MMSZ5236A_R1_00301 产品概述

一、产品概述

MMSZ5236A_R1_00301 是 PANJIT(强茂)出品的一款小功率稳压二极管,采用 SOD-123 表面贴装封装,适用于对体积和成本有严格要求的电压稳压与保护电路。该器件标称稳压值为 7.5V,工作温度范围宽(结温 -50℃ 至 +150℃),在通信、消费电子和工业控制等领域可作为基准稳压、浪涌钳位或参考元件使用。器件为未分类小信号稳压二极管,具有低反向电流与稳健的低功耗特性。

二、主要特点

  • 标称稳压值:7.5V;稳压范围:7.35V ~ 7.65V,稳压精度高,适合对电压要求较严的应用。
  • 耐温性能优异:工作结温范围 -50℃ ~ +150℃,适合宽温度环境。
  • 低反向电流:Ir = 3 μA @ 6.0V,有利于低泄漏场合的稳定性与低静态能耗。
  • 小功率耗散:Pd = 500 mW,适用于小电流稳压与信号电路。
  • 动态阻抗:Zzt = 6 Ω(测试工况下的稳态阻抗),提供良好的稳压特性;另有 Zzk = 500 Ω(低电流“膝”区阻抗),有利于快速描述低电流时曲线陡峭度。
  • 封装:SOD-123,体积小、易于高速贴片生产与自动装配。

三、电气与热参数(摘要)

  • 稳压值(标称):7.5V
  • 稳压值范围:7.35V ~ 7.65V
  • 反向电流(Ir):3 μA @ 6.0V
  • 耗散功率(Pd):500 mW(环境温度与散热条件影响额定耗散,请参考厂方完整技术手册做热设计)
  • 动态阻抗:Zzt = 6 Ω(稳态工作区),Zzk = 500 Ω(低电流或转折区)
  • 结温范围:-50℃ ~ +150℃
    说明:以上参数为器件典型/额定值摘要,具体测试条件(如测试电流 Iz、环境温度、测量方法等)请以 PANJIT 正式数据手册为准,以保证设计一致性。

四、封装与机械特性

  • 封装形式:SOD-123(表面贴装)
  • 小型化,可兼容常见贴片线与回流焊工艺。
  • 引脚极性与封装标记请参照包装说明与产品外形图;实际装配时注意方向识别,防止极性错误导致电路异常。

五、典型应用

  • 7.5V 基准稳压:用作小电流基准电压源或精密电压比较参考。
  • 过压/浪涌保护:在小电流信号线上作为钳位元件,保护下游电路免受瞬态高压冲击。
  • 电源辅助稳压:与串联限流电阻配合,为小负载或前端模拟电路提供稳定电压。
  • 仪表与传感器接口:低漏电流特性适合高阻抗测量与传感器偏置场合。

示例电路(参照原理):
在作为并联稳压器使用时,通常在输入电源与负载间串联一个限流电阻 R,R 的选择满足在最小输入电压与最大负载电流条件下,稳压二极管保持在其工作电流范围内。计算公式:R = (Vin_min - Vz) / (Iz + IL),其中 Iz 为稳压二极管工作电流,IL 为负载电流。

六、使用建议与注意事项

  • 热设计:Pd = 500 mW 为额定耗散,实际应用中需考虑焊盘、PCB 散热与环境温度对结温的影响。高温环境下应适当降额使用或改善散热条件,避免长时间在额定耗散下工作导致可靠性下降。
  • 测试条件核对:Zzk、Zzt 等阻抗值与 Ir 值通常依赖于特定测试电流和电压点,设计时请参考完整数据手册以获取对应测试条件。
  • 焊接工艺:采用标准回流焊工艺,遵循 SMD 元件的温度升温曲线与冷却速率,避免过热导致封装应力或可靠性问题。
  • ESD 与静电:作为半导体器件,应避免强静电放电,贴片、存储和装配阶段采取防静电措施。
  • 储存与搬运:避免潮湿、强腐蚀性气体环境,长时间存放建议按厂家推荐的湿敏等级(MSL)规范管理。

七、采购与质量

PANJIT(强茂)为业界知名半导体器件供应商,产品批次稳定,适合量产与工程应用。选型与批量采购时,建议索取并确认最新数据手册、可靠性试验报告及合格证书,以保证器件参数与供应一致性。

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
