BZX584C9V1 为 CJ(江苏长电/长晶)旗下的一款独立式稳压二极管(稳压管),标称稳压值为 9.1V,实际稳压范围为 8.5V ~ 9.6V。该器件采用 SOD-523 小型贴片封装,适用于对体积和成本敏感、需要稳压、基准或过压钳位的低功耗电路。器件工作结温范围宽(-55℃ ~ +150℃),适合多种环境应用。
器件封装为 SOD-523,极其紧凑,适合高密度贴片电路板。SOD-523 的小封装限制了热散能力,因此在实际应用中需关注功耗与环境温度对结温的影响。理论上在理想散热条件下,最大稳态电流 Iz_max 可由 Pd/Vz 估算:Iz_max ≈ 150 mW / 9.1 V ≈ 16.5 mA;但实际设计应按数据手册的热阻和热降额曲线进行电流、功率的降额处理,避免长时间接近最大耗散功率。
总结:BZX584C9V1 是一款适合低功耗、小体积场合的 9.1V 稳压二极管,具有低泄漏、宽工作温度范围和小型 SOD-523 封装,适用于稳压、基准和钳位等应用场景。在选型和使用时需重视功耗热管理与工作电流的降额设计,按数据手册规范进行验证和可靠性评估。

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.
