ZMM5239B_R1_10001 产品概述

一、产品简介

ZMM5239B_R1_10001 为 PANJIT(强茂)生产的一款 9.1V 微功率稳压二极管,采用 MIN I-MELF 封装。器件为单个独立式稳压二极管,标称稳压值 9.1V,额定耗散功率 500mW,适合小型化、对精度与稳定性有一定要求的低功耗电路作电压基准或过压钳位使用。

二、主要特性

  • 标称稳压值:9.1V(标称)
  • 稳压值范围:8.65V ~ 9.56V(出厂范围)
  • 反向电流 Ir:3 μA @ 7V(低漏流,适合微安级偏流应用)
  • 最大耗散功率 Pd:500 mW(需注意热管理)
  • 稳压动态阻抗 Zzt:10 Ω(测试点动态阻抗)
  • 膝部阻抗 Zzk:600 Ω(低电流区特性)
  • 工作结温范围:-65 ℃ ~ +175 ℃
  • 封装:MINI-MELF(圆柱体小封装,便于自动贴装或波峰/回流焊)

三、典型电气参数与含义

ZMM5239B 在规定测试条件下呈现 9.1V 的稳压电压,Zzt(10 Ω)表示在测试电流下的交流阻抗,决定输出纹波抑制能力;Zzk(600 Ω)反映在膝部小电流区的电阻特性,影响低偏流时的稳压陡峭度。Ir=3 μA 表明在低反向电压下的漏电流较小,适合用作参考源或小信号钳位。

四、典型应用场景

  • 小功率线性稳压与基准电压源(便携设备、传感器前端)
  • 信号线和电路的过压保护、浪涌钳位
  • 模拟电路参考、比较器基准电压
  • 试验台或工程样机中作为简单稳压元件使用

五、可靠性与热管理

额定耗散功率为 500 mW,在实际应用中须结合封装散热和环境温度进行功耗分配与降额设计。器件允许的工作结温范围宽(-65 ℃ ~ +175 ℃),但长期工作在高结温下会影响寿命与稳压精度。建议参考厂方数据手册中的热阻和降额曲线,在印制板布局中增加铜厚或热沉路径,避免局部过热。

六、使用建议与封装注意事项

  • 作为基准时,应搭配合适的偏流电阻,使二极管工作在稳定的测试电流或推荐电流区间,防止自热导致电压漂移。
  • MIN I-MELF 封装便于自动化装配,但对焊接工艺敏感,建议遵循 PANJIT 的回流/波峰焊工艺规范,避免长时间高温或机械夹持导致封装损伤。
  • 储存与搬运时避免潮湿、强振动与静电冲击。验收时按稳压值范围与漏电流指标抽检,保证批次一致性。

如需完整电气特性曲线、测试条件与焊接参数,请参考 PANJIT 官方数据手册或向供应商索取相关技术文件,以便在设计中正确评估热特性与长时间稳定性。

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
