PESD1CAN-ES 产品概述
一、产品简介
PESD1CAN-ES 是 ElecSuper（静芯微）推出的一款 SOT-23 封装双路双向 ESD/瞬态浪涌保护器件，专为工业与车载通信接口（如 CAN 总线、LIN、RS-485 及其它差分/单端高速数据线）提供稳健的静电和脉冲干扰防护。器件具有低结电容、低漏电和高峰值脉冲能量吸收能力，能够在保证信号完整性的同时对敏感接口进行有效钳位保护。
二、主要电气参数
- 极性：双向（可对正负极性瞬态进行钳位）
- 反向截止电压 Vrwm：24 V
- 击穿电压（典型）：26.5 V
- 钳位电压（Ipp = 8 A, 8/20 µs）：48 V
- 峰值脉冲电流 Ipp：8 A
- 峰值脉冲功率 Ppp：600 W（8/20 µs 波形）
- 反向电流 Ir：1 µA（典型）
- 结电容 Cj：24 pF（典型）
- 通道数：双路（可同时保护两路信号线）
- 工作温度范围：-55 ℃ 至 +150 ℃
- 抗扰等级：满足 IEC 61000-4-2 ESD 防护要求
- 封装：SOT-23
三、产品特点与优势
- 双向保护：对正负极性瞬态均能快速钳位，适合差分信号线或可反向工作场景。
- 低电容（24 pF）：对高速数据传输影响小，保证信号完整性与带宽。
- 高能量吸收（600 W @ 8/20 µs）：能够承受工业/车载环境中常见的脉冲干扰与静电放电事件。
- 低漏电（1 µA）：在待机或灵敏测量电路中对偏置影响极小。
- 宽温区与稳健封装：-55~+150 ℃ 适配恶劣环境和车规级应用。
四、典型应用场景
- 汽车 CAN/LIN 总线端口保护
- 工业现场总线与 RS-485 接口防护
- 通信设备的差分信号线、数据端口保护
- 工控、智能设备、楼宇控制系统的防雷/防静电方案
五、PCB 布局与使用建议
- 器件应靠近接口或连接器放置，使瞬态电流路径最短，减小 PCB 母线电感。
- 对地导通路径应使用大面积地平面或短回流路径，以降低钳位电压。
- 信号线与器件之间走线尽量短且避免绕行，减少寄生电感与串扰。
- 在高能量环境中，可并联更高能量器件或在输入侧增加慢熔断保险丝以限流保护后级器件。
- SOT-23 封装的焊盘设计应遵循厂商推荐封装尺寸，保证良好焊接与热散性能。
六、选型与采购注意事项
PESD1CAN-ES 适用于要求 Vrwm ≤ 24 V 的接口保护场景；在选择过程中，应确认被保护线的工作电压和信号带宽，评估结电容对信号的影响。如果系统可能遭受超过 8 A 的单次冲击或更长脉宽的浪涌，建议在器件前端配合限流元件或选用额定能量更高的保护器件。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
