ZMM11V 稳压二极管产品概述

一、产品简介

ZMM11V 是永裕泰(YONGYUTAI)推出的独立式稳压二极管,额定稳压值为 11V,允许稳压范围 10.4V ~ 11.6V。器件采用 LL-34 小型轴向玻封封装,典型为 DO-35 类玻璃封装,适合通孔安装与手工或波峰回流焊接后布线的混合装配方式。额定耗散功率为 500mW,反向静态漏电流极小(Ir = 100nA @ 8.2V),适用于低功耗精密基准与保护电路。

二、电气性能要点

  • 标称稳压:11V(制造与测量条件下典型输出电压)
  • 稳压允许范围:10.4V ~ 11.6V(批次与工差范围)
  • 耗散功率 Pd:500mW(器件最大稳态功耗,使用时需留有余量)
  • 动态阻抗:Zzk = 70Ω(在起始拐点或低电流区的阻抗特性),Zzt = 20Ω(在额定测试电流附近的阻抗)
  • 反向电流 Ir:100nA(在 8.2V 时测得,表明低电流下泄漏很小)

说明:Zzk 与 Zzt 分别反映在不同工作点的阻抗特性,Zzt(较小)对应器件在额定测试电流时的交流等效阻抗,直接影响稳压精度与负载效应;Zzk(较大)反映低电流区的非线性行为。

三、设计与应用建议

  • 最大稳压电流估算:在器件允许的最大耗散功率 Pd 下,Iz_max ≈ Pd / Vz ≈ 0.5W / 11V ≈ 45mA。为延长寿命与保持稳定性,推荐工作电流显著低于这个值(通常建议 ≤ 1/2~2/3 的最大值,视散热条件而定)。
  • 稳压电路常见接法:作为并联型基准(分流稳压)、作为电压钳位或瞬态抑制器。配合上拉电阻 Rs 使用时,需按负载电流与所需稳压余量计算 Rs:Rs = (Vin - Vz) / (Iz + Iload)。
  • 负载与纹波:由于 Zzt ~20Ω(在测试电流时),在 Iz 变化或纹波较大时会产生明显的稳压漂移。对精密参考要求场合可并联低温漂电阻或选用低阻抗型号;对脉冲/瞬态抑制,需注意瞬态响应和功耗峰值。
  • 温度特性:稳压点随温度有一定漂移(典型为正温度系数或负系数,具体见厂家完整数据表)。高温时漏电流会上升,耗散能力受环境温度和散热条件限制,应做功率与热阻的余量设计。

四、主要应用场景

  • 低功耗电源基准:便携设备、传感器供给参考电压。
  • 过压/浪涌保护:限制敏感电路的最大电压峰值。
  • 信号线钳位:保护模拟输入或数字接口免受高压冲击。
  • 偏置/参考电压源:放大器与比较器的参考源或偏置网络。

五、封装与可靠性

  • 封装:LL-34(轴向玻璃封装),适合通孔安装,机械强度高、耐振动;玻封便于视觉焊接检查。
  • 焊接建议:避免长时间高温直焊,按行业推荐的峰值温度与时间曲线操作;手工焊接时注意热应力,间隔冷却以防玻璃管裂纹。
  • 存储与静电防护:尽管为玻封二极管,仍建议按常规电子元件规范储存并防静电放电(ESD)损伤。

六、选型与注意事项

  • 若需要更低噪声或更小稳压漂移,考虑低阻抗或更高功率等级的稳压二极管。
  • 在存在较大纹波或瞬态负载下,应检查峰值功耗是否超过 500mW 并适当增加限流或采用并联/串联方案分担功耗。
  • 使用前推荐查看厂家完整数据手册以确认测试电流、温度系数、极限参数和典型曲线,确保在给定工况下有足够余量。

总结:ZMM11V(YONGYUTAI,LL-34,500mW)适合用于中等精度、低功耗的稳压与保护场合。在电路设计中需关注耗散功率限制、动态阻抗对稳压精度的影响以及温度与纹波下的行为,通过合理选型与热设计可获得稳定可靠的性能。

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.
