MM1Z18W是晶导微电子推出的独立式稳压二极管,主打18V标称稳压值,采用小型化SOD-123W表面贴装封装,专为对尺寸、功耗及环境适应性要求较高的电子电路设计。该器件通过精准的稳压参数与宽温特性,可稳定实现18V电压参考或钳位功能,适配便携设备、工业控制、通信等多领域应用场景。
标称稳压值18V,实际工作范围为16.8V~19.1V,既满足多数电路对稳压精度的基本需求,又预留一定裕量适配负载波动或温度变化,避免因参数偏差导致电路异常。
反向偏置电压13V时,漏电流仅100nA(纳安级),远低于常规稳压管的漏电流水平。低漏电流可有效降低电路静态功耗,尤其适合电池供电的便携设备(如智能手表、蓝牙耳机),延长电池续航时间。
最大允许耗散功率500mW,结合18V稳压值可推算出最大工作电流约27.8mA(公式:(I_{max} = P_d / V_z)),能覆盖中小功率电路的稳压需求(如传感器信号调理、电源参考)。
典型动态阻抗45Ω,该参数反映稳压管对负载电流变化的响应能力——阻抗越低,负载电流波动时输出电压的变化越小,稳压性能更稳定。例如,当负载电流变化1mA时,输出电压波动仅约45mV,满足多数电路的稳压精度要求。
结温范围覆盖-55℃~+150℃,符合工业级器件的宽温要求,可在极端环境(如户外设备、高温车间、低温存储)中长期稳定工作,无需额外的温度补偿电路。
MM1Z18W采用SOD-123W表面贴装封装,具有三大核心优势:
晶导微电子作为国内半导体器件领域的专业厂商,MM1Z18W严格遵循国际电工委员会(IEC)及国内电子行业标准(GB)生产,参数一致性好,批量供货稳定。器件出厂前经过全参数测试,确保每批次产品符合标称规格,可满足客户对可靠性的要求。
该器件凭借精准稳压、低功耗、宽温特性及小型化封装,成为中小功率电路稳压/参考的高性价比选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
