WILLSEMI WSB5507W-2/TR 产品概述

WSB5507W-2/TR 是韦尔(WILLSEMI)推出的一款小尺寸肖特基势垒二极管,采用 SOD-323 表面贴装封装,面向便携电源、整流与保护电路的高密度应用场景。该器件以低正向压降和较好的浪涌承受能力为特点,在 500mA 额定电流下表现出优良的导通效率与热稳定性。

一、核心参数一览

  • 型号:WSB5507W-2/TR(WILLSEMI)
  • 正向压降:Vf = 0.55 V @ IF = 500 mA
  • 额定整流电流:IF = 500 mA(持续)
  • 反向耐压:VR = 40 V
  • 反向电流:IR = 100 μA @ VR = 40 V
  • 非重复峰值浪涌电流:IFSM = 7 A(单周期浪涌)
  • 封装:SOD-323,适合高密度贴片组装

二、主要特性与优势

  • 低正向压降:在中等电流下(500 mA)Vf 仅约 0.55 V,有助于降低整流损耗和系统发热,提升效率。
  • 低反向漏电:40 V 条件下 IR 控制在 100 μA,适合中低功耗系统与充电保护场景。
  • 良好浪涌能力:7 A 的峰值浪涌能力能承受瞬态冲击,增强系统抗干扰和启动稳定性。
  • 小型封装:SOD-323 占板面积小,适合空间受限的移动设备和便携模块。

三、典型应用场景

  • USB 电源与便携充电器的整流与反向保护
  • DC-DC 升降压转换器的输出整流
  • 电池管理(BMS)与电源路径保护
  • 功率开关旁路与保护二极管
  • 工业与消费电子中的通用整流与钳位

四、布板与热管理建议

  • SOD-323 封装热阻相对较高,建议在 PCB 上为二极管引脚预留散热铜箔,尽量增大焊盘面积并与地/电源平面热盲孔相连以提高热扩散。
  • 在靠近热源或高电流回路处布局时,保证周边器件有足够间距以利散热。
  • 若工作电流长期接近额定值,应考虑电流降额(derating),或采用并联/更大封装以降低结温。

五、可靠性与封装信息

  • SOD-323 表面贴装封装,适配常规回流焊流程,满足自动化贴装和回流温度规范。
  • 出厂通常以带卷(TR)形式供应,便于 SMT 生产线直接使用。
  • 对于严格环境或高温场合,建议参考完整数据手册中的最大结温、热阻与寿命测试数据进行设计验证。

WSB5507W-2/TR 结合低 Vf、合适的 VR 与良好的浪涌能力,是对体积与效率有要求的电子系统中性价比很高的肖特基整流/保护选择。若需更详细的特性曲线、封装尺寸或回流焊曲线,请参考厂商详细数据手册或向供应商索取样片进行评估测试。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
