BZX584C3V9 产品概述
一、产品简介
BZX584C3V9 为 CJ（江苏长电/长晶）出品的独立式稳压二极管（Zener diode），标称稳压值 3.9V，实际稳压值范围为 3.7V 至 4.1V。器件采用微型 SOD-523 表面贴装封装，适合空间受限、对功耗要求较低的电子产品中作为基准电压源或过压保护元件使用。
二、电气参数
- 标称稳压（Vz）：3.9V（范围 3.7V～4.1V）
- 反向电流（Ir）：3 μA @ 1.0V
- 耗散功率（Pd）：150 mW（环境与焊接工艺影响散热能力，请按实际温升评估）
- 阻抗：Zzt = 90 Ω；Zzk = 600 Ω（分别反映在规定测试点的动态与低电流区阻抗特性）
- 工作结温范围（Tj）：-55℃ ～ +150℃
三、主要特性
- 小型表贴封装（SOD-523），便于高密度贴装与自动化生产。
- 低功耗设计，Pd=150mW，适用于小电流稳压与参考源场合。
- 低反向漏电流（3 μA @ 1.0V），有利于待机或低功耗电路的电流预算。
- 较宽的工作温度范围，适用于工业温度等级的产品设计。
四、典型应用
- 低功耗电源参考与基准电压源。
- 输入端或信号线的小功率过压/钳位保护。
- 模拟电路中电平偏置、参考稳压单元。
- 移动设备、物联网终端、传感器节点等空间受限场合。
五、封装与热管理
SOD-523 为微小封装，热阻相对较高，器件的最大耗散功率受 PCB 散热条件限制。实际电路设计中应：控制稳压二极管上的功率损耗，留足焊盘铜箔面积以改善散热，避免在高环境温度或连续高电流条件下长期工作导致结温超过规格。
六、使用建议与注意事项
- 选择工作电流时考虑阻抗特性，低电流下稳压精度会下降（Zzk 较大）。
- 在并联使用时注意电流均分问题；若需更高功率请采用功率更大的封装或外部散热措施。
- 焊接工艺应符合 SMD 焊接规范，避免过热损伤器件。
- 设计时预留容差空间，参考器件稳压范围（3.7V～4.1V）以满足电路精度要求。
七、品牌与质量保证
CJ（江苏长电/长晶）为国内知名半导体制造商，产品覆盖广泛的二极管与分立器件系列。BZX584C3V9 在规格、出货一致性与可追溯性方面满足常规工业与消费电子应用的需要，如需批量采购建议与供应商确认器件的版本与检验报告。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
