ES D2CAN24-ES 产品概述

一、产品简介

ESD2CAN24-ES 是静芯微(ElecSuper)推出的一款面向 CAN/差分总线保护的双路双向瞬态电压抑制器(TVS)。器件封装为 SOT-23,适合空间受限的汽车和工业电子应用。产品主要用于抑制静电放电(ESD)、浪涌和线路瞬态,保护 CAN 收发器和接口电路免受过压损坏。

二、关键规格一览

  • 极性:双向(适合双向瞬态)
  • 通道数:双路
  • 反向截止电压 Vrwm:24 V
  • 击穿电压:28 V
  • 钳位电压 Vcl:42 V(典型)
  • 峰值脉冲电流 Ipp:8 A @ 8/20 µs
  • 峰值脉冲功率 Ppp:340 W @ 8/20 µs
  • 反向电流 Ir:100 nA(常温)
  • 结电容 Cj:18 pF(每通道典型值)
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 防护等级/标准:符合 IEC 61000-4-2(ESD)
  • 封装:SOT-23
  • 品牌:ElecSuper(静芯微)

三、主要特性与优势

  • 双路设计:在单个 SOT-23 封装内集成两路保护器件,节省 PCB 面积,便于对 CAN_H 和 CAN_L 或两路信号线并行保护。
  • 双向钳位:对正/负极性瞬态均能有效钳位,适合差分总线与双向数据传输环境。
  • 高脉冲能力:8 A 峰值脉冲电流与 340 W 的 8/20 µs 峰值功率能力,可承受常见供电浪涌和雷击诱发瞬态。
  • 低漏电流:100 nA 的反向电流可满足严苛的待机与低功耗系统要求。
  • 低结电容:约 18 pF 的结电容有助于减小对高速差分信号的影响,保持信号完整性,尤其适合 CAN 等中低速总线系统。
  • 宽温度范围:-40 ℃ 至 +125 ℃,满足汽车级与工业级环境可靠性需求。

四、典型应用场景

  • 汽车 CAN 总线接口与收发器保护(车载通信、ECU、车身控制)
  • 工业现场总线(如现场控制器、数据采集模块)
  • 车载 OBD、网关与车载以太网(可用于类似差分信号的保护)
  • 智能交通终端、仪表盘与车载信息娱乐系统的接口防护
  • 其他需抗 ESD、浪涌或线缆耦合瞬态的差分信号线路

五、典型接法与 PCB 布局建议

  • 接法建议:将每一路 TVS 分别连接在 CAN_H 与 GND、CAN_L 与 GND;也可根据系统需求在差分对之间并联差分 TVS 以增强共模抑制。由于器件为双向型,适合直接并联于信号线与地之间。
  • 布局要点:
    • TVS 元件应尽量靠近信号输入连接器或电缆入口放置,以缩短受保护路径长度。
    • 使用宽地铜箔或多层接地平面以便迅速分散能量,尽量减少地回路电阻和感抗。
    • 避免在 TVS 与被保护器件之间使用长走线或多余的走线环路,减少串联电感和寄生阻抗。
    • 对于高速信号场合,注意保持差分阻抗一致,尽量减少 TVS 的并联电容对信号质量的影响(18 pF 是常见平衡值,但仍需在实际系统中评估)。

六、可靠性与合规性

  • ESD 防护:产品符合 IEC 61000-4-2 标准的 ESD 抗扰度要求,可有效应对人体模型和接触/空气放电形式的静电冲击(具体抗等级请参照产品数据手册)。
  • 温度与寿命:支持 -40 ℃ 至 +125 ℃ 的工作温度,可用于汽车与工业级长期运行环境。
  • 表面贴装封装(SOT-23)适合自动化贴装与回流焊,便于生产和一致性保证。

七、选型与使用注意

  • 在选型时确认系统的最大工作电压是否低于 Vrwm(24 V),以保证在正常工作下 TVS 不导通。
  • 钳位电压 42 V 为瞬态下限制电压的典型值,针对敏感器件应评估是否足够低以防损坏。
  • 对于要求极低电容的高速接口,应评估 18 pF 电容对信号眼图和链路性能的影响。
  • 请参考 ElecSuper 的完整数据手册获取精确的 I-V 曲线、峰值能量测试条件、封装尺寸及焊接规范。

八、封装与订购信息

  • 封装:SOT-23,适合表面贴装(SMT)工艺。
  • 型号:ESD2CAN24-ES,品牌 ElecSuper(静芯微)。
  • 订购时请参照供应商提供的包装单位(卷盘、散装等)与批次信息,并索取最新的数据手册以便完成最终设计验证。

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.
