PESD1LIN 产品概述
PESD1LIN 是 DOWO（东沃）推出的一款面向接口和信号线瞬态保护的双路双向瞬态抑制二极管（TVS/ESD 抑制器），采用 SOD-323 表面贴装封装，专为工业和消费类电子设备中的静电放电和浪涌脉冲保护设计。
一、主要参数
- 极性：双向
- 工作反向截止电压 Vrwm：15 V / 24 V（两种电压等级）
- 击穿电压 VBR(Min)：15V 级 → 17.1 V；24V 级 → 25.4 V
- 钳位电压 VC（典型）：15V 级 → 44 V；24V 级 → 70 V
- 峰值脉冲电流 Ipp：3 A（条件：指定波形）
- 峰值脉冲功率 Ppp：160 W（单脉冲）
- 反向电流 Ir：≤ 50 nA（常温）
- 结电容 Cj：约 30 pF（适合高速信号线）
- 通道数：双路（双线保护）
- 工作温度范围：-40 ℃ ～ +85 ℃
- 防护等级：满足 IEC 61000-4-2 ESD 抗扰度要求
- 封装：SOD-323（小体积、适合 SMT）
二、产品特性
- 双向 clamps，能在正反向突发电压下对称钳位，适合 USB、串口、I/O 口等双向信号保护；
- 低漏电流（Ir ≤ 50 nA），对高阻输入或待机功耗敏感的电路影响很小；
- 低结电容（≈30 pF），对高速信号（如 USB、串行总线）干扰小；
- 高频响应快，能吸收 IEC 61000-4-2 静电放电冲击及一定的浪涌能量；
- SOD-323 小封装，节省 PCB 面积，便于贴片加工。
三、典型应用
- 手机、平板、可穿戴设备等便携终端的接口保护；
- USB、HDMI、以太网等高速数据线静电防护；
- 工业控制、仪表、通信设备的 I/O 口、传感器线防护；
- 汽车电子（非车规环境下）和消费电子的浪涌/ESD 抑制。
四、封装与可靠性
PESD1LIN 采用 SOD-323 封装，适配常见的 SMT 生产流程。器件在额定温度范围内长期工作稳定，符合 IEC 61000-4-2 抗静电放电规范。实际设计时建议参考厂家提供的典型浪涌测试曲线和热阻数据，以确认在目标波形与能量条件下的可靠性余量。
五、典型电路与布局建议
- 器件应尽可能靠近被保护的连接器或接口布置，减小走线感应电感与串联阻抗；
- 对地走线应短且宽，优先使用连续地平面；
- 对于高速差分线，保证两路保护对称布置，避免单边接地产生共模干扰；
- 在高能量应用中可与串联电阻、滤波元件配合，以分担能量并改善浪涌响应。
六、订购与注意事项
器件型号：PESD1LIN，品牌：DOWO（东沃）。选型时确认 Vrwm 电压等级（15 V 或 24 V）、封装和环境工作温度。对于有车规或更高浪涌要求的场景，请与供应商确认更高能量规格或车规等级产品。若需批量采购或索取器件数据手册（包含 IV/VC 曲线、典型测试条件与封装尺寸），建议联系 DOWO 授权渠道获取原厂资料。

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.
