MMSZ5234B_R1_00001 稳压二极管产品概述

一、产品基本信息

MMSZ5234B_R1_00001是PANJIT(强茂) 推出的一款独立式稳压二极管,采用SOD-123小型表面贴装封装,专为中小功率电路的稳压、基准电压生成及过压保护设计。该型号属于通用型稳压管,配置为独立单管,无并联/串联结构,便于电路灵活布局。

二、核心电气性能参数

1. 稳压特性

  • 标称稳压值:6.2V(行业常用基准电压值,兼容多数模拟电路需求);
  • 稳压范围:5.89V~6.51V(偏差±5%,满足批量应用中电压一致性要求);
  • 反向漏电流:5uA@4V(低漏电流设计,静态功耗极低,适合电池供电设备)。

2. 功率与阻抗

  • 最大耗散功率:500mW(连续工作时需降额使用,峰值功耗不超过此值);
  • 动态阻抗:Zzt=7Ω(稳压区交流阻抗,负载变化时电压波动小,稳压精度高);
  • 反向击穿区阻抗:Zzk=1kΩ(反向击穿初期阻抗特性,可辅助过压保护响应)。

3. 温度适应性

  • 工作结温范围:-55℃~+150℃(覆盖工业级、汽车级极端环境,例如汽车发动机舱、户外传感器模块等场景)。

三、典型应用场景

该稳压管因尺寸小、功耗低、宽温稳定,广泛应用于以下领域:

  1. 消费电子:手机、平板、智能穿戴设备的充电模块稳压、USB接口过压保护;
  2. 工业控制:PLC(可编程逻辑控制器)、温度/压力传感器的基准电压源,小型电机驱动电路稳压;
  3. 汽车电子:车载导航、仪表盘、倒车雷达的辅助电源稳压(适配车载12V系统);
  4. 通信设备:小型基站、路由器、光模块的电源滤波稳压,避免电压波动影响信号传输。

四、产品关键优势

  1. 稳压精度可靠:±5%的稳压偏差范围,批量应用中电压一致性好,无需额外校准;
  2. 低功耗适配电池设备:反向漏电流仅5uA@4V,静态功耗可忽略,延长电池续航时间;
  3. 宽温稳定耐用:-55℃~+150℃的结温范围,满足工业、汽车等极端环境的可靠性要求;
  4. 小型化设计:SOD-123封装尺寸(约2.0mm×1.2mm),节省PCB空间,适合高密度电路布局;
  5. 成本效益突出:强茂成熟工艺下的性价比产品,适合大规模量产应用。

五、选型与使用注意事项

  1. 功率匹配:连续工作时需确保电路功耗不超过500mW(例如负载电流100mA时,功耗=6.2V×100mA=620mW,需降额至80%以下,即负载电流≤80mA);
  2. 焊接规范:SOD-123封装的回流焊峰值温度不超过260℃,焊接时间≤10秒,避免热损伤;
  3. 静电防护:稳压管为静电敏感元件,存储/焊接时需使用防静电包装与工具;
  4. 过压保护搭配:若用于过压保护,需串联限流电阻(例如12V系统中,串联1kΩ电阻可限制击穿电流≤12mA)。

该型号凭借稳定的电气性能与灵活的应用场景,成为中小功率稳压电路的优选元件,尤其适合对尺寸、功耗、宽温要求较高的电子设备设计。

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
