PESD1CAN 产品概述
一、产品简介
PESD1CAN 是富芯森美（FUXINSEMI）推出的一款双路双向瞬态抑制二极管（ESD保护器件），封装为 SOT-23，专为差分数据线和通讯总线（如 CAN 总线）提供静电放电（ESD）和浪涌保护。器件体积小、响应快，适合空间受限且需高可靠保护的应用场景。
二、主要规格
- 极性：双向
- 反向截止电压 Vrwm：24 V
- 击穿电压 Vbr：31.5 V
- 钳位电压：60 V（典型）
- 峰值脉冲电流 Ipp：6 A（单次脉冲）
- 峰值脉冲功率 Ppp：360 W
- 反向电流 Ir：≤500 nA
- 结电容 Cj：15 pF（典型）
- 通道数：双路
- 工作温度范围：-55 ℃ ~ +125 ℃
- 防护等级：符合 IEC 61000-4-4、IEC 61000-4-5、IEC 61000-4-2
三、性能亮点
PESD1CAN 在保持低结电容（15 pF）的同时提供高能量吸收能力（360 W 瞬态功率），对高速信号线影响小，能有效抑制静电冲击与雷电、开关瞬态引起的浪涌。双向结构使其可直接用于差分信号线，无需串联电阻或偏置改动。
四、典型应用
适用于汽车电子（CAN/LIN 总线前端）、工业通讯接口、现场总线、控制器、网关、传感器节点以及任何需要在有限空间内对差分或双向信号进行抗 ESD/浪涌保护的场合。
五、布局与使用建议
建议元件靠近外部连接器或受保护引脚放置，走线尽量短且直，器件地线应可靠连接至低阻抗接地平面；若为多层板，保护器与地之间建议配合热盲孔或多点接地以提高散热和吸能能力。对于高速差分线，注意保持阻抗连续，避免在保护器附近增加过多寄生。
六、可靠性与选型提示
器件工作温度覆盖 -55 ℃ 至 +125 ℃，满足恶劣环境使用；反向漏电小（≤500 nA），适合对泄漏敏感的系统。选型时确认 Vrwm 与系统总线静态电压匹配（此器件 Vrwm=24 V），以及钳位电压和吸收能量满足系统瞬态耐受要求。

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.
