ESD2CANFD24DBZR 双路ESD保护二极管产品概述

ESD2CANFD24DBZR是德州仪器(TI)推出的双路双向ESD保护二极管,专为高速信号线路(尤其是CAN FD总线)设计,在提供高静电放电(ESD)和浪涌防护的同时,保持低结电容以保障信号完整性,满足工业级宽温环境的可靠性需求。

一、产品核心定位与设计目标

该器件的核心设计目标是解决高速信号线路的ESD防护矛盾:既要有效抑制静电和浪涌对电路的冲击,又不能因防护器件引入过高电容导致信号反射、衰减或传输延迟。针对CAN FD总线(工作电压适配24V级别),其双向防护结构、低电容特性与工业级宽温能力,精准匹配汽车电子、工业自动化等场景的严苛需求。

二、关键电气参数解析

1. 防护性能参数

  • 双向极性:支持信号线路正负方向的ESD/浪涌防护,无需额外设计方向匹配电路。
  • 反向截止电压(Vrwm):24V,与CAN FD总线典型工作电压范围兼容,正常工作时器件截止,不干扰电路功能。
  • 钳位电压:37V(浪涌触发时),可将过压钳位在安全范围,避免后端IC因过压损坏。
  • 峰值脉冲电流(Ipp):3.5A@8/20μs(标准浪涌波形),峰值脉冲功率(Ppp)133W,满足一般工业/汽车场景的浪涌防护需求。
  • ESD防护等级:符合IEC 61000-4-2标准,支持±25kV接触/空气放电,覆盖人员接触、设备插拔等常见静电冲击场景。

2. 信号完整性参数

  • 结电容(Cj):2.5pF(双路配置下每路约1.25pF),远低于传统ESD器件,可避免CAN FD总线(最高10Mbps速率)的信号反射或衰减,保障数据传输质量。

3. 可靠性参数

  • 反向漏电流(Ir):50nA(低漏电流),正常工作时对电路功耗影响极小,不干扰信号电平。
  • 工作温度范围:-55℃~+150℃,符合工业级与汽车级温度标准,可在发动机舱、户外工业设备等极端环境下稳定工作。

三、封装与集成特性

ESD2CANFD24DBZR采用SOT-23(DBZ)3引脚封装,体积紧凑(约1.6mm×1.0mm×0.8mm),适合高密度PCB设计(如汽车ECU、工业控制器的小型化模块)。表面贴装工艺便于自动化焊接,降低生产难度与成本。

四、典型应用场景

1. 汽车电子领域

  • CAN FD总线接口防护:应用于汽车ECU(动力总成、车身控制等)的CAN FD端口,应对车内静电放电与浪涌干扰,宽温能力适配发动机舱等高温环境。

2. 工业自动化系统

  • 工业CAN FD网络防护:用于传感器、PLC、机器人控制器的CAN FD接口,防护车间内的静电冲击与电源浪涌,保障工业网络稳定通信。

3. 高速通信设备

  • 通用高速信号防护:适用于USB、以太网等高速数据接口的ESD防护,低电容特性不影响10Mbps以上速率的信号传输。

五、核心优势总结

  1. 高速信号兼容:低结电容(2.5pF)保障CAN FD等高速信号完整性,无信号衰减/反射问题。
  2. 高防护可靠性:±25kV ESD防护+3.5A浪涌能力,满足IEC 61000-4-2标准,适配严苛环境。
  3. 工业级宽温:-55℃~+150℃工作范围,覆盖汽车、工业等极端温度场景。
  4. 紧凑易集成:SOT-23小封装,节省PCB空间,便于高密度模块设计。

该器件通过平衡防护性能与信号完整性,成为CAN FD总线及高速信号线路ESD防护的优选方案,适用于对可靠性与信号质量要求较高的汽车、工业等领域。

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
