SK4001WA 产品概述 — SHIKUES(时科) 通用整流二极管(SOD-123FL)

一、产品简介

SK4001WA 是时科(SHIKUES)推出的一款通用独立式整流二极管,采用 SOD-123FL 小型封装,面向开关电源、整流、浪涌吸收与反向保护等通用场景。器件设计注重低正向压降与低反向泄漏,体积小、便于表面贴装,适合空间受限的消费电子与工业控制设备。

二、主要电气参数

  • 二极管配置:独立式
  • 正向压降(Vf):1.1V @ 1A
  • 直流反向耐压(Vr):50V
  • 最大整流电流:1A
  • 反向电流(Ir):5μA @ 50V

以上参数表明 SK4001WA 在 1A 工作电流下具有较低的正向压降,且在中低压(≤50V)电路中具有良好的反向耐压与极低的漏电流,适合直流整流与一般保护用途。

三、封装与机械特性

SK4001WA 采用 SOD-123FL 表面贴装封装,封装体积小、厚度适中,利于高密度 PCB 布局与自动化贴装。具体尺寸和焊盘建议请参照厂商封装图纸,以保证焊接质量与热散逸性能。

四、典型应用场景

  • 开关电源与适配器次级整流
  • 充电器与电源管理模块的整流与保护
  • 低压电机驱动与继电器驱动电路
  • 反向电流保护、浪涌吸收与电路钳位

五、设计与使用建议

  • 安装前请核对封装方向,确保焊接极性正确。
  • 在连续高电流或高功率场合,注意 PCB 散热设计,增大铜箔面积或加散热槽以降低结温。
  • 若在高频开关应用中使用,请评估恢复时间与开关损耗是否满足系统要求;对于对恢复特性敏感的场合,可考虑专用快速恢复或肖特基二极管替代方案。
  • 为保证长期可靠性,建议按时科的回流焊工艺规范(温度曲线、最大峰值温度)进行组装。

六、可靠性与测试

器件设计满足一般工业级可靠性要求,常见测试包括高温贮存、温度循环、潮湿试验与焊接耐热测试。使用过程中应避免超出额定反向电压与正向平均功耗,以免加剧漏电或热失效。

七、订购信息与支持

品牌:SHIKUES(时科) 型号:SK4001WA 封装:SOD-123FL 若需样品、批量报价或更详细的电气、热特性与封装尺寸图,请联系时科授权销售或查阅官方完整数据手册。

总结:SK4001WA 以低正向压降、低反向漏电和小型封装为主要优势,适合各类1A级别的整流与保护应用。针对具体系统要求,请结合完整数据手册与实际测试评估器件性能。

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
