LMSZ5262BT1G稳压二极管产品概述

LMSZ5262BT1G是乐山无线电(LRC)推出的独立式贴片稳压二极管,针对中高压稳压场景设计,以小封装(SOD-123)实现51V标称稳压、低漏电流、宽温适应等特性,适合高密度PCB设计及严苛环境下的电源/信号电路应用。

一、核心定位与关键特性

该器件属于中高压稳压二极管范畴,核心特点可概括为:

  1. 标称稳压值51V,公差±5%(实际范围48.45V~53.55V),满足中高压电路的稳定电压需求;
  2. 反向漏电流极低:39V测试条件下仅100nA,可有效降低电路待机功耗;
  3. 小功率设计:最大耗散功率500mW,适配小电流稳压场景;
  4. 宽温工作范围:结温-55℃~+150℃,覆盖工业级及部分汽车电子环境;
  5. SOD-123贴片封装:尺寸紧凑,支持高密度PCB布局,兼容常规表面贴装工艺。

二、电气参数深度解析

2.1 稳压特性

标称稳压值为51V,稳压范围由±5%公差决定(51V×5%=2.55V),实际工作中稳压值稳定在48.45V~53.55V区间,满足多数中高压电路的基准或稳压需求。

2.2 漏电流与功耗

  • 反向漏电流(Ir):39V偏置电压下仅100nA,远低于常规稳压二极管的漏电流水平,可减少电路静态损耗;
  • 最大耗散功率(Pd):500mW(0.5W),使用时需注意负载电流与稳压值的乘积不超过该值,避免器件过热损坏。

2.3 动态阻抗

  • Zzt(测试电流下的动态阻抗):125Ω,反映稳压值随测试电流变化的灵敏度;
  • Zzk(最大电流下的动态阻抗):1.1kΩ,需结合应用电流范围选择合适的限流电阻,确保稳压精度。

三、封装与物理特性

LMSZ5262BT1G采用SOD-123表面贴装封装,属于小型贴片封装(典型尺寸约1.6mm×0.8mm×0.5mm),具有以下优势:

  1. 尺寸紧凑:适合便携式设备、高密度PCB板的小空间布局;
  2. 独立式封装:便于单独使用,也可通过串联(提高稳压值)或并联(增大电流能力)扩展应用;
  3. 封装可靠性:SOD-123封装抗机械应力,兼容回流焊、波峰焊等常规贴片生产工艺,长期工作稳定性好。

四、典型应用场景

结合器件参数,LMSZ5262BT1G主要适用于以下场景:

  1. 小功率电源稳压:如DC-DC转换器输出稳压、线性电源的后级稳压,为后端电路提供稳定的50V左右电压;
  2. 模拟电路基准参考:作为运算放大器、ADC/DAC等模拟器件的基准电压源,低漏电流特性保证基准精度;
  3. 过压保护电路:配合限流电阻,在电路中实现过压钳位,保护MCU、传感器等敏感器件;
  4. 工业控制与仪表:宽温范围(-55℃~+150℃)适应工业现场的高低温环境,如温度传感器模块、PLC辅助电源;
  5. 消费电子便携设备:小封装适合智能穿戴、小型医疗设备的电源管理电路,满足空间与功耗要求。

五、可靠性与品牌保障

作为乐山无线电(LRC)的成熟产品,LMSZ5262BT1G具备可靠的质量保障:

  1. 宽温可靠性:结温范围覆盖工业级要求,通过高低温循环测试;
  2. 低漏电流一致性:批量生产中漏电流波动小,保证电路性能一致性;
  3. 封装兼容性:适配主流贴片设备,生产良率高;
  4. 品牌背书:LRC是国内知名半导体厂商,产品广泛应用于通信、工业、汽车等领域,技术支持完善。

总结:LMSZ5262BT1G是一款高性价比的中高压贴片稳压二极管,以小封装、低漏电流、宽温特性满足多场景稳压需求,适合对空间、功耗及可靠性有要求的电路设计。

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
