DS26W是晶导微电子推出的一款低压肖特基势垒二极管,专为低功耗、小体积整流应用设计,具备低正向压降、高持续电流能力、宽温可靠性等核心优势,适配消费电子、工业控制等多领域场景。
DS26W聚焦中低功率整流需求,主打“高效、紧凑、抗冲击”三大核心特性:
DS26W的核心参数围绕“效率与可靠性”优化,具体解析如下:
正向压降(Vf):700mV@2A
测试条件为2A正向电流下,低Vf可显著降低导通损耗(公式:P=Vf×If)——2A电流下损耗仅1.4W,适合对电源效率敏感的场景(如手机充电器、智能音箱)。
直流反向耐压(Vr):60V
满足5V/12V/24V等低压电源系统的反向耐压需求,避免反向电压击穿,适配多数消费电子及工业辅助电源。
直流整流电流(If):2A
持续工作电流能力,支持单颗器件为2A负载供电(如小型开关电源的主整流回路),无需并联多颗器件,简化电路设计。
反向漏电流(Ir):500uA@60V
60V反向电压下漏电流仅500μA,降低反向待机损耗,提升系统待机效率(如路由器、机顶盒的待机模式)。
非重复峰值浪涌电流(Ifsm):50A(8.3ms半波脉冲)
可耐受电源启动瞬间的大电流冲击,避免浪涌导致的器件损坏,提升电路可靠性(如汽车USB充电口、工业电源启动)。
工作结温范围:-55℃~+125℃
符合工业级温度标准,可在户外、高温车间等极端环境稳定工作,无性能衰减。
DS26W采用的SOD-123F封装具备以下优势:
DS26W的参数特性使其适配以下场景:
晶导微电子作为国内功率半导体领先企业,为DS26W提供全流程品质支持:
DS26W凭借高效、紧凑、可靠的特性,成为中低功率整流应用的优选器件,是晶导微电子在低压功率器件领域的代表性产品之一。
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.
