DSK115 产品概述

一、产品简介

DSK115 是 MDD 推出的独立式肖特基整流二极管,封装为 SOD-123FL,面向对开关损耗、反向耐压和温度稳定性有要求的工业与消费类电源应用。器件在 1A 电流工况下的正向压降为 850mV(典型测试条件:If=1A),反向耐压(Vr)为 150V,反向漏电流在 150V 时为 100µA,工作结温范围为 -55℃ 至 +150℃。

二、主要特性

  • 正向压降 Vf = 850mV @ If = 1A(中等压降,兼顾导通损耗与高压耐受能力)
  • 最大直流整流电流:1A(连续工作条件)
  • 直流反向耐压 Vr = 150V,适用于较高电压回路的整流与保护
  • 反向电流 Ir = 100µA @ 150V(低漏流,利于高压下的静态损耗控制)
  • 工作结温范围:-55℃ ~ +150℃,满足工业级温度需求
  • 封装:SOD-123FL,低剖面、表贴型,便于自动化贴装

三、封装与机械优势

SOD-123FL 封装具有低高度、较小占板面积和良好引脚热传导特性,适合空间受限的电源模块与通讯设备。平坦封装便于高速贴片与回流焊接,铜箔焊盘设计能通过增加焊盘面积提高热散能力。

四、典型应用

  • 开关电源(次级整流、辅助电源)
  • DC-DC 转换器输出整流与同步整流替代件
  • 反向极性保护、输入浪涌钳位与续流回路
  • 便携式设备、电池管理与充电器线路(需考虑工作电压范围)
  • 工业控制与通信设备的高压整流场合

五、设计与布局建议

  • 布局时应缩短二极管至电源电感与电容的回路长度,减少寄生电感导致的尖峰电压。
  • 适当扩大焊盘铜箔以提高热阻散能力,必要时在底层增加过孔或热沉铜。
  • 在高电压开关环境中,建议配合吸收网络(RC、RCD)或 TVS,以限制浪涌与开关过冲。
  • 考虑反向漏流对静态功耗的影响,在高阻抗或休眠电路中评估 Ir 对电池寿命的影响。

六、可靠性与工艺兼容

DSK115 可在常见无铅回流焊工艺下使用,推荐遵循 IPC/JEDEC 的回流曲线及制造商的焊接说明。器件的宽工作结温使其适合工业环境,但应避免长期在极端高温和高反向电压下连续工作以延长寿命。为保证批次一致性,建议在关键设计中进行样片老化与热循环验证。

七、选型提示与对比

  • 若需更低正向压降以减少导通损耗,可考虑低 Vf 型肖特基(但通常耐压较低)。
  • 若系统主要关注高压耐受与低静态漏流,DSK115 在 150V 等级中提供了平衡的选项。
  • 在并联使用时应注意正向压降匹配与热均衡,避免单只过热。

八、总结

DSK115 为一款面向工业与消费类电源的 150V / 1A 肖特基整流二极管,具有中等正向压降、较低反向漏流和宽温度范围,封装为易贴装的 SOD-123FL。适合用作高压整流、极性保护和高频整流场合,设计时注意热管理与浪涌保护即可发挥其性能优势。若需器件详细数据表(含绝对最大额定值、包装信息及回流曲线),请参考 MDD 官方资料或联系供应商获取完整技术手册。

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
