DSK26 肖特基二极管 产品概述

一、产品概述

DSK26 为 TWGMC(台湾迪嘉)出品的独立式肖特基整流二极管,采用低轮廓 SOD-123FL 封装,面向中功率整流与保护场景。器件具有较低的正向压降与快速切换特性,适用于开关电源、降压/升压变换器、反向保护与续流回路等需要高效率与低损耗的应用。

二、主要参数

  • 器件类型:肖特基二极管(独立式)
  • 型号:DSK26
  • 正向压降 Vf:0.7 V @ IF = 2 A
  • 直流反向耐压 Vr:60 V
  • 连续整流电流 IF(AV):2 A
  • 非重复峰值浪涌电流 Ifsm:40 A(单次脉冲)
  • 反向电流 Ir:500 μA(典型/最大值,参考厂方测试条件)
  • 工作结温范围:-55 ℃ ~ +125 ℃
  • 封装:SOD-123FL(表面贴装)

三、关键特性与优势

  • 低正向压降(0.7 V @2 A):在中等电流条件下降低导通损耗,提高整体转换效率,适合对效率敏感的电源设计。
  • 快速切换、肖特基特性:恢复时间极短,降低开关损耗及开关尖峰,适合高频电源应用。
  • 封装紧凑、热性能良好:SOD-123FL 体积小、适合高密度装板,同时对热量有一定散逸能力,便于自动化贴装。
  • 耐压 60 V:覆盖常见的中低压直流系统,如24 V/48 V 总线与汽车电子低压侧保护场景。
  • 抗冲击能力:40 A 的单次浪涌耐受能力适应启动浪涌或短时异常脉冲。

四、典型应用

  • 开关电源二次整流与同步整流替代方案
  • DC-DC 降压/升压转换器整流、续流二极管
  • 反向极性保护、输入浪涌与钳位保护
  • LED 驱动、电池充放电路径与电源管理模块
  • 工业与通信设备的中低压电源整流

五、使用与电路布局建议

  • 布局靠近功率开关:将 DSK26 放置在开关元件与负载之间的最短回路中,减小寄生电感与 EMI。
  • 增大铜箔散热面积:对承载 2 A 持续电流的布线使用较宽铜迹或加大铜箔以提升散热能力,必要时在底层做散热过孔。
  • 考虑逆向漏电随温度上升增加:在高温工况下反向电流会升高,设计时对漏电容忍度应预留裕量。
  • 浪涌与保护:尽管 Ifsm 可承受单次浪涌,仍建议在易受大浪涌的场合配合限流或熔断保护。

六、注意事项与可靠性

  • 工作环境温度与功率耗散需考虑结温上升,建议在高温条件下适当降额运行以延长可靠性。
  • 反向耐压 60 V,超压时可能导致击穿或永久损伤,电路应保证正常工况不超过该值。
  • 焊接工艺请参考 SOD-123FL 封装的回流曲线,避免过高的峰值温度或长时间热暴露影响器件性能。

七、封装与订购信息

  • 封装形式:SOD-123FL,适合自动贴片与回流焊流程。
  • 品牌:TWGMC(台湾迪嘉),型号标识 DSK26。
  • 建议向授权分销或厂商索取完整数据手册(Datasheet)以获取器件在不同测试条件下的详细曲线、热阻参数与推荐焊接工艺。

如需我帮您根据具体工作点(电压、电流、频率、温度)进行热设计、散热方案或替代器件筛选,我可以提供更详细的计算与布局建议。

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
