BZX584C39 Y14 — 39V 稳压二极管（SOD-523）
一、产品概述
BZX584C39（标记 Y14）是江苏长电/长晶（CJ）生产的小型表面贴装稳压二极管，标称稳压值为 39V，稳压范围 37V～41V，适用于低功耗、低电流的稳压与保护应用。封装为 SOD-523，体积小、适合高密度贴装电路板。
二、重要参数
- 稳压值（标称）：39V
- 稳压范围：37V ～ 41V
- 反向电流 Ir：≤ 100 nA（在额定反向电压附近）
- 耗散功率 Pd：150 mW（结温与PCB散热条件决定实用限值）
- 阻抗 Zzt：130 Ω（在测量电流 Izt 条件下）
- 阻抗 Zzk：350 Ω（在测量电流 Izk 条件下）
- 工作结温范围：-55 ℃ ～ +150 ℃
- 封装：SOD-523（表面贴装）
- 品牌：CJ（江苏长电/长晶）
三、性能与特性
- 小封装、低剖面，适合空间受限的便携设备与高密度 PCB。
- 极低的反向漏电（Ir），适合对静态功耗敏感的电路。
- 中等静态阻抗（Zzt/Zzk）表明在小电流变化时输出电压有一定的动态变化，适合作为参考或低电流稳压元件，但不建议用于要求高精度的大电流稳压场合。
- 宽工作温度范围，可靠性良好，适合多环境应用。
四、应用建议
- 小电流基准/稳压：例如传感器供电、偏置电路、参考电压源。
- 过压/浪涌保护：在受限空间内对敏感器件进行简单的夹位保护。
- 电平移位与信号链偏置：在模拟前端或接口电路中提供稳定的参考点。
五、选型与使用注意事项
- 功耗限流：理论最大稳态电流 Imax ≈ Pd / Vz ≈ 150 mW / 39 V ≈ 3.8 mA。由于 SOD-523 封装和 PCB 散热影响，实际连续工作电流应进一步保守选择（建议 ≤ 2–3 mA），并采用合适的限流电阻和热管理。
- 动态阻抗影响：较高的 Zzt/Zzk 表明在负载或电流变化时电压会跟随变化，若需更精确的参考，应考虑使用低阻抗的参考源或配合温度补偿。
- 焊接与可靠性：作为表面贴装器件，应按 PCB 工艺合理进行回流焊接，避免长时间高温暴露影响性能。
- 温升监控：在高温环境或并行器件密集区域使用时须留意结温，避免超过 +150 ℃ 极限。
六、典型电路示意（文字描述）
常见用法为将 BZX584C39 作为并联稳压元件：输入电源经限流电阻 R 到二极管，二极管反向工作以维持近似 39V；输出端并联负载。设计时按最坏工况计算限流电阻以保证在最大输入电压下二极管和电阻的功耗均在安全范围内。
如需更精准的参数表、曲线图或样品评估数据，请告知用途与工作条件，我可帮您核算稳态电流、限流电阻与热裕度建议。

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.
