LESD9D3.3CT5G 是乐山无线电(LRC)推出的一款双向瞬态电压抑制器(TVS)——ESD 二极管,专为 3.3V 工作电压的接口及信号线提供静电放电和瞬态浪涌保护。器件封装为 SOD-923,体积小、易于贴片,适合集成在空间受限的移动设备、通信终端和工业控制板上。
该器件在 8/20µs 波形下能承受 11.2A 的峰值冲击电流,配合 14.1V 的钳位电压能在大多数瞬态事件中把能量限制在安全范围内;低至 1µA 的反向漏电保证对电源和高阻态电路影响小;25pF 的结电容使其适用于多数数据信号线,但对极高频率或超高速差分信号仍需评估是否满足系统带宽要求。
SOD-923 小封装利于贴片自动化生产。为了获得最佳防护效果,应将 LESD9D3.3CT5G 放置于靠近被保护接口或连接器处、走线最短且回流路径宽短的版图位置;接地垫应尽可能靠近器件并通过足够数量的过孔与主地平面相连,减少寄生感抗与回流环路面积。
在高能量冲击环境或反复冲击工况下,应评估器件的累积功耗承受能力并结合系统熔断或限流措施。焊接建议采用符合工业回流曲线的工艺,避免超出制造商给定的温度-时间规范。存储与使用时注意防潮、防静电,避免长期在极限温度或高湿环境下工作导致性能漂移。

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.
