MM1Z13BW 是 JSMSEMI(杰盛微)出品的一款独立式稳压二极管(Zener diode),标称稳压值为 13V,适用于中低功率的电压基准和过压保护场合。器件采用 SOD-123W 小型贴片封装,体积紧凑,适合密集布局的表面贴装电路。该型号在反向工作时具有很低的漏电流和较低的动态阻抗,能够在多种消费电子、工业控制与仪表等应用中提供稳定可靠的基准电压或稳压保护。
使用稳压二极管通常需与串联电阻配合,以控制流经器件的电流并限制耗散功率。常用计算公式:
示例(设计裕量):若 Vin = 24 V,期望稳压 Iz ≈ 10 mA,则
注意:当负载电流变化时,应保证在任何工况下二极管既不会过载,也能保持足够的稳压电流 Iz 来维持稳压特性。对于精度敏感的应用,应考虑动态阻抗带来的电压漂移并加以修正或选用更低阻抗的参考器件。
结语:MM1Z13BW(JSMSEMI)以其 13V 稳压值、低漏电流与小型封装,适合用于多种中低功耗的稳压与保护场合。正确的电路设计与热管理可充分发挥其性能并确保长期可靠运行。

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.
