ESD9X3.3ST5G 是由 TECH PUBLIC(台舟电子)提供的一款用于静电放电(ESD)与浪涌(Surge)保护的瞬态电压抑制器(TVS)。器件基准电压为3.3V,采用超小型 SOD-923 封装,适用于对板级保护、接口与电源线的可靠防护需求。
本器件提供高能量吸收能力与快速响应的浪涌/静电抑制。低漏电流(Ir)有利于降低待保护电路静态功耗;适中的结电容(90pF)在多数低速或中速数字/模拟接口上不会显著影响信号完整性。SOD-923 封装支持自动贴片与高密度布局。
适用于 3.3V 电源轨及周边接口防护,包括单板计算机、嵌入式模块、传感器接口、串口/I²C/SPI 线缆接口、工业控制终端及其它需满足 IEC 静电/浪涌抗扰度的场合。对极高速差分线(如 PCIe/USB3.x)需评估结电容对链路的影响后再选型。
工作温度范围宽(-55℃~+125℃),适应工业级环境;通过 IEC 61000-4-2 与 IEC 61000-4-5 等电磁兼容性测试标准,能在实际产品中提供稳定的浪涌与静电防护能力。
在选型时重点核对工作电压(Vrwm 3.3V)、钳位电压与最大脉冲功率是否满足系统最大浪涌能量要求,评估结电容对信号链路的影响并考虑封装与PCB布局约束。若需更低电容或更高能量吸收,应对比同系列或其它型号进行权衡。

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.
