PESD1CAN 产品概述
一、主要特性
PESD1CAN 是一款双路双向瞬态抑制二极管（TVS），封装为 SOT-23，适用于差分数据总线与通信接口的静电和浪涌保护。器件典型参数包括：反向截止电压 Vrwm = 24V、击穿电压 Vbr ≈ 32V、钳位电压 Vc ≈ 50V；峰值脉冲电流 Ipp = 3A，峰值脉冲功率 Ppp = 200W（典型脉冲波形下）；反向漏电流 Ir = 1μA；结电容 Cj = 13pF。工作结温范围 -55℃ 至 +150℃。符合 IEC 61000-4-2/4-4/4-5 抗干扰等级，品牌 KUU。
二、功能亮点
- 双向保护：对称钳位，适合差分总线（如 CAN、LIN 的差分对）以及双向数据线的正负瞬态抑制。
- 低电容（13pF）：对高速信号影响小，适合频率敏感的通信接口。
- 体积小、双路集成：SOT-23 小封装实现两路保护，节省 PCB 面积与装配成本。
- 宽温度与高耐受能量：-55℃～+150℃ 的工作范围和 200W 的单次脉冲能力，满足工业与汽车级环境的瞬态要求。
三、典型应用场景
- 汽车与工业 CAN 总线、控制器局域网接口（差分线保护）；
- 串行数据接口与差分信号链路的浪涌与静电防护；
- 人机界面、外部连接器（USB、以太网PHY 辅助保护）及一般电子产品的输入/输出端防护；
- 需要低电容、低漏电且抗 ESD/EFT/Surge 的场合。
四、推荐电路与 PCB 布局
- 对于 CAN 差分对，应将 TVS 放置于接插件或收发器附近，优先靠近保护节点，采用最短、最宽的焊盘连接以降低寄生电感。
- 双路器件可配置为线路对地或线间夹位（根据系统需求）：若采用线间夹位，应确保器件的额定电压与总线正常偏置相容。
- 与滤波器（共模电感、差分电容）协同使用可增强传导与辐射抗扰能力。
- 散热注意：若系统存在重复高能脉冲，应评估器件温升，并考虑热扩散或外加大功率保护方案。
五、使用注意事项
- 钳位电压约 50V，非无限小；遇极高能量或长时间冲击需配合限流元件（熔断器、阻尼、电感）或选用更大能量等级的保护器件。
- 反向截止 24V，适合多数 12V/24V 系统，但在有更高工作电压或复杂共模偏置的场合需确认与收发器兼容性。
- 结电容虽低但非零，极高速信号仍需评估对信号完整性的影响。
- 对重复脉冲能量、热循环及长期可靠性有特殊要求时，建议按实际工况做功率循环测试与寿命评估。
总结：PESD1CAN 以其双路双向设计、低电容与符合 IEC 抗扰等级的特性，适合用于 CAN 总线及多种差分/双向通信接口的瞬态保护。合理的 PCB 布局与配套限流/滤波措施能进一步提升系统的抗扰度与可靠性。

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.
