BZX84C10（CJ 长晶）产品概述
一、产品简介
BZX84C10 是江苏长电（CJ/长晶）生产的一款小功率稳压二极管，标称稳压值 10V，采用 SOT-23 小封装设计，单只耗散功率额定为 300mW。器件适用于空间受限、低功耗的基准稳压与浪涌箝位场合，凭借小体积和良好的一致性，常用于便携设备与模拟前端的电压基准与保护电路。
二、主要电气参数
- 稳压值（标称）：10V
- 稳压值（范围）：9.4V ～ 10.6V
- 直流反向电流 Ir：200nA（@7V）
- 耗散功率 Pd：300mW
- 阻抗（Zzk）：150Ω
- 阻抗（Zzt）：20Ω
- 封装：SOT-23
三、主要特性与优势
- 小体积（SOT-23），便于表贴工艺与紧凑 PCB 布局。
- 低反向漏流（200nA@7V），适合对静态电流敏感的电路。
- 合理的动态阻抗（Zzt = 20Ω）在工作电流范围内能提供稳定的电压参考；较高的 Zzk 表示在击穿前的特征需注意。
- 额定耗散 300mW，满足多数低功耗稳压和钳位应用。
四、典型应用场景
- 精密参考电压源（与限流电阻组成简易稳压源）
- 信号链保护与过压钳位
- 电源轨去耦与基准校准
- 便携式与电池供电设备的低功耗稳压
五、选型与使用建议
- 确保在设计中限制流过稳压二极管的电流，使功耗不超过额定 Pd（考虑环境温度与 PCB 散热条件进行降额）。
- 对于要求更低噪声或更精确参考的场合，建议使用专用基准源；BZX84C10 适用于成本和空间受限且容忍一定精度误差的场合。
- 在电路中常与串联限流电阻配合使用，计算时应考虑稳压电流、功耗和电阻两端压降。
- 高温环境下注意热阻影响，尽量改善铜箔面积以提升散热能力。
六、封装与可靠性提示
SOT-23 封装便于自动化贴装，但散热能力有限。焊盘设计与 PCB 铜箔面积会显著影响器件的最大可用功耗与可靠性；焊接工艺应符合厂家推荐的温度规范，以保证长期稳定性。

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.
