PESD1CAN-UX-TP 产品概述
一、简介
PESD1CAN-UX-TP 是台舟电子（TECH PUBLIC）推出的一款用于高速数据线和通信总线的瞬态电压抑制元件，封装为小型 SOT-323。器件专为 CAN 总线及其它差分/单端信号线提供静电放电（ESD）和脉冲浪涌保护，兼顾低电容、高可靠性与小型化设计。
二、主要电气参数
- 反向截止电压 Vrwm：24 V
- 钳位电压 Vc（典型）：50 V
- 峰值脉冲电流 Ipp：3 A（8/20 μs）
- 峰值脉冲功率 Ppp：150 W（8/20 μs）
- 击穿电压 Vbr：25 V
- 反向漏电流 Ir：80 nA（常温下）
- 结电容 Cj：10 pF
- 工作温度范围：-55 ℃ ～ +125 ℃
- 防护等级：符合 IEC 61000-4-2（ESD）、IEC 61000-4-4（电快速脉冲）、IEC 61000-4-5（雷击浪涌）规范
三、特点与优势
- 小体积封装（SOT-323），便于用于空间受限的终端和模块化设计。
- 低结电容（10 pF），对高速差分信号（如 CAN、LIN、USB）影响小，保证信号完整性。
- 低漏电流（80 nA），适合对静态功耗敏感的系统。
- 能承受 3 A/8/20 μs 的瞬态冲击，钳位电压约 50 V，有效保护下游器件免受高能瞬态损伤。
- 宽工作温度范围和对 IEC 等级的兼容性，适合车载与工业环境使用。
四、典型应用场景
- 汽车 CAN 总线、车载通信模块保护；
- 工业控制器与现场总线接口防护；
- 通信端口、传感器接口、I/O 端口的静电与浪涌防护；
- 消费电子、仪器设备中需要高可靠瞬态保护的信号线。
五、PCB 布局与使用建议
- 器件应尽量靠近外部连接器或信号入口放置，以降低寄生感抗和走线长度；
- 在保护器与需保护 IC 之间保留最短、最宽的走线，并在接地端设置多过孔迅速引导充放电到地层；
- 对于差分总线，配合小阻值串联保护电阻能进一步改善浪涌能量分配和信号匹配；
- 注意器件主要用于瞬态事件保护，非为持续高电压或大电流通流设计；在系统设计时应确认工作电压与 Vrwm 匹配，以免发生误触发或提前钳位。
PESD1CAN-UX-TP 以其小尺寸、低电容和符合 IEC 防护等级的能力，为基于 CAN 和其它高速信号的产品提供实用且可靠的瞬态防护解决方案。若需进一步的典型特性曲线、封装尺寸或可靠性测试报告，可联系台舟电子获取详细数据手册和应用指导。

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.
