TPWSB5557Z 产品概述

一、产品简介

TPWSB5557Z 是台舟电子(TECH PUBLIC)推出的一款小封装肖特基二极管,封装形式为 DFN0603-2。该器件面向低压、低功耗的整流与保护应用,具有低正向压降与较快恢复特性,适合移动设备、通信模块、USB 电源路径与一般开关电源的小电流整流场合。

二、主要电气参数

  • 型号:TPWSB5557Z(品牌:TECH PUBLIC / 台舟电子)
  • 二极管类型:肖特基(Schottky)
  • 正向压降:Vf = 0.53 V @ If = 100 mA
  • 连续整流电流:IF = 100 mA
  • 非重复峰值浪涌电流:Ifsm = 2 A(短时脉冲)
  • 直流反向耐压:Vr = 30 V
  • 反向电流:Ir = 700 μA @ Vr = 30 V
  • 封装:DFN0603-2(超小贴片封装)

三、特性与优势

  • 低正向压降:0.53 V 在 100 mA 条件下,可减少功率耗散和压降,适用于需要较低导通损耗的电源路径。
  • 小型化封装:DFN0603-2 占板面积极小,便于高密度 PCB 布局。
  • 耐浪涌能力:2 A 的非重复峰值浪涌能力能抵御启动或短时冲击电流。
  • 低压能力:30 V 的反向耐压适合常见 5 V/12 V 等低压系统。

注意:在 30 V 反向电压下反向漏电为 700 μA,相对某些肖特基来说偏高,需在对待机/漏电严格的系统中评估其对功耗的影响。

四、典型应用场景

  • USB、Type-C 电源路径整流与反向保护
  • 小电流整流和电源切换(OR-ing)
  • 便携设备和通信模块的低压保护电路
  • 二极管防反接、函数保护和电源去耦场合

五、封装与布局注意事项

  • DFN0603-2 为裸片式小封装,对 PCB 散热能力依赖较大,建议在器件下方设计适当的焊盘和热铺铜,提高散热能力。
  • 对于连续 100 mA 的应用,若 PCB 铜面有限,建议对整流电流做降额或增加散热面积;在典型小板上可考虑将工作电流控制在 50–80 mA 范围以提高可靠性(具体以厂方热阻与数据表为准)。
  • 建议使用标准无铅回流曲线进行贴片焊接,焊盘设计与焊膏量以厂方推荐图样为准,避免过量焊膏造成焊接缺陷。

六、选型与可靠性建议

  • 若系统对待机漏电非常敏感(μA 级以下),应谨慎使用本型号;可考虑低漏电肖特基或普通整流二极管作权衡。
  • 对于需要更高浪涌或更大连续电流的应用,选择更大封装或并联器件并进行热仿真。
  • 量产前建议做温升测量、反向漏电随温度变化测试以及实际电源路径的长期稳态验证。
  • 注意 ESD 与储存防潮规范,贴片器件应按标准湿敏等级处理。

七、结论

TPWSB5557Z 以其低正向压降与超小 DFN0603-2 封装,适合空间受限且对压降敏感的小电流整流与反向保护应用。设计时需兼顾其 30 V 下的漏电特性与小封装的热特性,推荐在选型与 PCB 布局阶段进行热与漏电评估,并参照厂方完整数据手册完成最终设计验证。若需更详细的热阻、回流曲线与推荐焊盘,请向台舟电子索取数据表或样品做现场测试。

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
