ZMM15 稳压二极管(500mW)产品概述

一、简介

ZMM15 是一款独立式(离散)稳压二极管,标称稳压值 15V,适用于低功率稳压、基准源和过压钳位场合。产品由 Slkor(萨科微)提供,封装为 LL-34(常见的轴向 DO‑35 类小型玻璃封装),最大耗散功率 500mW,适合空间受限且散热条件受限的电路板应用。

二、主要性能参数

  • 标称稳压值(Vz):15V
  • 稳压值范围:13.8V ~ 15.6V
  • 额定耗散功率(Pd):500mW
  • 反向电流(Ir):100nA(给定测试条件下,用户资料标注为 100nA@11V)
  • 阻抗(Zzk):110Ω(低电流或击穿起始区的静态阻抗)
  • 阻抗(Zzt):30Ω(在测试电流或额定工作点附近的小信号动态阻抗)
  • 封装:LL‑34(轴向玻璃封装/DO‑35 类)

三、特性与优势

  • 小型轴向封装,便于通过孔安装和手工焊接,适用于修理或小批量生产。
  • 低漏电流(100nA)在保持低静态损耗方面有优势,适合高阻抗参考或断电监测电路。
  • 500mW 的功耗级别适合为微功率电路提供稳定参考或作为局部钳位器件使用。
  • 在中等电流范围内(使用时注意由 Zzt、Zzk 影响的稳压精度)表现稳定。

四、典型应用

  • 低功耗电压基准与参考源
  • 过压保护与瞬态钳位
  • 电源辅助稳压(小电流分流型稳压器)
  • 仪表、传感器电路的基线偏置与保护
  • 通信及消费类电子的局部稳压

五、使用建议与电路设计注意事项

  • 功率限制计算:最大稳压电流 Iz_max ≈ Pd / Vz = 0.5W / 15V ≈ 33mA。实际设计中应远低于此值以延长寿命并保证稳定,常选工作电流 1–10mA 范围。
  • 串联限流电阻示例:若 Vin = 24V,目标 Zener 电流 Iz = 5mA,则 R = (Vin − Vz) / Iz = (24−15)V / 5mA = 1.8kΩ。此时 Zener 功率约 Pz = Vz × Iz = 75mW,安全在额定范围内。
  • 低电流下(接近 Zzk 条件)阻抗较大,稳压精度下降,应避免过低工作电流;需考虑 Zzt 在给定 Iz 下的小信号阻抗以估算输出纹波与动态响应。
  • 由于封装和功耗限制,须保证足够散热路径;在高环境温度下应按厂商温度系数和降额曲线降低允许功率(如资料未给出,建议保守考虑并做实际热测)。
  • 注意极性:LL‑34 轴向封装的一端为带环或标记端(阴极),焊接前确认极性。

六、封装与可靠性注意

  • LL‑34(玻璃轴向)对焊接热敏感,建议波峰或回流焊工艺控制在规范温度和时间内—手工焊接时避免长时间高温直接加热,典型建议焊接温度 ≤ 260°C,焊接时间短(数秒)。
  • 轴向引脚便于机械固定,但在震动或机械应力较大环境需加固管脚,避免玻璃体受力导致损伤。
  • 储存和使用时避免潮湿和机械冲击,长期高温环境下应考虑降额使用。

七、选型与替代原则

  • 若需更高功耗或更低动态阻抗,请选择更大功率的封装(如 1W 或以上)或低阻抗型号。
  • 对精度要求高的参考源,应配合温度系数更优和测试电流点明确的高性能稳压源替代。
  • 替代型号时确保稳压电压、功耗、漏电流和封装兼容,以免影响散热与机械装配。

结论:ZMM15(Slkor,LL‑34 封装)是用于微功率稳压和过压钳位的经济型选择,在合理控制电流与散热的前提下,可在多种消费电子与仪表应用中提供可靠的 15V 稳压参考。

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
