FSJEB05C 产品概述

FSJEB05C 是富芯森美(FUXINSEMI)推出的一款针对 5V 工作电压系统设计的双向瞬态抑制二极管(TVS),封装为 SOD-323,专为手机、移动配件及基于微处理器的设备提供高效的静电与浪涌保护。器件在 8/20μs 工况下具有高达 360W 峰值脉冲功率能力,并在低漏电、低结电容条件下兼顾高速信号完整性。

一、主要特性

  • 极性:双向(适用于正负瞬态对称抑制,支持双向 I/O 线保护)
  • 工作电压(Vrwm):5V(反向截止电压)
  • 击穿电压(VBR):8V
  • 钳位电压(Vclamp):≈20V(典型)
  • 峰值脉冲电流(Ipp):18A @ 8/20μs
  • 峰值脉冲功率(Ppp):360W @ 8/20μs
  • 反向漏电流(Ir):1μA(在 Vrwm 条件下)
  • 结电容(Cj):0.6pF(低电容,兼顾高速信号)
  • 通道数:单路
  • 防护等级:符合 IEC 61000-4-5(浪涌)与 IEC 61000-4-2(静电放电)
  • RoHS 合规
  • 封装:SOD-323(小尺寸,适合空间受限设计)

二、电气参数(关键)

  • Vrwm(反向稳态电压):5V
  • VBR(击穿电压):8V(按厂商标注)
  • 钳位电压:约 20V(在 8/20μs、Ipp 条件下测得)
  • Ipp(8/20μs 峰值电流):18A
  • Ppp(8/20μs 峰值功率):360W
  • Ir(漏电流):1μA(典型,低功耗系统友好)
  • Cj(结电容):0.6pF(适合高速数据/信号线)

三、保护性能解读

  • 瞬态吸收能力:在行业标准 8/20μs 浪涌波形下,器件能吸收 360W 峰值功率,对短时的大能量浪涌(如瞬时雷击或电源开关瞬变)提供有效钳位与吸收;
  • ESD 抑制:对 IEC 61000-4-2 静电放电事件有良好响应,能够快速将高幅度短持续时间脉冲钳位到安全电平,保护后端敏感器件;
  • 低电容优势:0.6pF 的低结电容使其对高速数据信号(USB、串行接口、传感器数据线等)干扰小,适合对信号完整性要求高的接口;
  • 双向结构:可在正负电压瞬态下对称工作,适合带交流分量或双向数据传输的 I/O 线保护。

四、封装与机械特性

  • 封装类型:SOD-323,体积小,适合表面贴装(SMT)工艺;
  • 空间优点:适用于手机主板、配件 PCB、便携式设备中占位严格的保护点;
  • 焊接兼容性:符合常见回流焊工艺(请参考供应商焊接曲线与储存说明以避免过热损伤)。

五、典型应用场景

  • 手机及移动终端 I/O 线、按键与触摸接口保护;
  • 耳机、充电器、数据线等移动配件的接口保护;
  • 基于微处理器(MCU/SoC)的外部通讯口(如 UART、I2C、SPI、单端数据线)保护;
  • 便携设备中对抗 ESD、EMP、开关瞬变与短时浪涌的防护点。

六、应用建议与布局注意事项

  • 布局位置:将 FSJEB05C 靠近被保护的连接器或 ESD 源(比如外部插口)放置,以缩短到 PCB 地/信号回路的路径,减少感性/电阻性寄生;
  • 接地安排:确保保护器的地线有低阻抗、短路径接到系统地;在差分或屏蔽设计中,根据信号拓扑选择合适的接地方式;
  • 串联元件:在需要时可与小串联阻抗或共模滤波器配合使用,以改善系统的总体 EMI/ESD 耐受性和滤波性能;
  • 温度与功率:注意器件在高能脉冲后的热量分布与 PCB 热管理;频繁高能脉冲可能需要评估器件寿命与可靠性。

七、合规性与可靠性

  • 满足 IEC 61000-4-5 和 IEC 61000-4-2 标准,适用于有抗浪涌与抗静电要求的消费电子产品;
  • RoHS 合规,便于整机环保认证与量产应用。

八、订购信息与包装

  • 品牌:FUXINSEMI(富芯森美)
  • 型号示例:FSJEB05C(SOD-323 封装)
  • 在订购时请注明封装与交货形式(卷盘或托盘),并向供应商索取完整数据手册、回流焊接规范及可靠性测试报告以便工程验证。

总结:FSJEB05C 通过 360W(8/20μs)的大能量吸收能力、低泄漏与极低结电容特性,针对 5V 工作电压的单路双向 I/O 保护提供了性能与体积的良好平衡,适合移动终端及微处理器外围的 ESD/浪涌防护需求。建议在设计初期纳入保护元件验证,并按实际系统条件做 PCB 布局与热/电评估。

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
