BZX584B20V 产品概述
一、产品简介
BZX584B20V 是扬杰（YANGJIE）推出的独立式稳压二极管，标称稳压值为20V（工作范围19.6V～20.4V），采用 SOD-523 小型贴片封装。该器件针对空间受限、对电压基准要求稳定的低功耗电路设计，提供简单可靠的电压稳压/基准解决方案。
二、主要参数
- 稳压值（标称）：20V（范围 19.6V～20.4V）
- 反向电流 Ir：45 nA @ 14V
- 阻抗 Zzk：212 Ω
- 阻抗 Zzt：55 Ω
- 耗散功率 Pd：200 mW
- 工作结温范围：-55 ℃ ～ +150 ℃
- 封装：SOD-523（独立式/贴片）
三、主要特性与优势
- 电压稳定：20V 标称且公差范围窄（19.6V～20.4V），适用于对电压精度有一定要求的场合。
- 低漏电流：在14V 条件下反向电流仅45 nA，有利于延长电池供电设备的待机寿命。
- 小型化封装：SOD-523 占板面积小，适合高密度 SMT 布局及便携设备。
- 适用于低至中等功率场景：200 mW 的耗散功率要求在设计时注意热耗散与环境温度。
四、典型应用
- 参考电压/基准源（小电流场合）
- 过压保护与电压钳位
- 仪表与传感器前端偏置
- 电池供电与便携式设备的低功耗稳压单元
五、使用与设计建议
- 作为稳压/基准器件使用时，通常配合限流电阻成分压/分流电路，以控制二极管的工作电流并避免过热。
- 由于 Pd 为200 mW，应留意 PCB 布局与铜箔散热，必要时采用较大焊盘或热扩散设计以降低结温。
- 工作环境温度及结温不可超出-55 ℃～+150 ℃，高温下应考虑降额使用以保证长期可靠性。
- 小封装在回流焊制程中易受热影响，请遵循元器件及工艺规范进行焊接和回流。
六、封装与可靠性说明
SOD-523 封装提供良好的小型化解决方案，适合自动化贴装与批量生产。器件的低漏电和稳定阻抗特性有利于长期稳定工作，但在高温、高功耗工况下需加强热管理以保证寿命与性能稳定。
总结：BZX584B20V 以其20V 稳压值、低漏电和小尺寸封装，适合用于对体积和功耗敏感的稳压、基准与保护电路。设计时应注意功耗与热散布以发挥最佳性能。

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.
