BNPESD5V0S1UL 产品概述

BNPESD5V0S1UL 是 BORN(伯恩半导体)推出的一款单向 TVS 二极管,专为 5V 工作电压系统的静电放电(ESD)、电快速瞬变(EFT)和浪涌(Surge)保护而设计。器件采用超小封装(0402 / DFN1006-2 / SOD-882),在空间受限的消费电子、移动设备与接口保护场景中,能够在保持较低结电容的同时提供可靠的瞬态抑制能力。

一、主要规格与性能特点

  • 极性:单向(针对正向瞬态钳位)
  • 反向稳压 Vrwm:5 V(推荐在 5V 系统中作为工作电压点)
  • 击穿电压 VBR:典型 7.2 V(器件进入钳位前的击穿点)
  • 钳位电压 Vcl:10 V(Ipp=7 A @ 8/20µs 条件下典型值)
  • 峰值脉冲电流 Ipp:7 A @ 8/20µs
  • 峰值脉冲功率 Ppp:70 W @ 8/20µs
  • 反向漏电流 Ir:100 nA(在 Vrwm 条件下低漏电,适合低功耗系统)
  • 结电容 Cj:50 pF(典型值,适用于中速至一般高速信号线)
  • 通道数:单路
  • 防护等级 / 认证:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)相关要求
  • 封装:DFN1006-2 (SOD-882),俗称 0402 超小型贴片封装

二、核心优势

  • 小尺寸封装:0402/DFN1006-2 大幅降低 PCB 占用面积,利于紧凑型设计与盲伏置放。
  • 低漏电与稳定钳位:100 nA 的低反向电流有利于电池供电与低功耗设备;10 V 的典型钳位电压可在 5 V 系统保护下提供有效抑制。
  • 高冲击承受能力:7 A 脉冲电流与 70 W 脉冲功率能力能够应对常见的操作性静电与工业脉冲事件。
  • 符合工业级防护标准:满足 IEC 61000 系列测试,方便通过系统级 EMC 认证。

三、典型应用场景

  • USB(包括 USB2.0/3.0)、HDMI、DisplayPort 等接口保护(连接器端口靠近放置)
  • 智能手机、平板、可穿戴设备的 I/O 接口与数据线保护
  • 工业控制器和物联网终端的信号线、防护端口
  • 摄像头模块、传感器接口及其他需要 5V 工作电压保护的电子模块

四、布局与使用建议

  • 放置位置:将 TVS 器件尽量靠近受保护的接口或连接点,以缩短走线并提高防护效率。
  • 接地处理:器件的地端应做可靠的低阻抗接地,若为多层板建议在器件周围加铺地铜并使用多个过孔与地相连。
  • 走线要求:保护线与地之间的走线越短越好,避免环路面积,降低感性耦合带来的二次干扰。
  • 对于高速信号:由于本器件结电容约 50 pF,可能对高频信号(如高速 USB/HDMI)产生一定影响,需在系统级测试中验证是否满足信号完整性要求;对超高速接口可考虑更低 Cj 的 TVS 器件或并联阻容补偿方案。
  • 温度与焊接:器件为小型贴装封装,建议按制造商提供的回流焊工艺曲线进行组装;若对湿敏等级(MSL)有要求,请参照详细数据手册执行烘干/再流前处理。

五、选型注意事项

  • 若系统直流工作电压高于 5 V,应选择 Vrwm 更高的型号以避免误触发。
  • 对于需要更低钳位或更高脉冲能量的场合,请参考符合更高功率等级或多通道并联的 TVS 产品。
  • 在信号完整性要求严格的场景中,评估结电容对上升沿、时延和阻抗匹配的影响,必要时在原型机上进行信号测试。

BNPESD5V0S1UL 以其超小封装、良好的钳位性能与工业级防护认证,适合应用在对尺寸敏感且需要可靠瞬态抑制的 5V 系统。欲获取详细电气特性曲线、回流焊工艺与可靠性数据,请参阅官方技术数据手册或联系伯恩半导体授权分销商。

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
