PESDREC2XD5VBF 产品概述

一、产品简介

PESDREC2XD5VBF(品牌:Prisemi/芯导)是一款面向高速信号线的超低电容静电放电(ESD)保护器件,采用 DFN0603-2L 小型封装,专为对信号完整性要求高的应用场景设计。器件为双向结构,工作电压 Vrwm = 5V,具有极低的结电容(Cj = 0.15 pF),在保护敏感半导体元件免受静电或其它瞬态过电压冲击时,能最大限度地保持高速接口的传输性能。

二、主要特性

  • 极性:双向,适用于双向信号线和差分对保护。
  • 工作电压(Vrwm):5 V,适配常见 5V 或低电压逻辑接口。
  • 钳位电压:7.5 V(典型),在能量吸收时保持较低的钳位水平,降低被保护器件应力。
  • 击穿电压(VBR):9 V(典型),在超过 Vrwm 时进入雪崩导通,吸收瞬态能量。
  • 峰值脉冲电流(Ipp):4 A @ 8/20 µs,支持板级常见脉冲能量。
  • 峰值脉冲功率(Ppp):30 W @ 8/20 µs。
  • 反向漏电流(Ir):1 µA(典型),保证正常工作时低漏电损耗。
  • 结电容(Cj):0.15 pF,极低电容对高速信号影响极小。
  • 工作温度范围:-55 ℃ ~ +150 ℃,适应工业级温度环境。
  • 防护等级:符合 IEC 61000-4-5(雷电浪涌)与 IEC 61000-4-2(静电放电)标准要求。
  • 封装:DFN0603-2L,体积小,便于 PCB 布局与空间受限的产品设计。

三、性能优势

  • 极低寄生电容:0.15 pF 的结电容使其对高速数据线(如 USB、HDMI、MIPI、LVDS 等)几乎无可感知的影响,保证信号眼图和上升/下降时间。
  • 快速响应:瞬态事件触发器件进入雪崩导通,能迅速钳位高电压,保护下游芯片。
  • 大截面积结结构:支撑更高的瞬态电流承受能力(Ipp 4A),适合板级防护需求。
  • 小体积封装:DFN0603-2L 有利于高密度布板及贴片生产工艺。

四、典型应用场景

  • 智能手机摄像头接口、MIPI 信号保护
  • USB/USB-C、HDMI、DisplayPort 等高速数据接口
  • 网络通信模块、高速差分总线(例如 LVDS)
  • 工业控制、仪器仪表的低电容信号保护
  • PCB 板级入口处的 ESD/浪涌防护

五、封装与可靠性

  • 封装形式:DFN0603-2L 小型贴片封装,适用于自动贴装与回流焊工艺。
  • 工作温度:-55 ℃ ~ +150 ℃,满足大多数工业和商用环境的可靠性要求。
  • 通过 IEC 61000-4-2 与 IEC 61000-4-5 等电磁兼容(EMC)规范验证,适合需要合规防护的产品设计。

六、应用与布局建议

  • 放置位置:将器件尽量靠近外部接口或连接器端放置,以缩短受到的传输路径与寄生电感,从而提高防护效果。
  • 腔地与接地:器件的接地面应通过多颗过孔连到主地平面,保证瞬态电流能迅速分散到地;避免地回路阻抗过大。
  • 串联元件:在极端场景下,可与小阻值系列电阻或共模滤波器配合使用,以进一步降低传导性干扰和峰值能量。
  • 焊接工艺:按照常规回流焊工艺进行,注意焊盘焊膏用量和回流曲线,以确保焊点可靠性。

七、选型与注意事项

  • 与被保护器件耐压匹配:Vrwm = 5V 时适合保护 5V 或更低电压接口,若需保护更高工作电压线路,应选用对应 Vrwm 更高的型号。
  • 能量评估:PESDREC2XD5VBF 针对板级 ESD 和一般浪涌事件设计,不能替代供电侧或高能量雷击防护器件;在高能量应用(如直击雷/建筑级防雷)应结合更大能量吸收元件。
  • 频带宽度考虑:超低 Cj 适合高带宽,仍需综合 PCB 布局、阻抗匹配等因素确保系统性能。
  • 反向漏电:Ir 典型为 1 µA,在一些超低功耗待机设计中应考虑其对整体漏电预算的影响。

PESDREC2XD5VBF 以其超低电容、小巧封装与良好瞬态吸收能力,为对信号完整性要求高的现代电子产品提供了一种兼顾保护与性能的板级 ESD 解决方案。若需进一步的电气参数曲线、封装图或参考电路图,请查阅厂商数据手册或联系技术支持获取完整版资料。

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.
