ESD9B5VL — 静电与浪涌保护二极管(TVS/ESD)

一、产品简介

ESD9B5VL 是台舟电子(TECH PUBLIC)推出的一款小型双向瞬态电压抑制器,专为对抗静电放电(ESD)和雷击/浪涌(Surge)冲击而设计。器件封装为 DFN1006-2,单路、双向极性,适用于空间受限且对信号完整性要求较高的应用场景,可在工业级温度范围内稳定工作(-55℃ ~ +125℃)。

二、主要电气参数

  • 钳位电压(Vc,典型):12 V
  • 反向稳态电压(Vrwm):5 V
  • 击穿电压(Vbr):8.4 V
  • 峰值脉冲功率:35 W @ 8/20 μs
  • 峰值脉冲电流(Ipp):3 A @ 8/20 μs
  • 反向漏电流(Ir):80 nA(常温)
  • 结电容(Cj):约 5 pF
  • 通道数:单路;极性:双向
  • 工作温度:-55 ℃ ~ +125 ℃
  • 防护等级:符合 IEC 61000-4-5(浪涌)与 IEC 61000-4-2(ESD)

三、特性与优势

  • 低钳位电压(12 V),在冲击事件中能有效限制线路电压,保护下游器件。
  • 低结电容(5 pF),对高速、差分或敏感模拟信号线几乎无可感知的影响,适合高速接口保护。
  • 双向结构适用于信号可正负摆动的场合(如差分对、通讯口),无需考虑极性方向。
  • 支持 IEC 标准的 ESD 与浪涌试验,可靠性高,适合工业与商用环境使用。
  • DFN1006-2 超小封装,便于密集板级集成与成本优化。

四、典型应用场景

  • 5 V 供电和信号系统的端口保护(USB、GPIO、电源线等)
  • 高速数据线与差分接口(当信号幅值范围在 Vrwm 附近或可双向摆动时)
  • 工业控制、仪表、POS、通讯设备、便携电子产品的外部接口防护
  • 需要低电容且对板面空间敏感的应用,如摄像头接口、触控接口等

五、布局与使用建议

  • 器件应尽量靠近受保护的连接器或外部接口放置,以缩短未保护引线长度,减少寄生感抗和回路面积。
  • 对于双向 TVS,输入与被保护线对称连接,确保信号路径连续且阻抗匹配。
  • 在高速差分线保护时,保持 TVS 与线间的最短走线,并避免形成环路。
  • DFN1006-2 焊盘设计应参考制造商推荐的焊盘尺寸并注意回流焊工艺控制,确保焊点可靠性。

六、可靠性与选型注意事项

  • 器件在规定的功率脉冲(8/20 μs)条件下能承受 35 W 峰值功率,峰值电流 3 A。选择时应评估系统遭遇的大电流/大能量事件频率及能量水平。
  • 反向漏电流 80 nA 表明在静态工作点上对电路漏电影响极小,但在超低功耗设计中仍需评估整体漏电预算。
  • 若需更高能量承受能力或特定汽车级认证,请核对是否满足额外的规范或选用更高等级产品。

ESD9B5VL 以其小型化、低电容与符合 IEC 标准的防护性能,为 5 V 及高速信号系统提供高效的板级静电与浪涌防护方案。采购或设计集成时,请参照台舟电子(TECH PUBLIC)提供的详细数据手册与封装推荐焊盘以获得最佳性能。

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
