BDFN2C361V35 产品概述

一、产品简介

BDFN2C361V35 是 BORN(伯恩半导体)推出的一款双向瞬态电压抑制(TVS)二极管,采用 DFN1006-2(0402 等效)超小封装。器件为单路双向保护,设计用于抑制瞬态过压与脉冲干扰,保护敏感电子器件免受雷击、开关瞬变和静电放电(ESD)损伤。

二、主要电气参数

  • 极性:双向
  • 工作反向截止电压 Vrwm:36 V
  • 击穿电压 Vbr(典型):40 V
  • 钳位电压 Vc:70 V(典型)
  • 峰值脉冲电流 Ipp:4 A(8/20 μs 标称);部分资料标注 5 A,实际能力请以厂家数据手册和应用条件为准
  • 峰值脉冲功率 Ppp:450 W(8/20 μs)
  • 反向漏电流 Ir:500 nA(典型)
  • 结电容 Cj:13 pF(影响高速信号完整性)
  • 通道数:单路
  • 防护等级/认证:符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 标准要求

三、特性亮点

  • 超小 DFN1006-2(0402 等效)封装,便于高密度 PCB 布局与便携式终端应用。
  • 双向结构,适用于差分信号线或需对称保护的线路(例如交流或双向数据线)。
  • 低漏电流与适中结电容,在保持低静态功耗同时兼顾对中低速信号的兼容性。
  • 通过多项工业级瞬态与静电抗扰度标准,可靠性高,适合恶劣电磁环境。

四、典型应用场景

  • USB/串行通讯接口、差分信号线保护(视速率与结电容限定)
  • 电源线与电池保护(反向/浪涌抑制)
  • 工业控制接口、继电器驱动线路的瞬态保护
  • 消费电子、便携设备、车载电子辅助防护(需验证车规要求)

五、封装与布局建议

  • 封装:DFN1006-2(尺寸接近 0402),焊盘极小,要求精确的 PCB 制造与贴装工艺。
  • 布局建议:将 TVS 器件置于需保护节点的尽量靠近处,最短走线到被保护端;与接地平面间保持良好焊接和散热路径。
  • 对高速差分线应注意结电容(13 pF)对信号眼图的影响,必要时选择更低电容器件或在前端增加匹配网络。

六、选型与设计注意事项

  • 确认最大持续工作电压与系统工作电压匹配(Vrwm 36 V)。
  • 钳位电压 70 V 表明在强冲击下仍有较高剩余电压,需评估后级器件耐压能力。
  • 峰值脉冲能力与能量吸收依赖脉冲波形(8/20 μs),若遇到更长/更复杂的浪涌,应参考能量降额或并联更大能量器件。
  • 结电容 13 pF 可能影响高频/高速应用,数据线高于数百 Mbps 时需谨慎验证信号完整性。

七、可靠性与包装

  • 器件符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)和 IEC 61000-4-5(浪涌)等标准测试等级,适合工业与消费级抗扰度设计。
  • 建议按厂家推荐的回流焊曲线与储存条件操作,避免超出温度与湿度限制导致焊接缺陷或性能退化。

总结:BDFN2C361V35 为一款适合中电压侧、空间受限场合的双向 TVS 器件,兼顾体积与防护能力。在实际设计中应结合实际浪涌能量、后端耐压及信号速率评估其适用性,并严格按封装与焊接规范进行布局与工艺控制。如需最终确认参数或样品测试结果,请参阅厂商完整版数据手册或联系供应商获取验证资料。

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
