LBZT52B4V7T1G稳压二极管产品概述

LBZT52B4V7T1G是乐山无线电(LRC)推出的一款小功率表面贴装稳压二极管,属于LBZT52B系列,专为各类电子设备的电压基准、稳压滤波等场景设计,兼具宽温适应性与高可靠性,是工业、消费电子领域的常用选型。

一、产品品牌与核心定位

乐山无线电(LRC)是国内半导体行业的老牌厂商,拥有数十年分立器件研发生产经验,产品覆盖二极管、三极管等多个品类,符合RoHS无铅环保标准,广泛应用于汽车电子、工业控制、通信等领域。LBZT52B4V7T1G作为该品牌的稳压二极管代表型号,针对小功率电路的稳压需求优化,主打高性价比、宽温稳定、小型化封装三大特点,适配高密度PCB设计。

二、关键电气参数深度解析

该型号的核心电气参数直接决定了其应用场景,具体解析如下:

  1. 稳压特性:标称稳压值为4.7V,稳压范围覆盖4.55V~4.75V(误差±3%),满足大多数常规电路的稳压精度要求;反向漏电流(Ir)仅2μA(测试条件:反向电压1.0V),远低于同类产品平均水平,有效降低待机功耗。
  2. 功率与阻抗:最大耗散功率(Pd)为500mW,支持小功率电路的连续工作;动态阻抗分为两个测试条件:Zzt=100Ω(典型测试电流下)、Zzk=800Ω(典型测试电压下),其中低Zzt值确保稳压性能稳定,适合对电压波动敏感的电路(如传感器基准)。
  3. 温度适应性:工作结温范围覆盖-55℃~+150℃,可应对极端高低温环境(如北方户外设备、高温工业车间),无需额外散热设计即可稳定工作。

三、封装与物理特性

采用SOD-123小型表面贴装封装,尺寸紧凑(典型值:1.6mm×0.8mm×0.8mm),适合高密度PCB布局,节省电路板空间;封装引脚采用镀锡工艺,焊接兼容性好,回流焊温度(260℃以下)符合行业标准,无铅环保且抗腐蚀性能优异。

四、典型应用场景

LBZT52B4V7T1G的参数特性使其适配多类场景:

  • 消费电子:手机、平板、智能穿戴设备的电源稳压模块、信号基准源;
  • 工业控制:PLC(可编程逻辑控制器)、传感器模块的电压基准、抗干扰滤波;
  • 汽车电子:车载中控、传感器电路的辅助稳压(宽温适配满足车载环境);
  • 通信设备:小型基站、路由器的电源辅助稳压、偏置电路。

五、使用注意事项

为确保产品性能稳定,需注意以下要点:

  1. 工作电流限制:最大允许工作电流需结合耗散功率计算(Imax≈500mW/4.7V≈106mA),实际使用需预留30%~50%余量,避免过流损坏;
  2. 温度漂移补偿:稳压值随结温存在轻微漂移(典型值0.05%/℃),若需高精度稳压,可结合电路设计补偿;
  3. 焊接规范:SOD-123封装需采用合适的回流焊/波峰焊参数,避免过热导致封装变形;
  4. ESD防护:虽然稳压管具备一定ESD防护能力,但焊接前需采取防静电措施(如接地工作台)。

综上,LBZT52B4V7T1G凭借稳定的稳压性能、宽温适应性与小型化封装,成为LRC在小功率稳压领域的经典型号,可满足多行业的常规稳压需求,是电子设计中可靠的选型方案。

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
