DVIULC6-4SC6 产品概述

一、产品简介

DVIULC6-4SC6 是雷卯电子(Leiditech)推出的一款低电容、低泄漏的多通道瞬态抑制二极管(TVS),封装为 SOT-23-6。器件专为 USB 2.0 等高速数据线以及相关电源保护设计,能够在 ESD、浪涌和脉冲干扰下提供可靠的线路保护,同时对信号完整性的影响极小。

二、关键参数

  • 反向截止电压 Vrwm:5 V
  • 击穿电压 VBR:6 V(典型)
  • 峰值脉冲功率 Ppp:350 W @ 8/20 µs
  • 钳位电压(典型):15 V / 28 V(视通道与测试条件)
  • 反向泄漏电流 Ir:1 µA(nA 级别的超低泄漏)
  • 结电容 Cj:0.5 pF(低电容,适合高速信号)
  • 防护等级:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)

三、主要特性

  • 极低结电容(0.5 pF),对 USB 2.0 等高速差分信号影响极小,保证信号完整性。
  • 超低泄漏电流(nA 级/典型 1 µA),适用于电源敏感和待机应用。
  • 低钳位电压设计,在遭受 ESD/浪涌时能有效限制电压尖峰,保护下游器件。
  • 优异的峰值吸收能力(350 W @ 8/20 µs),可承受工业级冲击与脉冲。
  • 多标准兼容性:通过 IEC 61000-4-2(接触/空气放电 ±20 kV)、IEC 61000-4-4、IEC 61000-4-5 测试,满足系统级抗扰度要求。

四、典型应用

  • USB 2.0 数据线和 VBUS 电源保护(PC、笔记本、移动设备外设)
  • 机顶盒、数字电视(DTV)信号和电源防护
  • 工业接口与通信端口的 ESD 与浪涌防护
  • 其他对低电容、高速信号保护有要求的便携与嵌入式设备

五、应用建议与封装说明

  • 封装:SOT-23-6,适合表面贴装自动化生产。
  • 布局建议:器件应尽可能靠近受保护的连接器或接口放置,尽量缩短受保护信号线与器件之间的走线。接地端应采用低阻抗、大面积接地铜箔,并通过短距多点回流到系统地。
  • 不同通道钳位:在同一封装内,不同引脚通道可能对应不同钳位设计(例如数据线与电源线钳位略有差别),选型时请依据实际电源与信号电压选择合适型号。

六、可靠性与合规

DVIULC6-4SC6 设计并测试满足 IEC 61000-4 系列抗扰度标准,空气放电与接触放电均达 ±20 kV 要求,适合消费电子与工业级环境的长期稳定运行。器件在典型工业温度范围内具有良好的重复冲击承受能力与低老化特性。

七、选型与订购信息

  • 品牌:Leiditech(雷卯电子)
  • 封装:SOT-23-6
  • 型号:DVIULC6-4SC6
  • 推荐在产品数据手册中确认具体钳位曲线、浪涌测试波形及引脚功能以匹配系统需求。如需评估样片或进行电路验证,请联系供应商获取样品与参考设计资料。

若需要针对具体线路(如 USB D+/D-、VBUS、地线)给出接线图或参考 PCB 布局示意,可提供系统拓扑与约束参数,我方可给出更精确的设计建议。

Sourcing availability signal

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
