LM-ULC0544P10是雷卯电子(Leiditech)推出的四路集成式过压防护器件,专为低电压(3.3V/5V)高速信号接口设计,核心解决电子设备中静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌冲击的防护需求。产品通过优化结电容、集成多路通道及符合国际EMC标准,平衡了“防护可靠性”与“信号完整性”,适合对小型化、高速传输有要求的消费电子、工业控制及通信设备领域。
电压与功率防护能力
反向截止电压(Vrwm)为5V,精准适配主流3.3V/5V系统的工作电压范围,正常工作时不导通,避免对信号造成干扰;峰值脉冲电流(Ipp)达5A(8/20μs波形),可有效泄放雷电感应、电源切换等产生的浪涌电流;峰值脉冲功率(Ppp)60W,具备足够功率容限应对瞬态冲击,防止后端芯片被击穿。
信号完整性保障
结电容(Cj)仅0.45pF,远低于普通TVS管的电容值(通常>1pF),可最大程度减少对高速信号的传输损耗、延迟及上升沿畸变——例如对USB 3.0(5Gbps)、HDMI 2.0(18Gbps)等高速接口,能保证信号质量不衰减,满足1Gbps以上传输要求。
低功耗与可靠性
反向漏电流(Ir)仅200nA,几乎不消耗系统待机功耗,避免对敏感电路(如低功耗MCU)造成额外负担;钳位电压11V,在浪涌发生时可快速将电压钳位至安全范围(远低于芯片典型最大耐压15V),实现“瞬间防护”。
产品严格符合IEC 61000-4系列核心EMC标准,覆盖设备全场景防护:
封装形式:采用DFN2510-10封装,尺寸仅2.5mm×1.0mm×0.5mm(典型值),10引脚集成4路防护通道,大幅减少PCB占用空间,适合智能手机、智能穿戴等小型化产品的高密度布局。
典型应用:
LM-ULC0544P10通过“高集成度+低电容+宽标准覆盖”,为高速接口提供可靠防护,同时满足小型化产品的设计需求,是消费电子、工业领域的高性价比防护方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
