BZT52C2V0S 产品概述
一、概述
BZT52C2V0S 是 DOWO（东沃）出品的一款小功率稳压二极管，封装为 SOD-323，适用于空间受限的表面贴装电路。该型号属于未分类的标准低电压稳压二极管系列，主要用于提供近似 2V 的基准或纹波抑制。
二、主要特点
- 标称稳压值：2.0V
- 稳压范围：1.8V ~ 2.15V，适应制造偏差与工作温度变化
- 耗散功率：Pd = 200 mW，适合小电流低功耗场合
- 反向电流：Ir = 100 μA @ 1.0 V（典型泄漏规格）
- 阻抗：Zzt = 150 Ω、Zzk = 600 Ω（表征动态阻抗与弯曲区特性）
三、电气特性说明
稳压二极管在工作时近似恒压，Zzt（低电流测试阻抗）与 Zzk（弯曲区/高阻抗）表明在不同电流点上的动态响应：Zzt 较低时稳压能力更好，Zzk 较高则在低电流或接近击穿拐点时稳压性能下降。反向漏流在 1V 条件下可达 100 μA，设计偏置电阻与工作电流时应考虑该泄漏对电路性能的影响。
四、封装与热特性
SOD-323 封装体积小、适合自动贴片。最大耗散功率 200 mW 表明器件需在低功耗条件下使用，并且要注意散热和环境温度：在高温或近临界 Pd 工作时需降低通过电流以避免热失效。
五、典型应用
- 便携设备的低压参考源
- 信号线夹位或过压保护（轻微稳压/钳位）
- 小型传感器模块、低功耗模组的局部稳压
六、选型与使用注意
- 若电路需更精确的基准电压，应选择阻抗更低或热稳定性更好的参考源。
- 设计偏置电阻与供电，保证在稳压区有足够的工作电流，同时避免超过 Pd（200 mW）。
- 考虑反向漏流对高阻电路的影响，必要时并联保护或采用低漏型器件。
- SOD-323 封装焊接时注意回流曲线与湿热抵抗，避免封装热应力。
七、结论
BZT52C2V0S（DOWO，SOD-323）适合体积受限、对稳压精度要求不高的小功率场合。了解其稳压范围（1.8~2.15V）、耗散功率（200 mW）、阻抗及漏流特性，能帮助工程师在电源偏置与热管理上做出合理设计决策。

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.
