PESD2CAN 产品概述

一、产品简介

PESD2CAN 是 Leiditech(雷卯电子)出品的一款双路双向瞬态抑制器(TVS),专为 CAN 总线及类似差分信号线的静电放电与浪涌保护设计。器件采用 SOT-23 封装,体积小、易于贴装,适合集成于车载与工业接口防护电路中。

二、主要特性

  • 钳位电压(Vc):58V(典型峰值钳位)
  • 击穿电压(Vbr):28.5V
  • 反向截止电压(Vrwm):24V(适配 12V/24V 系统)
  • 峰值脉冲功率:420W @ 8/20µs
  • 峰值脉冲电流:9A @ 8/20µs
  • 反向漏电流(Ir):500nA(典型,小泄漏)
  • 结电容(Cj):30pF(单通道)
  • 通道数:双路,极性:双向
  • 符合标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)

三、应用场景

适用于 CAN 总线收发器、车载通讯接口、工业现场总线、监控设备与各类需要防护差分信号线的场合。针对 12V/24V 工作环境及常见静电、感性负载回路产生的瞬态干扰提供有效钳位与吸收能力。

四、电气特性与设计要点

器件 Vrwm 24V,建议用于最大工作电压不超过 24V 的总线侧;Vbr 28.5V 表明在高于工作电压时进入击穿导通;Vc 58V 可在大冲击电流下将瞬态钳制到安全水平。30pF 的结电容对高速信号有一定影响,设计时需评估对 CAN-FD 等高频模式的影响。

五、布局与使用建议

  • 器件应尽量靠近接口或受保护器件放置,缩短走线,减小回路感抗;
  • 共地布线应低阻、短路径,避免环路回路;
  • 若系统对总线电容敏感,可在设计中进行仿真或加短路电容补偿;
  • 推荐与常规保护电路(共模电感、差模电阻等)配合使用以增强抗扰能力。

六、封装与可靠性

SOT-23 小体积封装便于自动贴装与批量生产,适合工业与车载环境的布局密度要求。器件符合 IEC 61000-4-2/4-4/4-5 标准,可满足一般现场与装置级的瞬态防护需求。

七、选型注意事项

选型时关注系统最大工作电压与允许钳位电压,评估结电容对信号完整性的影响,确认峰值脉冲能力满足可能的冲击情形。双路双向结构适合保护 CAN_H/CAN_L 两线,替代两个单通道器件时可节省 PCB 面积与成本。

八、总结

PESD2CAN 以其高达 420W 的吸收能力、9A 的峰值冲击电流、低漏电与双路双向结构,为 CAN 总线及差分信号线提供紧凑而可靠的瞬态保护方案,适合车载与工业环境的稳健设计需求。若需样片或详细数据手册,可联系 Leiditech(雷卯电子)获取完整器件特性与应用指导。

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
