ZMM55-C8V2_R1_10001 产品概述
一、产品简介
ZMM55-C8V2_R1_10001 是一款独立式稳压二极管（Zener），由 PANJIT（强茂）生产，封装为 LL-34。其标称稳压值为 8.2V，公差范围 7.7V ~ 8.7V，设计用于作为低功率电压基准、过压钳位和稳压保护等用途。器件为离散封装，便于通孔安装和手工焊接处理。
二、主要电气参数
- 稳压值（标称）：8.2 V（范围 7.7 V ~ 8.7 V）
- 反向漏电流 Ir：100 nA（规格给出，实际随温度与偏置电压变化）
- 耗散功率 Pd：500 mW（最大耗散，工作时需注意结温）
- 稳态阻抗 Zzt：7 Ω（在测试电流下，体现稳压纹波抑制能力）
- 动态阻抗 Zzk：50 Ω（在低电流或快速变化条件下的表现）
- 工作结温范围：-65 ℃ ~ +175 ℃
三、性能特点与优势
- 低漏电流：Ir 规格为 100 nA，适合高阻抗、微电流电路中的参考与偏置使用。
- 良好稳压特性：Zzt 仅 7 Ω，表明在额定测试电流附近具有较低的动态阻抗和较好的负载调节能力。
- 宽温度与长寿命：工作结温范围宽，适合在工业级与军工级温度环境下使用（需关注热管理）。
- 通用封装：LL-34 通孔封装便于装配和替换，适合维修及小批量手工装配。
四、热与电流管理
按最大耗散 Pd=500 mW，理论上最大稳压电流 Iz_max ≈ Pd / Vz ≈ 0.5 W / 8.2 V ≈ 61 mA。但实际使用时应考虑结到环境的热阻与安全余量，建议在无额外散热的情况下将工作电流限制在额定值的 30%~60% 范围内，或通过限流电阻和合适的散热措施降低结温以保证长期可靠性。
五、典型应用与选型建议
- 典型应用：基准电压源、过压/浪涌保护、电压钳位、偏置网络、便携式与仪表电路的电压参考。
- 选型建议：若要求更高精度或更低温漂，可选公差更小或温度系数更优型号；若需更高功率处理或更低阻抗，则考虑功率更高或低阻抗系列产品。
六、使用注意事项
- 留意反向漏电流随温度上升而增加，在微电流回路中应进行温度补偿或选用更低漏电流等级。
- 采用限流电阻以控制通过二极管的电流，防止超过器件在特定封装下的结温限制。
- 焊接时应避免过高的焊接温度和过长的作用时间，以免影响封装和参数稳定性。
总结：ZMM55-C8V2_R1_10001 以其 8.2V 标称、低漏电流及良好稳态阻抗，适合用于中低功率的基准与保护场合。正确的电流限制与热管理可确保其在长期工作中的稳定与可靠。

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.
