。

一、产品核心定位与用途

该器件属于单向ESD防护二极管,核心作用是在电子设备遭遇静电放电(如人体接触、设备插拔产生的ESD脉冲)时,快速导通并钳位电压,避免后端敏感电路(如MCU、传感器、射频模块等)因过压损坏。其设计目标是满足小型化设备的PCB空间限制,同时提供符合国际标准的防护能力。

二、关键性能参数解析

LTVS16H5.0AT5G的性能参数针对性强,可满足多数5V工作电压电路的防护需求:

  1. 极性与工作电压:单向防护,反向截止电压(Vrwm)为5V,即正常工作时电路反向电压不超过5V则器件处于截止状态,不影响电路功能;
  2. 防护触发特性:击穿电压6.5V(器件开始导通防护的阈值),钳位电压9.8V(ESD脉冲下能将电压稳定在该值以下,保护后端电路耐压);
  3. 静态功耗:反向漏电流(Ir)仅300nA,几乎不增加电路静态功耗,适合低功耗设备;
  4. 防护等级:符合IEC 61000-4-2国际ESD测试标准,可有效应对接触放电(典型8kV)、空气放电(典型15kV)场景;
  5. 寄生参数:结电容(Cj)800pF,在DFN小封装下控制合理,适配电源端、低速接口等对电容要求不苛刻的电路;
  6. 通道数:单路设计,适合单端信号或电源端口的独立防护。

三、封装与物理特性

器件采用DFN1610封装,属于无引脚扁平封装(DFN),尺寸为1.6mm×1.0mm(长×宽),厚度约0.5mm,具有以下优势:

  • 小体积:比传统SOT-23封装缩小约60%,大幅节省PCB布局空间,适配智能手机、可穿戴设备等小型化产品;
  • 低寄生:无引脚设计降低了寄生电感和电容,提升了ESD防护的响应速度;
  • 散热性:封装底部的散热焊盘可有效导出热量,保证器件在多次ESD冲击下的稳定性。

四、典型应用场景

LTVS16H5.0AT5G的小封装与针对性参数,使其适配以下场景:

  1. 消费电子:智能手机/平板的电源端口、按键接口、音频/Type-C接口防护;
  2. 可穿戴设备:智能手表、手环的充电端口、传感器输入防护;
  3. 通信模块:WiFi、蓝牙、LoRa等物联网模块的射频/数据接口防护;
  4. 工业控制:小型传感器节点、PLC输入输出端口的ESD防护(针对5V工作电压电路)。

五、产品优势与适配性总结

该器件的核心优势在于:

  • 品牌可靠性:LRC作为国内知名半导体厂商,产品一致性与供应稳定性强;
  • 成本效益:小封装设计降低了PCB成本,同时防护性能符合主流需求;
  • 场景适配:5V工作电压覆盖多数中低压电路,单向防护满足单端应用需求。

需注意,其800pF结电容不适合高速信号(如USB3.0、HDMI等)防护,更适配电源端、低速接口等场景。

综上,LTVS16H5.0AT5G是一款高性价比的单向ESD防护二极管,为小型化电子设备提供可靠的静电防护方案,有效提升设备在实际使用中的抗干扰能力与可靠性。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
