ZMM55-C43_R1_10001 产品概述

一、产品简介

ZMM55-C43_R1_10001 是 PANJIT(强茂)出品的一款高稳定性稳压二极管,采用 MiniMELF 小型管状封装,专为需要精确稳压与高温工作能力的电路设计而生。器件在反向击穿工作区提供约 43V 的标称稳压,用于稳压、过压保护和参考电压源等场合。

二、主要性能参数

  • 标称稳压(Vz):43 V
  • 稳压范围:40 V ~ 46 V
  • 反向电流(Ir):100 nA @ VR = 1 V
  • 耗散功率(Pd):500 mW(注意需按热阻与实际 PCB 散热条件降额使用)
  • 动态阻抗(Zzt):90 Ω(测试点对应的稳压动态阻抗)
  • 低电流阻抗(Zzk):600 Ω(在低测试电流/膝点附近的阻抗)
  • 工作结温范围(Tj):-65 ℃ ~ +175 ℃
  • 封装:MiniMELF(管状/小体积,便于自动贴装)

三、关键特性与优势

  • 稳压精度高:标称 43V,并给出 40–46V 的允许范围,便于在系统设计时预估稳压偏差。
  • 低漏电流:Ir 在 1V 条件下仅 100 nA,适合对静态漏电要求高的应用。
  • 宽温度范围:-65 ℃ 至 +175 ℃ 的结温工作范围,适应工业级及高温环境。
  • 体积小、可靠性好:MiniMELF 封装在占板空间极小的同时具备良好的机械和热稳定性。
  • 动态阻抗特性适中:Zzt 与 Zzk 值表明器件在不同工作点下的电压变化敏感度,有利于分析电路噪声与负载变化影响。

四、封装与可靠性

MiniMELF 小型管状封装便于自动化贴装与回流焊工艺,且热容较小,有利于短时浪涌能量的吸收。但由于封装尺寸与散热限制,器件的额定耗散功率(500 mW)需基于实际 PCB 散热条件进行降额管理。推荐在高功耗场合采用散热良好的走线或增加铜箔面积以降低结温。

五、典型应用场景

  • 中高压参考源与基准稳压电路
  • 电源保护与过压抑制电路
  • 工业控制、通讯设备中的电压钳位
  • 高温或宽温度漂移要求的仪表与传感器接口

六、选型与使用建议

  • 热管理:工作电压和流过稳压二极管的电流决定耗散功率,若长期工作接近额定 Pd,需增加散热措施或在设计时按安全裕度降额。
  • 工作点选择:参考器件给出的 Zzt(90 Ω)和 Zzk(600 Ω),在不同电流下稳压点的电压漂移可以据此估算,必要时使用外部电阻或稳压电路予以稳定。
  • 漏电限制:若系统对静态漏电敏感,应注意器件在不同温度下漏电随温度升高可能增加,设计上留有裕度。
  • 封装处理:MiniMELF 封装在自动贴装与焊接时应遵守封装承受温度限制与回流曲线,避免机械应力导致玻璃/管状封装破损。
  • 极性识别:正确识别阴极标记并按电路图接入,反向击穿时器件起稳压作用。

七、结论

ZMM55-C43_R1_10001 是一款面向工业与高温环境的 43V 级稳压二极管,具有低漏电、高温耐受和小体积封装的优势。适用于需要中高电压稳压或过压保护的电路设计。选用时关注实际工作电流与 PCB 散热条件,按器件热额定进行合理降额与布线,以保证长期可靠性。若需更详细的电气特性曲线与封装尺寸,请参照 PANJIT 官方资料或向供应商索取完整数据手册。

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.
