PESD1CAN 产品概述
一、产品简介
PESD1CAN 为双路双向瞬态抑制二极管（TVS），专为汽车及工业现场的信号线（如 CAN 总线）提供浪涌、雷击及静电放电保护。器件典型工作反向截止电压 VRWM 为 24V，具有低漏电流和较小结电容，能在有限空间内实现高效的瞬态能量吸收。
二、主要电气参数
- 极性：双向（适用于双向信号线保护）
- 通道数：双路
- 反向截止电压 VRWM：24V
- 击穿电压 VBR(min)：≈26.7V（典型 26V 区间）
- 钳位电压 VC：50V（瞬态时最大钳位电压）
- 峰值脉冲电流 Ipp：6A（8/20μs）
- 峰值脉冲功率 Ppp：420W（8/20μs）
- 反向漏电流 Ir：500nA（高阻态低漏）
- 结电容 Cj：30pF（适合高速信号线）
- 防护等级：符合 IEC 61000-4-2 / IEC 61000-4-4 / IEC 61000-4-5 规范
- 封装：SOT-23，品牌：DOWO（东沃）
三、功能与应用场景
PESD1CAN 能快速钳位瞬态电压并吸收浪涌能量，常用于：
- 汽车 CAN/LIN 总线、诊断接口保护
- 工业现场总线、防护终端与控制器接口
- 通信设备、继电器驱动与电源旁路的瞬态保护
四、封装与 PCB 布局建议
- SOT-23 小封装，适合空间受限的模块化设计。
- 建议将 TVS 靠近受保护端口（如 CAN 收发器引脚）放置，减少引线感抗与走线长度。
- 为降低对信号完整性的影响，双路 TVS 的接地应通过短而粗的回流路径接至公共地。
五、选型要点与优势
- 双向、双路设计便于直接对称保护差分信号，无需外加耦合电容或桥接器件。
- 30pF 结电容在保证 ESD 抑制的同时，降低对高速差分信号的影响。
- 低漏电流（500nA）适用于对待机功耗敏感的系统。
- 满足 IEC-ESD/EFT/Surge 标准，可靠性高，适合汽车级与工业级应用。
如需在特定工作条件下评估钳位性能或热冲击/浪涌寿命，可提供更详细的动态阻抗与能量吸收曲线以辅助电路设计与选型。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
