BAT42W 肖特基二极管（YANGJIE 扬杰）产品概述
一、产品简介
BAT42W 是一款小功率肖特基整流二极管，扬杰（YANGJIE）品牌，采用 SOD-123 表面贴装封装，适用于对正向压降和反向漏电有较高要求的小信号与低功耗电源场景。器件针对 200mA 级别工作电流进行了参数优化，在便携设备和保护电路中具有良好的表现。
二、主要电气参数
- 正向压降（Vf）：1V @ 0.2A
- 直流反向耐压（Vr）：30V
- 额定整流电流：200mA（连续）
- 反向漏电流（Ir）：500nA @ 25V
- 非重复峰值冲击电流（Ifsm）：4A（单次浪涌）
以上参数表明器件在中等电流下保持较低的正向压降和极小的反向漏电，且能承受短时浪涌冲击。
三、产品特性与优势
- 低正向压降：相比普通硅二极管，肖特基结构在低压差条件下能减少功率损耗，有利于提高效率和延长电池续航。
- 低反向漏电：500nA @25V 的漏电水平适合对静态功耗敏感的便携式与电池供电设备。
- 紧凑封装：SOD-123 体积小，利于高密度 PCB 布局与自动化贴装。
- 抗浪涌能力：4A 的单次峰值浪涌能力可应对开机、负载突变等瞬态冲击。
四、典型应用场景
- 反向极性保护（电源输入保护）
- 低压差整流、旁路与耦合电路
- 便携设备与电池管理电路（耳机、手持仪器等）
- 开关电源次级整流、小信号保护与钳位电路
五、使用与选型建议
- 若工作电流长期接近 200mA，建议评估PCB散热条件并适当留有余量，避免长期高温运行。
- 对于更低的正向压降需求或更高电流应用，可考虑更高规格的肖特基器件；若对反向耐压要求高于 30V，应选择更高 Vr 的型号。
- 采用标准 SMD 贴装流程，建议在回流焊工艺和温度曲线上与制造流程验证后量产。
六、封装与可靠性
SOD-123 表面贴装封装便于自动化生产，机械强度和焊接可靠性良好。器件适合批量贴装与回流焊；在实际设计中注意焊盘尺寸与热路径设计，以保证散热与长期可靠性。
总结：YANGJIE 的 BAT42W 以其低漏电、适度的正向压降和小巧封装，适合各类低功耗、小型化电子产品中的保护与整流应用。选择时结合工作电流、散热和耐压要求即可获得稳定性能。

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.
