BZX84C18_R1_00001 产品概述
一 产品简介
BZX84C18_R1_00001 是 PANJIT（强茂）提供的一款独立式稳压二极管，标称稳压值 18V，适用于对电压基准和过压保护有中等精度要求的小信号应用。器件采用 SOT-23 小封装，体积小，便于表面贴装和批量生产，适配空间受限的消费电子与工业控制电路。
二 主要参数
- 稳压值（标称）：18V
- 稳压值允许范围：17.1V ~ 18.9V
- 反向电流 Ir：≤100 nA（典型测试条件见数据表，如 12.6V）
- 耗散功率 Pd：410 mW（在指定散热条件下）
- 动态阻抗 Zzt：45 Ω（在标定测试电流下测得）
- 拐点阻抗 Zzk：225 Ω（低电流区态特性）
- 工作结温范围：-55 ℃ ~ +150 ℃
- 封装：SOT-23（3 引脚，独立二极管）
以上参数为典型或最大额定值，具体应用时请参考完整规格书和测试条件。
三 特性与优点
- 低漏电：反向电流极小，有利于在高阻抗电路中保持稳压精度并降低静态能耗。
- 小封装高可靠：SOT-23 封装兼顾体积与机械强度，适合自动贴片工艺。
- 宽温度范围：-55 ℃ 到 +150 ℃ 的工作结温，满足工业级温度要求。
- 良好的动态响应：在中等电流范围内动态阻抗较低，有利于维持稳压稳定性。
四 典型应用
- 电压参考与校准电路。
- 电源过压保护与钳位电路。
- 仪表放大器和传感器前端的基准稳压。
- 小功率稳压模块与分立式稳压方案。
- 消费类电子、通信终端、工业控制板等领域。
五 使用建议与注意事项
- 保持稳压器件两端的最小工作电流，以确保稳压值落在标称范围内；在超低电流下，稳压值可能偏离额定值。
- 由于 Pd 仅为 410 mW，设计时需评估工作电流和电压降所产生的功耗，必要时采用散热路径或并联方案降低结温。
- 在高温或高功耗工况下，应参考器件热阻和电路板热特性，避免超温导致参数漂移或失效。
- 焊接与回流工艺遵循 PANJIT 的封装工艺指南，避免过热影响器件可靠性。
六 封装与质量保证
SOT-23 封装适用于自动化贴装，生产过程和出货前通常经过电气测试和外观检查。PANJIT 提供标准化质量控制与技术支持，可根据需求索取完整规格书和可靠性测试报告。
七 采购与资料
型号：BZX84C18_R1_00001，品牌：PANJIT（强茂），封装：SOT-23。采购前请确认所需的最小订购量、包装形式及所用生产批次的规格书修订版。有关更详细的电气特性曲线、测试条件及典型应用电路，请参考官方数据手册或联系技术支持。

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.
