MM1Z15W 是晶导微电子出品的一款小功率稳压(二极管)器件,标称稳压值为 15V,出厂稳压范围为 13.8V ~ 15.6V,标称精度 ±5%。器件支持宽工作结温 -55℃ 至 +150℃,适合空间受限和低功耗场合的基准与过压保护应用。封装为 SOD-123W,便于表面贴装组装与自动化生产。
基于 Pd 与 Vz 的关系,可估算最大稳压电流 Iz_max ≈ Pd / Vz = 0.5W / 15V ≈ 33mA。该值为在稳压区允许的最大电流上限,实际设计时应留有裕量以保证长期可靠性。
SOD-123W 为小型表贴封装,利于高密度布板和自动贴装。焊接建议遵循厂商的回流曲线,避免过高的峰值温度或长时间高温暴露以保护内部结构。焊盘设计应保证良好散热通道,必要时在焊盘下方或附近布置铜箔/过孔以利热量扩散。
结语:MM1Z15W 以其 15V 的标称稳压、低漏电和小型封装,适用于各类低功耗稳压与保护应用。选型时应重点关注功率限流、稳压电流设计及散热条件,以确保长期稳定可靠运行。

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.
