MMSZ5237BS_R1_00001稳压二极管产品概述

一、产品基本信息

MMSZ5237BS_R1_00001是PANJIT(强茂)推出的表面贴装稳压二极管,型号对应8.2V标称稳压值,采用SOD-323超小型封装,属于工业级通用稳压器件,可满足多数电子电路对电压稳定、过压保护的需求。

二、关键电气参数解析

该器件的核心参数直接决定应用场景与性能表现,具体解析如下:

  1. 稳压值:标称8.2V,实际工作范围为7.79V~8.61V(±5%精度),覆盖常规电路对电压稳定度的要求;
  2. 反向漏电流(Ir):反向偏置电压6.0V时,漏电流仅3uA,低漏电流特性适配低功耗场景,减少待机损耗;
  3. 耗散功率(Pd):最大允许功率200mW,结合标称稳压值计算,最大工作电流约24.4mA(Pd/Vz),需注意电路限流;
  4. 动态阻抗:稳压状态下(Zzt)为8Ω,反向击穿前(Zzk)为500Ω,低动态阻抗可降低电压随电流的波动,提升稳压精度;
  5. 工作结温范围:支持**-55℃~+150℃**宽温区间,可适应极端环境(如高温工业、低温户外设备)。

三、封装与物理特性

采用SOD-323封装(尺寸约1.6mm×0.8mm×0.6mm,以官方 datasheet 为准),具有以下优势:

  • 体积超小,适配高密度PCB布局,满足便携设备(手机、智能穿戴)的小型化需求;
  • 表面贴装工艺,兼容自动化生产线,提升生产效率;
  • 封装可靠性高,抵抗机械应力与环境腐蚀能力强,延长器件寿命。

四、核心性能优势

  1. 低功耗适配:3uA反向漏电流,在电池供电设备中几乎无额外损耗;
  2. 宽温稳定:-55℃~+150℃结温范围,覆盖工业级与汽车级部分应用场景;
  3. 高精度稳压:8Ω低动态阻抗,稳压值波动极小,可作为精准电压基准;
  4. 小尺寸集成:SOD-323封装大幅缩小占用空间,便于电路紧凑设计。

五、典型应用场景

  1. 便携电子:智能手机、智能穿戴的电压基准或过压保护;
  2. 小型电源:低功率开关电源、线性电源的输出稳压环节;
  3. 汽车电子:车载小功率电路(仪表盘背光、传感器供电)的电压稳定;
  4. 工业控制:PLC、传感器模块的电压基准与过压防护;
  5. 通信设备:小型基站、无线模块的信号钳位与电压稳定。

六、使用注意事项

  1. 电流限制:最大工作电流约24.4mA,电路需串联限流电阻,避免过流损坏;
  2. 温度管控:结温不得超过150℃,高温环境需考虑散热设计;
  3. 参数区分:3uA漏电流为反向偏置6V时的指标,非稳压工作状态电流;
  4. 焊接规范:表面贴装焊接需遵循SOD-323封装的温度/时间要求,避免热损伤。

该器件凭借稳定的电气性能、小尺寸与宽温适应性,成为便携电子、工业控制等领域的优选稳压器件。

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
