SENC3D5V1BC 产品概述

一、产品简介

SENC3D5V1BC 是 ElecSuper(静芯微)推出的一款小封装单路、双向 ESD 防护器件,封装为 SOD-323,专为音频、视频及通信接口的静电及浪涌防护而设计。器件在静电放电(IEC 61000-4-2)测试中可达 ±30kV 保护等级,具有低结电容、低漏电及快速钳位特性,适用于高速信号线的末端保护与接口防护场合。

二、主要特点

  • 极性:双向(Bidirectional),可对正负极性冲击提供对称钳位
  • 额定反向截止电压 Vrwm:5.0 V
  • 击穿电压 VBR:6.0 V(典型)
  • 钳位电压(Ipp = 8 A,8/20 µs):11 V(典型)
  • 峰值脉冲电流 Ipp:8 A(8/20 µs)
  • 峰值脉冲功率 Ppp:150 W(8/20 µs)
  • 反向漏电流 Ir:1 µA(在 Vrwm 下)
  • 结电容 Cj:典型 ~12 pF,约 15 pF 量级(低电容设计,利于高速信号完整性)
  • 通道数:单路(Single channel)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 防护等级:满足 IEC 61000-4-2(±30 kV)静电标准
  • 封装:SOD-323,表面贴装,体积小、可在有限空间内布局

三、典型应用场景

  • 音频、视频接口(如耳机接口、视频输入/输出端口)
  • 通信接口(串口、低速网络、控制总线等)
  • 移动设备、便携式设备的外部接口防护
  • 接口模块、连接器附近的末端保护,避免静电和感应浪涌损坏敏感芯片

四、应用要点与电路连接建议

  • 双向器件可直接并联于信号线与地之间用于单端信号的正负极性保护;对于差分信号,可将器件置于差分对之间以限制对地冲击。
  • 建议放置位置:靠近外部连接器(如插口、I/O 引脚)并尽量靠近受保护器件的引脚,缩短引线长度以降低寄生感抗和提高防护效率。
  • PCB 布局建议:器件与地线之间应尽量采用固体地平面,并保证器件引脚至地的铜箔短且宽;避免通过狭窄走线连接到地,必要时在器件下方或附近设置过孔引通至内部大面积地层,有利于散热与瞬态能量分散。
  • 对高速信号:低结电容(典型 12 pF)有助于维持信号完整性,但在非常高速或高精度差分总线(如 USB3.0/PCIe)仍需评估是否满足系统要求。

五、可靠性与测试

  • ESD 性能:通过 IEC 61000-4-2 等级测试,器件能承受 ±30 kV 静电冲击,为用户提供可靠的接口防护能力。
  • 浪涌承受能力:在 8/20 µs 测试波形下,器件能承受 150 W 峰值功率和 8 A 峰值脉冲电流,适合常见的雷击感应及供电瞬态事件防护需求。
  • 宽温工作范围:-55 ℃ 到 +150 ℃ 的工作温度确保在极端环境下仍能保持防护性能。

六、封装与选型建议

  • 封装:SOD-323,适合表面贴装工艺和紧凑型 PCB 布局。
  • 选型建议:若需保护高速差分对或更低电容需求,可参考更低 Cj 的型号;若需更高浪涌能力,则应选用功率等级更高的器件或并联布局并配合合理的 PCB 防护设计。
  • 进一步资料:在量产前建议参考完整器件数据手册进行电气特性、钳位曲线和典型电路验证,并在目标系统进行实际的 ESD/浪涌测试。

七、总结

SENC3D5V1BC 是一款面向音视频及通信接口的紧凑型单路双向 ESD 防护器件,具有典型 5 V 工作电压、低漏电、低结电容及较强的瞬态吸收能力(150 W@8/20 µs,Ipp 8 A),并通过 IEC 61000-4-2 ±30 kV 级别验证。其小封装 SOD-323 适合在空间受限的应用中提供可靠的静电与浪涌保护。选型和布板时请结合完整数据手册和系统信号要求进行验证,以确保达到最佳防护效果。

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
