SR05-4A 是东沃(DOWO)推出的一款四路单向ESD保护器件,采用SOT-23-6小外形封装,专为保护高速数据线和低压电源节点免受静电放电(ESD)和脉冲浪涌损害而设计。器件在保持极低寄生电容的同时,提供高能量吸收能力与低漏电流,特别适合对信号完整性和功耗敏感的便携及工业电子设备。
SR05-4A 采用 SOT-23-6 小型封装,便于表面贴装与自动化生产。封装允许将保护器件靠近受保护的连接器或信号引脚放置,以缩短回路路径并提高保护效果。具体引脚功能与连接方式请参阅器件数据手册,以确定每一路信号线与公共接地引脚(或公共电源引脚)的布线关系。
SR05-4A 5.5A 四路单向 ESD 保护器件以其高能量吸收能力、低结电容与小型化封装,成为对高速信号与低压接口实施近端保护的理想选择。对于需要在有限空间内保护多个信号线且对信号完整性要求较高的消费电子、通信与工业设备,SR05-4A 提供了平衡的性能与可集成性。选择时请根据系统工作电压、最大可承受浪涌能量以及PCB布局条件综合评估,必要时参考样片测试与制造商的应用说明。

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.
