ULC0511CDN 是 Leiditech(雷卯电子)推出的一款用于瞬态过电压保护的 TVS(瞬态电压抑制)二极管,封装为 X1-DFN1006-2(小型 DFN 贴片封装),专为 5V 及高速信号线的静电和浪涌保护而设计。该器件具备低结电容(Cj = 0.35 pF)、低漏电(Ir = 1 μA)与较高的峰值脉冲吸收能力(Ipp = 3 A),并满足 IEC 61000-4-2、4-4、4-5 抗扰度要求,适合便携设备、接口保护与高频数据链路的应用。
X1-DFN1006-2 为超小型 DFN 贴片封装,推荐在 PCB 上为热焊盘与接地焊盘预留规范焊盘尺寸,并在焊盘周围保留良好的散热铜箔与过孔,确保脉冲能量能够快速导入地平面。焊接时使用回流焊工艺并控制温度曲线,避免长时间暴露在高温下。
ULC0511CDN 在设计上面向通过 IEC 61000-4-2/4-4/4-5 等抗扰度测试的应用场景。实际系统通过性还依赖于 PCB 布局、搭配元件与整体接地设计。对关键产品建议在实物样机上进行完整的抗扰度试验验证。
总结:ULC0511CDN 以其低电容、低漏电和小型封装优势,适合移动与高速信号接口的瞬态保护。在选择时应关注其 3 A 的吸收能力与 30 V 的钳位水平,结合系统需求与板级布局,确保在目标应用中提供可靠的过电压防护。

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.
