PESD2CAN 产品概述

一、产品简介

PESD2CAN 是华轩阳电子(HXY MOSFET)推出的双路双向瞬态电压抑制器,封装为 SOT-23,专为 CAN 总线及其他差分数据线提供快速、低电容的静电放电(ESD)和浪涌保护。器件在24V 工作电压下保持低漏电和快速钳位响应,适用于工业与车载通信接口的过压防护需求。

二、主要参数概览

  • 极性:双向
  • 反向截止电压 Vrwm:24V
  • 钳位电压 Vclamp:40V(典型)
  • 峰值脉冲电流 Ipp:4A(8/20µs 波形)
  • 峰值脉冲功率 Ppp:160W@8/20µs
  • 击穿电压 Vbr:33V
  • 反向电流 Ir:500nA(典型)
  • 通道数:双路
  • 结电容 Cj:10pF(典型)
  • 防护等级:符合 IEC 61000-4-2 标准
  • 封装:SOT-23
  • 类型:ESD,型号:PESD2CAN(华轩阳电子)

三、产品特性与优势

  • 双向保护:支持信号正负摆幅,适配差分总线(如 CAN)无需方向约束。
  • 低结电容(10pF):对高速数据传输影响小,保持信号完整性,适合 CAN-FD 与高速通讯场景。
  • 高能量吸收能力:160W(8/20µs)功率等级与 4A 峰值脉冲电流,能有效吸收瞬态冲击与静电放电能量。
  • 低漏电:Ir 仅 500nA,可在低功耗系统中使用,避免对信号偏置产生干扰。
  • 紧凑封装:SOT-23 小体积,便于靠近接口放置,优化 PCB 布局与抑制传导干扰。

四、典型应用场景

  • 汽车与商用车 CAN 总线端口保护(12V/24V 系统兼容)
  • 工业现场总线、楼宇自控中的差分数据线保护
  • 通信接口、传感器信号线、I/O 端口的防护与浪涌抑制
  • 需要 IEC 61000-4-2 ESD 抗扰能力的连接器与外部接口

五、使用建议与 PCB 布局要点

  • 器件应尽量靠近外部连接器或受保护端口放置,缩短信号到器件的走线长度以降低感性耦合。
  • 将器件的公共参考(通常为地)通过低阻抗回流路径连接至系统地平面,使用短、粗的走线或过孔确保快速放电回路。
  • 对于高频或差分信号,注意控制走线阻抗与对称性,避免器件并联或过度去耦以免影响信号质量。
  • 在严苛环境下结合适当的熔断保护或滤波元件(如共模电感、串联电阻)实现多级防护。

六、封装与引脚说明

PESD2CAN 采用 SOT-23 小封装,典型布局为两个受保护信号引脚与一个公共参考引脚(地)。具体引脚编号与封装建议以厂商数据手册为准,选型与 PCB 设计时请参考华轩阳提供的完整版资料。

七、选型提示

  • 若系统工作电压或浪涌要求高于 24V 或更大能量吸收,请选择额定电压与功率更高的 TVS 产品;
  • 在高速或高带宽应用中,优先考虑低结电容(Cj)规格以降低对信号的影响;
  • 如需更严格的汽车级可靠性认证(如 AEC-Q100),请向供应商确认产品认证状态与可用版本。

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
