LBZX84B18LT1G稳压二极管产品概述

LBZX84B18LT1G是乐山无线电(LRC)推出的一款小功率表面贴装稳压二极管,专为低功耗、高密度电路设计提供稳定的18V电压基准,具备低漏电流、高精度稳压、紧凑封装等核心优势,广泛适配便携电子、工业控制、传感器模块等场景。

一、产品基本信息与品牌依托

LBZX84B18LT1G隶属于LRC稳压二极管产品线,LRC作为国内半导体行业老牌厂商,专注功率器件、稳压管研发生产超50年,产品以一致性好、可靠性高著称,覆盖消费电子、汽车电子、工业控制等领域。该产品采用独立式单管封装,核心功能是反向击穿状态下输出稳定的18V电压,属于小信号稳压二极管范畴。

二、核心电气参数深度解析

关键参数直接决定应用适配性,该产品参数经过严格测试:

  1. 稳压值特性:标称18V,实际范围17.56V~18.35V(±2%精度),满足多数电路对稳压精度的要求,避免信号误差。
  2. 反向漏电流:反向电压13V时漏电流仅100nA,远低于常规稳压管,显著降低待机功耗,适配电池供电设备。
  3. 最大耗散功率:额定225mW,结合18V稳压值计算最大稳压电流约12.5mA,覆盖小信号电路(如传感器、ADC参考电压)需求。
  4. 动态阻抗:测试电流下Zzt=65Ω,拐点电流下Zzk=80Ω,阻抗稳定且偏低,输出电压随负载波动小,稳压性能可靠。
  5. 独立式配置:单管设计,可单独使用或并联(匹配电流)扩展稳压电流,适配不同功率需求。

三、封装与物理特性

采用SOT-23小型表面贴装封装,具备以下优势:

  • 尺寸紧凑:约2.9mm×1.6mm×1.1mm,仅为插件二极管1/5,节省PCB空间,适配智能手机、智能穿戴等高密度设计。
  • 引脚配置:3引脚设计,1脚为阴极(接正电压),2、3脚为阳极(接地),安装需注意极性。
  • 宽温适应性:参考LRC同类产品,支持-55℃~150℃工作温度,适配工业高温(如PLC模块)或低温户外场景(如智能传感器)。

四、典型应用场景梳理

基于特性,主要应用于:

  1. 便携电子稳压:智能手环、蓝牙耳机的电压基准,低漏电流延长电池续航,紧凑封装适配小主板。
  2. 传感器参考电压:工业温度/压力传感器的ADC前级稳压,稳定18V保证信号采集精度,避免电压波动影响测量。
  3. 电源辅助稳压:LDO输出后串联/并联,抑制纹波,提升电源稳定性(适配对纹波敏感电路)。
  4. 小电流过压保护:结合限流电阻,输入电压超18V时击穿导通,钳位电压保护后级MCU、传感器(需匹配限流电阻防过载)。

五、性能优势总结

核心竞争力:

  • 低功耗:100nA反向漏电流,适合电池供电,降低待机消耗。
  • 高精度:±2%稳压范围,满足工业/消费级电路精度需求。
  • 高集成:SOT-23封装适配小型化设计趋势。
  • 可靠品质:LRC工艺成熟,批量一致性好,降低不良率。

综上,LBZX84B18LT1G是性价比高、适配性强的小功率稳压二极管,满足多数低功耗、高精度电路的稳压与电压基准需求。

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
