BV15C-ES 产品概述

一、产品简介

BV15C-ES 是 ElecSuper(静芯微)推出的一款单路双向 ESD 静电防护二极管,封装为 SOD-323,器件标识印字为“GBLC”。该器件针对高速通讯接口(尤其是 RJ45 千兆网口)设计,具备极低结电容(Cj = 0.8 pF)、高瞬态抗冲击能力(IEC 61000-4-2 静电放电与 IEC 61000-4-4 电快速瞬变兼容),能在保证信号完整性的同时对过电压瞬态进行有效钳位保护。

二、主要性能参数

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:15 V
  • 击穿电压 VBR(规范值):16.5 V
  • 钳位电压(典型):45 V(瞬态钳位)
  • 峰值脉冲电流 Ipp:5 A(单次脉冲条件)
  • 峰值脉冲功率 Ppp:300 W
  • 反向电流 Ir:1 μA(常温)
  • 结电容 Cj:0.8 pF(低电容,适合高速差分信号)
  • 通道数:单路
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 抗扰等级:符合 IEC 61000-4-2(静电)与 IEC 61000-4-4(电快速瞬变)
  • ESD 耐受能力:高达 30 kV(人体模式/指定测试条件下)
  • 封装:SOD-323
  • 印字:GBLC
  • 品牌:ElecSuper(静芯微)

三、产品特点(亮点)

  • 低结电容(0.8 pF):对高速差分信号几乎无影响,适用于千兆以太网与其他高速接口。
  • 双向保护:可防止正负向电压瞬态,方便用于差分对或对地保护。
  • 高钳位能力:45 V 钳位电压在瞬态时提供可靠的电压限制,保护下游敏感芯片。
  • 高瞬态功率承受:300 W 峰值脉冲功率、5 A 峰值脉冲电流,能处理常见的 ESD 与浪涌事件。
  • 宽工作温度:适应工业级温度范围(-40 ℃ ~ +125 ℃)。

四、典型应用

  • RJ45 千兆以太网接口保护(单独或并联用于差分对保护)
  • 高速数据接口与网络通讯模块
  • 网口变压器两端与磁芯附近的瞬态保护
  • I/O 口、通信端口的静电防护
  • 便携式与工业设备中对信号引脚的 ESD 防护

五、应用建议与布局要点

  • 放置位置:将 BV15C-ES 尽量靠近受保护的连接器(例如 RJ45 插座)布置,以缩短暴露于线路上的未保护走线长度,降低寄生电感。
  • 接地:确保保护器的接地面/回流路径短而宽,使用旁边多颗过孔(via)将地平面快速连接至器件背后的散流层,减少钳位时的回流阻抗。
  • 差分对保护:在需要保护差分对(如 RJ45)时,可选择将双向 TVS 并联于差分对两线之间,利用其低电容特性对差模瞬变直接钳位;同时配合共模滤波器或浪涌抑制器对共模干扰做进一步处理。
  • 串联元件:在某些设计中可与磁性元件、变压器或共模电感配合使用,以提高系统整体抗扰度。
  • 焊接工艺:遵循 SOD-323 的常规 SMT 回流温度曲线,避免长时间高温暴露。

六、可靠性与合规

BV15C-ES 设计满足 IEC 61000-4-2(ESD)与 IEC 61000-4-4(EFT)等工业级抗扰标准,具备 30 kV 静电耐受能力(按厂家测试条件)。低漏电流(Ir = 1 μA)保证在静态工作时对系统功耗影响极小。工作温度范围覆盖典型工业应用环境,可适用于苛刻工作条件。

七、封装与标识

  • 封装型号:SOD-323,适合自动化贴片组装,节省 PCB 面积。
  • 印字标识:GBLC,便于生产与维护时的元器件识别。
  • 单路设计:每个器件对应一个信号通道的保护。

八、选型与采购建议

  • 型号命名示例:BV15C-ES(ElecSuper,SOD-323,单路双向 TVS)
  • 在 RJ45 千兆防护方案中,推荐在每对差分线上优先考虑低电容双向 TVS,以兼顾高速信号完整性与瞬态保护能力。
  • 量产时建议与供应商确认最新的器件批次、可靠性数据与推荐回流焊接曲线。

九、注意事项

  • 虽然器件具备高能量吸收能力,但多次或超规格的冲击会降低器件寿命,设计中应考虑冗余或配套浪涌分流方案(如气体放电管、浪涌抑制器)。
  • 使用时应关注器件两端的最大额定电压与系统正常工作电压,避免长期在临界电压下工作导致漏电或漂移。
  • 在高频高速线路中,布线长度、阻抗匹配同样决定信号质量,保护器仅作为瞬态事件的防护手段而非信号调理器件。

如需针对具体以太网接口拓扑(8P8C RJ45)提供参考接线与防护方案图或 PCB 布局范例,可提供具体电路环境与布板图,我可据此给出更详细的实用建议。

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
