PESD5V0F1BSF-N 产品概述

一、产品简介

PESD5V0F1BSF-N 是 BORN(伯恩半导体)推出的一款双向(Bipolar)瞬态电压抑制器(TVS/ESD保护器),专为 5V 体系与高速接口的静电放电(ESD)和脉冲浪涌(Surge)保护而设计。器件采用小型 DFN0603 封装,单通道结构,具备极低结电容,适合对信号完整性要求高的接口保护应用。

二、主要参数

  • 极性:双向(Bipolar)
  • 反向截止电压 Vrwm:5 V(适用于 5V 工作电压系统)
  • 击穿电压 VBR:8.5 V
  • 钳位电压(典型):25 V
  • 峰值脉冲电流 Ipp:3 A @ 8/20 μs
  • 峰值脉冲功率 Ppp:60 W @ 8/20 μs
  • 反向漏电流 Ir:100 nA
  • 结电容 Cj:0.2 pF(低电容)
  • 通道数:单路
  • 防护等级:符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 标准
  • 封装:DFN0603(表面贴装)
  • 类型:ESD 抑制器
  • 品牌:BORN(伯恩半导体)

三、核心优势与特性

  • 低结电容(0.2 pF):非常适合高速信号线(如 USB、TTL 等)或差分对的保护,可最大限度降低对信号带宽和上升时间的影响。
  • 双向结构:可在信号正负方向上对称钳位,适用于可出现正负瞬态的信号线或双极性接口。
  • 低漏电(100 nA):适合电池供电和低功耗设备,减少静态电流对系统功耗的影响。
  • 小封装(DFN0603):占板面积小,利于移动设备、可穿戴设备和紧凑型电子产品的空间优化。
  • 抗干扰合规:满足 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT/脉冲)和 IEC 61000-4-5(浪涌)标准,适合工业及消费类环境的电磁兼容(EMC)防护需求。
  • 中等能量承受能力:Ipp=3A(8/20 μs)与 Ppp=60W 的组合可应对常见的静电放电与短时浪涌事件。

四、典型应用场景

  • USB、GPIO、UART、I2C 等 5V 或接近 5V 的信号接口保护
  • 高速数据线与射频前端的输入防护(因低电容适合高速信号)
  • 移动终端、可穿戴设备和 IoT 终端的外部接口防护
  • 工业控制与测量设备的信号端口防护(满足 IEC 相应抗干扰标准)
  • 电源浪涌与瞬态抑制(适用于小功率的局部浪涌防护)

五、应用与布局建议

  • 元件应尽量靠近被保护的连接器或接口放置,确保走线最短、寄生感抗最小,从而提高保护效率。
  • 对于单端信号,器件通常直接并联在信号线与地之间;双向器件在正负瞬态时均能对称钳位,适合无方向性的接口。
  • 若保护的是差分对,应在每个通道上各放置一只,或按系统需求选择相应的差分方案。
  • 在需要承受较大浪涌能量的应用中,建议与串联阻抗(如小电阻或共模电感)配合使用,以分担能量并降低钳位电压对下游器件的冲击。
  • 注意焊盘与散热垫的焊接质量,DFN0603 小封装需保证良好焊接以利于热量与能量的快速扩散,降低重复脉冲下的损伤风险。

六、可靠性与使用注意

  • 器件的钳位电压约为 25V(典型),在选择被保护器件时需保证下游器件能承受钳位电压短时冲击或通过外部限流手段降低到安全范围。
  • 虽具备 IEC 相关标准防护能力,但在频繁或高能量冲击环境下器件寿命会下降,建议在系统设计中评估并留有余量。
  • 按照常规 SMT 回流焊工艺进行焊接,遵循制造商的回流温度曲线与湿度控制建议(若需要更严格的焊接工艺参数,请向 BORN 获取详细资料)。
  • 储存与运输过程中避免静电与机械应力,开卷贴片设备时遵循防静电操作规程。

七、采购与替代建议

PESD5V0F1BSF-N 属于单路低电容双向 TVS 解决方案,适合多数 5V 接口防护需求。如需更高浪涌能量或多路集成封装,可向供应商咨询同系列的高能量型号或多通道封装版本。采购时请确认包装形式(卷带数量)、版本号与质量认证,以满足工程量产与可靠性要求。

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
