ZMM20V 产品概述
一、产品简介
ZMM20V 是华轩阳电子（HXY MOSFET）推出的一款独立式稳压二极管（齐纳二极管），标称稳压值为 20V，适用于小功率稳压、浪涌钳位及参考电压源等场合。该器件采用 LL-34 小封装，体积小、易于安装，适合空间受限的消费电子和工业控制电路。
二、主要参数
- 稳压（标称）：20V
- 稳压范围：18.8V ～ 21.2V
- 反向漏电流 Ir：100nA（@ 1V）
- 最大耗散功率 Pd：500mW
- 动态阻抗 Zzt：55Ω
- 动态阻抗 Zzk：220Ω
- 配置形态：独立式（单个二极管）
- 封装：LL-34
- 品牌：HXY MOSFET（华轩阳电子）
三、产品特性
- 小封装、高可靠：LL-34 封装便于表面贴装或通孔安装，适配自动化生产。
- 稳定的稳压性能：在其规定的测试点下可保持接近 20V 的稳压输出，稳压值公差范围 18.8V～21.2V。
- 低漏电流：反向漏电流仅 100nA（@1V），适合对漏电敏感的电路设计。
- 快速响应：作为齐纳管，能在过压瞬变时提供限压保护。
- 低功耗应用优选：500mW 耗散能力适用于小功率参考与钳位场景。
四、典型应用
- 小型电源的稳压参考源与电压基准
- 输入浪涌或瞬变过压保护（钳位器）
- 模拟电路偏置与温度补偿网络
- 工业控制、通信设备及便携式电子产品中的低功耗稳压单元
五、封装与热管理
LL-34 封装散热能力有限，器件的最大耗散功率 Pd 为 500mW。在实际应用中建议考虑：
- 在较高环境温度或长期功率消耗场合对耗散进行退让设计；
- 通过合理的 PCB 铜箔面积或散热垫提升热扩散；
- 避免在接近额定功耗下长期工作以延长寿命。
六、选型与使用注意事项
- 根据电路工作点选择合适的稳流条件，避免过高的稳流导致过热；
- 留意稳压范围（18.8V～21.2V）是否满足系统容差要求；
- 在对噪声和阻抗敏感的场合，考虑 Zzt（55Ω）与 Zzk（220Ω）对输出纹波的影响；
- 严格遵守器件的最大反向电压和功率限制，避免击穿损坏。
ZMM20V 以其稳定的电压特性、低漏电和小型封装，在需小功率稳压与过压保护的场景中具有很好的实用性，适合广大电子设计工程师在多种应用中选用。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
