PESD3V3V1BCSF-N 产品概述

一、产品简介

PESD3V3V1BCSF-N 是 BORN(伯恩半导体)推出的一款微型双向瞬态抑制(TVS)二极管,采用固态硅雪崩技术,封装为超小型 DFN0603,专为便携设备和基于微处理器的系统提供静电和浪涌保护。该器件具有低钳位、低泄漏和较高峰值脉冲能量,适合在空间受限且对电源/信号完整性有要求的场合使用。

二、主要参数一览

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:3.3 V
  • 击穿电压 VBR:3.4 V
  • 钳位电压(典型):13 V
  • 峰值脉冲电流 Ipp:9 A
  • 峰值脉冲功率 Ppp:70 W(8/20 μs)
  • 反向电流 Ir:200 nA(在 Vrwm 下)
  • 结电容 Cj:17 pF
  • 防护等级:满足 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5
  • 类型:ESD 保护(双向)
  • 封装:DFN0603(微型)

三、关键特性与优势

  • 低钳位电压:在脉冲事件中将电压限制在较低水平,最大限度保护下游芯片免受过压应力。
  • 高瞬态能力:70 W(8/20 μs)峰值脉冲功率与 9 A 峰值脉冲电流,能吸收常见的浪涌与击穿事件(如插拔、充电器浪涌等)。
  • 低泄漏:200 nA 的低泄漏电流有利于电池供电系统,减少待机损耗。
  • 微型封装:DFN0603 占板面积小,适合手机、耳机、可穿戴及其它空间受限的模块。
  • 双向配置:可保护可能出现正/负极性瞬变的信号或线路(例如差分接口或可能反向施加电压的场景)。

四、典型应用场景

  • 手机及配件:充电口、耳机接口、按键/触摸接口等。
  • 基于微处理器的设备:GPIO、I2C、UART 等 3.3 V 逻辑线防护(注意结电容对高速信号的影响)。
  • 接口防护:对抗静电放电(ESD)、电快速瞬变(EFT)及浪涌事件的保护方案。

五、设计与布局建议

  • 尽量将器件靠近被保护的端口或 IC 引脚放置,缩短走线,减小回路面积以提高抑制效果。
  • 对于需要承受高能量的场合,可在器件底部或附近设计合适的地铜和热通孔以增强散热与功率承受能力。
  • 由于结电容为 17 pF,器件适合低速及中速信号线;对超高速接口(如 USB2.0/USB3.0 高速通道)建议评估信号完整性,必要时选择更低电容的 TVS 器件。
  • 双向器件无需极性区分,但需保证良好接地以发挥最大保护性能。

六、可靠性与合规

PESD3V3V1BCSF-N 满足 IEC 61000-4 系列(-2、-4、-5)测试要求,体现其对静电、快速瞬变及浪涌的防护能力。器件采用硅雪崩工艺,稳定性高,适合消费类及工业类短时冲击防护应用。

总结:PESD3V3V1BCSF-N 在极小封装下提供高能量吸收、低漏电和低钳位电压,是对 3.3 V 类信号线路进行空间受限防护的理想选择。但在选型时应结合目标接口速率与结电容影响,完成必要的 EMC/信号完整性验证。

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
