PESD1CAN 产品概述
一、产品简介
PESD1CAN 是 JSMSEMI（杰盛微）推出的一款双向瞬态电压抑制二极管，专为车载总线（如 CAN/LIN）、工业串行接口及一般数据线的静电放电（ESD）与浪涌保护而设计。器件采用 SOT-23 小封装，体积小、性能稳定，适合空间受限且对信号完整性有要求的应用场景。
二、主要特性
- 极性：双向，支持正负瞬态浪涌吸收
- 反向截止电压 Vrwm：24 V
- 钳位电压 Vclamp：60 V（典型）
- 峰值脉冲电流 Ipp：3 A @ 8/20 μs
- 峰值脉冲功率 Ppp：200 W @ 8/20 μs
- 击穿电压 Vbr：33 V
- 反向漏电流 Ir：1 μA（额定条件）
- 结电容 Cj：20 pF，利于高速信号完整性保持
- 符合 IEC 61000-4-2 静电放电防护等级
三、优势与适用场景
PESD1CAN 在高能量脉冲抗扰能力与低漏电、低结电容之间取得平衡，适合用于：车载 CAN 总线保护、工业控制器通讯口、传感器信号线及消费电子的接口防护。其双向结构免去方向判断，方便串口与差分信号保护设计。
四、器件参数说明
典型工作条件下，器件在 24 V 直流工作电压下保持高阻状态；遇到瞬态过压时导通并将电压钳位在约 60 V 水平，从而保护后级电路不受破坏。8/20 μs 浪涌规范下可承受 3 A 峰值脉冲电流与 200 W 瞬时功率。低至 1 μA 的漏电减少对电源与信号线的影响，20 pF 的结电容对高速通讯影响有限。
五、PCB 布局与可靠性建议
- 保护器件应尽量靠近受保护端口布局，缩短导线长度，降低寄生感抗。
- 使用足够的焊盘接地并加宽回流路径以利散热。
- 对于高脉冲能量场景，配合合适的熔断器或限流元件可提高整体系统鲁棒性。
- 进行实际系统级 ESD 测试以验证钳位性能与耐受能力。
六、封装与订购信息
封装：SOT-23，小型化设计便于表面贴装工艺。品牌：JSMSEMI（杰盛微）。型号：PESD1CAN。适合批量生产与替换设计使用。若需更详细的温度曲线、动态阻抗或封装尺寸图，请参考厂家数据手册。
Request for quote
Send RFQ
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.
