PESD1CAN,215-ES 产品概述

一、产品简介

PESD1CAN,215-ES 是 ElecSuper(静芯微)推出的一款 SOT-23 封装双路双向瞬态电压抑制器(TVS/ESD 保护器件),专为差分数据总线与车用/工业接口的静电与浪涌保护设计。器件具有双向极性、工作电压 24V、钳位电压 42V、峰值脉冲电流 8A 与峰值脉冲功率 340W,适合保护 CAN 总线、通信接口及其它易受静电冲击的线路。

二、主要性能特点

  • 双向保护:对正负瞬态脉冲均能有效钳位,适用于差分信号线(如 CAN_H/CAN_L);
  • 工作电压(Vrwm):24V,适应 12V/24V 系统共模电平范围;
  • 钳位电压:42V(典型),在冲击事件中有效限制线路电压,保护后级器件;
  • 峰值脉冲电流/功率:Ipp 8A,Ppp 340W,能承受常见静电与浪涌事件;
  • 击穿电压:28V(典型),反向电流 Ir 极小:100nA(在 Vrwm 下),有利于低泄漏应用;
  • 低结电容:Cj ≈ 18pF(典型/每路),对信号完整性影响较小,适合高速差分总线;
  • 工作温度范围宽:-40℃ 至 +125℃,满足车规级与工业级环境;
  • 满足 IEC 61000-4-2 ESD 抗扰度规范(产品通过相应测试认证)。

三、典型应用场景

  • 汽车 CAN 总线(车载控制器、车身电子、诊断接口);
  • 工业通信与现场总线保护(如 RS-485、差分信号链路);
  • 消费电子输入/输出接口、外部连接器与用户可触及表面防护;
  • 需要双路保护且对封装尺寸、成本有要求的嵌入式系统。

四、封装与布局建议

  • 封装:SOT-23,双路集成,节省 PCB 面积,便于自动贴装与回流焊接;
  • 布局建议:将器件尽量靠近外部连接器或保护点放置,缩短信号走线与焊盘到器件的距离;采用粗短接地回路或地平面,并在必要处增加接地导通孔(vias)以降低感抗;避免在 TVS 与敏感接收端之间放置大电感或长走线,以减小钳位响应延迟与振铃。

五、典型电路接法

  • 差分总线(例如 CAN):通常采用双路并列保护,分别将 CAN_H 与 CAN_L 每一路通过 PESD1CAN,215-ES 一路对地或两路相互保护(视设计而定);由于器件为双向型,可直接并联在信号线两端以钳制正负脉冲。
  • 推荐在敏感器件与保护器之间保留适当的串联阻抗(小电阻或滤波网络),以改善抑制性能与信号匹配。

六、可靠性与选型注意

  • 在选型时注意 Vrwm(24V)与系统最大工作电压匹配;钳位电压 42V 要低于被保护器件的耐压门槛;
  • 结电容 18pF 对高速信号会有一定影响,若用于非常高带宽(数十 MHz 以上)应用,需评估信号完整性;
  • 温度范围与 IEC 61000-4-2 认证保证了在恶劣环境与静电冲击下的可靠性,但在强浪涌(如汽车感生大能量冲击)场景下应结合熔断器或浪涌抑制器共同设计。

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
