DSK24W 肖特基二极管产品概述

一、产品基本信息

DSK24W是富信电子(FOSAN)推出的一款低压肖特基整流二极管,专为中小功率、高密度电路设计。该器件采用SOD-123FL表面贴装封装,体积紧凑,具备低正向压降、宽温适应性等核心特点,广泛适用于消费电子、汽车电子及工业控制等领域的低压整流/续流场景。

二、核心电气性能参数

DSK24W的关键参数明确了其性能边界,直接支撑实际应用场景的选型:

  1. 正向压降(Vf):[email protected](典型值)——在额定连续电流下,正向压降仅0.7V,显著降低导通损耗,提升电源转换效率(尤其适合5V/12V低压系统);
  2. 直流反向耐压(Vr):40V——覆盖常见低压电源拓扑(5V/12V/24V),满足基本耐压需求;
  3. 额定整流电流(If):2A(直流)——持续工作电流能力稳定,可支撑中小功率负载的整流需求;
  4. 反向漏电流(Ir):100μA@40V(最大值)——反向漏电流极低,减少反向待机损耗,同时提升长期工作可靠性;
  5. 工作结温范围:-65℃~+150℃——宽温设计适应极端环境(如汽车发动机舱、工业低温/高温区域),环境适应性强。

三、封装与可靠性设计

DSK24W采用SOD-123FL表面贴装封装,具备以下设计优势:

  • 小体积高密度:封装尺寸紧凑(典型尺寸约2.4mm×1.6mm),可有效节省PCB布局空间,适配便携式设备、小型电源模块等高密度场景;
  • 耐高温可靠性:封装材料符合无铅(Pb-free)及RoHS环保标准,可承受最高150℃结温,长期工作无封装老化问题;
  • 工艺兼容性:支持回流焊、波峰焊等常规表面贴装工艺,焊接可靠性高,不易出现虚焊/脱落问题。

四、典型应用场景

结合性能特点,DSK24W的核心应用场景包括:

  1. 低压直流电源:5V/12V开关电源、USB充电器、移动电源的整流电路(利用低Vf降低损耗,提升效率);
  2. LED驱动电路:小功率LED照明(台灯、指示灯)的续流/整流环节(避免反向电压损害LED);
  3. 汽车电子模块:车载小功率系统(仪表盘背光、传感器电源)的整流电路(宽温设计适应舱内温度变化);
  4. 工业控制模块:PLC、传感器接口的辅助电源整流(低漏电流确保待机功耗合规);
  5. 消费电子设备:蓝牙耳机、智能手表等便携式设备的充电电路(小封装适配设备小型化需求)。

五、产品优势总结

DSK24W相比同类低压肖特基二极管,具备以下核心竞争力:

  • 高效节能:低正向压降(0.7V@2A)大幅降低导通损耗,提升电源转换效率;
  • 宽温可靠:-65℃~+150℃结温范围,适应极端环境应用;
  • 小体积适配:SOD-123FL封装节省PCB空间,支撑设备小型化设计;
  • 低损耗长寿命:100μA@40V反向漏电流,减少反向损耗,延长器件寿命;
  • 环保合规:符合无铅、RoHS标准,满足全球市场环保要求。

该器件通过平衡“小体积、低损耗、宽温可靠”三大核心需求,成为低压中小功率整流场景的高性价比选择。

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
