BAT46W 产品概述
一、产品简介
BAT46W 是扬杰（YANGJIE）推出的一款肖特基整流二极管，单个独立封装，采用 SOD-123 表面贴装形式。该器件设计用于小功率、高频切换与保护场合，结合较高的反向耐压与低反向漏电特性，适合对体积与成本敏感的消费类及工业电子应用。
二、主要电气参数
- 器件类型：肖特基二极管（单个独立式）
- 正向压降：Vf = 1.0 V @ If = 250 mA
- 直流反向耐压：Vr = 100 V
- 连续整流电流：Io = 150 mA
- 峰值非重复浪涌电流：Ifsm = 750 mA
- 反向电流：Ir = 2 μA @ Vr = 75 V
- 封装：SOD-123（表面贴装）
三、封装与热特性
SOD-123 为小型表贴封装，体积小、适合高密度 PCB 布局。由于封装面积有限，器件的热阻较大，长期允许的整流电流以 150 mA 为准，应在 PCB 设计中通过加宽铜箔、设置散热过孔或热面来改善散热性能，避免长期在接近极限负载下工作而导致过热失效。
四、典型应用场景
- 反向保护（电源输入防反接）
- 小信号整流与高频整流电路
- 便携式设备及低功率开关电源的输出整流
- 浮点保护与钳位电路（利用低漏电与较高耐压）
该器件适用于需要高耐压但单通道电流较小的场合。
五、使用建议与可靠性注意
- 在接近最大整流电流或连续工作温度上限时应做降额设计；推荐在 PCB 上增加散热铜箔。
- 注意反向耐压与瞬态冲击：Vr=100 V 为直流耐压上限，不应有超压或长时间反向应力。若存在瞬态尖峰，建议并联TVS或RC缓冲。
- 焊接工艺：SOD-123 支持常规回流焊，但应遵循厂家推荐温度曲线，避免因过热或重流造成封装损伤。
- 测试与存储：器件对潮湿敏感性较低，但建议按一般 SMD 器件管理，避免长期在高温高湿环境中存放。
六、选型建议
若设计中需要更低的正向压降或更高的连续电流，应考虑更大封装或额定更高的肖特基型号；若对反向漏电要求更严格，可比较不同型号的 Ir 指标。BAT46W 在 100 V 耐压与 μA 级漏电、并且 150 mA 连续电流场合具有成本与尺寸优势，是小功率整流与保护的实用选择。

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.
