LESD8D3.3CAT5G 是 UMW(友台半导体)推出的一款针对数据线和接口保护的 TVS(瞬态电压抑制器)器件。器件为双向工作模式,工作电压(Vrwm)为 3.3V,击穿电压约为 6.5V,钳位电压在峰值脉冲条件下约为 10V,峰值脉冲电流 Ipp 为 6A,反向静态电流仅 100nA,结电容 Cj 约为 16pF,封装为 SOD-882。防护等级满足 IEC 61000-4-2 标准要求,适合对以太网、通信接口和各种差分高速信号线的浪涌与静电放电保护。
LESD8D3.3CAT5G 针对静电放电与浪涌进行了优化,防护等级符合 IEC 61000-4-2 要求。器件在正常使用环境下具备良好的重复冲击能力和长期稳定性;在应用前建议根据目标系统的浪涌能量等级做实际脉冲测试,确认钳位点与下游器件安全裕度。
总结:LESD8D3.3CAT5G 在 3.3V 系统中为接口与数据线提供可靠的双向瞬态保护,体积小、漏电低,适合多数 CAT5 类应用。设计时需关注结电容对高速信号的影响以及器件在目标脉冲条件下的钳位表现。

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.
