PESD2CAN — 高速差分总线用双向ESD保护器件(SOT-23)

一、概述

PESD2CAN 是 GOODWORK(固得沃克)推出的单路双向ESD保护器件,专为高速数据传输接口(如CAN总线、差分信号线等)设计。器件在保证对瞬态静电放电的高效钳位能力同时,保持较低结电容(Cj = 25 pF),最大限度降低对信号完整性的影响,是高集成度汽车电子、工业控制与通信设备的理想选择。

二、主要性能特点

  • 双向设计,适用于差分信号保护(CAN_H ↔ CAN_L);
  • 反向截止电压(Vrwm):24 V,适配车载及工业电压等级;
  • 击穿电压(VBR):30.2 V,钳位电压典型值 50 V,在瞬态时提供有效钳位;
  • 峰值脉冲电流 Ipp:7 A,峰值脉冲功率 Ppp:350 W(在标准脉冲条件下);
  • 低反向电流 Ir:100 nA(微安级漏电,提升系统稳定性);
  • 低结电容 Cj:25 pF,有利于保持高速差分信号的带宽与时序完整性;
  • 工作温度范围宽:-55 ℃ 至 +150 ℃,适应严苛环境;
  • 符合 IEC 61000-4-2 静电放电防护等级要求;
  • 封装:SOT-23,体积小,便于贴片安装与自动化生产。

三、关键电气参数(要点)

  • 类型:ESD,双向;
  • 通道数:单路;
  • Vrwm:24 V;
  • VBR:30.2 V;
  • 钳位电压:50 V(典型);
  • 峰值脉冲电流 Ipp:7 A;
  • 峰值脉冲功率 Ppp:350 W(标准脉冲条件);
  • 反向电流 Ir:100 nA;
  • 结电容 Cj:25 pF;
  • 工作温度:-55 ℃ ~ +150 ℃;
  • 包装:SOT-23。

四、典型应用场景

  • 汽车CAN总线与车载网络接口(车载控制器、网关、传感器节点);
  • 工业总线与现场总线接口(长线、易受静电影响场合);
  • 差分高速数据接口保护(需低电容的现场设备或主板端);
  • 移动终端、通信设备与各种需要ESD防护的外设接口。

五、PCB布局与使用建议

  • 器件应尽量靠近外部连接器或信号入口处放置,以缩短非受保护走线长度;
  • 对差分信号推荐将 PESD2CAN 直接连接于 CAN_H 与 CAN_L 之间(双向钳位),必要时可配合到地的单向TVS提供额外保护;
  • 保持走线短且粗,减小串扰与寄生电感,避免在器件周围形成回流环路;
  • 对高速信号注意差分对的长度与阻抗匹配,器件低结电容有助于降低对信号的影响。

六、封装与可靠性

PESD2CAN 以 SOT-23 小外形封装提供,便于自动贴装和批量生产。器件适用于工业与汽车温度等级(-55 ℃~+150 ℃),在典型ESD脉冲条件下表现出稳定的钳位能力与可重复防护能力。符合 IEC 61000-4-2 标准的静电防护要求,满足多数商业与工业应用的抗干扰水平。

七、选型与建议

在选型时,如果目标系统对信号带宽与抖动敏感,应关注结电容(Cj = 25 pF)对链路的影响;若系统需更高的脉冲电流或更低钳位,考虑并联或选用更高功率等级的TVS器件。PESD2CAN 适合用于需要紧凑封装与可靠ESD防护的设计场景,品牌:GOODWORK,封装:SOT-23,便于直接替换或集成到现有设计中。

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
