BAT54WS 产品概述
一、产品简介
BAT54WS 是由 DOWO(东沃) 提供的小型肖特基整流二极管，采用 SOD-323 封装，设计用于空间受限且需低正向压降与较高整流能力的场合。本型号为单个独立式二极管，具有低 Vf 和良好的抗浪涌能力，适合便携式电源、信号钳位与反向保护等应用。
二、关键电气参数
- 正向压降 (Vf)：1.0 V @ 100 mA（典型应用工况下的参考值）
- 直流反向耐压 (Vr)：30 V
- 额定整流电流：300 mA（连续）
- 反向漏电流 (Ir)：2 μA @ 25 V
- 非重复峰值浪涌电流 (Ifsm)：600 mA
这些参数表明器件在小型化封装下兼顾了低损耗与一定的瞬态承受能力。
三、主要特性与优势
- 低正向压降：在中等电流工作时可显著降低功耗和发热，有利于延长电池供电系统的续航。
- 较高整流能力：300 mA 连续整流支持多类低功率负载驱动。
- 良好浪涌承受：600 mA 峰值浪涌可应对短时启动或突发脉冲电流。
- 小体积封装：SOD-323 有利于高密度 PCB 布局和空间受限产品设计。
四、典型应用场景
- 便携式设备的电源整流与选择路径
- 反向电压保护与电源防护电路
- 快速开关、钳位和低压降整流用途
- 信号线防护与低电压电平整合
五、封装与热管理
SOD-323 封装体积小、焊接方便，但热阻相对较高。设计中应注意：
- PCB 铜箔散热：适当增加焊盘和铜面积以改善热量扩散。
- 连续电流与环境温度匹配：在高环境温度或长期满载工况下，需要降低额定电流裕量以防止过热。
六、验收与注意事项
- 测试时按规定条件（如 100 mA 测量 Vf、25 V 测量 Ir）进行对比验收。
- 焊接建议采用符合 SOD-323 的回流温度曲线，避免超温导致性能退化。
- 高频开关或脉冲场合注意寄生电感与布局，必要时并联去耦或吸收元件以保护器件。
总结：BAT54WS（DOWO，SOD-323）在微小封装下提供了低正向压降与可靠的整流能力，适合对体积和效率有要求的低功耗与保护型电路。若需进一步的温升曲线、完整的 I-V 特性或封装尺寸图，可提供数据表以便精确设计。

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.
