SHIKUES BAT43W(SOD-123)肖特基二极管产品概述

一、产品简介

SHIKUES(时科)BAT43W 为独立式小信号肖特基二极管,采用 SOD-123 封装。器件以低正向压降和快速恢复特性为主要优势,适合用于低压快速整流、反向保护与电平移位等场景。工作结温范围宽(-55℃~+125℃),满足多种工业与消费电子环境要求。

二、主要电气参数

  • 直流整流电流(Io):200 mA
  • 直流反向耐压(Vr):30 V
  • 正向压降(Vf):0.45 V @ 15 mA
  • 非重复峰值浪涌电流(Ifsm):4 A
  • 反向电流(Ir):500 nA @ 25 V
    这些参数表明该器件在中低电流、低压场合能提供较低的压降与较小的漏电,适合节能与低噪声设计。

三、热特性与可靠性要点

SOD-123 小封装热阻相对较大,设计时应考虑合理的铜箔散热与过载保护。器件允许的结温上限为 +125℃,建议在高温或长期重载工况下对整流电流进行降额使用以提高可靠性。

四、典型应用场景

  • 电源输入反向极性保护与低压差整流
  • 逻辑电平移位与门控保护
  • 探测、检波电路与小信号整流
  • 便携设备和通信设备的浪涌钳位

五、封装与工艺建议

SOD-123 封装适用于常见表面贴装回流焊流程,便于自动化贴装。建议在 PCB 布局时为器件预留足够焊盘面积及热散路径,并在靠近热源或高电流走线处加宽铜箔以降低结温。

六、选型与替代建议

若工作电流或耐压要求高于本器件规格,建议选用更大封装或更高 Vr/Io 的肖特基型号;若需要更低正向压降可选用专用低 Vf 系列。设计时应综合考虑正向压降、反向漏电与工作温度对系统功耗与可靠性的影响。

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
