BAT43WS 产品概述(GOODWORK 固得沃克)

一、产品简介

BAT43WS 是一款基于肖特基势垒结构的低压降小信号二极管,由 GOODWORK(固得沃克)生产,封装为 SOD-323、小巧独立式元件。该器件具有极低的正向压降和良好的开关速度,适用于便携设备、功耗敏感电路及高频检测/整流场合。额定反向耐压为 30V,最大整流电流 200mA,适合小电流整流与保护用途。

二、主要特点

  • 低正向压降:Vf = 260mV @ IF = 2mA,显著降低功耗并改善小电流下的导通效率。
  • 低反向漏流:Ir = 500nA @ VR = 25V(室温),在高阻抗电路中保持较低泄漏。
  • 适中抗浪涌能力:单次非重复峰值浪涌电流 Ifsm = 800mA,可承受短时突发能量。
  • 宽工作温度:结温范围 -55°C 至 +125°C,满足工业级应用的环境要求。
  • 小型表面贴装:SOD-323 封装,便于高密度 PCB 布局与自动贴装焊接。

三、电气参数概要

  • 正向压降(Vf):约 260mV(IF = 2mA)
  • 直流反向耐压(Vr):30V(最大)
  • 最大整流电流:200mA(连续)
  • 反向电流(Ir):500nA(25V,室温)
  • 峰值非重复浪涌电流(Ifsm):800mA
  • 工作结温:-55°C ~ +125°C

四、封装与机械特性

SOD-323 小型封装适合空间受限的电路板设计。该封装体积小、焊接良好,但热阻相对较高,需在设计中注意散热路径和铜箔面积的合理布局,以避免长期大电流下的结温升高。

五、典型应用场景

  • 电源轨反向/极性保护(小电流场合)
  • 信号整流与检测(射频包络检波、低电平信号检波)
  • 电平移位与逻辑隔离(低压、低电流)
  • 输入防护二极管(防止瞬态反向电压)
  • 便携式、低功耗电子产品中的面向效率优化的整流元件

六、设计与使用注意事项

  • 在设计中应保证正向电流不超过 200mA 的连续额定值,且长期工作时应考虑结温与环境温度对可靠性的影响。
  • 反向电流随温度上升显著增加,若电路对泄漏敏感,应在高温条件下做额外验证或选择更低漏电型号。
  • SOD-323 封装热阻较大,若在近额定电流下长期使用,建议增加 PCB 铜箔散热或调整布局以降低结温。
  • 单次浪涌能力为 800mA,但不建议将其作为长期过流保护依赖,需通过限流或熔断器保护关键负载。
  • 焊接过程中参考厂商建议的回流曲线,避免长时间过高温度以保护封装与内部焊点。

七、可靠性与环境适应

BAT43WS 的工作结温范围宽,适用于工业环境。长期可靠性受工作温度、反复热循环和过流事件影响,建议在产品验证阶段进行加速寿命测试(温度循环、湿热、振动)以确认在目标应用中的稳定性。

八、选型建议与替代

若目标应用要求更高电流或更高反向耐压,可考虑功率更大的肖特基或整流二极管;若需要更低漏电或更低 Vf,应在参数表中比较温度特性与试样数据。GOODWORK(固得沃克)提供一致性良好的批次供应,适合量产应用。

总结:BAT43WS 是一款小型、低压降、适合低功耗与高频信号场合的肖特基二极管,凭借 30V 的耐压与 200mA 的连续电流能力,在便携设备、电平整流与保护电路中具有良好性价比。选用时应综合考量工作电流、热管理与漏电在高温下的变化。

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.
