LM-CDSOT236-0504C 产品概述

一、产品简介

LM-CDSOT236-0504C 是 Leiditech(雷卯电子)推出的一款四路低电容瞬态电压抑制器(TVS),专为 USB 2.0 等高速数据接口和 5V 电源线的电磁兼容(EMC)保护设计。器件采用 SOT-26 封装,集成四路保护通道,具备超低泄漏、极小结电容与高能量吸收能力,适用于机顶盒、数字电视、消费类电子等对信号完整性和可靠性要求较高的场景。

二、主要规格(摘要)

  • 型号:LM-CDSOT236-0504C
  • 品牌:Leiditech(雷卯电子)
  • 类型:TVS 二极管,四路
  • 封装:SOT-26
  • 反向工作电压 Vrwm:5 V
  • 击穿电压 VBR:6 V
  • 钳位电压(典型/最大):28 V
  • 峰值脉冲功率 Ppp:350 W(8/20 µs 浪涌脉冲)
  • 反向漏电流 Ir:1 µA(nA 级别泄漏称述则表明非常低)
  • 结电容 Cj:0.5 pF(单通道)
  • 通道数:4 路
  • 符合标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)

三、关键特性

  • 超低泄漏:器件在 5 V 工作条件下,反向漏电流极低(典型 1 µA),有利于降低功耗并保持线路静态性能。
  • 极低结电容:单通道约 0.5 pF,非常适合 USB 2.0 等高速差分信号线路,保证信号完整性与高速传输可靠性。
  • 高能量吸收能力:350 W(8/20 µs)峰值脉冲功率,能有效吸收电气浪涌与瞬态冲击,保护后端电路。
  • 低钳位电压:最大钳位电压约 28 V,能够在浪涌事件中将受保护节点电压限制在安全范围,减少对被保护器件的应力。
  • 多重抗扰度认证:通过 IEC 61000-4-2 空气/接触放电 ±20 kV、IEC 61000-4-4(电快速瞬变脉冲)以及 IEC 61000-4-5(浪涌)要求,适用较为苛刻的工业与民用抗干扰场景。

四、典型应用

  • USB 2.0 数据线与电源保护(D+/D-、VBUS、GND 等)
  • 机顶盒、数字电视前端接口保护
  • 消费类电子设备的外部接口(如 HDMI 辅助线路、RJ45 未受保护线路等)
  • 任何需要在 5 V 系统中同时兼顾高速信号完整性与 ESD/浪涌保护的场合

五、设计与布局建议

  • 尽量将 LM-CDSOT236-0504C 放置在受保护连接器(USB 插座等)附近,缩短信号线与 TVS 之间的走线长度,以提高保护效率。
  • 接地布局要稳固:TVS 的地端应采用低阻抗回路连接至系统地,必要时旁路铜箔和多孔过孔以降低接地电感。
  • 对高速差分对(如 USB D+/D-)保持对称走线,避免在 TVS 位置引入不对称或额外阻抗。0.5 pF 的超低结电容可最大限度减小对信号质量的影响,但仍建议在实际 PCB 设计中进行信号完整性验证(眼图/抖动测试)。
  • 在受高能量浪涌或重复冲击环境下,配合输入熔断保护或防浪涌器件可进一步提升系统鲁棒性。

六、封装与采购信息

  • 封装形式:SOT-26,适合表面贴装工艺,体积小且便于在有限空间内实现多路保护。
  • 型号标识:LM-CDSOT236-0504C(四路、5 V 工作电压)
  • 适用行业:消费电子、机顶盒与广播设备、通信终端及通用接口保护方案。

七、小结

LM-CDSOT236-0504C 将超低漏电、极小结电容与高能量吸收能力集成于紧凑的 SOT-26 封装,适合对信号完整性要求高且需可靠抗静电/浪涌保护的 5 V 系统。其通过 IEC 61000-4-2/4-4/4-5 等标准验证,能为 USB 2.0 等高速数据及电源线路提供高效的防护,是机顶盒、数字电视及消费类电子接口保护的理想选择。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
