LBZX84C47LT1G稳压二极管产品概述

一、产品核心身份与定位

LBZX84C47LT1G是乐山无线电(LRC)推出的表面贴装稳压二极管,属于LBZX84C系列标准稳压管,专为小功率直流稳压、电压基准及过压保护场景设计。其采用SOT-23紧凑封装,适配高密度PCB布局,可满足便携式设备、工业控制、传感器模块等多领域的低功耗稳压需求。

二、关键电性能参数详解

该产品的核心电性能围绕“稳压精度、功耗控制、温宽适应性”三大维度设计,具体参数如下:

(1)稳压特性

  • 标称稳压值:47V(典型应用下的目标稳压电压);
  • 稳压范围:44V~50V(允许的电压波动范围,覆盖±6.4%容差,满足常规电路稳压需求);
  • 动态阻抗:170Ω(稳压状态下电压随电流变化的斜率,数值越小稳压性能越稳定,说明工作电流波动时输出电压波动极小)。

(2)功耗与反向特性

  • 最大耗散功率(Pd):300mW(可承受的最大功耗,适合小功率电路——如5V供电下串联1kΩ电阻时,最大电流约30mA,满足多数低压控制电路需求);
  • 反向漏电流(Ir):仅50nA(反向截止状态下的漏电流,比普通稳压管μA级别漏电流低两个数量级,静态功耗可忽略,适配电池供电设备)。

(3)温度适应性

工作结温范围:-55℃~+150℃(宽温覆盖工业级要求,可在户外低温、设备高温环境下稳定运行,无需额外散热设计)。

三、封装与物理特性

LBZX84C47LT1G采用SOT-23封装(TO-236AB),属于小型表面贴装封装,具备以下优势:

  • 尺寸紧凑:标准尺寸约0.8mm(宽)×1.3mm(长)×1.0mm(高),显著节省PCB空间,适配便携式设备小型化设计;
  • 焊接兼容性:3引脚设计符合常规贴装工艺,支持回流焊、波峰焊,焊接可靠性高;
  • 环保合规:符合RoHS 2.0及无卤素要求,满足全球电子设备环保标准。

四、典型应用场景

结合参数特性,该产品适用于以下场景:

  1. 小功率稳压电路:作为单片机、MCU的辅助稳压电源,或传感器模块的基准电压源(如47V基准适配高压信号采集);
  2. 过压保护电路:与限流电阻串联,输入电压超47V时导通,钳位电压在44V~50V范围内,保护后级电路;
  3. 低功耗电压基准:用于ADC、DAC的参考电压(50nA漏电流不影响系统续航,稳压范围稳定保证采样精度);
  4. 工业控制模块:宽温范围适配户外监测、电机控制等工业现场高低温环境。

五、品牌与质量保障

乐山无线电(LRC)是国内半导体老牌厂商,具备50+年分立器件研发生产经验,LBZX84C47LT1G的质量优势如下:

  • 批量一致性:参数偏差严格控制在规格内(稳压范围44V~50V、漏电流≤50nA),批量采购无需额外筛选;
  • 可靠性认证:符合工业级要求,部分批次通过AEC-Q101汽车级认证(汽车应用需确认具体批次);
  • 技术支持:提供完整datasheet及电路设计协助,覆盖选型、降额计算等需求。

六、选型与使用注意事项

  1. 功耗限制:实际应用需计算电路功耗,确保不超300mW(公式:I×V_z ≤300mW,I为工作电流,V_z为稳压值);
  2. 温度降额:结温超25℃时,按Pd=300mW×(150℃-Tj)/125℃降额(Tj为实际结温);
  3. 焊接温度:回流焊峰值温度≤260℃(持续≤10秒),避免损坏器件。

该产品以“高稳定性、低功耗、宽温适应性”为核心,是小功率稳压场景的高性价比选择。

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
