MMSZ5239B_R1_00001 — PANJIT(强茂)9.1V 独立式稳压二极管(SOD-123)

一、产品概述

MMSZ5239B_R1_00001 是 PANJIT(强茂)推出的一款独立式稳压二极管,标称稳压值 9.1V,适用于低功耗电压基准和过压保护场合。器件采用 SOD-123 小型封装,额定耗散功率 500mW,工作结温范围宽(-55℃ ~ +150℃),可靠性高,适合消费类电子、便携设备和工业控制等对尺寸与成本敏感的应用。

二、主要参数一览

  • 稳压值(标称):9.1V
  • 稳压值范围:8.65V ~ 9.56V
  • 反向电流 Ir:3 μA @ 6.5V(反向漏电在低电压下很小)
  • 最大耗散功率 Pd:500 mW(在良好热散条件下)
  • 动态阻抗 Zzt:10 Ω(典型测试条件下)
  • 低电流阻抗 Zzk:600 Ω(启动或极低电流条件下指标)
  • 工作结温:-55℃ ~ +150℃
  • 封装:SOD-123(表面贴装,体积小、焊接方便)
  • 封装/品牌:PANJIT(强茂)

三、性能特点与优势

  • 精确稳压:9.1V 标称电压并提供 8.65V~9.56V 的出厂范围,适合需中等精度基准的电路。
  • 低漏电流:在 6.5V 条件下反向电流仅 3 μA,有利于电池供电或待机功耗受限的系统。
  • 小封装高集成:SOD-123 封装在空间受限的 PCB 上易于布局,适合自动贴装生产。
  • 宽工作温度:-55℃ 到 +150℃,满足恶劣环境下的稳定性需求。
  • 良好瞬态响应:较低的交流动态阻抗(Zzt≈10Ω)保证在中等工作电流下具有较好的稳压和抗干扰能力。

四、典型应用场景

  • 小电流参考电压源与偏置网络
  • 电源轨的过压限制与保护
  • 信号链的局部稳压与基准
  • 电池供电便携设备的低功耗稳压单元
  • 工业和汽车电子中需要宽温域工作的低功耗稳压点

五、设计与使用建议

  • 最大允许电流可由 Pd / Vz 估算(理论最大约 500mW / 9.1V ≈ 55 mA),但受 SOD-123 热阻和 PCB 散热限制,实际使用应去乘以安全裕量;推荐在长期工作时保持远低于最大值(例如 ≤ 10–30 mA,视散热情况而定)。
  • 在作为稳压源使用时,需外接限流电阻以将工作电流限定在安全范围,同时考虑温度系数对稳压值的影响。
  • 对于低电流或待机场景,器件在低压区的高阻抗(Zzk≈600Ω)会使稳压点较敏感,应保证足够的偏流以进入稳态工作区。
  • SOD-123 封装焊接需注意回流曲线与良好 PCB 热量分布,以保证长期可靠性。

六、封装与采购信息

器件型号:MMSZ5239B_R1_00001
品牌:PANJIT(强茂)
封装:SOD-123,卷带包装适用于自动贴装生产。订购时请参考厂商完整器件编码与批次信息以确认稳压范围和测试条件。

七、结论

MMSZ5239B_R1_00001 是一款面向低功耗和体积受限应用的 9.1V 独立式稳压二极管,兼顾精度、低漏电与宽温域特性。正确的电流限制与热设计可以充分发挥其稳压与保护功能,是便携设备、工业控制与通用电子产品中常用的稳压选择。若需更详细的特性曲线或测试条件(如 IZT、测试电流下的 Zzt 定义、温度系数等),建议参考 PANJIT 官方规格书或联系供应商获取完整数据表。

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
