PESD1CAN 产品概述
一、产品简介
PESD1CAN 是 GOODWORK（固得沃克）推出的一款双向瞬态抑制器（TVS/ESD）器件，采用 SOT-23 小型封装，专为汽车和工业现场总线（如 CAN）及其它差分信号线提供高性能静电放电（ESD）和浪涌保护。器件在设计上兼顾低结电容与高脉冲能量吸收能力，适合高速通讯接口的直接并联保护。
二、主要性能参数
- 极性：双向（无极性限制，可双向钳位）
- 反向截止电压 Vrwm：24 V
- 击穿电压：25.4 V
- 钳位电压：70 V（典型）
- 峰值脉冲电流 Ipp：3 A
- 峰值脉冲功率 Ppp：200 W（典型脉冲条件下）
- 反向电流 Ir：≤500 nA（常温）
- 结电容 Cj：9 pF（适合高速信号）
- 工作温度范围：-55 ℃ 至 +125 ℃
- 防护等级：符合 IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5 标准
三、产品亮点
- 小封装、高密度：SOT-23 体积小，便于贴片自动化装配，适合空间受限的终端或模块板。
- 低电容：9 pF 结电容对差分总线和高速通讯影响小，保持信号完整性。
- 双向保护：能同时限制正、负方向瞬态电压，适用于差分对或无固定极性的线路。
- 高可靠性：低泄漏（≤500 nA）和宽温度范围，适合汽车级及工业级应用环境。
- 综合抗扰能力：通过多项 IEC 抗干扰测试，能有效对抗 ESD、EFT 与浪涌。
四、典型应用场景
- 汽车 CAN 总线（CAN-FD、标准 CAN）保护
- 工业现场总线（如 RS-485、差分信号）
- 人机界面、控制器 I/O 端子、传感器线缆入口
- 任何需兼顾低电容与双向瞬态保护的信号通道
五、封装与安装建议
- 封装：SOT-23，适配常规 SOT-23 PCB 封装库。
- 布局建议：器件应尽量靠近外部接口或连接器放置，走线短且粗，靠近保护点实现最快的旁路路径。双向器件两端直接并联于被保护线路或差分对上。
六、可靠性与合规
器件通过 IEC 61000-4-2（ESD）、IEC 61000-4-4（EFT）和 IEC 61000-4-5（浪涌）等标准测试，适配汽车与工业场景的抗扰要求。良好的温度稳定性和极低的静态漏电，保证长期工作可靠性。
七、选型与注意事项
- 在选型时确认系统最大工作电压与 Vrwm（24 V）匹配；若系统常态电压接近 Vrwm，应评估安全裕量。
- 钳位电压 70 V 为典型峰值，需确保下游器件能承受该能量或配合串联限流措施。
- 对于高能量冲击或需要更高 Ipp 的场合，建议并联或选择更大功率等级的保护器件。

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.
