ESD3V3D3(品牌:ElecSuper / 静芯微)是一款单路、单向的瞬态电压抑制器,专为3.3V工作电压系统的静电放电(ESD)保护而设计。器件采用SOD-323小封装,具备高能脉冲吸收能力和宽工作温度范围,适用于对体积、成本和防护性能有要求的便携和嵌入式系统。
ESD3V3D3 为单向 ESD 防护二极管,反向截止电压 Vrwm = 3.3V,适配典型 3.3V 信号和电源轨。器件在遭受静电冲击或脉冲干扰时能迅速导通,将能量导入地或电源侧,保护后端电路免受高压瞬变损害。SOD-323 封装利于表面贴装加工与体积受限的应用。
性能亮点:该器件在 8/20 µs 波形下可承受高达 450 W 的瞬态功率,能快速钳位并吸收高达 25 A 的瞬变电流,适合对抗瞬时静电放电或脉冲干扰。
注意:由于结电容较大(约 200 pF),该器件不推荐用于对信号完整性有严格要求的高速接口(如 USB 2.0/3.x、HDMI、MIPI 高速通道),更适合电源线或低速信号保护。
总结:ESD3V3D3 以小封装、高脉冲能量吸收能力和适配 3.3V 系统的电压特性,适合用于电源轨与低速信号线的有效静电防护。设计时需综合考虑其较高的结电容对信号完整性的影响,并采用合理的 PCB 布局与接地方案以发挥最佳保护效果。若需批量采购或获取详细数据手册(包括典型特性曲线和封装尺寸),建议联系 ElecSuper(静芯微)或授权分销商获取官方资料。

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.
