UMW(友台半导体)作为国内功率半导体与防护器件领域的专业厂商,其推出的CESD5V0D5是一款针对低电压系统定制的单向ESD(静电放电)防护二极管,凭借紧凑封装、可靠防护能力及符合国际标准的特性,成为消费电子、IoT等小型化设计场景的常用选择。
CESD5V0D5属于单向ESD防护器件,专为5V供电系统的静电防护需求打造,采用超小型SOD-523封装,可直接并联在电源或信号线路中。当静电放电事件发生时,器件快速导通并钳位过压,保护后端敏感元件(如MCU、传感器)免受损坏,同时不影响系统正常工作。
封装尺寸约1.6mm×0.8mm×0.6mm,体积仅为传统SOT-23的1/3,可轻松集成到智能手机、智能手环等空间受限设备中,满足小型化设计需求。
通过IEC 61000-4-2静电放电测试,可抵御接触放电(8kV)与空气放电(15kV),符合消费电子、IoT领域的防护要求,可靠性有明确标准支撑。
单向导通特性适配单方向静电防护场景,如电源输入端口(仅需防护外部→内部静电)、单向信号线路(如USB充电端),无需额外反向防护电路,简化设计。
CESD5V0D5广泛应用于:
UMW CESD5V0D5是一款高性价比的单向ESD防护二极管,以紧凑封装、可靠防护及低漏电流特性,完美适配5V系统的小型化设计,覆盖消费电子、IoT等主流场景,是工程师静电防护设计的实用选择。

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.
