DS220W是晶导微电子推出的中低压大电流肖特基整流器件,采用SOD-123FL表面贴装封装,针对低功耗、高可靠性整流场景优化设计,核心参数覆盖2A持续整流电流、200V反向耐压、950mV低正向压降,可广泛应用于消费电子、工业控制、汽车电子等领域,是传统硅整流管的高效替代方案。
DS220W定位为中小功率高效整流器件,核心价值体现在三方面:
DS220W的参数设计精准匹配实际应用需求,核心参数及意义如下:
正向压降(Vf):950mV@2A
肖特基二极管的核心优势是低正向压降,DS220W在2A持续电流下仅950mV,较传统硅整流管(如1N4007的1.1V@1A),同等电流下导通损耗降低约18%。以5V/2A充电器为例,该参数可使输出整流损耗从2.2W降至1.9W,减少散热需求,缩小产品体积。
直流反向耐压(Vr):200V
满足中低压系统(12V、24V、48V)的耐压需求,可用于AC-DC整流输出(如220VAC转24VDC的次级整流)、反接保护电路,避免反向电压击穿。
平均整流电流(Io):2A
持续工作电流能力覆盖大部分中小功率应用,如LED驱动电源(24V/2A灯带)、小型工业电源模块。
反向漏电流(Ir):300uA@200V
反向截止时漏电流极小,待机功耗低,适合智能穿戴、物联网模块等低功耗场景(待机时反向漏电流仅0.06W@200V)。
非重复峰值浪涌电流(Ifsm):40A
可承受瞬间大电流冲击(如电源开机浪涌、负载突变),提升产品可靠性。例如车载充电器开机时的浪涌电流可达30A以上,DS220W的40A浪涌能力可有效避免失效。
工作结温范围:-55℃~+150℃
宽温设计适应极端环境,满足工业级(-40℃~85℃)、车载(部分场景)及户外设备的温度需求,结温150℃时仍能稳定工作。
DS220W采用的SOD-123FL封装具备以下特点:
DS220W的参数适配多领域需求,典型应用包括:
晶导微电子作为国内功率器件龙头厂商,DS220W具备完善的品质体系:
总结:DS220W凭借低损耗、高可靠性、小封装的综合优势,成为中小功率整流场景的高性价比选择,可有效提升终端产品的效率与稳定性,适配多领域的量产需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
